jQuery的图像悬停效果错误

Question

I checked this link of SO : Pop Images like Google Images

And tried to setup the image hover effect.

Everything worked fine when i tested it in here

// ibox image zoomer plugin // roXon

(function($) {
    $.fn.ibox = function() {

        // set zoom ratio //
        resize = 20;
        ////////////////////
        var img = this;
        img.parent().append('<div id="ibox" />');
        var ibox = $('#ibox');
        var elX = 0;
        var elY = 0;

        img.each(function() {
            var el = $(this);

            el.mouseenter(function() {
                ibox.html('');
                var elH = el.height();
                elX = el.position().left - 6; // 6 = CSS#ibox padding+border
                elY = el.position().top - 6;
                var h = el.height();
                var w = el.width();
                var wh;
                checkwh = (h < w) ? (wh = (w / h * resize) / 2) : (wh = (w * resize / h) / 2);

                $(this).clone().prependTo(ibox);
                ibox.css({
                    top: elY + 'px',
                    left: elX + 'px'
                });

                ibox.stop().fadeTo(200, 1, function() {
                    $(this).animate({top: '-='+(resize/2), left:'-='+wh},400).children('img').animate({height:'+='+resize},400);
                });
            });

            ibox.mouseleave(function() {
                ibox.html('').hide();
            });
        });
    };
})(jQuery);

$(document).ready(function() {
    $('.item').ibox();
});

But when i added it to my site, I get the following error

Uncaught TypeError: Property '$' of object [object Window] is not a function
    $('.hovermore').ibox();

I guess its because of other jquery effects in the site.

Is there any way to solve this?

Answer 1

尝试使用以下代码启动代码：

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

Answer 2

那是因为您忘记加载jQuery了：

<script type="text/javascript" src="http://code.jquery.com/jquery-1.7.2.js"></script>

Answer 3

Have you included jQuery on your page before calling $('.hovermore').ibox(); ?

Also, I don't think it should matter, but also make sure you're using the latest version of jQuery.

Can you post a link to the page where it doesn't work so we can see all of the code?

Answer 4

You forgot to include the jQuery library.

Visit this demo, go to SAVE -> DOWNLOAD and look at the downloaded file.

http://jsbin.com/ifefop/edit#javascript,html,live

Your document should have:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>

And if you placed the script in an external file:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script src="js/ibox.js"></script>

Answer 5

Please try

jQuery(document).ready(function($) {
    $('.item').ibox();
});

or

jQuery(document).ready(function() {
    jQuery('.item').ibox();
});
