vue同个按钮控制展开和折叠同个事件操作

我就废话不多说了，大家还是直接看代码吧~

<el-button :icon="!moreshow?'el-icon-arrow-down':'el-icon-arrow-up'" @click="getmoreshow">{{!moreshow?更多:隐藏}}</el-button>

data() {
  return {
  moreshow:false,
  count:1,
  }
}

mounted() {
  this.getmoreshow()//避免点击两次才生效
},
methods: {
  getmoreshow(){
  if(this.count%2==0){
   this.moreshow=true
  }else{
   this.moreshow=false
  }
  this.count++
  },
}

补充知识：vue 可折叠面板的工作区组件

这个组件中使用了elementui的两个图标

组件Js：

Vue.component('work-container', {
  props: ['height'],
  data: function () {
    return {
      isCollapse: false
    }
  },
  computed: {
    topbarcssobj: function () {
      var obj = { padding: '3px' };
      if (this.isCollapse) {
        obj.display = 'none';
      }
      else {
        obj.display = 'block';
        if (this.height) {
          obj.height = this.height + 'px';
        } else {
          obj.height = '40px';
        }
      }
      return obj;
    },
    btniconcssobj: function () {
      return this.isCollapse ? 'el-icon-caret-bottom' : 'el-icon-caret-top';
    },
    strview: function () {
      return this.isCollapse ? '显示' : '隐藏';
    }
  },
  methods: {
    togglebar: function () {
      this.isCollapse = !this.isCollapse;
    }
  },
  template: '<el-container>\
          <el-header v-bind:style="topbarcssobj">\
          <slot name="tbar"></slot>\
          </el-header>\
          <el-main>\
          <div style="margin:3px;">\
            <div style="float:left;margin-right:10px;cursor:pointer;color: #d3dce6;display:none;" v-on:click="togglebar">\
              <i v-bind:class="btniconcssobj">{{strview}}查询条件</i>\
            </div>\
            <div>\
            <slot name="btn"></slot>\
            </div>\
          </div>\
          <div>\
            <slot name="work"></slot>\
          </div>\
          </el-main>\
         </el-container>'
});

调用：

<script src="~/Scripts/vue/workcontainer.js"></script>

 <work-container v-bind:height="80">
    <template v-slot:tbar>
      <spec-combo v-on:selectspec="setSpec"></spec-combo>
      <ban-input v-on:selectban="setBan"></ban-input>
      <grade-input v-on:selectban="setGrade"></grade-input>

    </template>
    <template v-slot:work>
      {{spec}}
      {{ban}}
      {{grade}}
    </template>
  </work-container>
