JQuery :: Submit Function Not Always Trigger Live Or Bound Handler
Sep 25, 2010
I have this boiled down to the following code: [URL]. I have two text inputs in a form, and a keydown handler to catch the arrow keys. When the focus is lost on an input, it is supposed to call the submit handler on the form. When I use the tab key, it works as expected, and calls my submit handler. However, when I use the arrow keys, it submits the form and goes to the action url, not running the alert in my custom submit handler. It's as if it either loses the bound submit handler or it calls a new default one or something.
I've come across an issue where I've got a dynamically created popup class that despite appearing to be bound according to Visual Event does not fire on clicking the closebutton attached to it. I'm not getting any errors in firebug and by setting breakpoints I've verified we are not reaching the code to execute. Ruling out the usual suspects such as obvious spelling mistakes/ swapping out jquery versions 1.3/1.4/1.5 doesn't make any difference.where else I can look?Here is the original function:
$this.find(".close").live('click', function() { var $this = $(this); $this.parents("." + sets.popupClass).remove();
The table, and the input id element, are dynamically created from database records and I use jQuery live to initialize the datepicker for each field, like so:
The idea is that when I click in the input field, the datepicker pops up and allows the user to input a date. While the date shows in the input field in the table, the value attribute of the input field is empty. I can't use the getDate() method on the datepicker, since I can't programmatically connect the datepicker element in any particular row with the input element in that row. I tried the onClose method shown below, but that doesn't work either. Has anyone done this successfully?
Using : jQuery Validate (jQuery Validation Plugin 1.8.0)
Browser : IE 8
Code :
Problem: The live('submit).. code fires before the validation does. So, validation never actually stops the form submitting. In other browsers (Firefox, Chrome, Safari), this is not a problem, validation always fires first.
I seem to be having trouble getting the submithandler form attribute working. The link is here: [URL]. For some reason it submits and does not show the alert I have inside the function of the submithandler attribute.
On the very next line I am attempting to bind a submit event handler to the form:
$('#loginform').submit(function() { $.post('member.php', $(this).serialize(), function(data, status) { data = eval('(' + data + ')'); if (data.msg) {
[Code].....
The form is loading fine, but for some reason the submit() is not getting attached to the form. Therefore when I submit it is running member.php from the form "action". Ultimately, I want to be able to run member.php from $.post() so that I can tell member.php that JavaScript is enabled.
I am trying to hide confidential data being submitted by a payment button. Now I am wondering how I could catch the according <form> element being created "on the fly" and submit it automatically ensuring that there is no chance for anybody to access the data.
I am trying to use the .live() jQuery function in cooperation with the .addClass() function, but I am unsure of how exactly to pass the parameter of the class-to-be-added's name through the live() function to work with addClass().Here is an example of the jQuery I would be using: [code]
I would like to use addClass() in both instances in the code above in cooperation with live() while being able to pass the class's name through the live() function. I've searched around the web quite a bit, but none of my searches have resulted in an answer that fits my specific needs.
function callFunction(param1, param2) { } this function is called when a user clicks on an image onClick='callFunction(1,2);' etc.
How do I apply live to callFunction? The image appears from an ajax call and as such the function doesn't recognise the call. I've used live on my other simple functions, but how would I use it on my custom function? The reason I am using the custom function is because I need to pass parameters to it.
I am having trouble figuring out how to correct this error, i think i have narrowed it down to what function is causing the issue, since once i comment it out, it doent give the error, but the code no longer does what its supposted to. Whats weird is that the code works how it should even with the error, but i dont want any errors even if they arnet effecting anything... well here is the code:
I am very new to jquery live function & i stuck in to the problem. I am using live function to get the ajax response & appending to the div here is my code,
function add_master(module_url, response_target_id, custom_id) { $('a.addclass').live('click', function() {alert('add'); $(response_target_id).fadeIn('fast');
again I turn this forum as the issue I have is beyond my current knowledge and I have found it impossible to find help on through google.First up, I have some code that puts a keyup event on all text boxes that have a certain string in their ID. That code uses 'live' and looks like this.$("td[id*='tdQuantity'] .field_input ").live('keyup', function() { calculateTotal(); });This one is simple enough. All the input boxes that match that selector call 'calculateTotal()' on keyup. I have code that adds a new dynamic row of items. Hence my use of 'live' above'. However, once it hits calculateTotal() I have it hard coded items on the first row. For example..
if (isNaN($('#tbQuantity_1').val())) { iQuantity = 1; $('#tbQuantity_1').val('1');
I am currently working on a project where I am using the jQuery Calculation plugin [URL] to do some math functions in a dynamic form, the issue is that when a new set of fields is created the calculation script only pulls data from the ones there when the page loaded, I am fairly certain that what I need to do is use the live function, however I am not very familiar with it and still learning. My jQuery for the plugin is : $("input[name^=emem]").sum("keyup", "#totalMem");
I need to know how to add an event to a button. The specific issue is that I want to add an event which is a prototype function of a class. Consider the following as an example:
I recently implemented the Image Cross Fade Transition [URL] add to the code to enhance the functionality. Currently, if I hover over the image, it runs the cross fade transition, which I would like to keep. I have another div on the page that I would like to trigger the first instance when hovered over as well. Is there a good way to add this? Here's what I'm using for the first instance:

I have to create a dynamic html block that can hide and show text, anchor tag is used to hide/show the block, which is also dynamically generated, so I have to call anchor's tag click event using live function, but within that click event I have to look up for immediate next div control which will hide/show. my code is somewhat like below I am comment the line of code which is not working
$("a").live("click", function(e) { var $nextElement = $(this).next("div");//div control is not found here, it is also dynamically generated. ($(this).html() == "[-]") ? $(this).html("[+]") : $(this).html("[-]");
It only breaks when located inside the click handler. It does not return response headers or a response. Is there something about event handlers and ajax that I'm missing?
