How can you make sure all javascript librarys imported into html have loaded

Hello Experts,

I am calling a google javascript function in my code:

var decodedPoints = google.maps.geometry.encoding.decodePath(encodedPoints) ;

However, earlier in my code, I call the library:
<script type="text/javascript" src="http://maps.google.com/maps/api/js?libraries=geometry&sensor=false"></script>

What appears to be happening is that if the library has fully downloaded then my line of javascript is erroring. Does anyone know how to put a test in there which forces the library to be loaded before the javascript can be called (or only call the javascript ones the library has loaded)?

Many Thanks

//Try waiting for the dom to be ready by enclosing your code in the following event handler:

  window.onload  = function() {
    var decodedPoints = google.maps.geometry.encoding.decodePath(encodedPoints) ;
  };

Hi,

Thanks for the replies.
Just to clarify that the decodedPoints... statement is part of a larger function which I am calling when users hit radio buttons on my site (this piece of codes draws lines on a map depicting a route).

Therefore would the following work or should the onload function only be called separately?

function xx()
{
 .
.
.
 window.onload  = function() {
    var decodedPoints = google.maps.geometry.encoding.decodePath(encodedPoints) ;
  };
.
.
.
}

Hi,
Please ignore my last point.
Also, the best solution is both answers (but I can only choose one - so I chose the first response).

Many Thanks
