I have AJAX functionality on my page which creates anchor tags. I know I can fabricate a postback for these links by setting the href attribute to javascript:__doPostBack('ControlID','SomeArgument')
How do I execute server code based on this fake postback for 'controls' that are created on the client side?
You need to implement IPostBackEventHandler on your page.

Suppose i have an URL example.com, i want read the source of that page and get a particular link like example1.com and make a clickable event on it ,means that represents user had click the link from that URL example.com to example1.com.
You will need to first make an ajax call to that page to get the content to parse, then parse the webpage content with the link in your case example.com then go to the page (with or without click event).
Requesting Webpage
You will need some sort of ajax call to get the contents of the webpage for parsing.
See jQuery Ajax
Parsing
Get the #id or .class where the link you need is located (within the parsing function).
see jQuery Parsing
Redirecting
Click event isn't necessarly needed if you can just redirect to that link when you get it but this answer here has both information you need about click/redirecting with JS.
Good luck.
I am using an IFrame in my WebForm aspx page. I fill in the data in the IFrame, IFrame has the auto post when all data is filled.
I click the Server Side button that posts the page back to the server, I need to check a certain value in of the IFrame before I post back in the page.
I have added on client click javascript function to server side button to investigate if the value is populated for the element inside IFrame.
I get cross-origin error. Is there a way to check/wait for the iframe to populate the element inside it before I trigger my server side code ?
I'm trying to load a page on the same site and click a link. I can either use php or javascript. Is this possible.
One way i am getting to mind now is to send a paramater in the URL.
And the do a $_GET.If it is set to a particular value then do a
<script> document.getElementById("id").click(); </script>
I am trying to dynamically change the URL of a Facebook Send button with Javascript, but I have had no success so far.
I have a page set up with a few inputs, and I would like the URL of the send button to take the fields value as parameters before it sends it. The problem is when I add the send button to the page, it generates the iframe code inside and even if I modify the href parameter later on, the iframe still keeps the original link in. I guess the solution would be to refresh the content of the send button somehow or add it after page load, once the fields have been completed, but I couldn't figure it out.
Thanks for your help.
You can try using the iFrame version of the like button instead the XFBML version. The like button can be post-loaded into the page after the form submission, via an AJAX call, in which you have passed the data filled up in the form.
You can't do this. Javascript can't be used to control an iFrame on a different domain than yours. This is due to the Same Origin Policy.
What you can do is change the parameters on you send button xfbml tag and then call FB.XFBML.parse(); so the button uses the new parameters.
I am creating a project using ASP.NET MVC. I want to show content of pages in the placeholder without refreshing the page, something like ajax but WITH the URL changing, How can I accomplish this ?
Thank you for your responses
If you change the url of the browser this will automatically perform a redirect and refresh the entire page. You could use the hash sign (#) which doesn't trigger a refresh. For example if you change /home/index#foo to /home/index#bar the page won't refresh but you could send an AJAX request behind the scenes to update some placeholder.
I've used the jQuery BBQ plugin (http://benalman.com/projects/jquery-bbq-plugin/) with great success. This and the jQuery Templating engine would be great for what you are trying to accomplish.
