js实现防止被iframe的方法
本文实例讲述了js实现防止被iframe的方法。分享给大家供大家参考。具体如下：
方法一：
<script>
//Breakoutofaniframe,ifsomeoneshovesyoursite
//intooneofthosesillytop-barURLshortenerthings.
//
//Passing`this`andre-aliasingas`window`ensures
//thatthewindowobjecthasn'tbeenoverwritten.
//
//Example:
//varwindow='haha,punked!';
//
//Note:Probablyunnecessary,butjustforkicks.
(function(window){
if(window.location!==window.top.location){
window.top.location=window.location;
}
})(this);
</script>
方法二：
<script> //Amorecrypticone-liner,toawe&impress. // //Noneedtoprotect`window`since`this`is //immutable,andatthetopmostlevelmeans //`window`anyways.Here,wecomparelocations //ontheleftsideofthe"&&"andexecutethe //codeinparenthesisifthatconditionis //true(toplocationisn'tiframelocation). // //Otherwise,nothinghappens.It'sbasicallyan //ifstatementwithoutwrappingcurlybrackets. // //Weird,Iknow.Butprettycool,right?:) this.top.location!==this.location&&(this.top.location=this.location); </script>
希望本文所述对大家的javascript程序设计有所帮助。
