Fire A Change Event (Prototype Library In Use)
Oct 29, 2010
I'm working on a unit test for a javascript library that has several handlers. I wish to fire those handlers in a "natural" way, by raising an event that gets caught. I am having trouble creating an event that gets caught in Firefox.I do development in Firefox to take advantage of Firebug, but the software is for a closed intranet and IE 7 is the required browser (we support IE 8 insofar as we force it to IE 8 mode). This policy predate my hire, I'm trying to get the software to a browser agnostic state - first I have to replace an ActiveX object known as MeadCo Script X - but that's a whole other issue.Anyway I need to raise events, specifically onchange events in Firefox. I have this so far...
Code javascript:
function fire(el, ev) {
el = $(el);Â
if (typeof(el.fireEvent) != 'undefined') { // IE
[code]...
Prototype library is in use for this project, though I haven't used it for this particular corner case.

I am developing a website with perl cgi, HTML, JavaScript and sas SQL.
In html page, there are few drop down list, different item of witch, will call specific cgi file to create new webpage. Those are all working very good.
Now, I added search function, with witch the value entered to text box has to be send, when clicking submit button. The URL of cgi was on the form action.
But something happens. It did not go to the URL of action, but go to the URL of previous one the on-change event did.
Code example:
<form name=change>
<select name=sel1 on change='location=this.options[selected].index'>
<option value=change1.cgi?....>chg1</option>
<option value=change1.cgi?....>chg2</option>
[Code]....
After creating search form by entering value into text box and submitting the form, it did not call search.cgi. If on change event happened before, it will go to the same URL.

I have a <select> object that i've set up an onchange event that fires
in IE fine when I use the cursor up and down in the list, but If I use
the cursor up and down in Firefox the event doesn't seem to fire until
I've left the field....If i use the mouse all is fine, only when using
the cursor keys does it not fire the onchange event in FF.

I've been using the prototype.js library[1] to create classes. Something like:
var Sortable = Class.create();
Sortable.prototype = {
initialize: function(element) {
//...
},
// more methods...
}
All of my methods are instance methods. What is the tidiest way to
create class methods and variables?

I think I'm having a library conflict, but as I don't know javascript, I'm finding it difficult to resolve.
In my document I have an animated navigation using superfish.js [URL].. I also have an accordion menu which uses effects.js and prototype.js. The animated navigation was working before, however after adding the effects.js and protoype.js the menu drop downs only appear and don't animate.
Is this a library conflict and if so howdo I fix it?

I want to execute a function, when a user clicks on a certain button on my page. It works in Chrome, Safari, Opera and FF, but not in IE 9. The jquery-Code looks like this:
$('#mapButton').click(function(event){ ... });
My HTML source code:
<div id="medias">
<div>AUDIO<br /><p id="audioButton"></p></div>
<div>KARTE<br /><p id="mapButton"></p></div>
<div>BILDER<br /><p id="galleryButton"></p></div>
<br style="clear:both"/>
</div>
By Clicking on mapButton the function should follow. I tried it first with the input-Tag, then with the a-Tag and afterwards with the p-Tag. Nothing works at all. I also inserted a return false at the end of my JS function. How to handle it?

I'm new to jQuery. I'm writing some code to show a picture if user clicks on table row. This is the table
<table id="restable" border="0">
<thead><tr>
<th class="cat" width="150"><a href="">Category</a></th>
<th class="brand" width="150"><a href="">Brand</a></th>
<th class="name" width="300"><a href="">Name</a></th>
<th class="weight" width="50"><a href="">Weight</a></th>
</tr></thead>
<tbody id="table">
</tbody>
</table>
The table is filled with this function
function search(sortt,dirt) {
$.getJSON("/jsonsearch.php", {cat: $("select#catselect").val(), brand:
$("select#brandselect").val(), name: $("input#search").val(), sort:
sortt, dir: dirt}, function(j){
$("tbody#table").empty();
var row='';
for (var i = 0; i < j.length; i++) {
row="<tr><td width='150'>"+j[i].cats+"</td><td width='150'>"+j
[i].brand+"</td><td class='name' width='300'>"+j[i].name+"</td><td
width='50'>"+j[i].weight+"</td></tr>";
$("#restable tbody").append(row);
}})
This is the function I put inside $(document).ready()
$("#table td").click(function(){
alert("jhgjgh");
});
The problem is that click event doesn't fire. If I get it working, how do I get the contents of the row that user clicked. I need Name from that row.

I have a snippet of code that's very straight forward. It copies the values of four form fields into another set of form fields (e.g. a billing address to a shipping address). That part works fine, but what I need to have happen is the form fields receiving the data needs to fire their onchange events. They don't do that after the values are changes programmatically. I've tried firing it manually using the onchange() method (as shown below) but that only gives me an error:
$("shipping_address").onchange is not a function
/scripts/registration.js
Line 32
how I can get that onchange event to fire?
Code:
function copyBillingAddress() {
$('shipping_address').value = $F('billing_address').strip();
$('shipping_city').value = $F('billing_city').strip();
[Code]....

