对页面 新增 修改 删除等按钮进行隐藏，添加自定义按钮

```
cruds() {
    return CRUD({
      title: '出库明细',
      url: 'api/pickDetail',
      idField: 'id',
      sort: 'id,desc',
      crudMethod: {...crudPickDetail},
      optShow: {
        add: true,
        edit: false,
        del: false,
        reset: true,
        download: true
      }
    })
  }
```

添加自定义按钮

[:disabled="show_fp” ]()为显示状态

[@click="allocate(crud.selections)"]()  为点击时间 [crud.selections]()  选中的数据

```
<el-button
          slot="right"
          class="filter-item"
          type="success"
          icon="el-icon-edit"
          size="mini"
          :disabled="show_fp"
          @click="allocate(crud.selections)"
        >
          分配
 </el-button>
```



```
data() {
    return {
      show_fp: true,
      show_jh: true,
      show_cancelfp:true,
      radio3: '全部',
      items: [],
      permission: {
        add: ['admin', 'pickDetail:add'],
        edit: ['admin', 'pickDetail:edit'],
        del: ['admin', 'pickDetail:del']
      },
      rules: {
        item: [
          {required: true, message: '物料必填', trigger: 'blur'}
        ]
      },
      queryTypeOptions: [
        {key: 'itemCode', display_name: '物料编码'},
        {key: 'itemName', display_name: '物料名称'},
        {key: 'po', display_name: '任务号'},
        {key: 'status', display_name: '状态'}
      ]
    }
  }
```

```
allocate(datas) {
      this.$confirm(`选中的${datas.length}条数据分配确认?`, '提示', {
        confirmButtonText: '确定',
        cancelButtonText: '取消',
        type: 'warning'
      }).then(() => {

        const ids = [];
        for (let i = 0; i < datas.length; i++) {
          ids.push(datas[i].id)
        }
        crudPickDetail.allocate(ids).then(res => {
          DonMessage.success('分配成功！')
          this.crud.toQuery();
        }).catch(() => {

        })

      }).catch(() => {
        this.$refs.table.clearSelection()
        DonMessage.info('取消成功！')
      });
    }
```

修改选择框选中事件 [@selection-change="selectionChangeHandlerTwo"]()  

```
  <el-table ref="table" v-loading="crud.loading" :data="crud.data" size="small"
                style="width: 100%;"

                height="58vh"
                @selection-change="selectionChangeHandlerTwo">
```

根据选择的数据进行判断，新加的按钮是否可用

```
 selectionChangeHandlerTwo(val) {
      this.crud.selections = val
      if (this.crud.selections.length > 1 || this.crud.selections.length == 0) {
        this.show_jh = true;
        this.show_fp = true;
        this.show_cancelfp=true;
      }

      //分配
      if (this.crud.selections.length == 1 && this.crud.selections[0].orderQty > this.crud.selections[0].allocatedQty) {
        this.show_jh = true;
        this.show_fp = false;
      }

      //取消分配
      if (this.crud.selections.length == 1 && this.crud.selections[0].orderQty == this.crud.selections[0].allocatedQty&&this.crud.selections[0].pickedQty==0) {
        this.show_jh = true;
        this.show_fp = true;
        this.show_cancelfp=false;
      }

      //拣货
      if (this.crud.selections.length == 1 && this.crud.selections[0].orderQty == this.crud.selections[0].allocatedQty) {
        this.show_jh = false;
        this.show_fp = true;
      }


    }
```
