It’s an Immediately-Invoked Function Expression, or shorter: IIFE. It executes immediately after it’s created.
This pattern is often used when trying to avoid polluting the global namespace, because all the variables used in the function are not visible outside its scope.

Can someone please help me with this code by looking over it for something obvious? The problem seems to be that the embedded JavaScript code is not being executed and, therefore, the PHP code is also skipped. Both, the HTML and the PHP files are in the root directory.
html/js:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>jQuery AJAX test form</title>
<script src="js/jquery.min.js"></script>
<link href="css/bootstrap.min.css" rel="stylesheet">
<script src="js/bootstrap.min.js"></script>
</head>
<body>
<div class="container">
<div id="contacts">
<div class="row">
<div class="col-sm-offset-3 col-sm-6">
<p> </p>
<p>Some header message here</p>
<p> </p>
<form name="contact" class="well" id="contact">
<legend>Contact Form</legend>
<div class="control-group">
<div class="controls">
<input type="text" class="form-control" placeholder="Name" id="name" />
<p class="help-block"></p>
</div>
</div>
<div class="control-group">
<div class="controls">
<input type="email" class="form-control" placeholder="Email" id="email" required/>
</div>
</div>
<div class="control-group">
<div class="controls">
<textarea rows="10" cols="100" class="form-control" placeholder="Message" id="message" style="resize:none"></textarea>
</div>
</div>
<div id="success"> </div>
<button type="submit" class="btn btn-primary pull-right" id="submit">Send</button>
<button type="reset" class="btn btn-default pull-right" id="res">Reset</button>
<br />
</form>
</div>
</div>
</div>
</div>
<script>
$(function() {
$("button#submit").click(function(event){
event.preventDefault();
$.ajax({
type: "POST",
url: "process.php",
data: $('form.contact').serialize(),
success: function(){
alert("success");
},
error: function(){
alert("failure");
}
});
});
});
</script>
</body>
</html>
php:
<?php
if (isset($_POST['name'])) {
$name = strip_tags($_POST['name']);
$email = strip_tags($_POST['Email']);
$message= strip_tags($_POST['message']);
echo "Name =".$name."</br>";
echo "Email =".$email."</br>";
echo "Message =".$message."</br>";
echo "<span class=\"label label-info\" >your message has been submitted .. Thank you</span>";
}
?>

Change your selector from...
$("button#submit").
to.
$("#submit").
|
|
|
|

Nope. It now enters the ajax code, but does not access the php code. Thx for the tip.

try debugging your error handler to see what is happening. I would change the error function to receive the three different parameters and then add a breakpoint on the error handler in whatever browser you are using.
error: function(xhr, status, error){
}

Hi folks,
I just started working on a very interesting project as part of my university research for 3D visualization of earth's surface in 3D (not 3D modeling but real 3D!) using nVidia 3D vision in browser environment. I'm planning to use one of web-based javascript mapping platforms (like open layers or leafletjs) as a base and develop necessary modules for 3D visualization. I have all necessary data (2 image pairs for a test area created from satellite image and Digital Elevation Model) and looking for information on platform, modules and libraries you might know that can help me build this or even any already developed tool you know. I would also appreciate if you mention any document, resource or guide you can share or if you have any comment, advice or ideas.
In case you are interested in being part of this tiny but fun project, you can contact me on the following Email:
T E Z a-t A B 0 d-o-t O R G (without space! third character after at sign is "0" (zero) and not "O" (the letter))
PS: here is a demo of nVidia's tech on browser for those who have access to 3D glasses and graphics card (you should choose 3D vision tab in gallery and turn your 3D feature ON to see it):

I already made a post at Superuser http://superuser.com/questions/800325/how-to-make-google-search-look-dumb[^]
I will summerize here:
[1] http://i.stack.imgur.com/ZN60B.jpg
My point is i do not want to see torrent sites in the search results,so if someone searches Google or any other search engine this phrase(-torrent-download-watch) should be automatically and invisibly added.
[2] http://i.stack.imgur.com/4mUSt.jpg
And one of the answers was this userscript written by krowe:
function GM_main () {
window.onload = function () {
var targ = window.location;
if(targ && targ.href && targ.href.match('https?:\/\/www.google.com/.+#q=.+') && targ.href.search("/+-torrent/+-watch/+-download")==-1) {
targ.href = targ.href +"+-torrent+-watch+-download";
}
};
}
function addJS_Node(text, s_URL, funcToRun, runOnLoad) {
var D=document, scriptNode = D.createElement('script');
if(runOnLoad) scriptNode.addEventListener("load", runOnLoad, false);
scriptNode.type = "text/javascript";
if(text) scriptNode.textContent = text;
if(s_URL) scriptNode.src = s_URL;
if(funcToRun) scriptNode.textContent = '(' + funcToRun.toString() + ')()';
var targ = D.getElementsByTagName('head')[0] || D.body || D.documentElement;
targ.appendChild(scriptNode);
}
addJS_Node (null, null, GM_main);
But the script is not working at all. I copied it to tampermonkey , tried it several times no luck.I need some help please.
I will be happy if this script can atleast work in YouTube,Bing and Yahoo.
Thank you in advance.

My aim is to block torrent sites from google search results.I don't want others(family members) to notice the tampering.