I'm attempting to track changes to values I've stored in the localStorage object. From everything thing I've read, this is done by adding a "storage" event listener to the window object but the test file I made doesn't seem to fire the event. I was under the impression that there was pretty good support for this (although I do realize the spec is still under revision).
Code:
if(localStorage) {
// Set Item
button1 = document.createElement("input");
[Code].....
I create two buttons on the page - the first to write a value to localStorage (which works) and the second to clear all values from localStorage (also works). The problem is the event just does not want to fire for me. Even if I set the event on the window's "onstorage" property rather than use addEventListener, no event fires. I've tried in the most recent Chrome, Firefox and Safari browsers.

I'm new to JavaScript and I wrote this code to play with. Oddly, if I
enter text in a box and then press the button, I only get the onChange
event for the text box and not the button's onclick event. But if I
press the button without entering text first, the button click event
does work. What's up?
<html>
<body>
<h3>Events on Buttons and Text Boxes</h3>
<input id="myTextBox1" type="text" onChange="doChange1()" /<br />
<input id="myTextBox2" type="text" onChange="doChange2()" /<br />
<input id="myButton" type="button" onclick="doClick()" value="Click me"
/>
<script type="text/javascript">
function doChange1(e)
{
var val = document.getElementById("myTextBox1").value;
alert("You typed: " + val);
}
function doChange2(e)
{
var val = document.getElementById("myTextBox2").value;
alert("You typed: " + val);
}
function doClick(e)
{
var _num = prompt("Enter a number", "100");
alert("You typed: " + _num); // number converted to string
automatically
}
</script>

I have a form formatted in a table format that has various elements in each row. I want to execute some jquery when the row is exited. When I use focusout() or focusin() I get an event when I switch from one form field to another in the same row - not desired. I just want the event when I switch from one row to the next. Here is some example html:
<tr id="row0"><td><span thmr="thmr_17"><div class="form-item form-type-textfield form-item-rows-0-name">
<span thmr="thmr_16"><input id="edit-rows-0-name" name="rows[0][name]"
[code]....

Let's say I have a page with a counter (with an initial value of zero) and nothing else.
Here's what I want to do:
1) I press and HOLD a key down
2) The counter goes to one
3) I let go of the key
4) The counter still reads one

The Problem: So a user clicks on "web development" for example. This triggers the mousedown function correctly. The user then clicks on "web development" again. This no longer triggers the mousedown event. BUT if you move the mouse around or click a different link it will trigger the function correctly.
The HTML:
<body>
<div id="animate-top"> </div>
<div id="wrapper"><a href="#" class="menu">Graphic Design</a><a href="#" class="menu">Web
Development</a><a href="#" class="menu">Contact Us</a></div>
</body>
The Javascript:
$("a").mousedown(function () {
if (topvisable == 0){topvisable = 1;
$("#animate-top").slideUp('slow');
} else {topvisable = 0;
$("#animate-top").slideDown('slow').delay(1000).slideUp('slow');
}
return false;
});

I have a page divided into various divs, each with an unique id.The user can navigate through these divs using a nav bar at the top of the screen, which is pinned in position with 'position:fixed'.I want to fire a JavaScript event whenever the user views a different div.I have attached an event handler to the links in the nav bar. Correspondingly when the user uses the nav bar to move around the page the desired event always fires.However, if the user uses the address bar to navigate nothing happens, e.g. if someone is viewing "www.mysite.com/#panel1" and then types into the address barthey are moved to the corresponding section of the site, but no event fires.Is there any way to achieve this?

I know how to fire a JavaScript event with the onsubmit code.What I was wondering if it's possible to have a different JavaScript code fire when one changes the value in a select option.For example, something like this:
Code:
<form action="manage.php" method="post" class="manage" onchange="return checkSubmit();">
<fieldset>

I am using GreaseMonkey to load jQuery 1.3.2 (there is a bug with the latest version of jquery and GM) and jQuery UI 1.8.0.I am using jQuery via GM to manipulate the GUI of a content management system. This CMS uses its own JS library to dynamically add stuff to the dom.
Question:How can I target a dom element that was added to the dom via this other JS lib?In other words, the CMS will add a div to the dom, and I am not sure how to tell jquery to wait for these elements to "be there" before applying the jquery goodness. Specifically, I would like to do this:
$(function() {
$('#zen1227').resizable();
});
But "#zen1227" does not "appear" until later via this other JS library.

I have a jquery datepicker that is working fine. I'm using a calendar icon only to start the datepicker and the result (the chosen date)is shown as text - not as an input field. To get this result to show, the user has to click an 'update' functionbuttonfirst, which in my case has nothing to do with the datepicker itself. I know I can use altField to show the result immediately, but that has drawbacks. SoI would like to improve the way it works as follows: when the user picks a date, I want the datepicker to close (which it already does) and the chosen date to show immediately, without the user having to click the 'update' button first. How do I do that? I don't like to use altField, as the user can muck around with the result if they want to -it is an input field after all.
