<body>
<div id="container"></div>
<script>
var formatNumber = function(str,split){
var type = typeof str;
switch (type){
case "number":
str = str.toString();
case "string":
return str.replace(/(d+?)(?=(?:d{3})+$)/g,"$1"+split);
break;
default:
return ;
}
},
arr=["0.3000","22.356","444.456",123456.56,0,"1","111","1211","123456","1457910","aaaa",{"name":"zhangsan"}],
str="<table width='50%' cellspacing='0' cellpadding='0' border='1' align='center'>";
for(var i = 0; i< arr.length;i++){
var ss = arr[i],
format = formatNumber(ss,",");
str += "<tr><td>"+ss+"</td><td>"+format+"</td></tr>";
}
str+="</table>";
document.getElementById("container").innerHTML = str;
</script>
</body>
结果如下图：
