vue動(dòng)態(tài)添加表單validateField驗(yàn)證功能實(shí)現(xiàn)
vue動(dòng)態(tài)添加表單validateField驗(yàn)證,代碼如下所示:
<template> <el-form ref="form" :model="form" :rules="rules" label-width="100px"> <div v-for="(input, index) in inputs" :key="index"> <el-form-item :label="'Name ' + (index + 1)" :prop="'name' + index"> <el-input v-model="input.name" @blur="validateName(index)"></el-input> </el-form-item> <el-form-item :label="'Age ' + (index + 1)" :prop="'age' + index"> <el-input v-model.number="input.age" @blur="validateAge(index)"></el-input> </el-form-item> </div> <el-button type="primary" @click="addInput">Add input</el-button> <el-button type="primary" @click="submitForm">Submit</el-button> </el-form> </template> <script> export default { data() { return { form: {}, inputs: [{name: '',age: ''}], rules: { name0: { required: true, pattern: /^[A-Za-z]+$/, message: 'Name can only contain letters', trigger: 'blur' }, age0: { required: true, pattern: /^\d+$/, message: 'Age can only contain numbers', trigger: 'blur' }, } } }, methods: { addInput() { const index = this.inputs.length this.inputs.push({ name: '', age: '' }) this.$set(this.form, `name${index}`, '') this.$set(this.form, `age${index}`, '') this.$set(this.rules, `name${index}`, { required: true, pattern: /^[A-Za-z]+$/, message: 'Name can only contain letters', trigger: 'blur' }) this.$set(this.rules, `age${index}`, { required: true, pattern: /^\d+$/, message: 'Age can only contain numbers', trigger: 'blur' }) }, validateName(index) { this.$refs.form.validateField(`name${index}`) }, validateAge(index) { this.$refs.form.validateField(`age${index}`) }, submitForm() { this.$refs.form.validate(valid => { if (valid) { // submit form } else { console.log('validation failed') } }) } } } </script>
可以使用 Element UI 的表單組件結(jié)合 Vue 的動(dòng)態(tài)組件來實(shí)現(xiàn)動(dòng)態(tài)添加多組輸入框,并對(duì)每個(gè)輸入框進(jìn)行校驗(yàn)。Element UI 提供了很多內(nèi)置的校驗(yàn)規(guī)則和提示信息,可以方便地應(yīng)用到表單中。
首先,我們需要在 Vue 實(shí)例中聲明一個(gè) inputs 數(shù)組來存儲(chǔ)每個(gè)輸入組的數(shù)據(jù)。在添加輸入組時(shí),我們只需要向 inputs 數(shù)組中添加一個(gè)新的對(duì)象即可。
在模板中,我們使用 Element UI 的表單組件來渲染輸入框,并使用 v-for 指令循環(huán)渲染多組輸入框。在每個(gè)輸入框中,我們使用 v-model 指令將輸入值綁定到 inputs 數(shù)組中的數(shù)據(jù)屬性上。對(duì)于 name 和 age 輸入框,我們使用 pattern 規(guī)則來進(jìn)行校驗(yàn),并在 rules 對(duì)象中提供了相應(yīng)的錯(cuò)誤提示信息。在 checkNameInput 和 checkAgeInput 方法中,我們調(diào)用 $refs.form.validateField 方法來手動(dòng)觸發(fā)校驗(yàn),并將當(dāng)前輸入對(duì)象作為參數(shù)傳遞進(jìn)去。
最后,我們需要在 Vue 實(shí)例中聲明一個(gè) form 對(duì)象來維護(hù)表單數(shù)據(jù),并將 rules 對(duì)象傳遞給 el-form 組件的 rules 屬性。這樣,每次輸入框的值發(fā)生變化時(shí),就會(huì)自動(dòng)觸發(fā) Element UI 的校驗(yàn)機(jī)制,并顯示相應(yīng)的錯(cuò)誤提示信息。

主要就是prop的問題,prop要對(duì)應(yīng)到數(shù)據(jù)。
