JQuery :: Accessing An Element Using ID And Class?
Dec 5, 2011
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
So I create a class: function cMap(mapID){//vars and stuff}
I go and prototype a function: cMap.prototype.loadMap = function(){ //jquery AJAX call }
Now in the jquery $.ajax({...}); call, I use an anonymous function on the "success:" call: success: function(data){ this.member = data; }
My problem is that inside this anonymous function call I'm trying to call a class member of my cMap class to store the data in from the AJAX call, but it's out of scope. So the JS console in FF/Chrome throws errors about bad value/doesn't exist.
How can I access this class member from inside an anonymous function? Or at least what's a good way to go about doing all this?
Basically I want to recognize which <div> tag was double clicked, and hide the corresponding link that is nested within that specific <div> tag.
The only way I can think to do this currently is to basically copy and paste a whole bunch of jQuery code for each <div> tag and it's sub-elements (links in this case).
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...
In a project repeated blocks are identified by an <input type="hidden" value="x" /> field. To get an access to one of the block I wanted first access to that field. My first problem is there and I will explain it by a micro-project (tested with Firefox only)
Here is the HTML code : <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "[URL]"> <html><head> <meta http-equiv="Content-Type" content="text/html; charset=utf8" /> <meta http-equiv="Content-Style-Type" content="text/css" /> <meta http-equiv="Content-Script-Type" content="text/javascript" /> <link rel="stylesheet" href = "index.css" type="text/css" /> <script type="text/javascript" src='Library/jquery-1.4.js'></script> <script type="text/javascript" src='index.js'></script> .....
And here the javascript code wher is the JQuery question //meta http-equiv content-type charset=utf8 function test(){ var $id = $('#curUnion').val(); var $objet = $('#toutesUnions > .pseudoFieldset').find('input[value=$id]'); var $test = $objet.val(); var $objet2 = $('#toutesUnions > .pseudoFieldset').find('input[value="1"]'); .....
With $id = "1" as shown by the Javascript debugger (in Firefox) where is the difference between find('input[value=$id]') and find('input[value="1"]') Giving the alert result => undefined / 1 If you want to test the micro project you will find it in the Test.zip joined. How to access the immediate parent pseudoFieldset to get its html code?
and i want to access the element dropSubPrd that is inserted on that ajax function, on the div FirstResult, but it will not work in $('document').ready because when the page load's that element isnt there.
Bit of a problem I've not been able to solve after a couple hours. I'm new to Javascript classes and objects and really a Perl programmer so this has been giving me a headache. I've attached the code below but in a nutshell I have an object that writes code to a div upon instantiation and attaches events to several controls. When the event fires it runs a function attached to the class via prototype.
Problem is, the "this" obj from this event now refers to the control (e.g button) so there is no way to get back to the class. If you look at " alert(this);" line this should output the Class object, instead it refers to the button
When retrieving JSON data I'm able to access individual elements using the $.each() function and iterate over them. However, how would I access just one element by its location and not by name? (i.e. data(0) not data.ID).
I am echoing some dynamic content into a DIV based on form entries. The content is essentially a dynamic table, with results populated based on the user input. The user can further refine the database results by entering more data into other fields. All of this works fine. What I'd like to add is the ability to click on an <a> tag header on each column to sort by that column. I haven't gotten it to work, so I wanted to try a more simple test. I currently echo <a id='test' href='#'>Click Me</a> into the DIV set aside for AJAX response. I then setup a jquery .click() event monitor to simply alert me when I click on it. If I place this <a> tag in the main portion of the content that is static, I get the alert box. But when I put this into the content of the DIV tag generated dynamically by AJAX, it doesn't fire the alert. Is there something I need to do to 'reload' the page? Is the dynamically added content not part of the document since the entire page isn't reloaded?
I have an object on the document element that allows for other components to register with it, i have a custom event something along$(document).bind("register",function(thechild)..So in the child object when they are created i call$(document).trigger("register",this);And indeed i get the DOM object. However i'm looking for the plug in object, i want to be able to call methods on the passed childobject and access it's Config.Does that make sense? How can i write a plug in that is applied to various objects that also registers itself with an 'overseer' object on the document element in such a way that i can allow that overseer object to call methods on any registered child objects?
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.
I have been scratching my head on this one for a couple days:
Code: function hideAll(){ var education = document.getElementById("education").childNodes;
[Code]....
As far as I know, this should be working the way I expect it to (set the display of all the childnodes to none), but I guess I'm missing something. Is it not possible to instantiate a variable using childNodes without choosing a specific index of the array? I just assumed it would work like any other array
i am creating text box Elements using DOM if only user needs it by using Create Element
var element = document.createElement("input"); element.setAttribute("type", "Textbox"); element.setAttribute("name", "group[]"); newdiv.appendChild(element);
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 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?
Is there a non-structure specific way of finding the next element with a given class? for example you have a structure of:
When you click on the link in container1 the expected behavior is to change the css on a1 in container2 but not in container1 or container3. I have tried playing with parent, next and filter without success. this is the best I have is:
I have table that has four columns and many many rows. It is quite long. I need to add a special divider (border) between each td cell. I thought I could create a css style .border_right and apply it to all td cells using jquery addClass() and then remove the class from the fourth td cell in each row so it does not add to or affect the outside border of the table.
My question is, how do I remove the class from the fourth td of each row using jQuery? I figure there has to be a shortcut way (one or two lines) to do this using jQuery so I don't have to manually add a 'class="border-right"' to each td I need it on.
