<script type="text/javascript">function  jsthread(func,argc){    this.start=function(){        setInterval("func("+argc+")",1000);    }}var thread=new Array(3);for(i=0;i<3;i++){   thread[i]=new jsthread(func,i);   thread[i].start();}function func(argc){    alert(argc);}</script>
类似与一个类里面有一个属于自己的timer
