JQuery :: Getting The Index Of An Element With A Given Class?
Aug 11, 2010
I have a bunch of elements with multiple classes like this:
<div class="foo bar">
<div class="foo bar snafu">
<div class="foo bar">
I can get all these elements in an array like this:
$ (".foo,.bar")
My question is - is there an elegant way of getting the index (in this array) of the element that has the "snafu" class? Or should I just iterate through the array until I find the wanted element and then remember its index?
I have many small divs which have a particular class. so based on this class only i am getting the click event on them. now what I want is to get the index of one single div one which we clicked.. I am not remembering how to do it..
I am new to this discussion but hope you would post reply for my query and encourage me to keep in touch with this discussion. Well here is my problem. I have made an edit in place form in which we can add and remove the elements. I have used jquery.jeditable.mini.js and jquery.duplicate-remove.js plugins for edit in place and add and remove action. I have live() function to access the dynamically ganerated elements like this. $(".addressDiv span").live("mouseover", function(){ clickable function here...
I'm trying to get the index of a div when its the same mark up for each set. I want to return index of '1' when a second "yo" is clicked in any "a" and '0' if the first "yo" is clicked in any "a". If i clicked the "yo" which has the color #330000, then i should get 1 not 5. This seems like a simple task but i cannot get it to work.
I have a calendar in which each day is a separate div, and all these are within a container div #cal. When a user mouses over one of the days, I want to figure out the index number of that day's div within #cal. Simplified example:
I can easily get the index of #nov2 from Firebug if I do this in the console: $('#cal div').index($('#nov2')
But, I can't figure out how to write a function so that I don't need to assign an id to each day div. I'd like to be able to just take "this" from the moused-over div, and pass that to a function that can turn it into the needed index.
I'm trying to find the currently clicked index of .accordion_trigger from within another element.
When inside the .accordion_trigger click event I can simply do the below to get the current clicked index:
Code: $('.accordion_trigger').click(function(){ var index = $('.accordion_trigger').index(this); } return false; });
Obviously this doesn't work when called from within another element. I understand that 'this' is part of the problem but can't seem to find a way to form the code in such a way for it to produce a valid result. Thus far I only get -1 or 0.
When .accordion_trigger is clicked it has an "$(this).toggleClass('active').next().slideDown();" applied so in theory I shold be able to search for which of the .accordion_trigger's are "active".
I've also tried doing this via the below method but to no avail:
Code: var current = $('.accordion_trigger'); current.each(function() { if ($(this).hasClass('active')) {
I'm trying to determine a better method of finding the index value of a form element. I need to find it because the JavaScript validation class has a function for validating a single form element, but it requires that the index number of the element in the form be passed in.Currently I am accomplishing this by a function that I wrote which I call for each field I want to validate:
function getIndex(element) { for (var i=0; i<document.thisForm.elements.length; i++)
i need to know weather or not there is a way to put the cursor below (z-index wise) a div element or make it so that you can click through the div element.
I'm using the jquery topZIndex plugin in my application. It's working great. Now I have a situation though, where I would like to return the element with the highest z-index on the page. The plugin has a function that will return the highest z-index, but it's a value, not an object.
I have an array "arr" that is an array of objects. Each object has the same 7 properties.I want to find the index of the object with a property that matches a certain value x in the array arr. The array has hash tables associated with it.
arr [ obj [ i ] . property1 + "_" + obj [ i ] . property2 ] = arr [ i ] ;
so whats the index of the object where .property1 = x ?

I want to get index number of form element array. where I want to put name in the front of code input box. Can any body tell me that how is possible.My code is as follow:
PHP Code:
<?php echo "<form name="region">"; for ($i=1;$i<=5;$i++){ echo '<input type="text" name="code[]"Â Â onkeyDown="check(this)">
I'm relatively experienced with jQuery (not a guru but not a newbie) but am wondering how I can write a script where if one element is hovered over then a different element on the page has a particular class added to it.
hi everybody, didn't find this using the search :( this is my problem: i create a dom element dynamically (<span>) and want to assign a class attribute to it such that it has some css style, this works in ie, but not in firefox :( here's the simple code:
<div id="somediv"></div>
var div = window.document.getElementById("somediv"); var span = window.document.createElement("span"); span.innerHTML = "span"; span.attributes.getNamedItem("class").nodeValue = "span_class"; div.appendChild(span);
so this works well in ie6, but firefox gives this error: Error: span.attributes.getNamedItem("class") has no properties
if i run this code on a statically defined span (in the html file), where a class attribute already is set:
changing the class to "span_class" works both in ie and firefox.
how can i fix my above code such that it works in both browsers? it seems that on newly created dom elements the class attribute isn't even there (to change it), how can i create it, and then change it?
I know that within the function I can access properties of the field (e.g. theField.name and theField.value). But how do I access theField's index number in the form's elements[] array -- from the "this" reference that was passed to the function? I.E. if this field is elements[3], how can I get at that 3?
I am trying to access an element in a page using ID using jquery in when the document is ready.But the problem is the length is always 0 even if the script tag is in the head or right at the bottom of the page. The element is seen rendered when I see it using FireBug.an someone point out where I am making a mistake accessing the element
