使用element-ui +Vue时如何解决table里包含表单验证问题
小编这次要给大家分享的是使用element-ui +Vue时如何解决table里包含表单验证问题，文章内容丰富，感兴趣的小伙伴可以来了解一下，希望大家阅读完这篇文章之后能够有所收获。
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>
