一 概要
在项目中遇到设置签到的情况，如图所示，在后台中需要可以设置签到任务。这就需要用el-table实现动态新增、编辑表格。同时也会遇到动态校验的场景。
在点击新增任务的时候，会给一些默认的属性，isEditor: false, 这个属性是表示你是否需要编辑
addTask() {
this.model.clockTaskList.push({
name: "",
link: "",
number: "",
points: "",
isEditor: false,
picture: []
})
},
isEditor为true的时候输入框显示，然后可以进行编辑，false的时候就显示数据
<el-table-column prop="name" label="任务名称" align="center">
<template slot-scope="scope">
<el-form-item
:prop="'clockTaskList['+scope.$index+'].name'"
:rules="rules.clockTaskList.name"
>
<el-input v-model="scope.row.name" v-show="scope.row.isEditor"/>
</el-form-item>
<span v-show="!scope.row.isEditor">{{ scope.row.name }}</span>
</template>
</el-table-column>
二 动态校验
- :
:prop="'clockTaskList['+scope.$index+'].name'"会被解析为实际的属性名，例如
clockTaskList[0].name、clockTaskList[1].name 等，这取决于 scope.$index的值。这样做可以确保表单控件与 Vue 实例中的数据正确地绑定 - :prop=“‘clockTaskList[’ + index + ‘].name’” 动态地绑定了每个输入框的 name 属性，同时在 v-validate 中也使用了动态属性名来设置验证规则，确保每个任务名称都能被正确地校验。
<el-table-column prop="name" label="任务名称" align="center">
<template slot-scope="scope">
<el-form-item
:prop="'clockTaskList['+scope.$index+'].name'"
:rules="rules.clockTaskList.name"
>
<el-input v-model="scope.row.name" v-show="scope.row.isEditor"/>
</el-form-item>
<span v-show="!scope.row.isEditor">{{ scope.row.name }}</span>
</template>
</el-table-column>
rules: {
points: [
{required: true, message: '请输入签到积分', trigger: 'blur'},
],
continuousPoints: [
{required: true, message: '请输入连续签到积分', trigger: 'blur'},
],
clockTaskList: {
name: [
{required: true, message: "请输入任务名称", trigger: 'blur'}
],
number: [
{required: true, message: "请输入任务数量", trigger: 'blur'}
],
picture: [
{required: true, message: "请上传图片", trigger: 'blur'}
],
points: [
{required: true, message: "请输入积分", trigger: 'blur'}
]
}
},

校验规则
rules: {
points: [
{required: true, message: '请输入签到积分', trigger: 'blur'},
],
continuousPoints: [
{required: true, message: '请输入连续签到积分', trigger: 'blur'},
],
clockTaskList: {
name: [
{required: true, message: "请输入任务名称", trigger: 'blur'}
],
number: [
{required: true, message: "请输入任务数量", trigger: 'blur'}
],

{required: true, message: "请上传图片", trigger: 'blur'}
],
points: [
{required: true, message: "请输入积分", trigger: 'blur'}
]
}
},
delRow(row, index) {
this.model.clockTaskList.splice(index, 1)
},
saveRow(row) {
this.$refs['formApplicationConfig'].validate((valid) => {
if (valid) {
this.$set(row, 'isEditor', false)
this.$set(row, 'link', row.picture ? row.picture.toString() : '')
}
})
},
edit(row) {
row.isEditor = true;
},
addTask() {
this.model.clockTaskList.push({
name: "",
link: "",
number: "",
points: "",
isEditor: false,
picture: []
})
},
四 小结
1.有时候明明给一个变量赋了值，但是他不在页面上中显示。我们可以用this.$set添加一个响应式的变量
this.$set(row, 'isEditor', false)
在 Vue.js 中，this.$set 是一个用于在响应式对象上设置属性的方法。它可以用于在 Vue
实例的数据对象或组件的响应式属性上添加新的属性，确保新添加的属性也是响应式的。
自定义校验
data() {
const validateNoticeTime = (rule, value, callback) => {
if (this.model.timeType === undefined || this.model.timeType === '' || !this.model.time) {
return callback(new Error('请选择通知时间'))
}
callback()
}
const validatePass2 = (rule, value, callback) => {
if (value === '') {
callback(new Error('请再次输入密码'));
} else if (value !== this.ruleForm.pass) {
callback(new Error('两次输入密码不一致!'));
} else {
callback();
}
return {
model: {},
rules: {
name: [
{required: true, message: '请输入任务名称', trigger: 'blur'},
{min: 1, max: 50, message: '长度为1-50位', trigger: 'blur'}
],
noticeTime: [
{validator: validateNoticeTime, trigger: 'blur'}
],
checkPass: [
{ validator: validatePass2, trigger: 'blur' }
],
}
}
},
