window.onload=function () {
imgLocation("container","box");
}
function imgLocation(parent,content) {
var cparent=document.getElementById("parent");
var ccontent=getChildElement(cparent,content);
var imgWidth=ccontent[0].clientWidth;
var cols= Math.floor(document.documentElement.clientWidth/imgWidth);
cparent.style.cssText="width"+imgWidth*cols+"px";
}
function getChildElement(parent,content) {
var contenArr=[];
var allcontent=parent.getElementsByTagName("*");
for (var i=0;i<allcontent.length;i++){
