assigning dynamically to document.getElementById from an array string

var urlName=new Array("total","pub");
var开发者_StackOverflow社区 query = window.location.search.substring(1);

for (var i=0;i<vars.length;i++) {
    document.getElementById("'"+urlName[i]+"'").innerHTML = pair[i];
}

How can I assign UrlNames dynamically?

You don't need the quotes around urlName[i] since it's a string:

var urlName = ["total","pub"];

for (var i=0;i<urlName.length;i++) {
    document.getElementById(urlName[i]).innerHTML = pair[i];
}
