本实例使用了javascript的onmousemove 事件。onmousemove 事件会在鼠标指针移动时发生。
语法
onmousemove="SomeJavaScriptCode"
SomeJavaScriptCode是必需参数。规定该事件发生时执行的 JavaScript。
下面是核心代码(完整代码请在效果页面查看源代码):
<script type="text/javascript">
function KeleyiImgNext(bigimg) {
var lefturl = "01.html";
var righturl ="03.html";
var imgurl = righturl;
var width = bigimg.width;
var height = bigimg.height;
bigimg.onmousedown = bigimg.onmousemove = function () {
if (event.offsetX < width / 2) {
imgurl = lefturl;
if (imgurl != "#")
bigimg.style.cursor = 'url(images/arr_left.cur),auto';
else
bigimg.style.cursor = 'default';
} else {
imgurl = righturl;
if (imgurl != '#')
bigimg.style.cursor = 'url(images/arr_right.cur),auto';
else
bigimg.style.cursor = 'default';
}
}
bigimg.onmouseup = function () {
if (imgurl != '#')
top.location = imgurl;
}
}
</script>
