js中settimeout方法加参数

复制代码 代码如下:

<script type="text/javascript">
function timedMsg()
{
var a ="dd";
var t=setTimeout(function(){ cao(a);},3000)
}
function cao(a)
{
alert(a);
}
</script>
</head>
<input type="button" value="显示定时的警告框" onClick = "timedMsg()">

复制代码 代码如下:

/* for (var i=0;i<points.length;i++){
AddGuiJi(points[i],value);
//var t=setTimeout(function(){ AddGuiJi(points[i],value);},2000*i)
} */

复制代码 代码如下:

var timerr;
function xunhuanlian(points,value){
if(replayi<points.length){
AddGuiJi(points[replayi],value);
replayi++;
timerr=setTimeout(function(){ xunhuanlian(points,value);},1000);
}
else{
replayi =0;
clearTimeout(timerr);
}
/* for (var i=0;i<points.length;i++){
AddGuiJi(points[i],value);
//var t=setTimeout(function(){ AddGuiJi(points[i],value);},2000*i)
} */
}
