uni-app v-for循环 click无法传参解决方案

场景：循环后端数据数据控制子级是否显示

<view :class="['inspect-item-wrap', !item.show ? 'collapse': '']" v-for="item in list_arr.attribute_values" :key="item.id">
	<view class="item-show-wrap" @click="collapse(item)">
		<text class="item-title">{{item.name}}</text>
		<!-- <text class="item-tips ml-8">(多选)</text> -->
		<view class="arrow-bottom">
			<image src="../../static/detail/arrow-bottom.png" mode="widthFix"></image>
		</view>
	</view>
	<view class="item-hide-wrap">
		<view :class="['item-checkbox-wrap',isCheck(sonItem) ? 'active':''] " v-for="sonItem in item.option" :key="sonItem.sku"
			@click="checkbox(sonItem)">
			{{sonItem.value}}
		</view>
		<!-- <view class="item-checkbox-wrap">屏幕明显划痕</view>
		<view class="item-checkbox-wrap">屏幕有碎裂、缺角、脱胶、气泡</view> -->
	</view>
</view>

此时，collapse(item) 打印出来的是undefined。

解决方法：

将collapse(item)改为 ()=>collapse(item)

<view :class="['inspect-item-wrap', !item.show ? 'collapse': '']" v-for="item in list_arr.attribute_values" :key="item.id">
	<view class="item-show-wrap" @click="()=>collapse(item)">
		<text class="item-title">{{item.name}}</text>
		<!-- <text class="item-tips ml-8">(多选)</text> -->
		<view class="arrow-bottom">
			<image src="../../static/detail/arrow-bottom.png" mode="widthFix"></image>
		</view>
	</view>
	<view class="item-hide-wrap">
		<view :class="['item-checkbox-wrap',isCheck(sonItem) ? 'active':''] " v-for="sonItem in item.option" :key="sonItem.sku"
			@click="checkbox(sonItem)">
			{{sonItem.value}}
		</view>
		<!-- <view class="item-checkbox-wrap">屏幕明显划痕</view>
		<view class="item-checkbox-wrap">屏幕有碎裂、缺角、脱胶、气泡</view> -->
	</view>
</view>

这个时候你就可以拿到对应的属性值了。
