js split() 截取函数

var str = "a,b,c";
var kk = str.split(",");//以逗号作为分隔字符串
alert(kk[0]);//a
alert(kk[1]);//b
alert(kk[2]);//c



循环输出每个值

<script language="javascript"> 
str="2,2,3,5,6,6"; //这是一字符串 
var strs= new Array(); //定义一数组 

strs=str.split(","); //字符分割 
for (i=0;i<strs.length ;i++ ) 
{ 
document.write(strs[i]+"<br/>"); //分割后的字符输出 
} 
</script>
