element-ui表单只验证单个字段

1. 表单只验证单个字段

this.$refs['form'].validateField('mobile', valid => {
  if (valid) {
    // 发送验证码
  }
})

2. 弹框关闭时清空表单项

<el-dialog @close="onClose">
  <el-form ref="form">
  </el-form>
</el-dialog>

// 弹窗关闭时重置表单
onClose() {
  this.$refs['form'].resetFields()
}

3. 表格跨分页多选

<el-table row-key="id">
  <el-table-column type="selection" reserve-selection></el-table-column>
</el-table>
