JQuery :: Change Event Not Firing After Pragmatic Changes
Jul 17, 2010
I've noticed that the change event isn't being fired for me on form elements when the changes are made pragmatically (eg, using the attr() method). For instance, a checkbox's change event fires if I click it, but not if I use .attr('checked', false);
I'm using jQuery 1.4.2 and Firefox 3.6.6. I did notice that the native event handler (as in, adding an onClick attribute to the element manually) doesn't work either, so evidently this is NOT a bug in jQuery.
I just wonder if anyone knows a way around it. I'm particularly interested in catching the change event from form elements after clearing the form.
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.
Here's my code. when you load the page, alert shows up. is there a way to stop that? i only want alert to show when I change the selected item from dropdown list.[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");
I have some ajax gotten content which I want to fire a scroll event on. Its basically a table inside a div, and the div has scrolling enabled. The divs class is data table.
I am trying to run a click event where and if statement is run to check for a certain image being clicked before running code. I set up this if in two ways:

Here is the link to my jquery game. Click on the black square to start, then a click on a grey square to see what I am talking about. The second function I mentioned is the current in the code.[URL]..
I have a 300x150 container div with a small inner div that has a image link button inside..When the user hovers over the button, it currently does .hide on the visible container div and .show on another div.However, I don't want the event to fired instantly, I would like for the animations to take affect 3000 milliseconds after their mouse has entered the button div to prevent the event from firing without the users intention.
I am working on a button that fires a few different fadeIn()'s upon clicking it but nothing is happening. I have same setup working just fine with another button, but this one doesnt do it.
I have a form element that is readonly. <input type="text" id="kfs_acct_1" readonly="false" /> This field is dynamically populated an making it readonly prevents users from changing the value in this field. The problem I have is users click on the field and try to delete it's value. They click in the field and hit their Backspace key. This takes them away from the page to the page from whence they came. Because of the way the form is set up, doing this makes them loose all the data in the form (the one with the readonly box). How can I prevent the Backspace key from fireing and taking the user away from this page? I've tried a few things, but apparently making a field readonly keeps some key events from being seen.
I'll start off by saying I'm a novice developer. I'm building an mvc application and recently started using the jquery hotness. I've set up a right hand nav and bound click events for collapsible panes. Inside one of those divs (action pane) I've bound click events which will open a modal dialog with a form. The form is submitted with $.post(). Then I've used $.get() to refresh several divs with the new content. Once that happens, all of my links begin to fire twice (collapsible panes and the links in the action pane) in ie8 and the latest firefox but not in chrome. I pulled out all the markup and js and put it on a static test site: [URL].
$(function() { //----------------------------------------------onload var viaje; var total;

Basically, when the user selects a trip, or the number of travellers it triggers a table to show with the corresponding options, the problem I have is that in ie7, it doesn't trigger the first time, only the second time. I have seen a few posts saying they have a similar problem, but in their case, it triggers when they unfocus. I have tried using simple javascript to select one of the options manually, hoping it would count as a first change, and that then clicking the first time would do it, but nop.
Ok, so the above code will do the regex when the contents of the textbox changes, but it does not seem to call the checkPrice function I've placed after it does the regex.
I have the above on Change code in a .keyup event and it works as expected.
New to jQuery, I did many searches before posting. This is happening in both IE6 and Firefox 3.0.13. I've gotten the following script to work under strange circumstances (explained below first snippet).
I have some jQuery making ajax requests that works just fine if the server returns a 200 but whenever it returns any error HTTP status none of the events fire. It's happening on more than one request to different servers but I'll just include one example for now:
The request gets made just fine, I can see the response in the net console in firebug and it returns the data I want with a 500 when I do not complete the form correctly. However, it does not fire either the error or the complete function when I get this status, and the ajaxResponse.responseText is undefined when it is logged to the screen. When the form is completed and the request is successfull the success function fires just fine.
im having trouble using JQUERYs animate function. Basicly the div has a mouseover event that slides another div (that is inside the original div) upwards. The first div has a mouseout event that slides the second div downwards and out of view. The problem being that when you hover over the second div it fires the first divs mouseout event. Ive tried googling this and have tried adding some event bubbling but having serious trouble with it. here is the website... [URL] hover over the image and you should see the caption appear, roll over the caption and it goes crazy.
My change function allows users to switch from country to country and get different text and features. It works when changing country selections. But at initial page load, it does not fire jQuery change to set the text for the default / initial country. When I change away and then back to the default/initial country, change fires and shows the proper information and features. I have tried document.ready with a change function both inside the switch selections and outside the change function. Neither work - they don't fire the hide, show and other jQuery in the switch cases at doc ready. Its not clear to me what function will fire the jQuery change function at doc ready. Here's the code. The country selection below is just 2 countries to keep it simple, but actually, there are many.
i am working on a custom drop down list that has hidden #options DIV which is shown when the user clicks on a button. the problem i am having is that the click event does not seem to be attached to the LI elements since they are hidden when the page first loads. if i show the #options DIV when the page loads everything is working as expected.i've tried to attach the click event after i show the hidden UL but that didn't work either.what can i do to make sure the LI click event fires? i tried to put A tag inside of LI and attach click to that but to no avail.
I am using 2 ajax functions in the program. One for login and one for logout.The login one is showUser which is working correctly by using the form onsubmit method, however the logout button (IN BOLD) onclick method is not working.
I have aded window unload event handler to my code. my page calls some function that takes few secs and page then loads in 5-6 secs. while ths page is loading, if user clicks 'x' on browser window, then code inside unload event handler doesnt get executed. if user waits for page to be loaded fully and hten clicks 'x', then unload event handler gets executed. but i want if during loading user decides to click 'x' button, then also unload handler shold get exucted.
I am pasting a sample code that simulates my situation:
I'm working on a quote generator and I'm running into an issue with onChange events not firing when a text field is dynamically populated via a child window. Here's my setup: I have 3 text boxes (quantity, price, markup) that are multiplied together in order to give the total of that product. Each text box has an onChange event [called calculator()] that calls an external javascript file, which handles the multiplication and instantly updates the total of that product. Up to this point, everything works fine - - when I manually edit any of the 3 inputs, the total updates correctly.
However, my problem is that I now have the "price" text box being dynamically populated, and when it updates it is not firing the onChange event attached to it. The text box is being filled by way of launching a child window and running the following code within it:
$(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 have a series of checkboxes on a page and the goal is to run an ajax post each time one of the checkboxes is checked. When the page loads, the first time I click each of the checkboxes everything goes as planned. After I receive the response from my ajax php function and all related events fire, I click the checkbox again and nothing happens. The event listener seems to have stopped functioning.
