jquery - how do i access those arrays and variables in the dom?

Im using firebug to debug jquery and in the dom tab i can see all the vars and arrays in there.

How do I access the different arrays and vars in the dom?

I cannot access these object items, even though firefox lists them, i have sitems in the top level of the dom, i also have sitems within the parent variable.

a lot of head scratching happening here, would be grateful for any help :)

Looks like you want to access a user defined property, since these are not properties of the DOM ( Firebug Wiki DOM panel page. ), I don't think you can access them directly through your page, but you can access them through the Firebug console.

Simply type the name of the property into the command line of the Console... the part after >>> on the very bottom.

In your case you would type something like: sitems[0] and hit enter.

To access properties of the DOM... take a look at the DOM exploration page for Firebug.

To see how to access properties, functions, or constants of the DOM, check what you're interested in in the DOM tab.

Then you can "follow the bread crumbs" to access properties directly. Global properties are attached to window, so you don't need to include window:

Make sure to right click on things and explore the context menu, especially if you start looking at functions.

If it's an array you should access it as an array by referencing the index in the Array you are trying to access.

alert(sitems[1]); 

If it's an object you can reference by using the "key" for the property or method of the object you are trying to access:

alert(sitems["keyName"]);

Likewise some of the stuff you'll see in the DOM tab are actually references to methods and objects within the DOM, so if you're going to call them or reference them you need to do so based on their type, or you may even need to provide arguments to them in order to get a response.

It's giving 'undefined' because you can't output the contents of an Array just by calling its name.
