对正则exec进行扩展
RegExp.prototype._exec=function(str){var arr,l;if(this.global){this.lastIndex=0;while((a=this.exec(str))!=null){l=a.length;if(arr==undefined)for(var i=0,arr=[];i<l;i++)arr[i]=[];for(var i=1,p={};i<l;i++)arr[i].push(a[i])for(var i=1;i<l;i++)p["p"+i]=arr[i]}return p;}else{return arr.concat(this.exec(str))}}
实例1:
正则Exec的扩展函数。（功能很强的哦）
re=/(\d+).html">(.*?)</g
re.exec(str)
可以得到 {p1:[所有的文件名],p2:[所有的连接名称]}
