1、JS部分

function mousePosition(ev){
    if(ev.pageX || ev.pageY){
     return {x:ev.pageX, y:ev.pageY};
     }
     return {
      x:ev.clientX + document.body.scrollLeft - document.body.clientLeft,
      y:ev.clientY + document.body.scrollTop  - document.body.clientTop
      };
}

function mouseMove(ev){
   ev = ev || window.event;
   var mousePos = mousePosition(ev);
   document.getElementById('xxx').value = mousePos.x;
 document.getElementById('yyy').value = mousePos.y;
}

document.onmousemove = mouseMove;
function seashowtip(id,flag,iwidth){
    var my_tips=$("#mytips");
    var tips;
    if($("#"+id).attr("datatype")=="normal"){
        tips="请输入"+$("#"+id).attr("min")+"个到"+$("#"+id).attr("max")+"个之间的字符";
    }else if($("#"+id).attr("datatype")=="number"){
        tips="请输入"+$("#"+id).attr("min")+"到"+$("#"+id).attr("max")+"位的数字";
    }else if($("#"+id).attr("datatype")=="floatdata"){
        tips="请输入有"+$("#"+id).attr("min")+"到"+$("#"+id).attr("max")+"位小数位小于1的小数";
    }
    if(flag){
        my_tips.html(tips);
        my_tips.css("display","");
        my_tips.css("width",iwidth);
              var  l=document.getElementById('xxx').value;
              var  t=document.getElementById('yyy').value;
              my_tips.css("left",l);
              my_tips.css("top",t);
       }
    else
    {
       my_tips.css("display","none");
       }
    }

2、页面部分
