1、creatTextNode兼容

    function fn(code){
        var script = document.createElement("script");
        script.type = "text/javascript";
        try{
            script.appendChild(document.createTextNode(code)); //IE9下不兼容
        }catch(ex){
            script.text = code ;
        };
        document.body.appendChild(script);
    };
    fn("alert(1)");
