I have a two level dependent select function, when level 1 changed, level 2 will change content with level 1, level 2 only change when level 1 "changed", if I use javascript to change the level1 value, level 2 won't change,for exaplme:
$('#level1').val(3);
the level 1 select will change to the option which value is 3, but it won't trigger the change event, therefore level 2 does not change anything, how to change level 1 by and trigger change event.
I'm currently having a problem with getting a change event to fire when changing the values of a select box. I've put together the sample code below to show what I mean.
In IE only, the change event on a select does not seem to fire if the change is made by typing on the keyboard instead of clicking with the mouse. However, when the focus leaves the field, the event fires.
Is it possible to trigger a change event on a select field when the selectedIndex or val is set with jQuery? I've tried it and it doesn't seem to work. I'm attempting to replace a select field with one of my own design. The issue is if i attached a change event to a select field, when the index is changed it needs to fire that event. Basically if a select field is replaced with my list and a seperate script is set on the select list, I need that seperate script to fire without knowing what it is.
creating --Dynamic dependent cascading select using Ajax.It should not use asp .net, I need to add the code in a text field to generate this kind of cascading customized field.eg. initially we need to populate a select list from database. Then, on selecting an option the next select list needs to get populated with corresponding values, then again on selecting..the third list needs to get populated --this should happen dynamically(with no page refresh).

I have an ajax dependent drop down set up for location fields and am having trouble figuring out how to clear the dependent selects if the parent select is changed to blank.I set up a function to clearFields:

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 wanted to create a small DHTML code that created a unordered list of input forms dependent on the number selected from the select dropdown menu. Problem is that it doesn't seem to want to generate the list. I think the variables are within the scope of the function too, and I didn't get an errors from the javascript console when using firebug. The script itself runs, I tested it when I used the old standby alert(); to see if the script was active. Here's the code:
I am having a bit of trouble with a change event. I am trying to make a simple address book that will allow you to add or modify contacts. This is a piece of the code that I am working on.The script runs without error and initializes the form. The click events for the buttons work correctly, but the change event for the select box will not fire. I have been searching for an answer and cannot find one.
var init = function () { var selectCell = document.getElementById("select-box-cell");
$(function(){ $('input').bind('keypress',null,b).bind('change',null,a); }); function a(){
[Code].....
this script bind both keypress and change of the text box to functions b and a. at keypress event handler if user type a char on input box the value of input box change to x and the user char discarded. In this case we expected to run the onchange (change) event because the textbox value is changed BUT this doesn't happen.

I am using jquery validate js for my validation. I need to validate and pass the value for the below senario.
I am having a dropdown box which has 2 option. Option 1 and Option 2.
And I have few checkboxes with same name. Depending upon the dropdown selection it should show/hide some checkboxes. Using javascript and CSS these are working fine.
The problem I am having is with the Select All function. If I check Select All it checks the hidden field also. The requirement is to select only the fields which are visible not the hidden one. Please suggest me how to do this.
Example
Here Value 3 and value 4 are common. If I select option Select Item 1 Value 1 will show and value 2 will be hide. If I select all it should not select value 2. As the name is common its selecting that also. It should not select value 2. This is the requirement

I am working on a class registration system that requires students to register for a main class (101, 102 or 103). The student is supposed to select one main course as well as provide a second choice in case the first is not available. I have two dropdown select fields to capture data
1) Choice -1: 101 / 102 / 103 ( Student needs to select one - Reading the classID from classes table) 2) Choice -2: 101 / 102 / 103 ( If student selects 101 in Choice-1 then the only classes available under Choice-2 should be 102 or 103).
How can I accomplish the above? Further to this there are two fields on the form where I would like to auto populate based on what they have selected in Choice-1 and Choice-2.
For Example: If a parent selects choice1: 101 the child Choice1 field should autopopulate with 100. If a parent selects Choice2: 201 the child Choice2 field should autopopulate with 200
I have been trying to develop a simple method of styling the button on select dropdowns. Basically just positioning a span of the button on a select box that is styled as required.
That is trivial...
What I have so far failed to achieve is to get the select box to show its options when clicking this span - just want to have the select box drop down the options as it normally would.
tried .trigger('click') and .trigger('mousedown') but to no avail...
$("#amount").keydown(function(event) { // Allow only backspace and delete if ( event.keyCode == 46 || event.keyCode == 8 ) { // let it happen, don't do anything } else { // Ensure that it is a number and stop the keypress if ((event.keyCode < 48 || event.keyCode > 57) && (event.keyCode < 96 || event.keyCode > 105 )) { event.preventDefault(); }}});
