搞了好久原来是位置的原因唉闹心 
直接上代码： 
出不来的代码：

1. [html] view plain copy print?在CODE上查看代码片派生到我的代码片
2. {
3. "pages": [
4. "pages/splash/splash",
5. "pages/zhuye/zhuye",
6. "pages/list/list",
7. "pages/item/item",
8. "pages/search/search",
9. "pages/profile/profile"
10. ],
11. "window": {
12. "navigationBarBackgroundColor": "#35495e",
13. "navigationBarTextStyle": "white",
14. "navigationBarTitleText": "电影 « 豆瓣",
15. "backgroundColor": "#fff",
16. "backgroundTextStyle": "dark",
17. "enablePullDownRefresh": true
18. },
19. "tabBar": {
20. "color": "#ccc",
21. "selectedColor": "#35495e",
22. "borderStyle": "white",
23. "backgroundColor": "#f9f9f9",
24. "list": [
25. {

27. "pagePath": "pages/zhuye/zhuye",
28. "iconPath": "images/board.png",
29. "selectedIconPath": "images/board-actived.png",

43. "selectedIconPath": "images/profile-actived.png",
44. "text": "我的"
45. }
46. ]
47. },
48. "networkTimeout": {
49. "request": 10000,
50. "connectSocket": 10000,
51. "uploadFile": 10000,
52. "downloadFile": 10000
53. },
54. "debug": true
55. }

解决方案一：把 tabBar配置中的 "pagePath": "pages/zhuye/zhuye",换成 配置为首页的pages/splash/splash就可以了；

方案二：完美解决方案  在wxml里 加入 open-type="switchTab"

1. [html] view plain copy print?在CODE上查看代码片派生到我的代码片
2. <navigator url="../zhuye/zhuye" open-type="switchTab" >
3. <button class="btn" bindtap="start" wx:if="{{index == movies.length - 1}}" >立即体验</button>
4. </navigator>

方案三：  js里面用这个跳转带bar的页面
