In another topic this iframe script was mentioned: http://www.phpmix.org/iframe_height_auto_resize/iframe_height_auto_resize_the_code

Some of its syntax looks unfamiliar to me. What is it called, and could someone explain it?

Example 1:

CODE

var DYNIFS = {
    // Storage for known IFrames.
    iframes: {},
    // Here we save any previously installed onresize handler.
    oldresize: null,

    ...etc

Example 2:

CODE

onresize: function() {
...etc

DYNIFS is an object, and this is an "object literal" - in other words you're just building the object from constant values. Try Chapter 8 of the Flanagan book if you have it.

Example 2:

CODE

onresize: function() {
...etc

Oh, well I suppose this is within another object declaration, where one property of the object is a function.

OOPS! (Sorry, don't know the smilies very well, so here's a random selection...
