the first thing you need to understand is that under two-way data binding, you do not modify the data that needs to be used in the loop in this array, so the list will not change when rendered. When you click, you can use a value to define which one is currently clicked, and then modify the style of the element
<view wx:for="{{TabList}}" wx:for-item="tab" data-tabid='{{tab.TabId}}' wx:for-index="tabindex" data-index="{{tabindex}}" class="{{tabindex == selectTab ? 'index-tab-select' : ''}}" bindtap='switchTab'>{{tab.MarketTitle}}</view>switchTab: function (e) {
var index = e.currentTarget.dataset.index
var tabid = e.currentTarget.dataset.tabid
this.setData({
selectTab: index
})
} Save className as an array of follow data for rendering. Click element under a index , then modify the className corresponding to index , and render again.
