Jquery method to remove mouse events:
Method 1: Use unbind() method
## The #unbind() method removes the event handler of the selected element. This method can remove all or selected event handlers, or terminate the execution of the specified function when an event occurs. ubind() works with any event handler attached via jQuery. Example:<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<script src="js/jquery-1.10.2.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$("p").click(function() {
$(this).slideToggle();
});
$("button").click(function() {
$("p").unbind();
});
});
</script>
</head>
<body>
<p>这是一个段落。</p>
<p>这是另一个段落。</p>
<p>点击任何段落可以令其消失。包括本段落。</p>
<button>删除 p 元素的事件处理器</button>
</body>
</html>
Method 2: Use undelegate() method
undelegate() Method removes one or more event handlers added by the delegate() method. Example:<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<script src="js/jquery-1.10.2.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$("body").delegate("p", "click", function() {
$(this).slideToggle();
});
$("button").click(function() {
$("body").undelegate();
});
});
</script>
</head>
<body>
<p>这是一个段落。</p>
<p>这是另一个段落。</p>
<p>点击任何段落可以令其消失。包括本段落。</p>
<button>删除点击事件</button>
</body>
</html>
Method 3: Use off() method
off() method is usually used For removing event handlers added via the on() method.<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<script src="js/jquery-1.10.2.min.js"></script>
<script>
$(document).ready(function() {
$("p").on("click", function() {
$(this).css("background-color", "pink");
});
$("button").click(function() {
$("p").off();
});
});
</script>
</head>
<body>
<p>点击这个段落修改它的背景颜色。</p>
<p>点击一下按钮再点击这个段落( click 事件被移除 )。</p>
<button>移除 click 事件</button>
</body>
</html>

Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
