应用场景:
在实际使用中经常会遇到需要在Form表单中使用table表格进行表单提交,同时又需要对table的字段进行校验,效果如图所示:
这个校验中,最关键的问题在于如何给el-form-item 动态绑定prop。
:prop="'tableData.' + scope.$index + '.字段名'"
方法一:
<template> <div class="app-container"> <el-form :model="fromData" ref="from"> <el-table :data="fromData.domains"> <el-table-column label="姓名"> <template slot-scope="scope"> <el-form-item :prop="'domains.'+scope.$index+'.name'" :rules="fromaDataRules.name"> <el-input v-model="scope.row.name"></el-input> </el-form-item> </template> </el-table-column> <el-table-column label="地址"> <template slot-scope="scope"> <el-form-item :prop="'domains.'+scope.$index+'.desc'" :rules="fromaDataRules.desc"> <el-input v-model="scope.row.desc"></el-input> </el-form-item> </template> </el-table-column> </el-table> </el-form> <el-button type="warning" @click="submit('from')">submit</el-button> </div> </template> <script> export default { data() { return { fromData:{ domains:undefined }, fromaDataRules:{ name:[{ required: true, message: '请输入', trigger: 'blur' }], desc:[ { required: true, message: '请填写', trigger: 'blur' }] }, domains:[], } }, mounted(){ this.initDomains() }, methods:{ initDomains(){ this.domains=[ { name: "小红", desc: "11123" }, { name: "小红", desc: "11123" } ] }, init(){ this.$set(this.fromData,'domains',this.domains) }, submit(formName){ this.$refs[formName].validate((valid) => { if (valid) { alert('submit!'); } else { console.log('error submit!!'); return false; } }); } } } </script>
上述代码中比较关键的部分有一下两点:
1、:prop="‘domains.'+scope.$index+'.name'" ,用于动态绑定prop到el-form-item;
2、this.$set(this.fromData,‘domains',this.domains) ,用于为fromData设置domains这个节点。
方法二:
<template> <div class="app-container"> <el-form :model="fromData" ref="from"> <el-table :data="fromData.domains"> <el-table-column label="姓名"> <template slot-scope="scope"> <el-form-item :prop="'domains.'+scope.$index+'.name'" :rules="fromData.fromaDataRules.name"> <el-input v-model="scope.row.name"></el-input> </el-form-item> </template> </el-table-column> <el-table-column label="地址"> <template slot-scope="scope"> <el-form-item :prop="'domains.'+scope.$index+'.desc'" :rules="fromData.fromaDataRules.desc"> <el-input v-model="scope.row.desc"></el-input> </el-form-item> </template> </el-table-column> </el-table> </el-form> <el-button type="warning" @click="submit('from')">submit</el-button> </div> </template> <script> export default { data() { return { fromData:{ fromaDataRules:{ name:[{ required: true, message: '请输入', trigger: 'blur' }], desc:[ { required: true, message: '请填写', trigger: 'blur' }] }, domains:[], }, } }, mounted(){ this.initDomains() }, methods:{ initDomains(){ this.fromData.domains=[ { name: "小红", desc: "11123" }, { name: "小红", desc: "11123" } ] }, init(){ }, submit(formName){ this.$refs[formName].validate((valid) => { if (valid) { alert('submit!'); } else { console.log('error submit!!'); return false; } }); } } } </script>
补充知识:Vue+ElementUI 完整增删查改验证功能的表格
我就废话不多说了,大家还是直接看代码吧~
<template> <div class="block"> <el-col> <el-row> <el-form> <el-form-item> <el-input style="width: 250px;float: left" placeholder="请输入名称" v-model="query"></el-input> <el-button @click="handleSelect" style="float: left;margin-left: 10px">查询</el-button> <el-button @click="handleAdd" style="float: left;margin-left: 10px">新增</el-button> </el-form-item> </el-form> </el-row> <el-row> <el-table :data="tableData" style="width: 100%" border> <el-table-column prop="date" label="日期" width="250"> </el-table-column> <el-table-column prop="name" label="姓名" width="250"> </el-table-column> <el-table-column prop="address" label="地址" width="350"> </el-table-column> <el-table-column> <template slot-scope="scope"> <el-button size="mini" @click="handleEdit(scope.$index,scope.row)">编辑</el-button> <el-button size="mini" type="danger" @click="handleDelete(scope.$index,scope.row)">删除</el-button> </template> </el-table-column> </el-table> </el-row> <el-row> <el-dialog class="dialog" :title="operation===true " :visible.sync="dialogVisible" width="350px" > <el-form label-width="80px" :model="lineData" :rules="addRule" ref="lineData" > <el-form-item label="日期" prop="date"> <el-input v-model="lineData.date"></el-input> </el-form-item> <el-form-item label="姓名" prop="name"> <el-input v-model="lineData.name"></el-input> </el-form-item> <el-form-item label="地址"> <el-input v-model="lineData.address"></el-input> </el-form-item> <el-form-item> <el-button @click="handleSave" type="primary">确定</el-button> <el-button @click="handleCancel">取消</el-button> </el-form-item> </el-form> </el-dialog> </el-row> </el-col> </div> </template> <script>export default { data () { return { operation: true, dialogVisible: false, lineData: {}, editData: {}, query: '', addRule: { date: [{required: true, message: '请输入日期', trigger: 'blur'}], name: [{required: true, message: '请输入名称', trigger: 'blur'}] }, tableData: [{ id: 1, date: '2016-05-02', name: '王一虎', address: '上海市普陀区金沙江路 1518 弄' }, { id: 2, date: '2016-05-04', name: '王二虎', address: '上海市普陀区金沙江路 1517 弄' }, { id: 3, date: '2016-05-01', name: '王一虎', address: '上海市普陀区金沙江路 1519 弄' }, { id: 4, date: '2016-05-03', name: '王四虎', address: '上海市普陀区金沙江路 1516 弄' }] } }, methods: { handleEdit (index, row) { this.editData = JSON.stringify(row) this.lineData = JSON.parse(this.editData) this.dialogVisible = true this.operation = false }, handleDelete (index, row) { this.tableData.splice(index, 1) }, handleAdd () { this.dialogVisible = true this.operation = true this.lineData = {} this.lineData.id = Math.random() }, handleSelect () { if (this.query !== '') { const tmpData = [] for (let item of this.tableData) { if (item.name === this.query) { tmpData.push(item) } } this.tableData = tmpData } }, handleSave () { this.$refs.lineData.validate((valid) => { if (valid) { this.addLine(this.lineData) this.dialogVisible = false } else { alert('保存失败') return false } }) }, handleCancel () { this.dialogVisible = false }, addLine (item) { let existed = false for (let i = 0; i < this.tableData.length; i++) { if (this.tableData[i].id === item.id) { this.tableData[i].id = item.id this.tableData[i].name = item.name this.tableData[i].address = item.address this.tableData[i].date = item.date existed = true break } } if (!existed) { this.tableData.push(this.lineData) } } } } </script> <style scoped> .block{ width: 75%; margin-left: 400px; margin-top: 200px; } </style>
