第十二章 增删改查
这章我们来做用户的增删改查
查询
先来查，在上面另一个查询条件，用来查询用户姓名及用户名的查询
在查询按钮前添加个文本框，并使用col来进行布局，先不管好不好看。
<el-input v-model="s_user" placeholder="用户名或姓名"></el-input>
因为添加了v-model=s_user了，所以我们需要在data()里添加s_user:””来绑定，并在queryList方法中的参数添加username:this.s_user。我们打开浏览器f12来查看看一下查询时的参数，发现已经发送到后台了。
1 <el-row > 2 <el-col :span="6"> 3 <el-input v-model="s_user" placeholder="用户名或姓名"></el-input> 4 </el-col> 5 <el-col :span="6"> 6 <el-button type="primary" size="small" id="search" @click="search">查询</el-button> 7 </el-col> 8 </el-row>
1 return { 2 loading: true, 3 tableData: [], 4 s_user:"", 5 pagination: { 6 pageSizes: [1, 10, 20, 50], 7 currentPage: 1, 8 total: 0, 9 pageSize: 10, 10 }, 11 }
let para = {
pageNum: this.pagination.currentPage,
pageSize: this.pagination.pageSize,
username: this.s_user,
};
接下来我们改造一下后台
UserController中找到方法queryUser。我们当初已经预留查询参数的对象QueryUser了。现在我们需要添加两个username及realname，这样前台传来的参数自动就会加载到username，然后我们在controller中再处理一下将username的值赋值给realname；然后我们需要打开xml文件了，添加相关的查询，使用if来判断，使用bind来防止注入攻击
QueryUser.java
1 private String username; 2 3 public String getUsername() { 4 return username; 5 } 6 7 public void setUsername(String username) { 8 this.username = username; 9 }
UserMapper.xml
1 <select id="select" resultMap="UserResultMap"> 2 select 3 <include refid="columns"/> 4 from ts_user 5 where 1 = 1 6 <if test="username != null and username != ''"> 7 <bind name="bName" value="'%'+username+'%'"/> 8 and (username like #{bName} 9 or realname like #{bName}) 10 </if> 11 </select>
好了。我们成功完成了查询。如果需要查询其它的，重复我们这个过程就可以了。
新增
下面是新增我们打开element-ui的网站，找到组件，我们使用Dialog对话框来实现弹窗实现新增功能。我们实现网站demo中的自定义里第二个打开嵌套表彰的dialog来做最初的代码。
我们只把重要的，有我们有关的代码，贴进来并且不做任选修改。效果如下，点击打开嵌套表单的Dialog即可实现的弹窗效果。
然后我们在这基本上，进行修改，可以参加form表单，及你用到的控件等。我们完成，界面绘制，及必填验证
首先，form上添加ref用来验证时调用。
必填是使用:rules=”rules”来完成的。并且在需要验证的控件添加prop=”username”，然后在data中，添加相应的代码
1 rules: { 2 username: [ 3 { required: true, message: '请输入用户名', trigger: 'blur' }, 4 { min: 5, max: 20, message: '长度在 5 到 20 个字符', trigger: 'blur' } 5 ], 6 realname: [ 7 { required: true, message: '请输入姓名', trigger: 'blur' }, 8 { min: 1, max: 20, message: '长度在 1 到 20 个字符', trigger: 'blur' } 9 ], 10 },
添加一个saveAdd的方法，当我们什么也不写时，提示我们必填，当我们填写上了，提示我们submit。
1 saveAdd:function(){ 2 var _this = this; 3 this.$refs["formAdd"].validate(valid => { 4 if(valid){ 5 alert("submit!") }else{ 6 return false; 7 } 8 }); 9 },
然后我们调用后台的代码补充完整，添加btnLoading用于提交时，将按钮设置成loading状态，防止重复提交。代码见最后
然后我们完善后台代码。需要注意的是，表中的不能为null的字段，在insert时都要有值。哪怕是个空格也不能是null。
然后就是，username是有唯一键的，所以在insert前，我们需要查询一下，是否存在，如果存在也要将结果返回到前端。如果唯一键不处理前台接到的错误就是500，所以我们还不能偷懒，只能自己写个查询。然后我们之前用于查询的username需要修改为user，专门用来查询，将username空出来用于用户名查询。中间需要进行改造。我们还添加了RecordExistenceException用于专门对记录存在的扔出异常来。
然后，密码和盐这块这次没写，留到下次。
相关，修改是最简单的，用户名不能修改。
删除也是逻辑删除，将状态变更为停用即可。
后台代码会在本章最后一次放出。
我们再回到前端，按钮必为新增。然后，进行一下操作。完美，新增完，自动刷新。再次打开新增时，就发现问题，上次输入的记录没清。那就再添加一下清空的方法。
_this.$refs["formAdd"].resetFields();
修改和删除
新增到现在就完成了。下面是修改和删除
先在列表中添加操作列
1 <el-table-column label="操作" width="100"> 2 <template slot-scope="scope"> 3 <span> 4 <el-button type="text" size="small" v-on:click="edit(scope.row)" icon="edit">编 辑</el-button> 5 <el-button type="text" size="small" v-on:click="del(scope.row)" icon="delete">删 除</el-button> 6 </span> 7 </template> 8 </el-table-column>
添加编辑和删除的方法，测试一下。好用
del:function(row){
alert("del"+row.id);
},
edit:function(row){
alert("edit"+row.id);
},
删除
