Function Object (Windows Scripting - JScript)
Creates a new function.
Syntax
function functionName([argname1 [, ...[, argnameN]]]){
body}
Syntax
functionName = new Function( [argname1, [... argnameN,]] body );
Arguments
functionName
Required. The name of the newly created functionargname1...argnameN
Optional. A list of arguments the function accepts.body
Optional. A string that contains the block of JScript code to be executed when the function is called.
Remarks
The function is a basic data type in JScript. Syntax 1 creates a function value that JScript converts into a Function object when necessary. JScript converts Function objects created by Syntax 2 into function values at the time the function is called.
Syntax 1 is the standard way to create new functions in JScript. Syntax 2 is an alternative form used to create function objects explicitly.
For example, to create a function that adds the two arguments passed to it, you can do it in either of two ways:
Example 1
function add(x, y)
{
return(x + y); //Perform addition and return results.
}
Example 2
var add = new Function("x", "y", "return(x+y)");
In either case, you call the function with a line of code similar to the following:
add(2, 3);
Note
When calling a function, ensure that you always include the parentheses and any required arguments. Calling a function without parentheses causes the text of the function to be returned instead of the results of the function.
