Javascript 确定鼠标位置

 

 

	ev.pageY	ev.clientY	document.body. scrollTop	document.body. clientTop	scrollPosTop	mousePos.y	window. pageYOffset	document.documentElement. scrollTop
IE6	undefined	281	0	0	1028	281	undefined	1028
IE7	undefined	281	0	0	1028	281	undefined	1028
IE8	undefined	281	0	0	1028	281	undefined	1028
IE9	1306	378	0	0	928	378	928	928
Chrome	1416	408	1008	0	1008	1416	1008	0
Firefox	1132	336	0	0	796	1132	796	796

 

原先的脚本：

   function mouseCoords(ev) {

            var nVer = navigator.appVersion.toString();

            if (nVer.indexOf("MSIE 9.0") != -1) {

                //IE9

                return {

                    x: ev.clientX + document.body.scrollLeft - document.body.clientLeft,

                    y: ev.clientY + document.body.scrollTop - document.body.clientTop

                };

            }

            else {

                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

                };

            }

        }

 

 后来发现应该改为：

   function mouseCoords(ev) {
                return {
                    x: ev.clientX,
                    y: ev.clientY
                };
            }

在IE6、IE7、Ie8、IE9、chrome 11、firefox 3.6下均正常。
