Re: [Dynapi-Help] Dynapi3 getContentWidth and Template

[Raymond I. <xw...@ya...>]

The problem is not with the inserting of the code it
is with access getContentWidth() before the page
loads.

Your code should access getConentWith() in this
manner:

dynapi.onLoad(init);
function init() {
  var newContentWidth =
sizeTemplate.getContentWidth();
}

Where the getContentWidth() function is called after
the page loads or during DynAPI's onload event.
