用query传参实现跳转效果
vue中已element-ui为例,写带参跳转很方便
<el-table :data="tables" style="width: 100%; cursor: pointer" :class="tableData.length > 0 ? '' : 'casesList'" :cell-style="{'text-align':'center'}" :header-cell-style="{'text-align':'center'}" > <el-button slot="empty" style="margin: 25% auto" type="primary" round @click="Newcase" >新建案件+</el-button > <el-table-column align="center" label="序号" width="80" type="index"> </el-table-column> <el-table-column label="案件名称" align="center"> <template slot-scope="scope"> <div @click="detailed(scope.row)" slot="reference" class="name-wrapper" > <el-tag size="medium">{{ scope.row.name }}</el-tag> </div> </template> </el-table-column> <el-table-column label="案件说明" align="center"> <template slot-scope="scope"> <span style="margin-left: 10px">{{ scope.row.description }}</span> </template> </el-table-column> <el-table-column label="案件类型" align="center"> <template slot-scope="scope"> <span style="margin-left: 10px">{{ scope.row.caseType }}</span> </template> </el-table-column> <el-table-column label="创建人" align="center"> <template slot-scope="scope"> <span style="margin-left: 10px">{{ scope.row.createUserName }}</span> </template> </el-table-column> <el-table-column label="创建时间" width="200" align="center"> <template slot-scope="scope"> <span style="margin-left: 10px">{{ scope.row.createTime }}</span> </template> </el-table-column> <el-table-column label="更新时间" width="200" align="center"> <template slot-scope="scope"> <span style="margin-left: 10px">{{ scope.row.modifiedTime }}</span> </template> </el-table-column> <el-table-column label="操作" width="300" align="center"> <template slot-scope="scope"> <el-button size="mini" @click="handleEdit(scope.$index, scope.row)" >修改</el-button > <el-button size="mini" type="danger" @click="handleDelete(scope.$index, scope.row)" >删除</el-button > <el-button size="mini" @click="handleJump(scope.$index, scope.row)" >分析</el-button > </template> </el-table-column> </el-table>
用后台接口取到数据渲染到页面,element-ui很方便配合它自己封装的handleJump(scope.$index, scope.row),就可以很轻松的找到你想要的值和精准的操作每一行。
<script> export default { components: {}, data() { return {}; }, //计算 computed: {}, //监听 watch: {}, methods: { handleJump(index, row) { console.log(index, row); console.log(row.id); this.$router.push({ path: "/CaseQueryCanvas", query: {data:row }, }); }, }, //方法 mounted() {}, }; </script>
这里我是已传对象的形式进行传值的,到跳转页面取值会比较方便,以免到跳转页面还需要截取自己所需的值,比较麻烦。
其中的path是需要传值的目的地,就是要将值传到此页面,此路径在
query就是你所要传递的对象。
接下来就是去目的地页面接收所传过去的参数
这里我只需要用传过去的ID去查找和跳转对应的页面,name属性去显示在当前页面上,所以用对象传值很方便,需要哪一个取哪一个即可。
这里就只取了传过来的ID,将id赋值给所需对象传参跳转相应页面即可。
而刚刚所说的name属性就被我用来显示,拿出来直接用就行
这样就完成了传值和动态显示,下面上完整代码,是自己所写的真实项目,写的有点垃圾大家只看query传参的部分就行。

vue使用query传参,解决跳转回退无参数渲染页面,无内容的方法(不需使用缓存的技术)
this.$router.push({ name: "goodsDetail", query: { id: id, goods_type:goods_type } });
mounted(){ this.proId = this.$route.query.id;//商品id this.goods_type = this.$route.query.goods_type;//商品类型 }
简说params和query的区别
params对象会在回退后消失,但是query会绑在路由后,有路可退
以上为个人经验,希望能给大家一个参考,也希望大家多多支持阿兔在线工具。
