表单校验

<script setup>
import { ref } from "vue";
// 登录的表单数据(绑定到最外层的from标签上)
//里面的每个属性都与element-plus的表单标签进行双向绑定,具体可以看html代码
const loginForm = ref({
  username: "",
  password: "",
  loginpassword: "",
});
// 用户名校验(自定义校验,其中value为输入的数据)
const usernamevalidator = (rule, value, callback) => {
  const regMobile = /^[\w-]{4,16}$/;
  if (regMobile.test(value)) {
    return callback();
  }
  return callback(new Error("请输入4-16位数字或大小写字母或者字符"));
};
// 密码校验(自定义校验,其中value为输入的数据)
const passwordvalidator = (rule, value, callback) => {
  const regMobile =
    /^(?![a-zA-Z]+$)(?![A-Z0-9]+$)(?![A-Z\W_!@#$%^&*`~()-+=]+$)(?![a-z0-9]+$)(?![a-z\W_!@#$%^&*`~()-+=]+$)(?![0-9\W_!@#$%^&*`~()-+=]+$)[a-zA-Z0-9\W_!@#$%^&*`~()-+=]/;
  if (regMobile.test(value)) {
    return callback();
  }
  return callback(new Error("请输入数字或大小写字母或者字符任意三项即可"));
};
// 确认密码校验(自定义校验,其中value为输入的数据)
const loginpasswordvalidator = (rule, value, callback) => {
  if (loginForm.value.password === value) {
    return callback();
  }
  return callback(new Error("两次输入不一致"));
};
// 登录数据的校验规则(下面的每个属性就是针对每个表单元素的校验,在标签的prop属性绑定)
//validator为自定义校验,值为上面的自定义规则
const loginrules = ref({
  username: [
    { required: true, message: "账号不能为空", trigger: "blur" },
    { validator: usernamevalidator, trigger: "blur" },
  ],
  password: [
    { required: true, message: "密码不能为空", trigger: "blur" },
    { validator: passwordvalidator, trigger: "blur" },
  ],
  loginpassword: [
    { required: true, message: "确认密码不能为空", trigger: "blur" },
    { validator: loginpasswordvalidator, trigger: "blur" },
  ],
});
//这个baseForm为获取表单的对象ref值,用于对表单规则是否通过进行校验,baseForm绑定到form标签上,具体可以看下面的html代码
const baseForm = ref(null);
const submitForm = () => {
//对表单元素进行校验
  baseForm.value.validate((valid) => {
    if (!valid) {
    //校验失败
      console.log("请调整数据后再请求");
      return false;
    }
    // 校验成功
    console.log("123123", 123123);
  });
};

多选表格

<script setup>

//需要绑定的数据
const defaultData = reactive({

    },
    {
      id: "04",
      name: "测试004",
    },
  ],
});
// 前面的多选框勾中会触发的事件(val为勾选的数据组成的数组)
const handleSelectionChange = (val) => {
  console.log("val", val);
};
</script>

<template>
  <!-- data绑定的是数据,selection-change代表勾选的数据,默认有个参数表示勾选上的数据组成的数组 -->
  <el-table
    :data="defaultData.tableData"
    style="width: 100%"
    @selection-change="handleSelectionChange"

    <!-- 多选框 -->
    <el-table-column
      type="selection"
      width="55"

    <!-- label绑定的是当前的标题, property绑定的是数据里面的某个需要展示的属性-->
    <el-table-column
