总结
一、ElementUI增加,删除,修改的实现
1.前期的准备工作 1.1引入相应的接口
'BOOK_ADD': '/book/addBook', //书籍添加
'BOOK_EDIT': '/book/editBook', //书籍修改
'BOOK_DEL': '/book/delBook', //书籍删除
1.2按钮的添加
1.3新增弹出框
1.4在data中添加数据
data() {
return {
bookname: '',
tableData: [],
page: 1,
rows: 10,
total: 0,
title: '新增窗体',
dialogFormVisible: false,
booktypes: [{
id: 1,
name: '言情'
}, {
id: 2,
name: '玄幻'
}, {
id: 3,
name: '武侠'
}],
formLabelWidth: '100px',
book: {
id: '',
bookname: '',
price: '',
booktype: ''
},
rules: {
bookname: [{
required: true,
message: '请输入书籍名称',
trigger: 'blur'
},
{
min: 5,
max: 12,
message: '长度在 5 到 12 个字符',
trigger: 'blur'
}
],
price: [{
required: true,
message: '请输入书籍价格',
trigger: 'blur'
}],
booktype: [{
required: true,
message: '请输入书籍类型',
trigger: 'blur'
}]
}
}
}
1.5在methods中添加方法
doSubmit() {
//新增或者编辑到提交后台的方法
let url = this.axios.urls.BOOK_ADD;
if (this.title == '编辑窗体') {
url = this.axios.urls.BOOK_EDIT;
}
let params = {
id: this.book.id,
bookname: this.book.bookname,
price: this.book.price,
booktype: this.book.booktype
}
this.$refs['book'].validate((valid) => {
if (valid) {
this.axios.post(url, params).then(resp => {
console.log(resp);
if (resp.data.success) {
this.$message({
message: resp.data.msg,
type: 'success'
});
this.clear();
this.query({});
} else {
this.$message({
message: resp.data.msg,
type: 'error'
});
}
}).catch(err => {})
} else {
console.log('error submit!!');
return false;
}
});
},
clear() {
this.dialogFormVisible = false;
this.book = {
id: '',
bookname: '',
price: '',
booktype: ''
};
},
open(idx, row) {
this.dialogFormVisible = true;
if (row) {
this.title = '编辑窗体';
this.book.id = row.id;
this.book.bookname = row.bookname;
this.book.price = row.price;
this.book.booktype = row.booktype;
}
}
运行效果:
书籍的修改: 2.1在ElementUI找自己想用的组件
2.2.methods中添加方法
open(idx, row) { this.dialogFormVisible = true; if (row) { this.title = ‘编辑窗体’; this.book.id = row.id; this.book.bookname = row.bookname; this.book.price = row.price; this.book.booktype = row.booktype; } }
let url = this.axios.urls.BOOK_ADD;
if (this.title == '编辑窗体') {
url = this.axios.urls.BOOK_EDIT;
}
let params = {
id: this.book.id,
bookname: this.book.bookname,
price: this.book.price,
booktype: this.book.booktype
}
this.axios.post(url, params).then(resp => {
console.log(resp);
if (resp.data.success) {
this.$message({
message: resp.data.msg,
type: 'success'
});
this.clear();
this.query({});
} else {
this.$message({
message: resp.data.msg,
type: 'error'
});
}
}).catch(err => {})
运行结果:
3.删除书籍功能
del(idx, row) {
this.$confirm('您确定删除id为' + row.id + '的书籍吗?', '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(resp => {
if (resp.data.success) {
this.$message({
message: resp.data.msg,
type: 'success'
});
this.clear();
let params = {
bookname: this.bookname
}
this.query(params);
} else {
this.$message({
message: resp.data.msg,
type: 'error'
})
}
})
}).catch(() => {
this.$message({
type: 'info',
message: '已取消删除'
});
});
},
运行结果:
二、表单的验证
1.修改弹出框
2.在data修改对应的参数,根据ElementUI官方文档
rules: {
bookname: [{
required: true,
message: '请输入书籍名称',
trigger: 'blur'
},
{
min: 5,
max: 12,
message: '长度在 5 到 12 个字符',
trigger: 'blur'
}
],
price: [{
required: true,
message: '请输入书籍价格',
trigger: 'blur'
}],
booktype: [{
required: true,
message: '请输入书籍类型',
trigger: 'blur'
}]
}
运行结果:
