Vue_10_Spa_项目4次-CRUD+表单验证

本文主要是介绍Vue_10_Spa_项目4次-CRUD+表单验证，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

一、表单验证

在分页条下面放入编辑组件el-dialog：

 <!-- 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('editForm')">保存</el-button>
      </div>
    </el-dialog>

在script的date里面写入：

 rules: {
          title: [{
              required: true,
              message: '请输入文章标题',
              trigger: 'blur' /* trigger：触发器 */ /*blur失去焦点的时候触发  */
            },
            {
              /* 非空验证 */
              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: 'change'
          }]
        }

写入新增方法：

 handleEdit(){//新增
        this.editFormVisible =true;
      },

校验方法：

submitForm(formName) { //校验方法
        this.$refs[formName].validate((valid) => {
          if (valid) {
            alert('submit!');
          } else {
            console.log('error submit!!');
            return false;
          }
        });
      },

二、增删改功能实现

先把之前注释了的操作按钮放开：

 <el-table-column align="center" label="操作" min-width="2">
        <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>

定义回显：

editForm: {/* 定义回显 */
          title:'',
          body:'',
          id:0
        },

以及编辑窗口：

handleEdit() { //新增
        this.editFormVisible = true;
        // console.log(row);
        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';
        }
      },

实现点击修改也能弹出文本窗口有数据回显：

handleEdit(index,row) { //新增
        this.clearData();
        this.editFormVisible = true;
        // console.log(row);
        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';
        }
      },

校验新增与修改：

submitForm(formName) { //校验方法
        this.$refs[formName].validate((valid) => {
          if (valid) {
            let url;
            if(this.editForm.id == 0){
                url=this.axios.urls.SYSTEM_ARTICLE_ADD;//新增
            }else{
                url=this.axios.urls.SYSTEM_ARTICLE_EDIT;//修改
            }
            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;
          }
        });
      },

注：图片在尾部

删除方法：

deleteUser(index,row){
        this.editForm.id = row.id;
        let url=this.axios.urls.SYSTEM_ARTICLE_DEL;//删除
        this.axios.post(url, this.editForm).then((resp) =>{
          console.log(resp);
          this.clearData();
          this.search();
        }).catch(function(error) {
          console.log(error);
        });
      },

注：图片在尾部
