如何将Confluence插件与jQuery代码结合起来？

Question

我尝试用下面的js文件（文本1）创建一个Confluence插件，但Confluence控制台说下面的错误（文本2），有人可以帮我解决这个问题吗？我想知道jQuery代码是否应该从以下开始：

AJS.toInit(function() {
AJS.$(document).ready(function() {

问题是'class'是一个保留字，而YUI JavaScript压缩器正在抱怨它（这是正确的）。您可以在此处的代码中修复此问题：

var item = $(this);
    elemsDatas.push({
    content: item.html(),
    class: item.attr('class'),
    href: item.attr('href'),
    id: item.attr('id'),
    colid: index % nbCols
});

通过将class: item.attr('class')更改为clazz: item.addr('class')或类似的东西 - 尽管那时您还必须调整访问此属性的所有其他引用。

我相信如果你真的想要的话，你也可以使用'class': item.addr('class')，但是这使得将来访问该物业变得不那么方便。
