button和tabBar都具有跳转到某个页面的功能时，button失效

app.json定义了tabBar的测试按钮跳转到test

{   "pages":[     "pages/index/index",     "pages/test/test"   ],   "window":{     "backgroundTextStyle":"light",     "navigationBarBackgroundColor": "#fff",     "navigationBarTitleText": "WeChat",     "navigationBarTextStyle":"black"   },   "tabBar": {     "list": [       {         "pagePath": "pages/index/index",         "text": "首页"       },       {         "pagePath": "pages/test/test",         "text": "测试"       }     ]   } }

index.js中定义了test按钮跳转到test页面

test:function(){     wx.navigateTo({       url: '../test/test'     })   }

会导致test按钮无法执行跳转代码
