返回值:BooleanjQuery.isFunction(obj)

概述

测试对象是否为函数。

注意:jQuery 1.3以后,在IE浏览器里,浏览器提供的函数比如'alert'还有 DOM 元素的方法比如 'getAttribute' 将不认为是函数

参数

objObjectV1.2

用于测试是否为函数的对象

示例

描述:

检测是否为函数

jQuery 代码:
function stub() { } var objs = [ function () {}, { x:15, y:20 }, null, stub, "function" ]; jQuery.each(objs, function (i) { var isFunc = jQuery.isFunction(objs[i]); $("span:eq( " + i + ")").text(isFunc); });
结果:
[ true,false,false,true,false ]
