JQuery :: Traverse The XML Properly Without Going Thru The Entire List?
Jan 28, 2011
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've been working with a little script from URL... but it doesn't seem to loop through the entire list.It works properly if I leave an empty list item in the UL - but that is not ideal.If i leave the count at 0, it leaves the final list item blank.
I am able to display the validation error messages at top of with wrapper: "li" like the following screen: But when I enter a valid email into E-mail field, the list item bullet not display (hide) properly in the error container, please see the screen below: Is this a bug or did I missed some settings in my source code?

I tried implementing a cleaner approach to a web form I had created, but it doesn't seem to be passing the values to the server properly. This form on the left and right work perfectly, but they have two ridiculously long drop down lists, which would be the "ProgramOfInterest" fields [URL] On this form, I tried creating a triple drop down list setup to clean up the older, long lists in this example, but it doesn't pass the values properly. It also seems to not duplicate the new drop down triple drop lists properly as in the original form. You can change the values in the drop downs in the forms to see what I mean. Also just pick Bachelor's > B_Business > Business Administration in the triple drop downs for an example since I don't know how to preselect those values.
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 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've got a quick question about jQuery's slideDown method. Unfortunately, I can't think of any sites that have this at the moment, but you know how some sites have a menu that has an entire div (or table) slide down when you hover over an element? And then you have the sites that slide down either the same thing or just a bunch of <li>'s? How can the effect of sliding down the entire div be achieved? The animation looks completely different from my site (which I will provide below). I will edit my post if I can remember the sites that have this, but for now, I can only provide my site which has the "rolling down" or "sliding down <li> tags" effect: [URL]
I'm looking for a way to disable an entire form until someone checks a check box. I would like it if the form is visible but has a "grayed out" look, and cannot be submitted.
So by default the form elements are all disabled. Once the checkbox is clicked the elements are enabled.
I am working on a mini select manipulation, moving options back and fourth, etc.
What are some of the considerations between passing just the ID names of the two selects from the button that triggers the add/remove versus passing the selects?
I was trying to modify the code-slider plugin so that it would scroll panels that were the size of the entire screen. (the demo on the jquery site has it moving panels that are rather small). So I thought all I had to do was take each div that sandwiches the panel (several are nested) and set their width in code to be the width of the monitor. It did not work.
So I simplified the code to show here. I just have the divs, and their css, and the code that sets them to the width of the screen.
Here's the entire code, css, and html (its not long):
We want the panel to extend the width of the page, and eventually also figure out how to make it extend the height of the page. Then we want to put a menu on top which will scroll from panel to panel, where each panel covers the entire page. The menu would have absolute positioning, so it would stay on top.
i want to load my entire front page with jquery, after a button is hit. Something like redirect to front-page.
I've already got the handler on the button, that executes document.location.href = '/index.php' Its working, but i'd like to make its behave like(pseudocode): $.ajax('/index.php') or: $.load('/index.php')
Is that possible, and if it is, how can i do that?
I want to be able to click in at table row, then it'll make the whole row editable, each cell from that row will have a text field; it will allow me to edit an entire row at once.I installed jEditable and it's working. I can edit ONE cell at a time. I just don't know how to edit an entire row at once.
I want to display an element underneath (zindex) the entire body.so I want to move the entire dom from the body node into an absolutediv (top/left 0/0) , then create a new div with that element withlower zindex and place it under the "body" div.how do I best do that with jquery?
