Other option for scripting with onclick functionality
<pre> function registerHandlers() {
var as = document.getElementsByTagName('a');
for (var i = 0; i < as.length; i++) {
as[i].addEventListener('onclick', function() {
alert(i);
return true;
});

Hi,
Quick question. Using Java Script to display dynamic htmlpages.
Question on how to make all the fields in a row high lighted in red based on a condition instead of doing each field.
Code below is what we are doing currently to set color for some fields based on condition.
But with a new condition all fields have to be highlighted in Red.
How to do it. There are around 20 fields in the row to conditionally highlight in red.
if (field.entered == 1 && field.pcnt_staged != '100%') {
fldText += '' + field.shipto + '';
}else{
fldText += '' + field.shipto + '';
}
thanks

To highlight a row of what? What I mean by this is that it depends on how you setup the HTML. If you setup HTML that can be modified in a 1 liner in JavaScript and CSS, then my example would work easy. It really depends on how you designed the HTML.
I would imagine that you just create a class in CSS to create the visual effect you need, then add that class to each element that needs to be highlighted.
These elements could have a master element wrapper, in which you would add a new CSS visual effect, that would highlight all the child elements.
<div class="wrapper">
<div class="element">1</div>
<div class="element">2</div>
</div>
Something like this would add the class. Not tested, just off the top of my head
if (field.entered == 1 && field.pcnt_staged != '100%') {
let wrapper = document.getElementByClassName('wrapper');
if (wrapper) {
wrapper.classList.add('red-all');
}
}
<div class="wrapper red-all">
<div class="element">1</div>
<div class="element">2</div>
</div>
In css I think it would be, master element select all child divs within the master.
.red-all > .element {
color: red;
}

thanks for the input.
we are building in a html table and display the results.
var fldText = "There are 10-15 fields in the tables.
So need to highlight all these 15 fields conditionally.

Hello,
I'm looking into taking a course and on the precourse material the question ask...
function NumberFour(value){
let greaterThanFive = false;
// In this exercise, you will be given a variable, it will be called: value
// You will also be given a variable named: greaterThanFive
// Using an 'if' statement check to see if the value is greater than 5. If it is, re-assign greaterThanFive the boolean true.
// Please write your answer in the line above.
return greaterThanFive;
}
How would I know if the value is greater than 5? Is this a trick question... would someone please explain.
Thanks

Quote: How would I know if the value is greater than 5?
Really?
That is the purpose of the course, and the author would have explained the operators and language structure to perform this operation. I recommend taking the course, and also exploring JavaScript language, you can start at MDN; JavaScript | MDN.

I am working on a cep html panels extension and I am facing this known "thorn" of asynchronous code!!! I know that the most secure way is to use promises and async/await, but my problem is that I can't really understand how I can suit my code to promises and async/await. I believe an example based on my code would really help me.
Here is a small example of my code...
JS FILE CODE:
(function()
{
'use strict';
const csInterface = new CSInterface();
const extensionId = csInterface.getExtensionID();
let psDocumentsLength;
function init()
{
themeManager.init();
$(document).ready(function()
{
setTimeout(function(){check_PSDocumentsLength();
setTimeout(function(){reclaim_PSDocumentsLength();
}, 100);
}, 100);
});
};
function check_PSDocumentsLength()
{
var chosenFunction = 'checkDocumentsLength()';
csInterface.evalScript(chosenFunction, function(result)
{
psDocumentsLength = result;
});
};
function reclaim_PSDocumentsLength()
{
if(psDocumentsLength < 1)
{
alert('There is no opened document!!!');
csInterface.closeExtension()
};
};
init();
}());JSX CODE:
function checkDocumentsLength()
{
return documents.length;
};
As you can see, in order to avoid the phenomenon of asynchronous code, I am using nested setTimeout(s). Is there anyone who can explain to me how I can do the same thing but using promises and async/await?
Thank you in advance!!!

