DOM access

Postby ruturajv » Wed Nov 16, 2005 11:37 pm

this is a strange requirement, I don't really know how to grab it from DOM,

there is a page that I own pageA where I call js code from other website
pageA
Code: Select all
....
<script src="http://somesite.com/code.js" type="text/javascript"></script>
...
// I want to put some code here...


http://somesite.com/code.js
Code: Select all
function abcd (xyz) {
}


now I want to put some code in PageA
which can find if the function abcd is defined or not

something like
Code: Select all
if (window.abcd) {
   //found
} else {
   //not found
}


but this doesn't work...

Any DOM masters around ???

how about something like this?

Code: Select all
function function_exists(func)
{
  if (window.func && (typeof window.func=="function"))
  {
    return true;
  }
  else
  {
    return false;
  }
}
