适用于所有主流浏览器，给分吧，楼主
document.onkeydown = function()
      {

              event = window.event?window.event:arguments[0];
          var code = event.keyCode?event.keyCode:event.charCode;
          if (code == 13)
          {
              document.getElementById("btn").click();
          }
      }这个兼容
//这个可以使用所有浏览器，event参数传入
        function onTxtKeyDown(event){
         if(event.keyCode = 13){
         document.form1.submit();//form1是form的name属性值
         }
        }

        <input type="text" id="txt1" name="txt1" onkeydown="onTxtKeyDown(event);" />
