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')
- })
- 复制代码
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 })
- 复制代码
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
