javascript syntax explanation required.

Hi all,

 

Im pretty much a noob to javascript. I try to get how the statements work together.

 

if you have a javascript command like this:

     document.all.myFile.innerText

Then document is an object and so is all

myFIle is a variable but what is innerText ?

Is that a property or a method?

 

Are there any obligations in writing these commands? like this: object.subobject.property.method?

 

Or are you free to use these through each other?

AFAIK, you have to start with a reference, and work your way down, level by level. For example for document you can find a list such as the one on this page...

document.all seems to be an obsolete Microsoft property.

Every object has properties. The properties may also be objects which have their own properties. There is a hierarchy, you have to know which objects have which properties.
