JQuery Uncatch TypeError: object [ object Window ]的属性“ $”不是函数

所有人, 我下载了一个预绑定的 JS/CSS 表单应用程序，并试图在 WordPress 中使用它:

$(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;
};




});

我假设 WordPress 没有冲突导致问题，所以我更新了最后一个括号如下:

}, "jQuery");

但是，我仍然得到相同的错误。有人知道是什么导致了这个问题以及如何解决它吗？

先谢谢你！
