Question

I’m working on a project which needs to use youtube api. The html and javascript works fine in different browsers. Yet When I just WPF’s webbrowser to run it, I get the following error:

Script Error
line:1
char:1
Error: Syntax Error
Code:0
URL about://:/

Do you want to continue running scripts on this page?
yes no

When I click yes, the message box went away and the program just works fine. I comment out most of the content on the html file and found that the following sentence caused this problem:

google.load("swfobject", "2.1");

So now, I just want to catch this error, just don’t want the messagebox to popup. I tried

try{
      google.load("swfobject", "2.1");
}catch(err)
 {alert("caught");}

Yet, I still get the initial error box. Is there anyway to remove the error box? Thank you very much.

You can’t actually use try/catch blocks to catch syntax errors. A syntax error means that the parser can’t correctly parse the JavaScript. Syntax errors happen before the code is ran.
