Oh your right, that did the trick.
I'm new to TypeScript and thought || would of done the job. Guess it would of failed in JavaScript as well.
This TypeScript is harder to write in.
if (files.length > 1) {
event.dataTransfer.effectAllowed = 'none';
this.containerAlert(1);
console.log('drag canceled for too many files');
return false;
}
else if (!fileType.match('^image/jpeg') && !fileType.match('^image/png')) {
event.dataTransfer.effectAllowed = 'none';
this.containerAlert(2);
console.log('drag canceled for not being an image file = ' + fileType.split('/')[1]);
return false;
}
else {
this.containerReset();
console.log('We have a valid image file')
}

I'm missing something here on matching the file type to the string.
I tried !== and !=
It must be related to the order of if and else if in which I'm not understanding the rule.
I've checked the heck out of the strings to make sure it can actually match.
Scratching my head on this one. Don't forget this is TypeScript and not JavaScript.
This doesn't work
if (files.length > 1) {
event.dataTransfer.effectAllowed = 'none';
this.containerAlert(1);
console.log('drag canceled for too many files');
return false;
}
else if (fileType.split('/')[1] != 'jpeg' || fileType.split('/')[1] != 'png') {
event.dataTransfer.effectAllowed = 'none';
this.containerAlert(2);
console.log('drag canceled for not being an image file = ' + fileType.split('/')[1]);
return false;
}
else {
this.containerReset();
event.target.style.opacity = '0.4';
}
This works
if (files.length > 1) {
event.dataTransfer.effectAllowed = 'none';
this.containerAlert(1);<br />
console.log('drag canceled for too many files');
return false;
}
else if (fileType.split('/')[1] == 'jpeg' || fileType.split('/')[1] == 'png') {
this.containerReset();
event.target.style.opacity = '0.4';
}
else {
event.dataTransfer.effectAllowed = 'none';
this.containerAlert(2);
console.log('drag canceled for not being an image file = ' + fileType.split('/')[1]);
return false;
}

This is for my Angular 6 training, in which I'm making a back end SPA for creating a Portfolio of work.
I'm writing this in TypeScript and not JavaScript, because it will just get compiled into JavaScript anyways.
So if a user selects more than one image file, or if the file is not an image file, I would like to cancel the event and send a message.
I've never done this before, or have had a drag and drop event canceled on me in the past using other web sites, so I have no creative ideas on what type of signal or alert to use.
Right now I'm using event.preventDefault() but it doesn't really do anything. I can still drop the files.
And I'm turning the drop target border red which works.
onDragOver(event: any) {
event.preventDefault();
event.stopPropagation();
event.target.style.opacity = '0.4';
let files = event.target.items || event.dataTransfer.items;
if (files.length > 1) {
event.target.style.border = 'dashed 3px #EE6363';
event.preventDefault();
console.log('drag canceled for too many files');
return false;
}
else if (files[0].type !== 'image/jpeg' || files[0].type !== 'image/png') {
event.target.style.border = 'dashed 3px #EE6363';
event.preventDefault();
console.log('drag canceled for not being an image file');
return false;
}
console.log('dragged files', JSON.stringify(files, null, 2));
console.log('dragged file count', JSON.stringify(files.length, null, 2));
}

In native Javascript, calling preventDefault indicates that the drop operation is allowed.
I suspect you need to remove the preventDefault calls from the if blocks, and add it to the end of the method instead.

Thanks Richard.
I ran across that link earlier and should of read in detail earlier.
The whole drag and drop thing is overwhelming at first. I could of used a NPM to do it for me but choose to write code.

I'm trying to pass a Javascript variable to an HTML String variable which passes it to an ActionLink. The script is getting it's value from an "input box".
@{
<!--Script outputs input value-->
<script type="text/javascript"src="http://code.jquery.com/jquery-1.6.1.min.js" >
var sData;
var sDate = function myFunction() {
var sData = document.getElementById("myText").value;
document.getElementsById("demo").innerHTML = sData;
}
</script>
string sData ="I would like to pass the value here";
<!--Demo that script works-->
<p id="demo"></p>
<p id="myData" onclick="myFunction()">

</p>
<label>Monthly Report</label>

}

You don't.
The ActionLink method runs on the server, and generates HTML which is returned to the client, long before any of your Javascript runs, and long before the user has the chance to type anything into the input.
You're going to need to generate the link's href on the client.
Alternatively, wrap the elements in a <form>, change the input name to match the parameter name on your action, and replace the link with a submit button.

