Internet Explorer 7 + alert() doesn't work - javascript

Can some of you please tell me why a simple alert() isn't working using jQuery 1.4 in Internet Explorer 7, when it's working in all other browsers? It's been driving me crazy now for the last half an hour..!
$(document).ready(function(){
alert("wtf?");
})
This simple example doesn't show an alert in IE7. See for yourself at http://jsfiddle.net/8HQdp/.

Ensure your console doesn't show any errors and correct them if there are any.
Be sure you didn't disable browser prompts on IE
Try using window.alert() - it's possible (though improbable) that another alert() is conflicting with window's.
If you have console support, try console.log(alert); and see what it says. It should be something like:
function alert() {
[native code]
}

I'm using IE8 but with IE7 mode, the alert on http://jsfiddle.net/8HQdp/ still triggers.
Try changing $ to jQuery and host your own jquery.js.
And also try console.log('wtf') before alert so u know whether it's alert or document.ready is broken.

It works in IE 7 mode in IE 8 form me. Takes a while but it does trigger.
I noticed that there is a semi colon missing from the ready function. should be...
$(document).ready(function(){
}); //missing semicolon here
Also, try using the shortcut for the DOM ready function...
$(function(){
// code here
});

Try using window not document.

jQuery return 0 inputs in IE9

I having a strange problem. I am working in Parallels to test a site in IE 9 on Windows 7.
My setup is jQuery 2.1.1, Bootstrap 3.2.
I was validating a form with Parsley which if course worked well in Chrome, but did nothing in IE. When testing further I realized the DOM wasn't even updating at all. So I stripped it out down to just this to see what was happening:
$(document).ready(function()
{
console.log('ready')
/*
The form submit handler
*/
$('.submit').click(function(){
fields = $('#promo-form').find(':input');
console.log($(fields).length)
});
});
Chrome Console:
ready
15
IE 9 Console (with F12 Developer Tools)
LOG: ready
LOG: 0
I can get IE to recognize some simple selectors like $('input'), $('form') but cannot use jQuery methods to find a collection. All works just fine in Chrome on the Mac.
Any ideas here?
Thank you
Rich
Have you tried :
http://jsfiddle.net/dhyjwg4L/
Just tested in IE 10 / 11, don't have an IE9 machine to hand.
$(document).ready(function () {
alert($("#promo-form :input").length);
});
If you didn't want textareas / buttons remove the : before the input, and they wont be counted.
$('#promo-form').find(':input');
//Combine the selector to make
$("#promo-form :input")
UPDATE : Have now tested this on IE 8-11, and is working on all of them.

jQuery onclick placer doing nothing

I have an input on my index page:
<input type="button" name="goReplaceAll" value="Go" id="allReplaceGo" style="cursor:hand;" />
And an onclick call from jquery:
$(document).ready(function() {
$('#allReplaceGo').click(replaceAll);
});
function replaceAll(){ alert('a'); }
When I click the button, nothing happens. When I instead use onclick="replaceAll()" within the HTML, I get an error: Uncaught ReferenceError: replaceAll is not defined
I am unable to figure out a connection between these errors, or any possible cause.
The code is currently live at http://www.texturepacker.net
Edit: Looks like I get two different results in Firefox and Chrome, Chrome does nothing while Firefox alert('a')'s once the page loads. Now I'm just plain confused?
Edit: Seemingly an unrelated syntax error later in my code was breaking the call. Now replaceAll() is called when the dom loads, my question is now why isn't replaceAll() being launched onclick and instead once the dom loads, am I missing something obvious?
Look like a syntax error here...
Line 196 in you script file says
$(this).("src",tmpSrc);
It is supposed to be
$(this).attr("src",tmpSrc);
Fix that and it should be all fine..
Also on line 7
$('#allReplaceGo').live("click",replaceAll());
is supposed to be
$('#allReplaceGo').live("click",replaceAll);
Also as of version 1.7 .live() is deprecated. try using .on() instead
That happens, probably, because the function replaceAll is outside the jQuery scope.
Try to put her inside the $(document).ready scope.
Your code should look like
$(document).ready(function() {
$('#allReplaceGo').click(function(){
replaceAll()
});
});
function replaceAll(){ alert('a'); }

document.body.onload in Firefox

Okay so I'm using Javascript to set the onload attribute of a page. It works in IE but not Firefox. Does anyone know a fix for this? Neither IE or Firefox is throwing an error. I'm using the Firefox plugin "Web Developer" and it isn't showing any JavaScript errors. Code below: Thanks.
document.body.onload = setRedirect;
function setRedirect()
{
alert("TEST");
}
Change to:
window.onload = setRedirect;
Also see this jsfiddle.

jQuery $ is not a function in Firefox, works in Chrome and works with $(document).ready()

I'm implementing jQuery in a site and am getting the "$ is not a function" in Firefox when I try to use a selector, but $(document).ready() works perfectly right before it. My code looks like this
<script>
$(document).ready(function(){
alert("hi")
}); // Works fine
function showDiv(){
$("#traditionalCC").hide();
}
//Throws error
</script>
Does anyone know why this happens, and why it works in Chrome and Firefox.
The key difference between your two examples (the working and non working ones) is that the first one is using the document ready event. That happens when the page is fully loaded. Not sure when you're other one is getting invoked, but my guess is that it is being called before your <script> tag include for jquery.js itself.
Try
<script>
$(function() {
alert("hi")
}); // Works fine
function showDiv(){
$("#traditionalCC").hide();
}
//Throws error
</script>
Try to use
$(document).ready(function() {
$ = jQuery.noConflict();
});
Fix your script declaration to <script type="text/javascript">
Verify if your script is after the jQuery lib include.
I hope it help.
I have found that sometimes Firefox gets "hosed" and I have to quit and relaunch.
In case anyone comes across this in the future, the problem was FireBug. I uninstalled and reinstalled and the issue went away.

Click event not worked in Firefox

I am using a jquery click function:
Button code
<input type="button" id="myButtton">
Jquery code
$(document).ready(function () {
$("#myButtton").click(function () {
alert("Mybutton");
});
});
This code works in Internet Explorer but does not work in Firefox.
What am I doing wrong?
In the code:
$(document).ready(function(){
$("#myButtton").click(function(){
alert("Mybutton");
});
I believe it's missing another closing brace:
$(document).ready(function(){
$("#myButtton").click(function(){
alert("Mybutton");
});
});
My best guess is that you have other input with the same ID? Try using classes instead, or use jQuery's CSS selector like $('input[type=button]') instead.
I'd also recommend installing FireBug plugin for FireFox if you haven't done so already (http://www.getfirebug.com/). It'll help you debug JavaScript issues like this, and a whole lot more.
Are you sure that element has an id attribute? Or does it have only a name attribute with a value of "myButton". In order to work cross browser the id attribute is mandatory, whereas name is optional (only IE and Opera AFAIK).
N.B.: My answer may seem idiot, but it was not the original poster that added the code example in the question (view edit history).
