window.onload = function(e){

      var lastTime,nextTime;
      var lastCode,nextCode;
      var a = "";
      document.onkeypress = function(e) {

         nextCode = e.which;

         nextTime = new Date().getTime();

         if(lastCode != null && lastTime != null && nextTime - lastTime <= 30) {
            code += String.fromCharCode(lastCode);

         } else if(lastCode != null && lastTime != null && nextTime - lastTime > 100){
            code = "";
         }
         lastCode = nextCode;
         lastTime = nextTime;

         if(e.which == 13){

            console.log(code);    //code的值就是扫描枪扫到的值，请问这里如何赋值给bizdata的某个字段, 还有 document,onKeyPress, window.onload都不是x5的标准函数，请问怎么才能正确的在x5里调用，因为我发现放到x5 bex5 5.2.7 的modelonload事件里，扫描枪扫到的值会莫名其妙接收了两次
            code = "";
         }

      }

$(justep.xbl('input1').input).bind('keykeypress', function(evt){evt.preventDefault();});自己监听input的事件啊，什么无相关介绍
