. I give a url (say google.com) in the first text box,
. Now when i click submit button the page(JS) should fetch google.com in the background and show some info(say all links).
Is there any way to get this done
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.

Can jquery be used to read/traverse a xml file?
View 2 Replies View RelatedConsider the following snippet of [code]...
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:
<media>
<photos>
<photo id="1" size="s">url/photo1-s.jpg</photo>[code]....
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().

View 5 Replies View RelatedI have an array called "Prods". Here are the different values in that array:
ProductName, HowManyCalories, ProductImage, LinkFromImage, Description, Price, BuyLink
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.
If I have the following in my document
<DIV id="leftdiv">
<DIV id="innerDiv1">

How would I get a reference to the input1 element using "getElementById"?

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?
It launches in IE and give the user instructions, then at the click of a button, launches my setup.exe. I want my webpage to launch setup.exe then go to another webpage on my CD, congratulations.html, which says "installation is complete etc". Here's what I am trying to do through JAvascript. It doesn't work. Should the first instruction be flushed in order for the 2nd one to work?

I want to use the values of text boxes on my HTML webpage to create a webpage URL (like below):
<script type="text/javascript">
My text boxes are as follows:
Now this all works and the result webpage URL prints to id='ID1', but the big question is how do I use this resulting URL in another Javascript section as the src="?
For example:
I am trying to display a webpage from another domain and tried to access its elements and I am facing issues with this.
I tried using "iframes" and am facing cross domain issues.
All that I want to do is, set and get the attributes of the elements of the webpage from the other domain (eg: set text field value, get dropdown box values, click button etc)
Is there a way to get this job done?
I thought of browser addons however it will be a browser specific solution.

I was wondering if there was an event thrown after the twitter items are generated on the page. There is an example here. I cannot seem to get the li items to change after they are loaded. I have tried using .ajaxComplete, but it doesn't seem to be working. Does anyone know what events are thrown after the above code, and that doesn't need user input? You could you alter the above code and fork your own version. For ideas on examples that could be created; you could change all spaces to periods or periods to exclamation marks.
