我遇到了一些 Javascript 错误,想知道是否有人可以帮助我解决这些错误。我对 js 相当陌生,确实需要帮助。这里所说的是有错误的页面。 http://www.gotopeak.com

这是错误:

未捕获类型错误:对象 [object DOMWindow] 的属性“$”不是函数 错误位于第 44 行

这是代码:

    var hoverButton = {
    init : function() {     
        arrButtons = $$('.hover_button');

        for (var i=0; i<arrButtons.length; i++) {
            arrButtons[i].addEvent('mouseover', hoverButton.setOver);   
            arrButtons[i].addEvent('mouseout', hoverButton.setOff);
        }

    },
    setOver : function() {
        buttonImageSource = this.src;
        this.src = buttonImageSource.replace('_off.', '_hover.');
    }, 
    setOff : function() {
        buttonImageSource = this.src;
        if (buttonImageSource.indexOf('_hover.') != -1) {
            this.src = buttonImageSource.replace('_hover.', '_off.');
        }
    }
}

window.addEvent('domready', hoverButton.init);

I'm getting a few Javascript errors and was wondering if anyone could help me out with them. I'm fairly new to js and could really use the help. That being said here is the page with the errors. http://www.gotopeak.com .

Here is the error:

Uncaught TypeError: Property '$' of object [object DOMWindow] is not a function
error is on line 44

Here is the code:

    var hoverButton = {
    init : function() {     
        arrButtons = $('.hover_button');

        for (var i=0; i<arrButtons.length; i++) {
            arrButtons[i].addEvent('mouseover', hoverButton.setOver);   
            arrButtons[i].addEvent('mouseout', hoverButton.setOff);
        }

    },
    setOver : function() {
        buttonImageSource = this.src;
        this.src = buttonImageSource.replace('_off.', '_hover.');
    }, 
    setOff : function() {
        buttonImageSource = this.src;
        if (buttonImageSource.indexOf('_hover.') != -1) {
            this.src = buttonImageSource.replace('_hover.', '_off.');
        }
    }
}

window.addEvent('domready', hoverButton.init);



var screenshots = {
    numScreens : 0,

I would be very grateful and appreciative of any help that I receive on this issue.

您的页面加载 mootools 一次,加载 jQuery 两次,加载 jQuery UI 两次。因为 jQuery 和 mootools 都定义了一个名为“$”的函数,所以这会产生冲突。

您可以通过使用自执行闭包来修复此问题,该闭包将“$”的非冲突版本映射到您实际可以使用的本地“$”变量。

(function($) {
    // your code
})(document.id);

有关 MooTools 的“Dollar 安全模式”的更多信息,请访问 此处

Your page is loading mootools once, jQuery twice and jQuery UI twice. Because both jQuery and mootools define a function named '$', this gives you conflicts.

You can fix this by using a self executing closure that maps the non-conflicted version of '$' to a local '$' variable you can actually use.

(function($) {
    // your code
})(document.id);

More information on MooTools' "Dollar Safe Mode" can be found here.

编辑:请忽略。 igorw 的上述答案是正确的。对不起。

尝试将 $ 符号转换为“jQuery”。 $ 是 JQuery 的快捷方式。 $ 是为 WordPress 中的 Prototype 保留的。

编辑:您也可以尝试 jQuery.noConflict()。它将 $ 的控制权交还给 JQuery(或第一个实现它的库),因此它不会与其他也实现 $ 的库发生冲突。

Edit: please ignore. The above answer by igorw is the correct one. Sorry.

Try converting your $ symbols to "jQuery". $ is a shortcut to JQuery. $ is reserved for Prototype in Wordpress.

Edit: you can also try jQuery.noConflict(). It relinquishes control of $ back to JQuery (or the first library that implements it), so it does not cause conflict with other libraries that also implement $.

这就是我所做的并解决了所有问题,转到index.php文件,立即调用jquery后,放置 < /代码>

this is what I did and solved everything, Go to the index.php file, after calling jquery immediately, place <script type="text/javascript">jQuery.noConflict();</script>