You can contact your ISP and ask them to block torrent sites.

I am creating java web application using netbeans.

I would suggest you search google for examples.
There are only 10 types of people in the world, those who understand binary and those who don't.

I would recommend that you first use the Java[^] forum for this question. You will most likely have to use some form of BLOB.
|
|
|
|
|
You can use java to serialize the image object and then save it to the database. This link should help

Please first try search over internet, if you didn't find help then ask to community.

I made a button in Java Script, and I'm trying to figure out how to turn off the -webkit-appearance so Safari IOS won't turn the button into a rounded button. I found borderRadius.
I want put it inline, instead of modifying the class in the css file, I just need it in one spot.
I looked around but didn't really find anything, most searches produced beginner stuff.
var input_Close = document.createElement("input");
input_Close.id = "_bt_pv_close";
input_Close.type = "button";
input_Close.className = "g-button black";
input_Close.style.width = '112px';
input_Close.style.height = '32px';
input_Close.style.borderRadius = '0';
input_Close.style.fontSize = "1.0em";
input_Close.value = "close";
input_Close.size = "30";
input_Close.onclick = function () { sm_unload_Modal_PhotoViewer(); };
div_Close.appendChild(input_Close);
|
|
|
|
|
Why you are not adding whole style to the object in single line of code!
|
|
|
|
|
I was a complete newbie to writing HTML in the DOM, and I sort of used that style as the next step of advancement.
I couldn't remember the attribute and could not find it through search. I knew there was a one liner for inline style.
I was hoping to keep it the same, but I'll convert to your post example.
Thanks for the reminder!

Can you please use following:
var div = document.createElement('div');
div.setAttribute('style', 'width:330px; float:left');

Hi,
I'd like help to complete this script I'm working on. so for it works but I'm strugling to incorporate theremaining three conditions:
1-The same character may not appear more than twice in a row (Kabooom1)
2-Not more than two sequencial alphanumeric characters are permited (Ab123cym)
3-Black list some words like:(Mark, London)
Any help would be appreciated.script as below
=========================================
<script type="text/javascript">
function checkForm(form)
{
if(form.username.value == "") {
alert("Error: Username cannot be blank!");
form.username.focus();
return false;
}
re = /^\w+$/;
if(!re.test(form.username.value)) {
alert("Error: Username must contain only letters, numbers and underscores!");
form.username.focus();
return false;
}
re = /.{8}/;
if(form.pwd1.value != "" && form.pwd1.value == form.pwd2.value)
if(!re.test(form.pwd1.value)) {
alert("Error: Password must contain eight characters Only, Try again!");
form.pwd1.focus();
return false;
}
if(form.pwd1.value !== "" && form.pwd1.value == form.pwd2.value) {
if(form.pwd1.value.length >= 9) {
alert("Error: Password must contain eight characters Only, Try again!");
form.pwd1.focus();
return false;
}
if(form.pwd1.value == form.username.value) {
alert("Error: Password must be different from Username!");
form.pwd1.focus();
return false;
}
re = /[0-9]/;
if(!re.test(form.pwd1.value)) {
alert("Error: password must contain at least one number (0-9)!");
form.pwd1.focus();
return false;
}
re = /[a-z]/;
if(!re.test(form.pwd1.value)) {
alert("Error: password must contain at least one lowercase letter (a-z)!");
form.pwd1.focus();
return false;
}
re = /[A-Z]/;
if(!re.test(form.pwd1.value)) {
alert("Error: password must contain at least one uppercase letter (A-Z)!");
form.pwd1.focus();
return false;
}
} else {
alert("Error: Please check that you've entered and confirmed your password!");
form.pwd1.focus();
return false;
}
alert("You entered a valid password: " + form.pwd1.value);
return true;
}
</script>

<p><input type="submit"></p>
</form>

The same character may not appear more than twice in a row (Kabooom1)
If it matches the regular expression /(\w)\1/, then you have repeated characters.
Not more than two sequential alphanumeric characters are permitted (Ab123cym)
Not easy with a regular expression. Try something like:
function limitSequentialCharacters(value, limit) {
var sequentialCount = 0;
var prevChar = value.charCodeAt(0);
for (var i = 1; i < value.length; i++) {
var char = value.charCodeAt(i);
if (char === prevChar + 1) {
sequentialCount++;
if (sequentialCount === limit) {
return false;
}
}
else {
sequentialCount = 0;
}
prevChar = char;
}
return true;
}
Blacklist some words like: (Mark, London)
You can either use a regular expression like /^Mark|London$/i, or check the input against a list of blacklisted words.

You really need to do this in server side code by calling a webservice. Client side validation can always be hacked.

Hi All
Can we use java-script/JQuery for interfacing with Hardware device API installed on client system.

No, that would break the security barrier between a browser and client system.

The answer is that it depends on what you are doing.
For instance if you are writing application or server side javascript (node.js[^]) then the answer is yes you can do this.
Another example is writing mobile applications written in HTML and javascript for mobile platforms. In this case you can use phonegap[^] which will give you access to certain hardware features of the device.
If you are purely doing web development with pages delivered from a server then the answer will be No (for now) as it violates the sandbox security put in place by the browser.