1) What I'm trying to do: Uploading a file with aws s3 and then taking the filename and filetype and placing it at the end of the url to save it in sql so that every time the person logs in, it will pull the picture up by user image url

I think your problem starts here at the very beginning on the file upload process.
What this line does:
it allows you to attach to the selected file to upload. You can get the file name, file data, file type here.
depending on the select method, you want to get your files by using
Drag and drop
event.target.items || event.dataTransfer.items
Select
event.target.files
So with a select button, your code would be similar to this:
onSelect(event: any) {
const files = event.target.files,
file = files[0],
fileType = file.type,
fileName = file.Name,
reader = new FileReader;
}
You have the option to grab the image data as well using the FileReader
If you want to read the file data, you add an event listener and use the FileReader.
This will get the image as a base64 string, that you can update the image preview without modification, straignt to the "src".
You can read up on reader.readAsDataUrl and see that there are more options.
let b64Image = '';
this.imageType = file.type;
reader.addEventListener('load', function () {
b64Image = reader.result.toString();
dI.setAttribute('src', b64Image);
b64.setAttribute('value', b64Image);
}, false);
reader.readAsDataURL(file);
After this you on your own. I would just create a model for the record that includes the image, and use http post to contact your NodeJS code to accept the model and write it. I havn't written anything in React yet but this is TypeScript, which is similar to JavaScript and React.
My opinion, your AWS code seems really complicated and over kill for just passing image data

You're setting period.draggable to true, then on the next line you're trying to call it as a function. If it was a function before you set it to true, it isn't one afterwards.

<pre>I have developed an extension for automation. The data available on my web page, i use it to populate the check boxes and radio buttons. There are tabs and i use the data on one tab to auto populate the form elements on another tab.My problem is the tab from which i take the data, does not load all the data at once and when i go to the other tab it fills the data with whatever has been loaded. So if it has 500 records, at times it just loads 75-80 and based on those 75-80 records my automation is working.I want all data to be loaded on my page load for automation to work properly.FYI I can't access the server data so I Manipulate the text/information available on the webpage.Is it possible to do it with extension. I am not much well versed with javascript and working on the extensions on the first time

Hey everyone, today I was making a javascript space invaders game and stumbled upon a problem. When pressing on the right and left keys the ship does not move. I hope somebody can help and thank you in advance 
Below is my code
function startGame(){
gamearea.start();
}
function movePlayer(event){
if(!player.moving){
moveInterval = setInterval(function(){player.move(event);}, 50);
player.moving = true;
}
}
function stopPlayer(event){
clearInterval(moveInterval);
player.moving = false;
}
var gamearea = {
canvas: document.createElement("canvas"),
start: function(){
this.canvas.width = 1100;
this.canvas.height = 600;
this.canvas.style.border = "3px solid gray";
this.canvas.style.display = "block";
this.canvas.style.margin = "auto";
document.body.insertBefore(this.canvas, document.body.childNodes[0]);
this.context=this.canvas.getContext("2d");
player.draw();
window.addEventListener("keydown", movePlayer, event);
window.addEventListener("keydown", stopPlayer, event);
}
}
var player={
x:40, y:580, moving:false,
draw:function(){
gamearea.context.fillStyle="ivory";
gamearea.context.fillRect(this.x+60, this.y, 80, 20);
gamearea.context.fillRect(this.x+95, this.y-20, 10, 20);
},
update: function(d){
this.x+=d;
},
move: function(ev){
gamearea.context.clearRect(this.x, this.y, 80, 20);
gamearea.context.clearRect(this.x+35, this.y-20, 10, 20);
if(ev.keycode== 37 && this.x>0) this.update(-15);
else if(ev.keycode == 39 && this+80<1100) this.update(15);
this.draw();
}
}

I don't get it. You would think that if someone deeplinks to localhost:5000/reviews that the page would display, and not have to use routerLink to get to the page. It works with routerLink, but I can't refresh the page, or hand type the url.
My home works localhost:5000/home and I can type every url route to access the page.
I read the previous post Angular sucks, OK it kind of does. Bu tI'm pretty close to completing my learning project.
Here's my app.module, and below review module. Maybe I missed something here.
Tomorrow I'll recreate this using straight ng and see what happens.
import { BrowserModule } from '@angular/platform-browser';
import { NgModule, NO_ERRORS_SCHEMA } from '@angular/core';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { HttpClientModule } from '@angular/common/http';
import { CommonModule } from '@angular/common';
import { Routes, RouterModule } from '@angular/router';
import { CoreModule } from '../core/core.module';
import { MDBBootstrapModule } from 'angular-bootstrap-md';
import { AppComponent } from './app.component';
import { AdminSharedModule } from '../admin/shared/adminShared.module';
import { HomeSharedModule } from '../home/shared/homeShared.module';
import { PortfoliosSharedModule } from '../portfolios/shared/portfoliosShared.module';
export const AppRoutes: Routes = [
{ path: '', pathMatch: 'full', redirectTo: 'home' },
{ path: 'home', loadChildren: '../home/home.module#HomeModule' },
{ path: 'reviews', loadChildren: '../reviews/reviews.module#ReviewsModule' },
{ path: 'portfolios', loadChildren: '../portfolios/portfolios.module#PortfoliosModule' },
{ path: 'admin', loadChildren: '../admin/admin.module#AdminModule' }
];
@NgModule({
declarations: [
AppComponent
],
imports: [
CoreModule.forRoot(),
BrowserModule,
BrowserAnimationsModule,
CommonModule,
FormsModule,
HttpModule,
HttpClientModule,
ReactiveFormsModule,
MDBBootstrapModule.forRoot(),
AdminSharedModule,
HomeSharedModule,
PortfoliosSharedModule,
RouterModule.forRoot(AppRoutes)
],
exports: [
RouterModule
],
schemas: [
NO_ERRORS_SCHEMA
],
bootstrap: [AppComponent]
})
export class AppModule { }
And my review module
import { CommonModule } from '@angular/common';
import { HttpClientModule } from '@angular/common/http';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { MDBBootstrapModule } from 'angular-bootstrap-md';
import { RouterModule, Routes } from '@angular/router';
import { ReviewsComponent } from './components/reviews.component';
const reviewsRoutes: Routes = [
{ path: '', component: ReviewsComponent }
];
@NgModule({<br />
exports: [
RouterModule
],
imports: [
CommonModule,
FormsModule,
HttpClientModule,
MDBBootstrapModule.forRoot(),
RouterModule.forChild(reviewsRoutes)<br />
],<br />
declarations: [
ReviewsComponent
]
})
export class ReviewsModule { }

