ElementUI 之el-form表单重置功能按钮

Posted 2021-08-16 在奋斗的大道

业务场景：

使用el-form时，点击重置按钮或者取消按钮时会实现表单重置效果。

重置功能按钮功能实现详细步骤:

第一:首先给el-form添加ref属性。

  <el-form :inline="true" :model="queryParams" ref="queryForm">

第二：在点击重置按钮执行的方法中，执行如下功能代码片段

 reset(){
        # 重新设置请求参数实体属性
        this.queryParams = {
          memberName: undefined,
          typeId: undefined,
        };
        # 指定表单属性值重置
        this.$refs["form" ].resetFields();
      }
