[vue] You cannot set a form field before rendering a field associated with the val ，ant 表单赋值问题

You cannot set a form field before rendering a field associated with the val

Warning: You cannot set a form field before rendering a field associated with the value. You can use `getFieldDecorator(id, options)` instead `v-decorator="[id, options]"` to register it before render

网上很多人出现这个问题，大多数是

   setTimeout(()=>{
            this.props.form.setFieldsValue({
                'userName':value.name
            })
        },0)

增加一个时间循环，来将值插入表单中

我的情况是，表单的id没有插入对导致数据回绑出错，搞了很久

    handleChange(ziduan) { 
      // 使用k-form-design组件的form属性修改表单数据   
	  var sb=[]
	  var sb2={} 
	   for (let index = 0; index <this.list.length; index++) {
          const element = this.list[index]   
		  sb.push(element.name+':'+element.value)
		  sb2[element.name]=JSON.parse(element.value)
		} 
	console.log(sb2)
	 this.$nextTick(() => {
	 this.$refs.KFB.setData(sb)
	 
	 })   
    },

 this.$nextTick(() => { 等待表单渲染完毕

 this.$refs.KFB.setData(sb2) 是我的回绑方法

ant的写法是   this.form.setFieldsValue({ })

我这已经有{ 中括号了，所以不需要

sb2={batch_1597715938142: Array(2), input_1597715932742: "很帅的样子33", number_1597715960183: 33}
