Can';当使用javascript在div标记中移动鼠标时,是否运行onmousemove?

Can';当使用javascript在div标记中移动鼠标时,是否运行onmousemove?,javascript,Javascript,我有一个示例代码: javascript: function bootstrap(id) { this.id = id; this.init = function() { document.getElementById(this.id).onmousemove = positionButton; } function positionButton(e) { e = e || window.event; var cursor = {x:0

我有一个示例代码:

javascript:

function bootstrap(id) {
   this.id = id;
   this.init = function() {
      document.getElementById(this.id).onmousemove = positionButton;
   }
   function positionButton(e) {
      e = e || window.event;
      var cursor = {x:0, y:0};
      if (e.pageX || e.pageY) {
         cursor.x = e.pageX;
         cursor.y = e.pageY;
      } else {
         cursor.x = e.clientX + (document.documentElement.scrollLeft || document.body.scrollLeft) - document.documentElement.clientLeft;
         cursor.y = e.clientY + (document.documentElement.scrollTop || document.body.scrollTop) - document.documentElement.clientTop;
      }
      var elem = document.getElementById(this.id);
      elem.style.position = 'absolute';
      elem.style.top = cursor.y - 10 + 'px';
      elem.style.left = cursor.x - 30 + 'px';
   }
}
在html中:

<div id="button" style="position: absolute; opacity: 1; z-index: 100; width:27px; height:20px; overflow:hidden">
test test
</div>
<script type="text/javascript" src="script.js"></script>
<script>
var bootstrap = new bootstrap('button');
bootstrap.init();
</script>

测试
var bootstrap=新引导(“按钮”);
bootstrap.init();
当我运行代码时,result not run event mousemove,如何修复它?

按钮的样式。 您的代码:

width:27px;height:20px;
我换成

width:60px;height:50px;
我在IE9上试用了它。它很有效。

运行我创建的,只需稍微修改一下您的代码:

    function bootstrap(id) {
        this.id = id;
        this.init = function() {
            document.getElementById(this.id).onmousemove = positionButton;
        };

        function positionButton(e) {
            e = e || window.event;
            var cursor = {
                x: 0,
                y: 0
            };
            if (e.pageX || e.pageY) {
                cursor.x = e.pageX;
                cursor.y = e.pageY;
            } else {
                cursor.x = e.clientX + (document.documentElement.scrollLeft || document.body.scrollLeft) - document.documentElement.clientLeft;
                cursor.y = e.clientY + (document.documentElement.scrollTop || document.body.scrollTop) - document.documentElement.clientTop;
            }
            var elem = document.getElementById(this.id);
            elem.style.position = 'absolute';
            elem.style.top = cursor.y - 10 + 'px';
            elem.style.left = cursor.x - 30 + 'px';
        }
    }

var bootstrap = new bootstrap('button');
bootstrap.init();​
它可以与Chrome、Safari和FFX一起正常工作
