var str='1,张三,2,李四,3,王麻子';
var str1="";
var str2="";
var cArray = new Array();
cArray = str.split(',');
for(var i=0;i<cArray.length;i++)
{
            if(i%2 == 0)
            {
              str1 += cArray[i] + ",";
            }
            else
            {
              str2 += cArray[i] + ",";
            }
}
str1 = str1.substring(0,str1.length-1);
str2 = str2.substring(0,str2.length-1);
document.write(str1+"<br>");
document.write(str2);//-->
