点击事件里给button标签加一个自定义属性，存上次点击时间
求详细代码，JS 真心的没怎么做过
<input type="button" id="submit" value="提交"><script>$(document).ready(function(){ $("#submit").click(function(){ var nowTime = new Date().getTime(); var clickTime = $(this).attr("ctime"); if( clickTime != ‘undefined‘ && (nowTime - clickTime < 5000)){ alert(‘操作过于频繁，稍后再试‘); return false; }else{ $(this).attr("ctime",nowTime); alert(‘提交成功‘); } }); });</script>原文：http://www.cnblogs.com/try-better-tomorrow/p/5142587.html
