getObj( id )

This function returns a reference to the object with the specified id on the screen.

This function call is equivalent to the native JavaScript syntax:

document.getElementById(id);

Parameters:

id – element identifier – String;

Example:

A reference to a textbox object on the screen can be returned by writing this line of code:

var textbox = getObj('I_5_10');

After a reference is obtained, the object’s methods and property can be accessed through native JavaScript. For example:

textbox.style.backgroundColor = 'yellow';   // highlight textbox
textbox.value = '';                         // clear textbox*
textbox.focus();                            // place cursor within textbox
