Undefine Method

The Undefine method undefines a variable, object property, or value. Assume Siebel CRM defines a value, and then a defined method returns true for this value. If you use the Undefine method with this value, then the Is Defined method returns false. Undefining a value is not the same as setting a value to null.

The following example sets the n variable to 2, and then undefines the n variable:

var n = 2;
undefine(n);

This method is unique to Siebel eScript. For more information, see Make Sure the JavaScript Interpreter Can Run a Function.

Format

undefine(value)

Table 84 describes the arguments for the Undefine method.

Example

The following example creates an object named o, and then defines an o.one property. It then undefines this property but the o object remains defined:

var o = new Object;
o.one = 1;
undefine(o.one);
