i got an ajax script that appends a new form as the user perform some actions.then i bind them to the 'submit' event. the problem is that the existing forms get bound again and now submit twice, while the newly appended forms submit once.
is there a function to check if that form has already been bound, so that i won't bind it again? in the docs there's a unbind(). But will it slow down if i append more and more forms?
I create buttons from an array of objects that such as:
buttons = [{ text: "button 1", action: 1}, {text: "button 2", action: 2}];
I then loop thru the array to assign the text and bind the click event after having created the buttons with IDs of "button_<index>".
for( var index in buttons ) {
$("#button_"+index).html ( buttons[index].text )
.click( function() { clickButton( buttons[index].action ) } );
}
The text appears correctly in the button, but every button defined only fires the list bound click, in this example the action equal to'2'whether I push "Button 1" or "Button 2".My actual case has four buttons, all firing the event for the fourth button.I've tried not chaining the .click(), going thru the loop twice once for the .html and once for the .click, neither of which made a difference. If I hard code each button .click, it works fine.
THE QUESTION: How do I get a reference to my Object when processing an
event handler bound to an html element ?
CONTEXT:
Sorry if it is a bit long.
I am developing a JS calendar tool. One of the requirements is that the
calendar will need to display a varying number of months (1..3)
depending on the calling page. Imagine 1, 2 or 3 calendar pages side by
side as required.
I have built a grid object that will contain one month's dates with the
day names at the top. The calendar object inherits the grid object as an
array of "calendar pages" - one grid per month and the calendar provides
the content for each grid. I will use the grid object for another
completely different object later and so I want to use good OOP
encapsulation. The grid is a table generated on the fly and is "dumb" as
far as what it is used for.
I have attached an onlick event to each cell of the grid. Using OOP
priciples I want the calling program (the calendar object in this case)
to provide a function to handle the click and the grid object will
provide to the calendar the row and column of that cell as well as the
grid number (so the calendar can work out which date was clicked since
it knows what the data means and the grid doesnt). Code:
I though I'd give these forums a shot. I'm having trouble figuring out how to accomplish something and was hoping someone could help. I currently have the 'enter' key bound to a submit event on several on my pages, as follows.$(document).bind('keydown','return',function(){ $("#searchSearchButton").click(); });It works well, with one problem. I've written over the alert function with my own custom alert. When the alert pops up, I try to hit 'enter' to close the alert and nothing happens because the enter key is bound to something else.
I've found that if I unbind the enter key and rebind it to close my alert box, that works fine, but I can't figure out how, after the alert box is closed, to rebind it to the previous value. I'd have to grab the existing bind value before rebinding it to close the alert box, then replace that value afterward, but I have no clue how to grab the bind key's value.
I'm using Validation plugin from [URL]
I'm trying to implement a validation in my form, but that should not be bound to an specific field. in fact, I have three input type=text, and I need at least one of them to be filled (like a conditional 'required').
I could create a new validation method, like:
$.validator.addMethod("foo", function(value) {
// short version:
return field1.value + field2.value + field3.value != "";
}, 'required');

I'm trying to use some custom events but I don't know how to check if a custom event has already been sent.
I have a script "startup.js", which do some stuff then triggers a custom event "jobDone" on the body element (only one time) :
startup.js :
$(function() {
// do some stuff
$('body').trigger('jobDone');
});

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();

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.

The problem is this code is on a page that is loaded via post and if you go off the page and then back onto it jquery seems to attach the function again so it runs twice. So need to unbind this function before the script runs again.

View 1 Replies View RelatedEvent Listener. From what I understand it will check all events until a defined event happens, such as rollover of a certain image, and then it activates a function? What I want to do is use this so that when I rollover a element such as below:
<img src="img url" alt="this is a tooltip" tooltip="true" />
I want it to pass the obj to a function which then runs, and then once the mouse of not over that element it will activate another function passing the previous object to this function.
Although an element such as the example below would not activate these functions:
<img src="img url" alt="this is a tooltip"/>
As the tooltip tag does not exist or has the value of false. Also, wouldn't this use a lot of resources as it checks every event which the mouse passes over?

I have problem with event listening in CKEditor. I searched these forums for answer, but I didnt found it.
I need someting like "onkeypress" on textarea for CKEditor. If I think well, I can must use "DOM" of CKEditor, because it is not simple textarea - but I am lost here. I really dont know how to do it. I need simple draft saver - onkeypress will launch a function which will check if timer is on. If yes, return false. If no, use ajax to save content of textarea.
Here is the HTML: [URL] I'm trying to uncheck the selected radio button, then set the value to 1 (Yes), basically overwriting theinitialvalue to 1. I've looked at prop(), val(), and attr(), and just don't know where to start. Should I select $('#set_q157 input') or$('#set_q157 input:radio'), or each individual radio?
Do I need to each them, and check if its checked, then change its value, or is there a way to select all three inputs as just one radial button? It would also need to work if the input has not yet been checked.
I want a function that when you check on a check box another check box appears.
View 10 Replies View Relatedi have a list of checkboxes, the number of checkboxes is dynamic. All the checkboxes have same name. i am trying to get the length of selected checkboxes.

when i try to get the length in javascript like document.form.name1.length, it works fine if number of checkboxes selected are more than 1, but not for 1.

I have an .asp page for my customers which does just accepts e-mail information and passes this information to another .asp page. But before passing the info, a javascript checks whether the entered e-mail does match some certain rules. Rule1: If any input has been made at all, Rule2: If an "@" sign is there, if the"." is there and so on. upon pressing the submit button, the first rule works but the second rule does not. Could not figure it out why.
[Code]...
It is the function control() which validates the e-mail field. But it just validates whether the e-mail has been entered or not. The second check (with the @ sign) is not being made.
I got this problem with live() event.I have used it as follows.
$(".addressDiv span").live("mouseover", function(){
//clickable function here......
------------------------
});
I have used the live() event to trigger the function on mouseover in the dynamically added elements. But the problem i got is that once the live event is called it takes the class of the element and stores. And when the class of that particular element is changed dynamically the live() event does not detect the new classed added dynamically, instead it takes the former class. Live() event does not update the class.
