先看需求:(不想看的直接拉到最后)
【需求说明】
6、如状态为上架时,库存为必填,下架状态时,库存为可填,前面无星号
实现方法:使用this.$set()和this.$delete()
上代码:
由于设计商业隐私,代码只上传一部分:
<el-form :model="commodityForm" ref="commodityForm" :rules="rules" label-width="120px">
其他字段......
<el-form-item label="上下架状态" prop="status">
<el-switch
v-model="commodityForm.status"
:active-value="1"
:inactive-value="0"
@change="switchChange"
>
</el-switch>
</el-form-item>
</el-form>
表单data中原来的rules:
// 表单校验
rules:{
name: [{ required: true, message: "请输入商品名称", trigger: ['blur','change']}],
title: [{ required: true, message: "请输入商品标题", trigger: ['blur','change']}],
commodityFormImg:[{ required: true, message: '请上传商品图片', trigger: 'change'}],
typeId: [{ required: true, message: '请选择所属分类', trigger: 'change'}],
brandId: [{ required: true, message: '请选择商品品牌', trigger: 'change'}],
specification: [{ required: true, message: '请选择商品规格', trigger: ['blur','change']}],
sellingPrice: [{ required: true, message: '请输入销售价', trigger: ['blur','change']}],
// stock: [{ required: true, message: '请输入库存', trigger: ['blur','change']}],
detail: [
{ required: true, message: "商品详情不能为空", trigger: "blur" },
{ validator: validateEditor, trigger: 'blur,change' }
]
},
不添加上下架状态的rules
在change事件中进行判断:重点方法在这里!!!!!!!!!!
// 上下架开关事件
switchChange(e) {
if(e != 1) {
//删除校验的关键的两行代码(两行都要!!!!!!!!!!!!!!!)
// 这个只能删除文字提示,但是星号还在,
this.$refs["commodityForm"].clearValidate(["stock"]);
// 这个只能删除星号提示,但是文字还在
this.$delete(this.rules,'stock');
}else{
//添加校验代码(!!!!!!!!!!!!!!!)
this.$set(this.rules,'stock',[{ required: true, message: '请输入库存', trigger:
['blur','change']}])
}
}
动态添加删除rules
2023-1-29二更一个最新的方法:
<el-form-item label="库存" prop="stock" :rules="commodityForm.status == 1 ? { required: true, message: '请输入库存', trigger: ['blur','change']} : {}">
<el-input v-model.trim="commodityForm.stock" @input="commodityForm.stock = commodityForm.stock.replace(/[^\d]/g, '')" size="small" placeholder="请输入库存"></el-input>
</el-form-item>
感谢我的好同事教我做事哈哈哈
:rules="commodityForm.status == 1 ? { required: true, message: '请输入库存', trigger: ['blur','change']} : {}"
同时方法中的代码留一个:
switchChange(e) {
if(e != 1) {
this.$refs["commodityForm"].clearValidate(["stock"]);
}
}
