概述

+ +

onmouseover属性用来获取或设置当前元素的mouseover事件的事件处理函数.

+ +

+ +
element.onmouseover = event handling code
+
+ +

例子

+ +
<!doctype html>
+<html>
+<head>
+<title>onmouseover/onmouseout event example</title>
+<script type="text/javascript">
+    function initElement()
+    {
+        var p = document.getElementById("foo");
+
+        p.onmouseover = showMouseOver;
+        p.onmouseout = showMouseOut;
+    };
+
+    function showMouseOver()
+    {
+        var notice = document.getElementById("notice");
+        notice.innerHTML = '检测到鼠标移进';
+    }
+
+    function showMouseOut()
+    {
+        var notice = document.getElementById("notice");
+        notice.innerHTML = '检测到鼠标移出';
+    }
+
+
+</script>
+<style type="text/css">
+    #foo {
+    border: solid blue 2px;

+</style>
+</head>
+<body onload="initElement()";>
+    <span id="foo">移动鼠标,在该元素上移进移出</span>
+    <div id="notice"></div>
