The standard syntax of setTimeout is: setTimeout (expression, time (MS.

Note the call of the first parameter as a function. Assume It is a function.

1. The function has no parameters:
Function alertV () {alert ("000 ");}

When the first parameter is not enclosed by quotation marks ("" or ''), the delay is one second:
SetTimeout (alertV, 1000 );

When the first parameter is enclosed by quotation marks, the delay is one second:
SetTimeout ("alertvs ()", 1000 );


2. function parameters:

Function alertV (event) {alert ("keyCode =" + event. keyCode );}

Set this parameter:
SetTimeout (function () {alertV (event) ;}, 1000); otherwise, the system will prompt that the parameter is not defined.

If anyone has a good method, thank you for sharing it.