Promises really are not that hard. They basically allow you to dynamically attach callbacks to an object, which are execute when you designate within the promise function.
In your case it would look something like this:
function init()
{
themeManager.init();
$(document).ready(function()
{
var promise = new Promise((resolve, reject) => {
try {
var chosenFunction = 'checkDocumentsLength()';
csInterface.evalScript(chosenFunction, function(result)
{
resolve(result < 1);
});
} catch(ex) {
reject(ex);
} finally {
csInterface.closeExtension();
}
}
promise.then(function(value){
if(!value){
alert('There is no opened document!!!');
}
});
promise.catch(function(error){
console.error('checkPSDocument error: ' + error);
});
});
}

Try something like this:
(async function(){
'use strict';
const csInterface = new CSInterface();
const extensionId = csInterface.getExtensionID();
const runEvalScript = (script) => new Promise(resolve => csInterface.evalScript(script, resolve));
const waitForDom = () => new Promise($);
themeManager.init();
await waitForDom();
var psDocumentsLength = await runEvalScript('checkDocumentsLength()');
if (psDocumentsLength < 1) {
alert('There is no opened document!!!');
csInterface.closeExtension();
}
})(); NB: async functions[^] are not supported in Internet Explorer. Neither are arrow functions[^] or promises[^].
let and const[^] are supported in IE11.
If you need to support IE at all, you'll need to use a "transpiler" to convert your code to ES5.

Dear All,
How do i get the client's windows login name in java based web application.

There may be some hacks out there, but unless you're on a domain, that should not be possible and would be considered a security risc.

Have your Java-based web app send a current user object to the client, where it can be interpreted by your JS...?
Not 100% sure what you are asking here.

If you're in an Active Directory environment and your users are on Windows computers, you can use Windows Authentication in IIS in order to automatically use their currently logged in claims principal. I don't know the interface for Java, but I'm sure there is one, and it's trivial using asp.net.

}
let v1 = params[0];
let operator = params[1];
let v2 = params[2];
switch (operator) {
case '==':

I would imagine your issue is here.
It is case sensitive, or perhaps the location is wrong, or it's not registered.
Check the file, and work back to the source of 'ember'

Yes it was case related, I figured that out, but now it says my function is not a helper function any help buddy?
My helper function is as below:
export default () => {
Handlebars.registerHelper('ifCond', function (v1, operator, v2, options) {
alert("hi");
if (params[3]) {
params[0] = params[0].toLowerCase();
params[2] = params[2].toLowerCase();
}
let v1 = params[0];
let operator = params[1];
let v2 = params[2];
switch (operator) {
case '==':
return (v1 == v2);
case '!=':
return (v1 != v2);
case '===':
return (v1 === v2);
case '<':
return (v1 < v2);
case '<=':
return (v1 <= v2);
case '>':
return (v1 > v2);
case '>=':
return (v1 >= v2);
case '&&':
return !!(v1 && v2);
case '||':
return !!(v1 || v2);
default:
return false;
}
});
}
And I am trying to use it as below:
{{#each novi.violations as |noviv index|}}
{{#if (ifCond novv.ViolationId '==' noviv.ViolationId true)}}
{{log 'someVariable'}}
<br />
{{/if}}
{{/each}}
Here is the error that I am getting
sayingember.debug.js:43618 Uncaught (in promise) Error: Compile Error: ifCond is not a helper
Any help buddy?

I understand your question but you posted too much HTML for me to figure out which "td" element your referring to, and you have no comments. Why post so much HTML?
Keep in mind that we can't read your mind when you post your troubled thoughts, and you have to help us along to tell the story again.
But on the other hand, it's really about working within the limitations of React, and using React HTML operators like "if", "switch" and so forth or building a better model to start with. If it's a violationType, then switch with that. I'm sure React has some support for containers and sections to hold the proper HTML based on a violationType for example.
