在整合ajax的项目中，动态加载js和动态加载css是必须的

动态加载js

//动态加载样式function add_css(name) {var head = document.getElementsByTagName('head').item(0);var headlist = head.childNodes;for(var i = 0;i < headlist.length;i = i+1){if(headlist[i] != "" && headlist[i].type == "text/css"){if(headlist[i].href != null && headlist[i].href.indexOf(name) > -1){return;}}}var ocss = document.createElement("link");ocss.type = "text/css";ocss.rel = "stylesheet";ocss.href = name;head.appendChild(ocss);}
