Use of JS SetTimeout ()

First, the grammar

SetTimeout (CODE,MILLISEC)

Code: is a string that contains JavaScript statements. This statement may be such as "alert (' 5 seconds! ')", or a call to a function, such as alertmsg ().

millisec: Indicates the number of milliseconds after which the first parameter is executed.

Second, SetTimeout (CODE,MILLISEC) The use of code containing formal parameters

For example

var msg= ‘dfdsf‘ ;

SetTimeout (Alert (msg),+); // alert (msg) will be executed immediately

SetTimeout ("Alert (msg)",+); // System Error

The workaround is to use the anonymous function callback

var msg= ' fewweeeee ';

SetTimeout (function () {alert (msg);},1000);
