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.

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 ?
We are a having search page(jsp) in our Liferay portlet which contains approximately 30 fields. When a person selects some parameter and press submit button then the action method is called and result are shown on the different jsp page. Which is the default behavior.
What we want to implement is that when a person submits the search form then the page must be ajax refreshed on the basis of those parameters.
What our understanding is that we can append the parameters in the URL and make the ajax call.Like in gmail if you do advanced search then the parameters are appended on the URL.
we can appended parameters into url so that when a user pastes url on the browser directly then a action method is called, jsp is loaded and then a java-script will read the parameters from the URL and fetch the proper data.
According to us the problem that we would be facing will be saving of the history in the browser so that whenever the page is changed due to ajax call and user clicks on the browser back button then the previous HTML state should be saved.
Is the above approach correct?
What could be the further issues that we can face while implementing the same?
How can we save the history so as to preserve the previous state?
This can be done by using the BBQ plugin. The BBQ plugin works on the hash tag change of the URL.

I have my own website. There is a link on my website which redirect me to the externel website. I want to know how to set value in textbox in that externel website when user click link on my website
Have you tried to save opened window handler?
var openedWindow = window.open(....
Instead of using direct links.
Or maybe pass parameters through url?
you can add parameters on the URL.
just modify the link accordingly, and read the URL parameter on the other site.
(this assumes you don't care the possibility that someone fills the parameters with fake info)
Unless that site has implemented something to let you set that (e.g. if they populate the text field using data from the query string), you can't.
There is no standard mechanism for pre-populating forms via a link to the page containing the form.
This is for a custom Editform.aspx being used to submit data to a custom list. Once the user completes the form, he should be able to hit a button or even the OK button, and have sharepoint submit the form data to the list, then redirect to the items Display form (dispform.aspx?ID='itemid').
I was able to get the ID of the current item by manipulating document.location.href. I tried to do a postback in javascript using __doPostBack with __commit and __redirect (redirecting to the URL displayform?ID='itemid'), but when the redirect happens, I see that the changes were not updated!
Anyone able to do something like this?
You can get the form to redirect to any location after it's been posted by modifying the URL in the Source querystring parameter. Using javascript, you could look for a specific URL (/location/dispform.asp?ID=) in that querystring parameter and if it doesn't exist, redirect the page to itself, but with the Source parameter filled out to the location w/ ID that you want to send them to.
The hardest part will be parsing the current URL + parameters in javascript. There's some snippets of JS code I've found that make it a lot easier.
One of the bonuses of rewriting the EditForm URL this way is that the Cancel button will send the user to the DispForm page instead of where they originally came from, although most people probably use the back button.
This lead me to solve my problem of a Form Action on my DispForm that would not take the list item ID to the custom EditForm. The following ended up working for me:
onclick="javascript: {ddwrt:GenFireServerEvent(concat('__redirect={ProgEditForm.aspx?ID=+',$ListItemId,'}'))}"
Where I have a DispForm parameter for ListItemID with
Parameter Source: Query String
Query String Variable: ID
Default Value: 0
Hope that helps someone else as this was near driving me crazy!
