setTimeout()使用-白红宇

Basic setTimeout() Example

setTimeout(function() {      // Do something after 5 seconds}, 5000);

Tip: you can use the ClearTimeout() function to clear any timer values previously stored.

timeout = setTimeout('timeout_trigger()', 3000);clearTimeout(timeout);

More setTimeout() Examples

jQuery(document).ready(function () {    //hide a div after 3 seconds    setTimeout( "jQuery('#div').hide();",3000 );});

Or in a different way:

jQuery(document).ready(function () {    //hide a div after 3 seconds    setTimeout(function(){ jQuery("#div").hide(); }, 3000);});

Or as a function:

案例：

var timeover;     var timeout;     $(".namelistul li img").mouseover(function(){               clearTimeout(timeover);               clearTimeout(timeout);               var namelistli = $(this).parent();//父节点            timeover = setTimeout(function() {                  if(namelistli.has("span").length==0){                   var $span = $("");                   $(namelistli).prepend($span);                                      }            }, 150);            //删除其他的span               namelistli.siblings().find("span").remove();                                });    $("body").on("mouseout", '.namelistdel', function(){        clearTimeout(timeover); //鼠标离开解除延迟        clearTimeout(timeout);        timeout = setTimeout(function() {                  $(".namelistdel").remove();            }, 150);      });
