一.实现CRUD
配置路由接口，用于向后端请求数据
'BOOK_Add': '/book/addBook', //绑定书籍'BOOK_UPD': '/book/editBook', //绑定书籍'BOOK_DEL': '/book/delBook', //绑定书籍前端编写以及弹出层

</template>注意
注1：隐藏显示设置，通过Vue实例对象中的dialogFormVisible="true|false"来控制dialog显示隐藏
:visible.sync="dialogFormVisible"
注2：通过close或closed事件，在关闭dialog弹出框时清空form表单数据和验证信息；
@close="dialogClose"
增加删除修改功能，以及表单验证的实现
<script>export default {data() {return {bookname: '',tableData: [],rows: 10,page: 1,total: 0,title: '新增',dialogFormVisible: false,formLabelWidth: '100px',types: [],book: {id: '',bookname: '',price: '',booktype: ''},rules: {bookname: [{required: true,message: '请输入书籍名称',trigger: 'blur'},{min: 1,max: 5,message: '长度在 1到 5 个字符',trigger: 'blur'}],price: [{required: true,message: '请输入价格',trigger: 'blur'}],booktype: [{required: true,message: '请输入类型',trigger: 'blur'}]}}},methods: {del(idx, row) {this.$confirm('此操作将永久删除id为' + row.id + ',是否继续?', '提示', {confirmButtonText: '确定',cancelButtonText: '取消',type: 'warning'}).then(() => {let url = this.axios.urls.BOOK_DEL;this.axios.post(url, {id: row.id}).then(r => {console.log(r);this.$message({type: 'success',message: '删除成功!'});this.query({});}).catch(e => {})}).catch(() => {this.$message({type: 'info',message: '已取消删除'});});},dosub() {this.$refs['book'].validate((valid) => {if (valid) {let url = this.axios.urls.BOOK_ADD;//获得动态数据if (this.title = '编辑') {url = this.axios.urls.BOOK_UPD;}let params = {id: this.book.id,bookname: this.book.bookname,price: this.book.price,booktype: this.book.booktype}this.axios.post(url, this.book).then(r => {console.log(r);this.clear();this.query({});}).catch(e => {})} else {console.log('error submit!!');return false;}});},//初始化窗体clear() {this.dialogFormVisible = false;this.title = '新增',this.book = {id: '',bookname: '',price: '',booktype: ''}},//打开窗体的方法open(idx, row) {this.dialogFormVisible = true;if (row) {this.title = '编辑';this.book.id = row.id;this.book.bookname = row.bookname;this.book.price = row.price;this.book.booktype = row.booktype;}},query(params) {//获得动态数据let url = this.axios.urls.BOOK_LIST;this.axios.get(url, {params: params}).then(r => {console.log(r);this.tableData = r.data.rows;this.total = r.data.total;}).catch(e => {})},onSubmit() {let params = {bookname: this.bookname}this.query(params);},handleSizeChange(r) {let params = {bookname: this.bookname,rows: r,page: this.page}this.query(params);},handleCurrentChange(p) {let params = {bookname: this.bookname,rows: this.rows,page: p}this.query(params);}},created() {this.query({});this.types = [{id: 1,name: '爱情'},{id: 2,name: '修仙'},{id: 3,name: '古装'},{id: 4,name: '校园'}];}}
