How vue Click events change vuale? in button

after the data is successfully requested when clicking button, you need to change the value in button. You need to change the value of value through this.$refs and cooperate with the this.$nexttick event, but it has no effect. 

<el-table-column label="" width="100">
    <template slot-scope="scope">
        <button ref="releaseStatus" class="detach_btn" @click.prevent="issuePatrolPlan(scope.$index, scope.row)"></button>
    </template>
</el-table-column>

    // 
    issuePatrolPlan(index, row) {
      this.$confirm("", {
        confirmButtonText: "",
        cancelButtonText: "",
        type: "warning"
      }).then(() => {
        this.$http.put(this.$api.planPublish + row.id).then(res => {
          this.initPatrolPlan();
          this.$message({
            type: "success",
            message: "!"
          });
            console.log("row", row);
            // buttonvalue
            row.published == ""
              ? (this.$refs.releaseStatus.innerText = "")
              : (this.$refs.releaseStatus.innerText = "");
              console.log("this.$refs.releaseStatus.innerText", this.$refs.releaseStatus.innerText);
          // 
          this.initPatrolPlan();
        });
      });
    },

can't you just make the value of button a variable?

ref is written in a loop, so ref is always the last reference to button

try this 

<el-table-column label="" width="100">
    <template slot-scope="scope">
        <button :ref="'releaseStatus' + scope.$index" class="detach_btn" @click.prevent="issuePatrolPlan(scope.$index, scope.row)"></button>
    </template>
</el-table-column>

    // 
    issuePatrolPlan(index, row) {
      this.$confirm("", {
        confirmButtonText: "",
        cancelButtonText: "",
        type: "warning"
      }).then(() => {
        this.$http.put(this.$api.planPublish + row.id).then(res => {
          this.initPatrolPlan();
          this.$message({
            type: "success",
            message: "!"
          });
            console.log("row", row);
            // buttonvalue
            row.published == ""
              ? (this.$refs['releaseStatus' + index].innerText = "")
              : (this.$refs['releaseStatus' + index].innerText = "");
              console.log('this.$refs.releaseStatus.innerText', this.$refs.releaseStatus.innerText);
          // 
          this.initPatrolPlan();
        });
      });
    },
There are so many button, on the

page. Which one do you mean by this releaseStatus? it's random at all. It's just a template.
now that I use vue, I follow the principle of vue and modify the page by modifying the data. When the record is released, just set the published of row to true, and reset list (don't worry about performance, vue will compare the rendering tree by itself) 

<template slot-scope="scope">
    <button class="detach_btn">{{scope.row.published ? '' : ''}}</button>
  </template>
<button ref="'releaseStatus' + scope.$index" class="detach_btn" @click.prevent="issuePatrolPlan(scope.$index, scope.row)">{{scope.row.published == "" ? '' : ''}}</button>
