    一、播放声音

      1.页面中的处理:<div  id=”alm”></div>

      2.Js处理:

        function playVoice (value){

          //获取主机地址之后的目录

             var pathName = window.document.location.pathname;

             //获取带"/"的项目名,

             var projectName = pathName.substring(0,

               pathName.substr(1).indexOf('/') + 1);

             //拼接获取声音路径

             value = projectName + value;

             //将原来embed中的声音清空

             document.getElementById("alm").innerHTML = "";

             if (navigator.userAgent.indexOf("MSIE") != -1) {

                 //加入现在选择的声音

                 document.getElementById("alm").innerHTML = '<embed src="'+value+'" quality="high" '+

                    'width="0" height="0" autostart="true"  hidden="true" loop="true" ' +'type="application/x-ms-wmp">'

                    + '</embed>';

             } else {

                 //加入现在选择的声音

                 document.getElementById("alm").innerHTML = '<audio id="aaa" src="'+

            value+'" width="0" height="0" hidden="true" loop="loop" autoplay controls></audio>';

             }

        }

    二、get请求传递中文参数乱码: 

      1.在页面端对url进行编码:

        使用encodeURI(传递的参数值)如:”...?username=”+encodeURI(“中文参数”)

      2.在后台通过解码来接收改中文参数:

        String name=new String(request.getParameter(“username”).getBytes(“ISO-8859-1”),”UTF-8”);
