The Window.settimeout method is used to delay the execution of a segment function (method). But it is in a certain defect when calling the specified method and passing the parameter.

Infinite loop

The code is as follows

<div id= "num" ></div>

<script type= "Text/javascript" >
Window.onload=function A ()
var a=0;
function Addnumber ()
document.getElementById ("num"). Innerhtml=a;
SetTimeout (addnumber,1000);
Addnumber ();

The settimeout function can be used to pass a parameter/value

  code is as follows &nbs P;
var _st = window.settimeout;
//fref is the test function, Mdelay is time
Window.s Ettimeout = function (Fref, mdelay) { 
   if (typeof fref = = ' function ') {  
  & nbsp;    var Argu = (arguments,2);  
        var f = (
            function () { 
& nbsp;               fRef.apply (null, ARGU) ;  
        return _st (f, mdelay);  
    return _st (Fref,mdelay);
Function Test (x,y,z) { 
    alert (x+   +y+ "+z);

The first parameter is the function to execute, the second argument is the interval, and the subsequent argument is the value to pass in

The code is as follows

Window.settimeout (Test,1000,document.getelementbyid ("D"), ' abc ', ' 123 ');
