WXML
<block wx:for="{{images}}" wx:key="*this" wx:for-index="idx">
<view wx:if="{{"item"+idx > 0}}" class="q-image-progress">
</view>
<image src="{{item}}" mode="aspectFill" data-idx="{{idx}}" bindtap="handleImagePreview"></image>
</block>js
onLoad: function(options) {
let images=["0.jpg"];
for(let i=0;i<images.length;iPP){
const key = `item${i}`
console.log(key)
this.setData({
[key]:0
})
}
} I want to get the dynamically generated value of "item"+idx in wxml, and now" item"+idx"in wx:if= "{{"item"+idx > 0}" generates the string item0 directly instead of getting the value of item0 in JS.
could you tell me how to get the dynamically generated values in JS in wxml?
