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!

Solution 1:

This is a syntax issue, the jQuery library included with WordPress loads in "no conflict" mode. This is to prevent compatibility problems with other javascript libraries that WordPress can load. In "no-confict" mode, the $ shortcut is not available and the longer jQuery is used, i.e.

jQuery(document).ready(function ($) {

By including the $ in parenthesis after the function call you can then use this shortcut within the code block.

For full details see WordPress Codex

Solution 2:

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
