微信小程序Picker为什么我调用后要下拉两次才能改变数值？求各位大佬帮帮忙看看是不是我调用有问题。 JS: Page{ data：{ id:0 }, button1:funcation(e) { var that = this; that.setData({ id: e.detail.value }); wx.setStorageSync("name", e.currentTarget.dataset.selecthx) wx.setStorageSync("name1", e.currentTarget.dataset.selecthx1) } } wxml: <picker class="cybm_pic_1" value="{{id}}" range="{{list1}}" range-key="name" data-selecthx="{{list1[id].id}}" data-selecthx1="{{list1[id].name}}" bindchange="button1" >
