[jquery] jQuery Uncaught TypeError: Property '$' of object [object Window] is not a function

All, I downloaded a prebundled JS/CSS form application and I'm trying to use it in Wordpress. I've got the following code:

$(document).ready(function () {


/*----------------------------------------------------------------------*/
/* Parse the data from an data-attribute of DOM Elements
/*----------------------------------------------------------------------*/


$.parseData = function (data, returnArray) {
    if (/^\[(.*)\]$/.test(data)) { //array
        data = data.substr(1, data.length - 2).split(',');
    }
    if (returnArray && !$.isArray(data) && data != null) {
        data = Array(data);
    }
    return data;
};

/*----------------------------------------------------------------------*/
/* Image Preloader
/* http://engineeredweb.com/blog/09/12/preloading-images-jquery-and-javascript
/*----------------------------------------------------------------------*/



// Arguments are image paths relative to the current page.
$.preload = function() {
    var cache = [],
        args_len = arguments.length;
    for (var i = args_len; i--;) {
        var cacheImage = document.createElement('img');
        cacheImage.src = arguments[i];
        cache.push(cacheImage);
    }
};


/*----------------------------------------------------------------------*/
/* fadeInSlide by revaxarts.com
/* Fades out a box and slide it up before it will get removed
/*----------------------------------------------------------------------*/


$.fn.fadeInSlide = function (speed, callback) {
    if ($.isFunction(speed)) callback = speed;
    if (!speed) speed = 200;
    if (!callback) callback = function () {};
    this.each(function () {

        var $this = $(this);
        $this.fadeTo(speed / 2, 1).slideDown(speed / 2, function () {
            callback();
        });
    });
    return this;
};


/*----------------------------------------------------------------------*/
/* fadeOutSlide by revaxarts.com
/* Fades out a box and slide it up before it will get removed
/*----------------------------------------------------------------------*/


$.fn.fadeOutSlide = function (speed, callback) {
    if ($.isFunction(speed)) callback = speed;
    if (!speed) speed = 200;
    if (!callback) callback = function () {};
    this.each(function () {

        var $this = $(this);
        $this.fadeTo(speed / 2, 0).slideUp(speed / 2, function () {
            $this.remove();
            callback();
        });
    });
    return this;
};

/*----------------------------------------------------------------------*/
/* textFadeOut by revaxarts.com
/* Fades out a box and slide it up before it will get removed
/*----------------------------------------------------------------------*/


$.fn.textFadeOut = function (text, delay, callback) {
    if (!text) return false;
    if ($.isFunction(delay)) callback = delay;
    if (!delay) delay = 2000;
    if (!callback) callback = function () {};
    this.each(function () {

        var $this = $(this);
        $this.stop().text(text).show().delay(delay).fadeOut(1000,function(){
            $this.text('').show();
            callback();
        })
    });
    return this;
};

/*----------------------------------------------------------------------*/
/* leadingZero by revaxarts.com
/* adds a leding zero if necessary
/*----------------------------------------------------------------------*/


$.leadingZero = function (value) {
    value = parseInt(value, 10);
    if(!isNaN(value)) {
        (value < 10) ? value = '0' + value : value;
    }
    return value;
};


});

I was assuming that the Wordpress no conflict was causing an issue so I updated the very last bracket to look like the following:

}, "jQuery");

However, I'm still getting the same error. Does anyone know what would be casuing this issue and how to get it resolved?

Thanks in advance!

maybe you have code like this before the jquery:

var $jq=jQuery.noConflict();
$jq('ul.menu').lavaLamp({
    fx: "backout", 
    speed: 700
});

and them was Conflict

you can change $ to (jQuery)

In Wordpress just replace

$(function(){...});

with

jQuery(function(){...});

You can consider to replace default WordPress jQuery script with Google Library by adding something like the following into theme functions.php file:

function modify_jquery() {
    if (!is_admin()) {
        wp_deregister_script('jquery');
        wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js', false, '1.10.2');
        wp_enqueue_script('jquery');
    }
}
add_action('init', 'modify_jquery');

Code taken from here: http://www.wpbeginner.com/wp-themes/replace-default-wordpress-jquery-script-with-google-library/

My favorite no-conflict-friendly construct:

jQuery(function($) {
  // ...
});

Calling jQuery with a function pointer is a shortcut for $(document).ready(...)

Or as we say in coffeescript:

jQuery ($) ->
  # code here
