Question

jQuery, string manipulation : find a tag

Answer 1

+4 A:

In short, I don't think you can. jQuery only allows you to select tags that can be placed within a div tag. Your title tag doesn't qualify.

See this answer for more information.

Other options...

Partial HTML:
There are other options. You could return partial HTML whenever you experience an error. Instead of <html><body><p>Error</p></body></html> you return <p>Error</p>.

JSON:
You could also go with something a bit cleaner, like JSON. Since you're working with ajax anything, you could send back the following string:

{'status':'failed','message':'Something bad happened'}

And then access the 'message' value within your client-side script.

Proxy Script:
By using a proxy script written in either C# or PHP you can get access to the value of a title field, and return that to your jQuery ajax process.

IFrame Method:
Load the results up in an iframe, and then get the value through iframe.document.title. You can make your iframe 1x1, so it's not visible.

Other client side solution maybe ?

Go with a different type of data. Send JSON back instead.

Jonathan Sampson that's will work with this sent code (in the answer) ? http://stackoverflow.com/questions/1170230/asp-net-mvc-with-jquery-catch-exception-display-error-message

@Jonathan Sampson : I don't decide what I return. In the ASP.NET MVC I throw an exception like this : throw new Exception("MyMesssage"); the only think I want it's the this message only to display

Look at my last suggestion, concerning the iframe.

@Jonathan Sampson : not visible (1x1) and tried (display:none) but in both cases, the page behavior change :(

@Jonathan Sampson and the others :http://stackoverflow.com/questions/1034881/what-is-the-best-practice-for-parsing-remote-content-with-jquery/1049430#1049430This solution works fine. It's not very "clean" but workThanks for your time
