js动态加载css或js

css:

function addStyle(stylePath) {
var container = document.getElementsByTagName("head")[0];
var addStyle = document.createElement("link");
addStyle.rel = "stylesheet";
addStyle.type = "text/css";
addStyle.media = "screen";
addStyle.href = stylePath;
container.appendChild(addStyle);

}

addStyle('css/add.css');

js:

var container = document.getElementsByTagName("head")[0];
var addscript = document.createElement("script");
addscript.type = "text/javascript";
addscript.src = "http://v.westou.com:8083/assets/player.js";
container.appendChild(addscript);
addscript.onload=addscript.onreadystatechange=function(){  
if(!this.readyState||this.readyState=='loaded'||this.readyState=='complete'){  
//操作（加载完后）
}
addscript.onload=addscript.onreadystatechange=null;  

}

接收js传递的参数：

var js = document.getElementsByTagName("script");

for(var i=0;i<js.length;i++){

    if(js[i].src.indexOf("footer.js")>=0){

        var arraytemp = new Array();

        arraytemp = js[i].src.split('?');

        arraytemp = arraytemp[1].split('=');

        alert(arraytemp[0]+"="+arraytemp[1]);

    }

}
