ajax - 如何从 hudson/jenkins jelly 进行 ajax 调用？

Question

我被赋予了开发其他人编写的 Hudson/Jenkins 插件的责任，而我对此并不陌生...

在其中一个 config.jelly 文件中，有 javascript 代码以这种方式开始：

new Ajax.Request("../../descriptorByName/com.mycompany.jenkins.ScriptExecutionBuilder/getParameters", {

我知道它正在尝试使用 ajax 调用指定 java 类的 getParameters 方法，但如果我能得到其中一些问题的答案，我将不胜感激：
1) url 开始使用的相对当前位置是什么"../"
2) "../../descriptorByName" 是什么意思？似乎“descriptorByName”是一个关键字，而不是指某个文件夹位置...
3）我在哪里可以找到“new Ajax.Request”及其参数的描述以及从上下文中调用的含义詹金斯.jelly？
4）我要解决的问题：当这个 ajax 调用是从“全部”视图中的作业触发时，它工作正常（到达 java 类中的方法），但是，如果我用这个创建一个新的 Jenkins 视图在其中工作，当我从视图中触发上述 ajax 调用时，ajax 调用失败 - java 方法永远不会被执行。我得到如下所示的响应。我如何指定 ajax 请求 url “../../descr ...”，使其在从任何视图（不仅仅是“全部”视图）触发时都能工作？

在名为“SpecialView”的视图中配置作业时触发上述ajax时得到的响应是：

<a href="" onclick="document.getElementById('valerr26').style.display='block';return false">ERROR</a><div id="valerr26" style="display:none"><html><body>

我设法通过反复试验找到了解决问题的方法-上面的问题（4）。通过将请求 URL 更改为：

new Ajax.Request("descriptorByName/com.mycompany.jenkins.ScriptExecutionBuilder/getParameters", {

现在它适用于所有观点，但是，我仍然不明白如何以及为什么，并且非常感谢我上面提出的任何问题的答案
