推送到数组并比较两个数组的JavaScript

Question

Hello mates once again,

I try to compare two arrays and do something if they have same components or not. I found here this Using jQuery to compare two arrays Now i try to use it but obvusly im doing something wrong.

This is my JSfiddle where my code is. I put there two alerts to watch my code but it seems there is something wrong with pushing elements to array?

Here is my code:

HTML

<p class="wyliczanka-element">Heh</p>
<p class="wyliczanka-element">huh</p>

JavaScript

$(document).ready(function () {
    var wyliczanka_wzor = [Heh, huh];
    var wyliczanka = [];

    $('.wyliczanka-element').each(function (i) {
        wyliczanka.push($(this).text());
    });
    alert(wyliczanka[0]);

    if (($(wyliczanka_wzor).not(wyliczanka).length === 0) && ($(wyliczanka).not(wyliczanka_wzor).length === 0)) {
        alert("Youp!");
    } else {
        alert("meh");
    }
});

Thanks for any help.

You are comparing two strings to two undefined variables.

var wyliczanka_wzor = [Heh, huh];

should be

var wyliczanka_wzor = ['Heh', 'huh'];
