概述

用来删除由.prop()方法设置的属性集

随着一些内置属性的DOM元素或window对象,如果试图将删除该属性,浏览器可能会产生错误。jQuery第一次分配undefined值的属性,而忽略了浏览器生成的任何错误

参数

propertyNameStringV1.6

要删除的属性名

示例

描述:

设置一个段落数字属性,然后将其删除。

HTML 代码:
<p> </p>
jQuery 代码:
var $para = $("p");
$para.prop("luggageCode", 1234);
$para.append("The secret luggage code is: ", String($para.prop("luggageCode")), ". ");
$para.removeProp("luggageCode");
$para.append("Now the secret luggage code is: ", String($para.prop("luggageCode")), ". ");
结果:
The secret luggage code is: 1234. Now the secret luggage code is: undefined.