删除简单，我们先写删除，需要一个确认框，进行删除的二次确认，再调用后台即可。
1 let _this = this; 2 this.$confirm('将删除用名['+row.username+'], 是否继续?', '提示', { 3 confirmButtonText: '确定', 4 cancelButtonText: '取消', 5 type: 'warning' 6 }).then(() => { 7 let delUrl = "/api/user/del"; 8 let param ={ 9 id:row.id, 10 }; 11 Vue.axios.post(delUrl,param) 12 .then(function (res) { 13 _this.btnLoading = false; 14 if (res.status === 200) { 15 let result = res.data; 16 if (result.success) { 17 _this.$message({ 18 type: 'success', 19 message: '删除成功!' 20 }); 21 _this.queryList(); 22 } else { 23 _this.$message({ 24 message: result.message, 25 type: "error", 26 }) 27 } 28 } else { 29 _this.$message({ 30 message: res.message, 31 type: "error", 32 }) 33 } 34 }); 35 .catch(function (error) { 36 _this.btnLoading = false; 37 _this.$message({ 38 message: "发生错误" + error, 39 type: "error", 40 }); 41 }); 42 });
完美。
在列表中我们看到状态是3的记录了，表示已经被删除了。但是前的按钮不好看。我们在按钮里添加代码
v-show="scope.row.status!='3'"
然后，我们再看。好了没有了
修改
我们先将修改的form，复制一份，formAdd变为formEdit，同时，将data里的也添加formEdit，还有dialogFormEditVisible，添加一个
然后，在edit的方法里，添加 this.dialogFormEditVisible = true; 就能看到效果了。Username是不能修改的，所以设为不可修改，添加id只读。更新时以id为主
下一步就是把数据添加上了，再有个保存，就完成了。为了保证每次修改都是最新的，所以点修改时，都要去后台实时获取新数据，而不是使用list中的数据，以用来保证数据的准确性。
添加查询的语句
1 let _this = this; 2 let editUrl = "/api/user/get"; 3 let param = { 4 id: row.id, 5 } 6 Vue.axios.post(editUrl, param) 7 .then(function (res) { 8 _this.loading = false; 9 if (res.status === 200) { 10 let result = res.data; 11 if (result.success) { 12 _this.dialogFormEditVisible = true; 13 _this.formEdit.id = result.data.id; 14 _this.formEdit.username = result.data.username; 15 _this.formEdit.realname = result.data.realname; 16 _this.formEdit.mail = result.data.mail; 17 _this.formEdit.sex = result.data.sex; 18 _this.formEdit.phone = result.data.phone; 19 _this.formEdit.remarks = result.data.remarks; 20 } else { 21 _this.$message({ 22 message: result.message, 23 type: "error", 24 }); 25 } 26 } else { 27 _this.$message({ 28 message: res.message, 29 type: "error", 30 }); 31 } 32 }) 33 .catch(function (error) { 34 _this.$message({ 35 message: "发生错误" + error, 36 type: "error", 37 }) 38 });
添加保存方法。
1 var _this = this; 2 this.$refs["formEdit"].validate(valid => { 3 if (valid) { 4 let param = { 5 id: this.formEdit.id, 6 username: this.formEdit.username, 7 realname: this.formEdit.realname, 8 phone: this.formEdit.phone, 9 sex: this.formEdit.sex, 10 mail: this.formEdit.mail, 11 remarks: this.formEdit.remarks, 12 } 13 _this.btnLoading = true; 14 var addUrl = "/api/user/edit"; 15 Vue.axios.post(addUrl, param) 16 .then(function (res) { 17 _this.btnLoading = false; 18 if (res.status === 200) { 19 let result = res.data; 20 if (result.success) { 21 _this.$message({ 22 message: "保存成功", 23 type: "success", 24 }); 25 _this.dialogFormEditVisible = false; 26 _this.queryList(); 27 } else { 28 _this.$message({ 29 message: result.message, 30 type: "error", 31 }) 32 } 33 } else { 34 _this.$message({ 35 message: res.message, 36 type: "error", 37 }) 38 } 39 }) 40 .catch(function (error) { 41 _this.btnLoading = false; 42 _this.$message({ 43 message: "发生错误" + error, 44 type: "error", 45 }); 46 }); 47 } else { 48 return false; 49 } 50 });
完成。我们现在可以整体，再测试一下。发现个问题，新增、修改的弹出，我们再点遮罩层和按esc时都会关闭。我们并不希望这样。看了看官方文档，设两个属性为false即可。close-on-click-modal，close-on-press-escape。翻页也挺好用。本章完成。以下是相关页面代码
