How to make the extjs accordion layout example dynamic?
提问by Edward Tanguay
I've pulled out the accordion layout .html and .js files from the extjs examples(below).
我已经从extjs 示例（如下）中提取了手风琴布局 .html 和 .js 文件。
What is the next stepto make this dynamic e.g. how the syntax of a link looks so that the HTML that fills a section under a panel on the left has links which fill the content on the right.
什么是下一个步骤，使这个充满活力例如，如何链接外观的语法，使填充在左侧面板下部分HTML有填补右边的内容链接。
Does anyone know of tutorials which go beyond this shell and show how to make it dynamic, i.e. integrate it in a working application?
有谁知道教程超出了这个 shell 并展示了如何使它动态化，即将它集成到一个工作应用程序中？

There's a billion ways to do it. The question is vague... but here's a very simplistic one. Just have an Ajax function that calls the server and adds the panels dynamically. Say your server provides the following JSON, by calling /links.json
有十亿种方法可以做到。这个问题很模糊……但这是一个非常简单的问题。只需有一个调用服务器并动态添加面板的 Ajax 函数即可。假设您的服务器通过调用 /links.json 提供以下 JSON
{links: ['http://www.google.com'], ['http://www.yahoo.com']}
You would do the following
你会做以下事情
Ext.onReady(function() {
var accordion = new Ext.Panel({
region:'west',
margins:'5 0 5 5',
split:true,
width: 210,
layout:'accordion'
});
new Ext.Viewport({
layout:'border',
items:[
accordion,
{region:'center', html:'This is where the content goes for each selection.'}]
});
Ext.Ajax.request({
url: '/links.json',
callback: function(response) {
var json = Ext.decode(response);
var cfgs = [];
for (var i = 0; i < json.links.length; i++) {
cfgs.push({
html: json.links[i]
})
}
accordion.add(cfgs);
}
});
});
But there's nothing that I coded here that you didn't already know, is there?
但是我在这里编写的任何代码你都不知道，是吗？
