最近做项目用的组件库Ant Design Vue,这个组件看起来文档很详细，但也会遇到一些意想不到的问题，最后看文档没办法解决，只能去看源码，折腾了好久，终于把问题给解决了，遇到的问题主要是当添加input的时候验证不能友好的使用，当一个input添加，然后删除，提交表单的时候会提示填写删除的input，还有个问题就是当把填写好的内容，删除提交的时候，已删除的内容还是能提交到后台，用方法处理
form.getFieldValue('email').splice(index, 1)
form.getFieldValue('truename').splice(index, 1)
form.setFieldsValue({
keys: keys.filter(key => key !== index),
email: form.getFieldValue('email'),
truename: form.getFieldValue('truename')
})
这样设置的值的时候，数据还是没删除成功，还能提交到后台，后来才知道需要先注册
注册，这样setFieldsValue方法才能成功，但是添加了之后也没删除成功，
this.form.getFieldDecorator('keys', { initialValue: [0], preserve: true })
this.form.getFieldDecorator('email', { initialValue: [], preserve: false })
this.form.getFieldDecorator('truename', { initialValue: [], preserve: false })
经过看代码后来发现文档里面有个没提示到this.form.clearField('')，用这个方法总算解决了这个问题。
但是上面方法也有个不好的方法就是，keys在删除的时候不能按顺序排列，造成values数组里面也出现了空字段现象，需要重新处理数组，把字段设置成preserve: false。用对象数组循环数据，用循环的中的索引值组成keys，这样在删除，添加的时候，keys的索引跟values数组一直对应，values数组中不会出现空元素现象，在表单提交的时候加上需要验证的字段，这样问题就解决了，大致的代码如下
