After a post with "$.ajax()", I sometimes receive an exception from the server. You can see a part of the returned HTML below:
<html>
<head>
<title>MyMessage</title>
<style>
/* ... */
</style>
</head>
<body bgcolor="white">
<span>
<H1>Server Error in '/' Application.<hr width=100% size=1 color=silver></H1>
<h2> <i>MyMessage</i> </h2>
</span>
<b> Exception Details: </b>System.Exception: MyMessage<br><br>
<!-- ... -->
[Exception: MyMessage]
lambda_method(ExecutionScope , ControllerBase , Object[] ) +159
...
</body>
</html>
I'd like to get the value of the title tag ("MyMessage") How can I do this with jQuery?
-
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 throughiframe.document.title. You can make your iframe 1x1, so it's not visible.Kris-I : Other client side solution maybe ?Jonathan Sampson : Go with a different type of data. Send JSON back instead.Kris-I : 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-messageKris-I : @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 displayJonathan Sampson : Look at my last suggestion, concerning the iframe.Kris-I : @Jonathan Sampson : not visible (1x1) and tried (display:none) but in both cases, the page behavior change :(Kris-I : @Jonathan Sampson and the others : http://stackoverflow.com/questions/1034881/what-is-the-best-practice-for-parsing-remote-content-with-jquery/1049430#1049430 This solution works fine. It's not very "clean" but work Thanks for your timeKris-I : Well doesn't work with IE :(
