vue2.0+Element UI 实现动态增加删除多个表单（点击按钮增删一排输入框）

单个增加表单，Element文档已经给了详细的方案，这里就不详细介绍
今天介绍的是如图：

点击增加按钮，然后增加如图文本框，点击删除。删除这一行的信息

实现：

<el-form  :model="testInfo"  label-width="100px"  :label-position="labelPosition" class="demo-ruleForm"  >
     <div class="button-search">
          <el-row>
           <span>Headers</span>
          </el-row>
          <el-button slot="append" icon="el-icon-plus" size="small" type="primary" @click="addHeader()">添加Header</el-button>
        </div>
        <!-- 动态增加项目 -->
        <!-- 不止一个项目，用div包裹起来 -->
      <div v-for="(item, index) in testInfo.headers" :key="index">
          <div class="div-inline">
             <el-form-item
               :prop="'headers.' + index + '.headerKey'"
               :rules="{
               required: true, message: '不能为空', trigger: 'blur'
              }"  style="width: 100px;">

               <el-input v-model="item.headerKey"  ></el-input>
             </el-form-item>
           </div>

         <span class="distance_style_10">=</span>

          <div class="div-inline distance_style_10">
            <el-form-item
              :prop="'headers.' + index + '.headerVal'"
              :rules="{
                  required: true, message: '不能为空', trigger: 'blur'
                 }"  class="input_width_300">

              <el-input v-model="item.headerVal"  ></el-input>
            </el-form-item>
          </div>
          
          <div class="div-inline distance_style_10">
            <el-form-item>
              <el-link type="primary" :underline="false"  @click.prevent="removeHeader(item,index)">删除</el-link>
            </el-form-item>
          </div>

        </div>
 </el-form>

data中：

 testInfo:{
        headers:[],
        headerKey:'',
        headerVal:'',
      },

methods中：

methods:{
    addHeader(){
      this.testInfo.headers.push({
        headerKey: '',
        headerVal: ''
      })

    },
    removeHeader(item, index){
      this.testInfo.headers.splice(index, 1)
    }
  }

style

 .div-inline{
    display: inline-block;

  }

.button-search{
  display: flex;
  justify-content: space-between;
}

好了，完成了
