通过fieldlist动态添加的组件，是没法自动渲染的。
fa官网也只对10个内置的组件，提供了重新渲染的方法。以下是：十个组件，两种方法。
方法1：全部重新渲染 Form.api.bindevent("form[role=form]")
方法2: 精确渲染 并提供了10个组件精确渲染的方法，如下图
1.编辑器一般都是官方提供的收费插件
2.安装插件的时候，插件本身就提供了渲染方法。（我安装的是官方的nkeditor插件）
3.具体的渲染方法，写在\public\assets\js\backend\addon.js里
4.从addon.js里复制编辑器插件的渲染方法，写到\public\assets\js\require-form.js里。
5.具体的写法是，跟十个组件同级的地方，添加一个editor方法，内容来自addon.js里编辑器的渲染方法。
6.以后就直接调用这个方法，就能渲染。调用方式：Form.events.editor($("form"));

1.给每个想要展示编辑器的地方，先加上一个class，我定义为myeditor
2.使用JS，为每个myeditor类，动态的添加editor类
以cms中的archives控制器为例，找到\public\assets\js\backend\cms\archives.js
在js中的add方法中，添加一些代码。以下为添加位置和具体代码
$(‘body‘).on(‘click‘, ‘.myeditor‘, function(){
var cunzai = $(this).prev().length > 0
console.log(cunzai)
if(cunzai){
$(‘.ke-container‘).hide()
$(‘.myeditor‘).show()
$(this).prev().show()
$(this).hide()
}else{
// 让所有的编辑器隐藏，并且显示输入框，
$(‘.ke-container‘).hide()
$(‘.myeditor‘).show()
// $(‘.myeditor‘).removeClass(‘editor‘)
// 新增编辑器类
$(this).addClass(‘editor‘)
// 添加完成以后，使用先的方法，初始化编辑器，会提示错误 Uncaught TypeError: form.is is not a function
// Controller.api.bindevent();
Form.events.editor("form");
console.log(‘创建完成‘)
}})
