Question on string replacement

[ericazhj]

Hi,

In fact I am not sure if the title is proper. I will give you an example on my question:

Originally:

this.ajaxFunction();

I want to use:

var func_name="ajaxFunction()" ;

Then I want to call ajaxFunction() by use of the variable func_name. How could I do? I am new for Javascript. Is there some experts help me about it? Thanks.

You could assign the variable to contain the actual function itself. For example:

var func_name=ajaxFunction;

Note, no quotes, and no ().

Here's an example:

function ajaxFunction() { 
 alert("hello"); 
} 
var func_name=ajaxFunction; 
func_name(); 

Alternatively, you could use the eval function to evaluate the string into JavaScript code. For example:

function ajaxFunction() { 
 alert("hello"); 
} 
var func_name="ajaxFunction()"; 
eval(func_name); 

This method is slightly more costly though.
