阶段5 3.微服务项目【学成在线】_day03 CMS页面管理开发_07-新增页面-前端-页面完善

在新增页面加返回按钮

 <el-button type="primary" @click="go_back" >返回</el-button>

go_back事件

　　　go_back(){
        this.router.push({
          path:'/cms/page/list'
        })
      }

点击新增页面的时候把当前的页面传过去，还有查询条件。

然后再点击返回的时候，还是跳转到刚才的页面

page_list.vue内rounter-link加上参数。

 　　<router-link class="mui-tab-item" :to="{path:'/cms/page/add/',query:{
      page: this.params.page,
      siteId: this.params.siteId}}">
        <el-button type="primary" size="small">新增页面</el-button>
      </router-link>

http://localhost:11000/#/cms/page/add/?page=3&siteId=5a751fab6abb5044e0d19ea1

点击返回参数回传。取当前路由的参数
 

　　methods:{
      addSubmit(){
        alert("提交")
      },
      go_back() {
        this.$router.push({
          path:'/cms/page/list',
          query:{
            page: this.$route.query.page,
            siteId: this.$route.query.siteId
          }
        })
      }
    }

点击返回把参数传回来了

参数带回来还要选中数据

在created里面处理参数，数据还没有渲染的时候进行处理

  created() {
      //取出路由中的参数，赋值给数据对象
      this.params.page=Number.parseInt(this.$route.query.page || 1)
      this.params.siteId=this.$route.query.siteId || ''
    }

返回的数据 默认选中下拉和刚才的页码
 

页码返回列表页 被选中 一定要绑定这属性值。:current-page="this.params.page"

表单校验

可以看下官方的文档：https://element.eleme.cn/#/zh-CN/component/form


首先在表单上添加表单的校验名称

 

:rules="pageFormRules"

这个名称对应json的对象，就是表单验证的规则

        pageFormRules: {
          siteId:[
            {required: true, message: '请选择站点', trigger: 'blur'}
          ],
          templateId:[
            {required: true, message: '请选择模版', trigger: 'blur'}
          ],
          pageName: [
            {required: true, message: '请输入页面名称', trigger: 'blur'}
          ],
          pageWebPath: [
            {required: true, message: '请输入访问路径', trigger: 'blur'}
          ],
          pagePhysicalPath: [
            {required: true, message: '请输入物理路径', trigger: 'blur'}
          ]
        }    

鼠标放在页面名称的文本框，然后鼠标再移动到别的地方 就会提示需要填写。

点击提交按钮 触发校验

表单需要加属性ref


 

addSubmit(){
  this.$refs['pageForm'].validate((valid)=>{
    if(valid){
      alert('submit!')
    }else{
      console.log('error submit!!')
      return false
}
  })
}

点击提交按钮 出发校验

数据都正确输入
