Javascript 将文本替换为表情符号（在Forumotion上）

Forumotion有一个表情符号的kb限制，这使得不可能放置许多50 x 50的GIF

一个人给了我一个ccode，但是它用img alt替换了图片的文本，并且用alt上相同的值替换了论坛上的每个图片。所以，我想用文本来做，并尽可能添加更多的表情符号

代码如下：

var Smileys;

Smileys = {

};

$(function() {
$.each(Smileys, function(key, value) {
    $('img[alt="' + key + '"]').attr('src', value);
});
});
