Application Examples of the js setTimeout Function

The window. setTimeout method is used to delay the execution of a function (method. However, it is defective when calling the specified method and passing parameters.

Infinite Loop

The Code is as follows:
<Div id = "num"> </div> <Script type = "text/javascript"> Window. onload = function () { Var a = 0; Function addNumber () { A = a + 1; Document. getElementById ("num"). innerHTML =; Settime out (addNumber, 1000 ); } AddNumber (); } </Script>

The setTimeout function can pass parameters/values.

The Code is as follows:
Var _ st = window. setTimeout; // FRef is the test function, and mDelay is the time Window. setTimeout = function (fRef, mDelay ){ If (typeof fRef = 'function '){ Var argu = Array. prototype. slice. call (arguments, 2 ); Var f = ( Function (){ 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 be executed, the second parameter is the interval, and the following parameter is the value to be passed in.

The Code is as follows:
Window. setTimeout (test, 1000, document. getElementById ("d"), 'abc', '123 ');
