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;
  }
}
