| The code is as follows |
Copy Code |
| callback function 1
function Callback (A,B,C)
{
alert (A+B+C);
}
callback function 2
function Callback2 (a,b)
{
alert (A+B);
}
This method does some action, and then calls the callback function
function DoCallback (Fn,args)
{
Fn.apply (this, args);
}
function test ()
{
Dynamically calling methods, and passing parameters
DoCallback (callback2,[' A ', ' B ']);
DoCallback (callback,[' A ', ' B ', ' C ']);
}
|
Note that the above Callback2 and the like can not be a string of OH.
What if you want to implement a dynamic call based on a string?

Use eval ("Callback2") just fine Oh, kiss is not very simple ~
