<template slot-scope="scope"> <el-select disabled clearable filterable v-model="scope.row.goods_id" v-if="merchandiseNameData.length > 0" :virtual-scroll="{ itemHeight: 40, approxItemCount: 50 }"> <el-option v-for="goods in merchandiseNameData" :key="goods.data" :label="goods.texture" :value="goods.data"> </el-option> </el-select> </template>不使用for循环

上述代码中使用了`v-for`指令来循环生成`el-option`选项。如果不想使用`v-for`循环,可以使用`computed`属性来过滤、排序、处理数据,并在模板中使用`v-if`条件渲染来生成选项。示例代码如下:
```
<template slot-scope="scope">
<el-select disabled clearable filterable v-model="scope.row.goods_id"
v-if="filteredOptions.length > 0" :virtual-scroll="{ itemHeight: 40, approxItemCount: 50 }">
<el-option v-for="goods in filteredOptions" :key="goods.data" :label="goods.texture"
:value="goods.data">
</el-option>
</el-select>
</template>
<script>
export default {
// ...
computed: {
filteredOptions() {
const data = this.merchandiseNameData;
// 过滤、排序、处理数据
const filteredData = data.filter(goods => goods.xxx === 'xxx')
.sort((a, b) => a.xxx - b.xxx)
.map(goods => { xxx });
return filteredData;
}
}
}
</script>
```
其中,`filteredOptions`是一个计算属性,用于过滤、排序、处理数据,并返回处理后的选项数组。在模板中使用`v-if`条件渲染来检查选项数组是否为空,如果不为空,则显示`el-select`下拉框和选项。需要注意的是,上述代码只是示例,具体计算属性的实现需要根据业务需求进行修改。
