How to know an object is jQuery object or not

2018-06-30 01:57:07

I have created a function which tells whether a variable hold jQuery object or on is there any substitute of this. Below is my code

/*Is there any substitute of this function*/

function iSJqueryObj(elm)
{
    return elm && jQuery.isFunction(elm.html);
}

Use instanceof :

console.log(elm instanceof jQuery);

or:

console.log(elm instanceof $);

尝试一下实例

obj instanceof jQuery
