##动态插入jquery

    (function(){
        var scip = document.createElement("script");

        newatt=scip.setAttribute("src","http://code.jquery.com/jquery-1.7.1.min.js");
        newatt=scip.setAttribute("type","text/javascript");
        newatt=scip.setAttribute("charset","utf-8");
        
        x=document.getElementsByTagName("head")[0];
        x.appendChild(scip);
    })()

##修改让其浮动在右上 $(“#float”).css({ top: “10px”,right: “10px”, width: “300”, position: “fixed”, background: “#99ff00” });
