小程序表单当中利用多选设置了一个《免责条款》，但是程序默认是选中的，怎么修改能让他不默认选中呢
<view class="flex-grow-1 flex-row" style="flex-wrap:wrap" wx:if="{{form.type=='checkbox'}}">
<view bindtap="selectForm" class="default {{v.is_selected==1?'d-active':''}}" data-form-id="{{formId}}" data-index="{{index}}" data-k="{{k}}" style="border-radius:0" wx:for="{{form.default_list}}" wx:for-index="k" wx:for-item="v" wx:key="{{v.id}}">{{v.name}}</view>
</view>
onLoad() { const { form: { default_list = [] } = {} } = this.data default_list[0].is_selected = false this.setData({ default_list }) }onLoad: function(t) {getApp().page.onLoad(this, t);var e = util.formatData(new Date());getApp().core.removeStorageSync(getApp().const.INPUT_DATA), this.setData({options: t,time: e}), is_loading_show = !1;},onLoad() {const { form: { default_list = [] } = {} } = this.datadefault_list[0].is_selected = falsethis.setData({default_list})}通过下面的样式控制选中与否的么？v.is_selected 设置为0
...class="default {{v.is_selected==1?'d-active':''}}"...
