公众平台网页打开报错 [图片]

之前在Page({}) 里增加了一个onTabItemTap函数，之前测试此函数可以正常调用；最近发现不起作用了；开发工具测试结果：首次进入时点击不起作用，进入页面后点击才调到此函数，而手机测试 怎么也调不到此函数。 onTabItemTap(item) {     wx.showToa }

{errMsg: "setTabBarBadge:fail not TabBar page"} 代码如下 wx.setTabBarBadge({ index: 0, text: '3', success: function (res){ console.log(res) }, fail: function (res) { console.log(res) } }) "tabBar": { "color": "#666", "selectedColor": "#dd524d", "borderStyle": "black", "backgroundColor": "#ffffff", "list": [ { "pagePath": "pages/index/index", "iconPath": "resources/images/icon/first.png", "selectedIconPath": "resources/images/icon/first_se.png", "text": "首页" }, { "pagePath": "pages/cart/cart", "iconPath": "resources/images/icon/cart.png", "selectedIconPath": "resources/images/icon/cart_se.png", "text": "购物车" }, { "pagePath": "pages/mine/mine", "iconPath": "resources/images/icon/mine.png", "selectedIconPath": "resources/images/icon/mine_se.png", "text": "我的" } ] }