Well it works in Angular 6 using ng to create, build and serve the app.
I've determined that it has something to do with .Net Core 2.1 and the webpack, needing a angular router loader.

It was an error in my startup.cs in Configuration. I didn't have the all the routes loaded in the array below.
So it was .net core that was rejecting direct url typing or deep linking.
Maybe I should remove this. But I learned alot of routing and navigation in Angular and will experiment with removing it.
var angularRoutes = new[] {
"/admin",
"/error",
"/home",
"/reviews",
"/portfolios",
"/setup"
};
app.Use(async (context, next) =>
{
context.Response.Headers.Add("X-Frame-Options", "DENY");
if (context.Request.Path.HasValue && null != angularRoutes.FirstOrDefault(
(ar) => context.Request.Path.Value.StartsWith(ar, StringComparison.OrdinalIgnoreCase)))
{
context.Request.Path = new PathString("/");
}
<pre>
await next();
});

So, I'm 16 years old and decided I wanted to learn to code yesterday. The only place where I knew I could, was Codecademy. In school I didn't have any coding experience, so I'm a bit stumped as to what I should be learning. I began with JavaScript and already understand the basics of flow, conditions, functions etc. but nothing nearly enough to actually try to undertake a project myself.
So my questions are: Am I right in choosing JavaScript as my first language (bearing in mind i'm not sure why I want to code, it just seems really fun solving the puzzles, but I would love to, in the future, make something)? And what were your experiences in first learning to code? Was it frustrating, how long did it take you to be confident enough to try to code your first project, which language did you choose, and if you had the chance, would you change your first language?

Javascript is probably a good starting point in learning the general structure of program flow. But as to the future, it largely depends what sort of applications you want to create.
For desktop/Windows I would suggest C#, and there is an excellent free book at .NET Book Zero by Charles Petzold[^].
For web applications C# and Javascript together, plus HTML and CSS. There are some good web tutorials at ASP.NET | The ASP.NET Site[^].
For something quick and easy you could try Python, see The Python Tutorial — Python 3.4.9 documentation[^].
No doubt other members will have further suggestions.

Learning to code is very little about which language you choose and very much about learning to decompose problems.
That said, where you go when you're first starting has everything to do with what sort of learner you are. If you need a structured approach to learning you may find JS is the wrong choice and I would recommend something along the lines of Java or C#. You'll find that JS is exceptionally forgiving, and it will happily push through code that is malformed or just plain wrong and attempt to resolve it into a coherent response. This is not the way to learn to code.
If you really want to dig in, the C/C++ family is where I started, and understanding how those work did wonders for me in terms of learning other languages down the line, but it is absolutely unforgiving.

Welcome to the coding world !
I was also new to coding last year.I was little bit confused regarding which programming language to choose.Then i decided to play with Python.Python is too much fun and addictive.I started with solving simple programming problems. Python made every thing simple and interesting.Later i realized that, it is good time to switch for real world problems.My first ever project was Simple Snake Game using Pygame.I made it just to be cool in front of my friends, but later i got addicted to build such projects.I built more then 10 simple projects that made my day to day life easy like Image to PDF converter, Pyro-Virtual assistant, my own programming language, attendance management system etc.
Later i switched to C and then C++.Now i am on a long and interesting journey of competitive programming.... 
Good Luck!

I'm trying to write a split method regular exspression that will match the text [code] but won't match it if it's wrapped in quotes like this "[code]" How do I write a regular to accomplish that?
--Brian

|
|
|
|
/(^|[^"])(\[code\])($|[^"])/g
This will also capture the character before and after the [code], if any, so you'll need to account for that.
