现在问题解决了.但是又有个新的问题 移动只能慢慢移动.移动快了以后就会出现鼠标不在框上显示的问题.估计是计算量大吧.想个更好点的 这是我在thickbox中添加的代码:

	//添加移动
			var key = 0;
			var posX;
			var posY;
			$('#TB_title').mousedown(function(e) {
			    //记录鼠标点击下去之后的位置
			    //$("#TB_title").unbind("mousedown");
			    key = 1;
			    posX = e.pageX;
			    posY = e.pageY;
});
			$("#TB_window").mouseup(function(e) {
			    key = 0;
			    posX = e.pageX;
			    posY = e.pageY;
			});
			$("#TB_title").mousemove(function(ev) {
			    if (key == 1) {
			        //$("#TB_title").unbind("mousemove");
			        $("#TB_window").css('left', $("#TB_window").position().left + ev.pageX - posX);
			        $("#TB_window").css('top', $("#TB_window").position().top + ev.pageY - posY);
			        posX = ev.pageX;
			        posY = ev.pageY;
			    }
			});

这么复杂 怎么看 不一致的话 可能产生的原因是你的jquery版本不一样 或者css冲突了 实现不行试试其他弹出框插件 比如art.dialog之类的,都可以实现的

thickbox没试过呢 要不用art.dialog 有完整的文档和demo的,本身就自带你需要的功能

您好: 我的thickbox是在网上下载的一个jquery插件,但是那个插件只是提供了弹出一个页面,而我要做的是让弹出的页面可以移动

 var key = 0;             var posX;             var posY;             $('#TB_title').mousedown(function(e) {                 //记录鼠标点击下去之后的位置                 key = 1;                 posX = e.pageX;                 posY = e.pageY;             });             //unbind             $("#TB_title").mouseup(function() {                 key = 0;                 alert(key);                 $("#TB_title").unbind();             });             $("#TB_title").mousemove(function(ev) {                 if (key == 1) {                     //获取鼠标当前位置                     TB_WIDTH += (-ev.pageX + posX)/2;                     TB_HEIGHT += (-ev.pageY + posY)/2;                     $("#TB_window").css({ marginTop: '-' + parseFloat(TB_HEIGHT / 2) + 'px' });                     $("#TB_window").css({ marginLeft: '-' + parseFloat(TB_WIDTH / 2) + 'px' });                 }             }); 
以上的内容是我添加的内容。事件可以触发,但是得到结果有问题。求帮忙
