添加版本号解决浏览器缓存

方法1

<script>
    var projectVersion = "1.0";
    createScript("/static/index.js");
    function createScript(url){
        var script = document.createElement('script');  //创建script标签
        script.type = "text/javascript";
        script.src = url+"?v="+projectVersion ;
        document.getElementsByTagName('head')[0].appendChild(script);
    }
</script>

方法2

<script>
    var projectVersion = "1.0";
    document.write("<script src='/static/index.js?v="+projectVersion +"'><script>");
    document.write("<link rel='stylesheet' href='/static/index.css?v="+projectVersion+"'>");
</script>

在jsp页面上添加

<link rel="stylesheet" href="/static/index.css?v=<%=session.getAttribute("VERSION")%>">
<script src="/static/index.js?v=<%=session.getAttribute("VERSION")%>"></script>
