为什么wx:for-items列表渲染[object Object]？
addAttributeType: function (e) {
let idx = e.currentTarget.dataset.index;
let arr = (this.data.attribute[`${idx}`].type) ? this.data.attribute[`${idx}`].type : [];
let obj = new Object;
obj["name"] = this.data.attributeType;
obj["checked"] = false;
arr.push(obj);
this.setData({
[`attribute[${idx}].type`]: arr,
attributeType: '',
})
console.log("属性列表：：：", this.data.attribute)
},
<block wx:for-items="{{item.type}}" wx:key="items">
<view class="tag_item" data-idx="{{idx}}" data-cur="{{index}}" catchtap="delAttributeType">
<text>{{items.name}}</text>
</view>
</block>
已解决。我在父级view加了wx:for-index ，下一级wx:for-items循环的*this被改变了。把父级view的wx:for-index，放到子元素就好了。不知道这样表述对不对，如果不对，请指正。
更新后的代码
<block wx:for="{{attribute}}" wx:key="item"> <view> <view class="flex-space title"> <text>{{item.name}}</text> <button class="btn_like btn_off" data-index="{{index}}" catchtap="delAttribute"> <text class="iconfont iconfont-off"></text> </button> </view> <view class="content"> <view class="flex-space input_add"> <input value="{{attributeType}}" type="text" placeholder="属性值" placeholder-style="color: #9089BC;" cursor-spacing="49" confirm-type="next" bindinput="inputAttributeType" /> <button class="btn_like btn_add" data-index="{{index}}" catchtap="addAttributeType"> <text class="iconfont iconfont-jia"></text> </button> </view> <view class="flex-center tag_box"> <block wx:for-items="{{item.type}}" wx:for-index="idx" wx:key="item"> <view class="tag_item" data-cur="{{idx}}" data-idx="{{index}}" catchtap="delAttributeType"> <text>{{item.name}}</text> </view> </block> </view> </view> </view> </block>wx:key="items" items?
