I am pretty new to jQuery, so apologies for such a basic question. But, it seems to me, the DOM is a hierarchical data set, and jQuery runs up and down this set in order render many of its results.I would like to understand, therefore, what method(s) jQuery uses to traverse the DOM. Is it using some form of indexing - a radix tree maybe?Developing the thought, I am wondering if there are any caching or optimisation steps I could take to help it along.I ask because a) I am always curious about these things b) I would like to write the best code I can based upon as much information as I can get and c) I am starting to use Ajax and, it seems to me, that the sequence and timing of asynchronous requests needs to be carefully thought through. If requests to the DOM can ever conflict (logically or otherwise) with requests to a server, I would like to understand how it all works.
I am new to jQuery.I have a problem where I want to traverse through DOM.For example a complete webpage.Is there any jQuery way to traverse complete DOM of the current page where the jQuery script resides ?
I would expect it to show "2" but instead it shows "0". Why?
It seems the find() method doesn't work on the newly created elements. Do traversing methods only work on elements that are actually in the document? If so, how can I traverse and manipulate freshly created elements prior to inserting them into the dom?
I'm getting some XML back from an ajax call ... it's working as expected.My problem/question is that I don't know how to traverse the XML properly using Jquery.This is what I'm getting back:
My code currently uses $(this).find("photos").each(function() to get each of the photos, and that works fine.However, the list of photos can be quite large, and I really don't need them all -I'd like to just "grab" the one or two photos I know I need based on the id and size attributes. Is this possible without going thru the entire list?
I have an iFrame on a page where I am calling .mouseup(function()) on it's document child.Once in the mouseup function, I need to refer to a specific sibling of the iFrame.Unfortunately, I cannot figure out how to traverse backwards to the iFrame element from $(this) - where $(this) is the document. I get a null set returned when I try$(this).parents().
There are a number of products. I'm just wondering how do I use "ProductName" as a product key to output its unique values?
Eg. the ProductName is "Chocolate Spread" - how do I output the "HowManyCalories" and "Product Image" only from the "Prods" array, based on the key "Chocolate Spread"?
Unfortunately, I couldn't find any way to traverse the object array in reverse order. I'd thought there must be a way to do it with for..in loop, but couldn't find anything yet.
I'm working on an image gallery at the moment and I'm having some trouble with the array the the images are stored in. The issue I'm having is that I can't figure out how to increase and decrease the current element in an array with the onclick event. Here's what I'm thinking so far:
var imageList = ['a','b','c','d','e']; var position=0; currentImage=imageList[position];
if a link with the id of "leftClick" is clicked, then position should decrease by 1 but if a link with the id of "rightClick" is clicked, then position should increase by 1 Both of these conditions should be bound to imageList.length i.e. if (position<0){position=0}; and if (position>imageList.length){position=imageList.length}; So how can I make "position" increase or decrease by clicking a link using the onclick event?
I am working on a project using the (brilliant) cycle plugin, here's the scenario: (apologies in advance for bad terminology that may be used)
I have a pager using thumbnail images, the slides contain text, at the moment cycle automatically cycles through the slides. I want each pager thumbnail that corresponds to it's respective slide to grow when active using the hoverpulse plugin.
I've been attempting to use 1.4.1 but I'm finding that $.get() and .getJSON() callbacks fail. The XHR requests succeed. I can examine the full request in both Chrome and Firebug. However, the callback functions *don't* execute. To test, I tried the same url with both 1.4.1, 1.3.2, and via a raw XMLHttpRequest(). The last 2 requests succeed, 1.4.1 fails. //v1.3.2 WORKS, fails in v1.4.1 $.get('/topic/api/template/list', function(data){
I'm was able to successfully use your plugin for firefox, safari, chrome. When the form submits the request with file upload, here is the html I send back to the browser (via Rails): <textarea>{'status': 'success', 'avatar_url': '<%=@user.avatar.url(:medium)%>'}
Here i am posting the request to a servlet.The call is going to the servlet.But i am not able to get the data (filename which i am sending ) in my servlet. How to access the param value in the servlet.
I'm trying to make a jquery powered login and register element within a webpage. The page won't read the value of the forms I want it to read. The page is here[URL].. u1241436/Messages/(login or register forms). I use the following code:
Sorry but I can't get the very first tutorial to work. I put the custom.js in a test_jr directory in htdocs. I also put the starterkit.html file in the same directory. I copied the contents of jquery-1.4.4.min.js into a jquery.js file also in the same directory. Then I did the custom.js page shown here:
I tried clicking on the [URL] and I get the starterkit.html page. If I click on the "some link" it doesn't do anything. What am I missing? There are syntax errors in my editor starting on the line with the asterisks* Why is there an error there? It looks like it closes the click function?
Iam using jquery.validate.js I have a forgot password page it has 2 input fields. 1. User name and 2. Email ID The user has to type any one of the field. How to validate this?
I have been having issues with the .html(), .append() and .prepend() functions. If I attempt the following [code] jQuery doesn't seem to register the click. Is this a known bug? Is there a way around this?
I didn't suspect that it will cause problems, but found that Skype plugin is pasting some JS code into ready page and it search for number which are telephone like. Unfortunately when it matches, it is pasting js code. When tab is changed and I'm returning to the same page tab content is pasted second time in this tab. When I'm doing that again it's pasted third time... It's only happening on tabs on which this toolbar found telephone number.
I have five div tags(jquery tabs) in my aspx page...Inside the seconddiv(tab) i have a button. onclick of that buttton the second div(tab)should be switched..instead of that the first tab is coming.. How cani switch the tab in code behind(Inside button onclick event)...
I have created a couple simple custom validators but this one isn't working. I have an input #eSig and two others #FirstName and #LastName. I need to add a rule that says the value of #FirstName must be contained in eSig, and one that is the same for #LastName.
We are using balupton's history.js to process normal (without files) forms and jquery.form.js for these with files.
So our code looks like that:
$this.find('form.formularz').submit(function(event){ var $this = $(this), url = $this.attr('action');
[Code]....
I thought maybe it's something wrong with iframe, but there are requests made to server. On server side, there is 499 error code for IE (it's internal nginx error code, it says that browser closed connection before nginx even sent anything) and 408 for Firefox.
I want to use the great jquery.validate plugin. I have just one question. There are fields which i have to check via ajax calls. I just want to check them if they were changed. I thought about one option that i bind the valid method to the onchange event. I would prefer to call the validations on submit.
