Js settimeout method plus the use of parameters


Easy to use look at w3school

There’s no argument call in there,

Examples are as follows


<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=” display timing warning box “onClick =” timedMsg()”>

My problem now is between multiple, only the last one comes back. Think about it

Still not quite. Got it


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

The reason for the error in the above is that when time is triggered, I =4, so it is multiple but always the last one

The solution


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)
} */
}
