SPA项目CRUD与表单验证
本文介绍了一个SPA项目的CRUD操作实现，包括搜索、添加、编辑、删除功能，并详细讲解了表单验证的使用，如规则设定、表单区分及验证信息清除。同时，文章还展示了如何通过Vue.js和Element UI实现这些功能。
SPA项目开发之CRUD+表单验证
功能：
1、dialog布局
<template>
<div>
<!-- 搜索筛选 -->
<el-form :inline="true" :model="formInline" class="user-search">
<el-form-item label="搜索：">
<el-input size="small" v-model="formInline.title" placeholder="输入文章标题"></el-input>
</el-form-item>
<el-form-item>
<el-button size="small" type="primary" icon="el-icon-search" @click="search">搜索</el-button>
<el-button size="small" type="primary" icon="el-icon-plus" @click="add">添加</el-button>
</el-form-item>
</el-form>
<el-table size="small" :data="listData" border element-loading-text="拼命加载中">
<el-table-column prop="id" label="ID" width="300">
</el-table-column>
<el-table-column prop="title" label="文章标题" width="300">
</el-table-column>
<el-table-column prop="body" label="文章内容" width="300">
</el-table-column>
<el-table-column align="center" label="操作" min-width="300">
<template slot-scope="scope">
<el-button size="mini" @click="edit(scope.$index, scope.row)">编辑</el-button>
<el-button size="mini" type="danger" @click="del(scope.$index, scope.row)">删除</el-button>
</template>
</el-table-column>
</el-table>
<!-- 分页条 -->
<el-pagination style="margin-top: 20px;" @size-change="handleSizeChange" @current-change="handleCurrentChange"
:current-page="formInline.page" :page-sizes="[10, 20, 30, 50]" :page-size="formInline.rows" layout="total, sizes, prev, pager, next, jumper"
:total="total">
</el-pagination>
<!-- 编辑界面 -->
<el-dialog :title="title" :visible.sync="editFormVisible" width="30%" @click="closeDialog">
<el-form label-width="120px" :model="editForm" :rules="rules" ref="editForm">
<el-form-item label="文章标题" prop="title">
<el-input size="small" v-model="editForm.title" auto-complete="off" placeholder="请输入文章标题"></el-input>
</el-form-item>
<el-form-item label="文章内容" prop="body">
<el-input size="small" v-model="editForm.body" auto-complete="off" placeholder="请输入文章内容"></el-input>
</el-form-item>
</el-form>
<div slot="footer" class="dialog-footer">
<el-button size="small" @click="closeDialog">取消</el-button>
<el-button size="small" type="primary" class="title" @click="submitForm">保存</el-button>
</div>
</el-dialog>
</div>
</template>
2、表单验证
Form组件提供了表单验证的功能，只需要通过 rules 属性传入约定的验证规则，
并将Form-Item的prop属性设置为需校验的字段名即可<el-form-item label="活动名称" prop="name"> <el-form :model="ruleForm" :rules="rules" ref="ruleForm"
注1：有多个表单，怎么在提交进行区分？
我们在rules这里写了对表单的验证规则，但是我们如何在methods里进行指定的表单进行认证，
所以我们一开始就在el-form里写了 ref=“ruleForm”，我们在methods里就可以用
注2：清空表单验证信息
this.$refs[formName].resetFields();
3、新增功能
首先添加一个点击事件
<el-button size="small" type="primary" icon="el-icon-plus" @click="add">添加</el-button>
逻辑代码
closeDialog() {
this.editFormVisible = false;
this.clearForm();
},
submitForm() {
this.$refs['editForm'].validate((valid) => {
if (valid) {
let url;
if(this.editForm.id == 0){
url = this.axios.urls.SYSTEM_ARTICLE_ADD;
}else{
url = this.axios.urls.SYSTEM_ARTICLE_EDIT;
}
this.axios.post(url,
this.editForm
).then((response) => {
console.log(response);
this.clearForm();
this.doSearch(this.formInline);
}).catch((response) => {
console.log(response);
});
} else {
console.log('error submit!!');
return false;
}
});
},
clearForm(){
this.editForm.id = 0;
this.editForm.title = '';
this.editForm.body = '';
this.formInline.page = 1;
this.formInline.rows = 10;
this.editFormVisible = false;
},
add(){
this.title = '新增文章';
this.editFormVisible = true;
},
4、修改功能
<!-- 编辑界面 -->
<el-dialog :title="title" :visible.sync="editFormVisible" width="30%" @click="closeDialog">
<el-form label-width="120px" :model="editForm" :rules="rules" ref="editForm">
<el-form-item label="文章标题" prop="title">
<el-input size="small" v-model="editForm.title" auto-complete="off" placeholder="请输入文章标题"></el-input>
</el-form-item>
<el-form-item label="文章内容" prop="body">
<el-input size="small" v-model="editForm.body" auto-complete="off" placeholder="请输入文章内容"></el-input>
</el-form-item>
</el-form>
<div slot="footer" class="dialog-footer">
<el-button size="small" @click="closeDialog">取消</el-button>
<el-button size="small" type="primary" class="title" @click="submitForm">保存</el-button>
</div>
</el-dialog>
edit(index,row){
//
this.title = '编辑文章';
this.editForm.id = row.id;
this.editForm.title = row.title;
this.editForm.body = row.body;
this.editFormVisible = true;
},
5、删除功能
del(index,row){
let url = this.axios.urls.SYSTEM_ARTICLE_DEL;
this.axios.post(url, {
id: row.id
}).then((response) => {
console.log(response);
this.clearForm();
this.doSearch({});
}).catch((response) => {
console.log(response);
});
}
Article.vue里面所有代码
<template>
<div>
<!-- 搜索筛选 -->
<el-form :inline="true" :model="formInline" class="user-search">
<el-form-item label="搜索：">
<el-input size="small" v-model="formInline.title" placeholder="输入文章标题"></el-input>
</el-form-item>
<el-form-item>
<el-button size="small" type="primary" icon="el-icon-search" @click="search">搜索</el-button>
<el-button size="small" type="primary" icon="el-icon-plus" @click="add">添加</el-button>
</el-form-item>
</el-form>
<el-table size="small" :data="listData" border element-loading-text="拼命加载中">
<el-table-column prop="id" label="ID" width="300">
</el-table-column>
<el-table-column prop="title" label="文章标题" width="300">
</el-table-column>
<el-table-column prop="body" label="文章内容" width="300">
</el-table-column>
<el-table-column align="center" label="操作" min-width="300">
<template slot-scope="scope">
<el-button size="mini" @click="edit(scope.$index, scope.row)">编辑</el-button>
<el-button size="mini" type="danger" @click="del(scope.$index, scope.row)">删除</el-button>
</template>
</el-table-column>
</el-table>
<!-- 分页条 -->
<el-pagination style="margin-top: 20px;" @size-change="handleSizeChange" @current-change="handleCurrentChange"
:current-page="formInline.page" :page-sizes="[10, 20, 30, 50]" :page-size="formInline.rows" layout="total, sizes, prev, pager, next, jumper"
:total="total">
</el-pagination>
<!-- 编辑界面 -->
<el-dialog :title="title" :visible.sync="editFormVisible" width="30%" @click="closeDialog">
<el-form label-width="120px" :model="editForm" :rules="rules" ref="editForm">
