【VUE】el-table表格内输入框或者其他控件规则校验实现

1、封装组件

1、规则校验一般基于form表单实现，因此需要给具体控件套一层form表单
新建组件input-required.vue，内容如下

<template><div><el-form ref="formRef" :model="form" :rules="formRules" label-width="0px" style="font-size:0.6vw"><el-form-item :prop="this.propValue"><el-inputv-model="value":placeholder="`请输入${labelValue}`"autocomplete="off":disabled="isDisalbed"@change="isValid"></el-input></el-form-item></el-form></div>
</template><script>export default {data() {return {value: "",form: {},formRules: {}};},// 子组件使用props来接收父组件内传过来的数据props: ["propValue", "labelValue", "isDisalbed", "indexValue"],created() {// 给子组件的对象动态添加属性并设置属性值this.$set(this.form, this.propValue, "");this.$set(this.formRules, this.propValue, [{ required: true, message: `${this.labelValue}不能为空`, trigger: "blur" }]);},methods: {// el-input失去焦点后会校验数据,空的话会提示,符合校验规则会触发父组件内方法更新视图数据isValid() {let flag = null;this.form[this.propValue] = this.value;this.$refs["formRef"].validate(valid => {if (valid) {flag = true;this.$emit("updateData", this.form, this.indexValue);} else {flag = false;}});// 把每次校验的结果返回给父组件return flag;}},};
</script><style>
</style>

2、组件使用

组件引入

import InputRequired from "/src/components/inputRequired/input-required.vue";
components: {InputRequired},

form表单里的table使用组件，isRequiredNumber（v-if=“scope.row.isRequiredNumber == ‘0’”）是否必填标识（看自己业务需求，这个必填在此处判断因为业务需求是可配置是否必填的，只做必填可以去掉该判断，正常使用input-required）

.......
<el-col :span="21"><el-form-item label="资源" prop="resourcePrepare"><el-table :data="resourceResult" :header-cell-style="{ background: '#f0f2f5' }"><el-table-column align="center" prop="name" label="名称"></el-table-column><el-table-column align="center" prop="num" label="数量"><template slot-scope="scope"><el-input v-if="scope.row.isRequiredNumber == '0'" v-model="scope.row.num"placeholder="请输入内容"></el-input><input-required v-else :ref="`requiredNum${scope.$index}`":propValue="'num'" :labelValue="'数量'" :isDisalbed="false":indexValue="scope.$index" @updateData="updateData"></input-required></template></el-table-column><el-table-column label="" width="90"><template slot-scope="scope"><span @click="delResourcePrepare(scope.row)"class="el-icon-close txtClose"></span></template></el-table-column></el-table></el-form-item>
</el-col>
..........

提交表单做必填校验

submitForm() {this.$refs["form"].validate(valid => {let flag = true;//循环判断table里的所有数据for (let index = 0; index < this.resourceResult.length; index++) {//资源数量是否必填（业务需要正常使用可去掉判断）if (this.resourceResult[index].isRequiredNumber == '1') {flag = flag && this.$refs[`requiredNum` + index].isValid();}}if (!flag) {//必填校验未通过，结束方法return;}.....其他业务.....});
},

大概就是这样了。。。
