javascript jquery url part trimming

I have a url like

http://www.blah.com/something/maybesomethingelse/Webservices/something.asmx/blah

That is being passed through a jquery ajax request.

I want to remove everything after /Webservices/ so I can stick a new page in for error ha开发者_Python百科ndling.

so ideally this would return

http://www.blah.com/something/maybesomethingelse/Webservices/

Then i could just concat on the new page.

Thanks for your help :)

Simple way: url = url.split(/\/Webservices\/)[0]+"/Webservices/"+yourstuff

or neater

var lastFolder = "/Webservices/";
url = url.split(lastFolder)[0]+lastFolder+yourstuff;

You could use a parser like this one:

but in this simple case, you only need to find the last index of "/Webservices/":

var lastIndex = url.lastIndexOf('/Webservices/')

and then take everything from the beginning up to the end of "/Webservices/":

var baseUrl = url.substring(0, lastIndex + 12)

and then append the new page:

var newUrl = baseUrl + '/Error.aspx'
