搞了好久原來是位置的原因唉鬧心 
直接上代碼： 
出不來的代碼：

1. [html] view plain copy print?在CODE上查看代碼片派生到我的代碼片
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": "電影 « 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. {
26.  
27. "pagePath": "pages/zhuye/zhuye",
28. "iconPath": "images/board.png",
29. "selectedIconPath": "images/board-actived.png",
30. "text": "榜單"
31. },
32. {
33.  
34. "pagePath": "pages/search/search",
35. "iconPath": "images/search.png",
36. "selectedIconPath": "images/search-actived.png",
37. "text": "搜索"
38. },
39. {
40.  
41. "pagePath": "pages/profile/profile",
42. "iconPath": "images/profile.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. }

解決方案一：把 tabBar配置中的 "pagePath": "pages/zhuye/zhuye",換成 配置為首頁的pages/splash/splash就可以了；

方案二：完美解決方案  在wxml里 加入 open-type="switchTab"

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

方案三：  js里面用這個跳轉(zhuǎn)帶bar的頁面
