How to access querystring values from javascript after url rewriting?

  
Hi mates, I´m using ASP.NET 3.5 with C#. The problem that I have is the following. I´m using url rewriting (in the Global.asax file) and people see urls like this:http://localhost:1855/uk/london but after I rewrite the urls I work internally with querystring values and the urls become somehting like this:http://localhost:1855/post.aspx?co=1&ci=1In my Global.asax after I create the proper url with the querystring values I just apply it with the following sentence (this is an example):Context.RewritePath("/post.aspx?co=1&ci=1");The problem is that from javascript using the following function I access the first url and not the second:function getQueryVariable(variable) { var query = window.location.search.substring(1); var vars = query.split("&"); for (var i = 0; i < vars.length; i++) { var pair = vars[i].split("="); if (pair[0] == variable) { return pair[1]; } } } I need to access the querystring values because I need to load values in a textbox using jQuery.autocomplete and Web Services. Can anyone tell me how to access the rewritten url to get the querystring values?Thanks in advance mates

Find and compare values from a repating table?

  

Hi all

I am trying to loop through a repeating table, which is a secondary data source, and compare the Title column from the repeating table to another string which is not from the table. If they equal, I want all other rows to be hidden, except the equal one. I could do it easily in regular c#, but have not done it with InfoPath. I am not quite sure how to acheive that in InfoPath. If somebody could give me some sample code to put me in the right direction, I would be most thankful.

Regards.

ASP.NET, HTML, JavaScript Snippet Support (VS 2010 and .NET 4.0 Series)

  
This post covers another useful improvement in VS 2010 - HTML/ASP.NET/JavaScript snippet support. Snippets allow you to be more productive within source view by allowing you to create chunks of code and markup that you can quickly apply and use in your application with a minimum of character typing.

Visual Studio has supported the concept of "snippets" for VB and C# in previous releases - but not for HTML, ASP.NET markup and JavaScript. With VS 2010 we now support snippets for these content types as well.

call JavaScript - jQuery code from ASP.NET Server-Side

  
jQuery got so close to me lately that I can see myself adding the scripts to my project almost unconsciously. The thing is, jQuery is very useful for me, in almost all situations and it has been a do or die enhancement for all my project since I first put my hands on it.

Of course while using it, you encounter few situations which need a bit of research to solve, mostly when you are trying to combine it with some other technologies like: UpdatePanels and ASP.NET Ajax. For instance there are many situations when I would like to run some jQuery magic based on some decision that I make on the server side.
