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">

                      class="name-wrapper"
                    >

                      >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。
