1.表单验证
2.增删改功能实现
一、表单验证
1.导入相关代码
<!-- 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="部门名称" prop="deptName">
<el-input size="small" v-model="editForm.deptName" auto-complete="off" placeholder="请输入部门名称"></el-input>
</el-form-item>
<el-form-item label="部门代码" prop="deptNo">
<el-input size="small" v-model="editForm.deptNo" auto-complete="off" placeholder="请输入部门代码"></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" :loading="loading" class="title" @click="submitForm('editForm')">保存</el-button>
</div>
</el-dialog>
2、 表单验证
①、把rules加到from控件里面(定义属性)
②、rules定义规则
③、调用规则
<script>
export default {
name: ‘Articles’,
data() {
return {
listData: [],
title: ”,
editFormVisible: false,
formInline: {
page: 1,
rows: 10,
total: 0,
title: ”
},
editForm: {},
rules: {
title: [{
required: true,
message: ‘请输入文章标题’,
trigger: ‘blur’
},
{
min: 3,
max: 5,
message: ‘长度在 3 到 5 个字符’,
trigger: ‘blur’
}
],
body: [{
required: true,
message: ‘请输入文章内容’,
trigger: ‘blur’}]
}
}
},
methods: {
handleSizeChange(rows) {
console.log(“当前页查询数据量” + rows)
this.formInline.page = 1;
this.formInline.rows = rows;
this.search();
},
handleCurrentChange(page) {
console.log(“当前页为” + page)
this.formInline.page = page;
this.search();
},
closeDialog() {},
handleEdit() {
this.editFormVisible = true;
},表单提交
submitForm(formName) {
this.$refs[formName].validate((valid) => {
if (valid) {
alert(‘submit!’);
} else {
console.log(‘error submit!!’);
return false;
}
});
},
doSearch(param) {
let url = this.axios.urls.SYSTEM_ARTICLE_LIST;
this.axios.post(url, param).then((resp) => {
console.log(resp);
this.listData = resp.data.result;
this.formInline.total = resp.data.pageBean.total;
}).catch(function(error) {
console.log(error);
});
//箭头函数解决了This指针污染问题
this.$root.Bus.$on(“collapsed-aside”, (v) => {
this.collapsed = v;
});
},
search() {
this.doSearch(this.formInline);
}
},
created() {
this.doSearch({});
}
}
</script>
3、展示页面
①、点击添加按钮
②、表单验证
二、增删改功能实现
1、导入相关代码(或者从element官网中找到相关组件)
<template>
<div>
<!-- 这是文章列表组件 -->
<!-- 搜索筛选 -->
<el-form :inline="true" :model="formInline" class="user-search">
<el-form-item label="搜索:">
<el-input size="small" v-model="formInline.title" placeholder="文章标题"></el-input>
</el-form-item>
<el-form-item>
<el-button size="small" type="primary" icon="el-icon-search" @click="search">搜索</el-button>
<el-button size="small" type="primary" icon="el-icon-plus" @click="handleEdit()">添加</el-button>
</el-form-item>
</el-form>
<!--列表-->
<el-table size="small" :data="listData" highlight-current-row border element-loading-text="拼命加载中" style="width: 100%;">
<el-table-column align="center" type="selection" width="60">
</el-table-column>
<el-table-column sortable prop="id" label="文章ID" width="300">
</el-table-column>
<el-table-column sortable prop="title" label="文章标题" width="300">
</el-table-column>
<el-table-column sortable prop="body" label="文章内容" width="300">
</el-table-column>
<el-table-column align="center" label="操作" min-width="300">
<template slot-scope="scope">
<el-button size="mini" @click="handleEdit(scope.$index, scope.row)">编辑</el-button>
<el-button size="mini" type="danger" @click="deleteUser(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="100" layout="total, sizes, prev, pager, next, jumper"
:total="formInline.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="请输入部门名称"></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="请输入部门代码"></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('editForm')">保存</el-button>
</div>
</el-dialog>
</div>
</template>
2、定义方法
<script>
export default {
name: ‘Articles’,
data() {
return {
listData: [],
title: ”,
editFormVisible: false,
formInline: {
page: 1,
rows: 10,
total: 0,
title: ”
},
editForm: {数据回显
title: ”,
body: ”,
id: 0
},
rules: {
title: [{
required: true,
message: ‘请输入文章标题’,
trigger: ‘blur’
},
{
min: 3,
max: 5,
message: ‘长度在 3 到 5 个字符’,
trigger: ‘blur’
}
],
body: [{
required: true,
message: ‘请输入文章内容’,
trigger: ‘blur’}]
}
}
},
methods: {
handleSizeChange(rows) {
console.log(“当前页查询数据量” + rows)
this.formInline.page = 1;
this.formInline.rows = rows;
this.search();
},
handleCurrentChange(page) {
console.log(“当前页为” + page)
this.formInline.page = page;
this.search();
},
clearData() {清空数据
this.editFormVisible = false;
this.title = ”;
this.editForm.id = 0;
this.editForm.title = ”;
this.editForm.body = ”;
},
closeDialog() {窗体关闭事件
this.clearData();
},
handleEdit(index, row) {新增方法
this.clearData();
this.editFormVisible = true;
if (row) {
this.title = ‘编辑窗口’;
this.editForm.id = row.id;
this.editForm.title = row.title;
this.editForm.body = row.body;
} else {
this.title = ‘新增窗口’;
}
},
deleteUser(index, row) {删除方法,获取一个id
this.editForm.id=row.id;
let url = this.axios.urls.SYSTEM_ARTICLE_DEL;
this.axios.post(url, this.editForm).then((resp) => {
console.log(resp);
this.clearData();
this.search();
}).catch(function(error) {
console.log(error);
});
},
submitForm(formName) {表单提交
this.$refs[formName].validate((valid) => {
if (valid) {
let url;
if (this.editForm.id == 0) {判断是新增还是删除
url = this.axios.urls.SYSTEM_ARTICLE_ADD;
} else {
url = this.axios.urls.SYSTEM_ARTICLE_EDIT;
}
this.axios.post(url, this.editForm).then((resp) => {
console.log(resp);
this.clearData();
this.search();
}).catch(function(error) {
console.log(error);
});} else {
console.log(‘error submit!!’);
return false;
}
});
},
doSearch(param) {
let url = this.axios.urls.SYSTEM_ARTICLE_LIST;
this.axios.post(url, param).then((resp) => {
console.log(resp);
this.listData = resp.data.result;
this.formInline.total = resp.data.pageBean.total;
}).catch(function(error) {
console.log(error);
});
//箭头函数解决了This指针污染问题
this.$root.Bus.$on(“collapsed-aside”, (v) => {
this.collapsed = v;
});
},
search() {
this.doSearch(this.formInline);
}
},
created() {
this.doSearch({});
}
}
</script>
结果展示
①新增
② 修改
③ 删除(注意上图的数据为157条)
现在为156条,删除成功
结束了,掰掰~
