發(fā)布時(shí)間：2018-01-04 11:44 所屬欄目：小程序開發(fā)教程
此文是學(xué)習(xí)小程序第二天做出的一個(gè)小demo,調(diào)用了豆瓣電影的api,但是需要填上自己appId,現(xiàn)在項(xiàng)目的 目錄如下圖：
效果圖如下：
在這個(gè)demo里面，我更改了小程序的navigationBar，設(shè)置了最下方的三個(gè)tabBar,這是公共的設(shè)置需要在app.json里面設(shè)置，
1 {
2
3 "pages": [
4 "pages/index/index",
5 "pages/logs/logs",
6 "pages/query/index",
7 "pages/moveTop/index"
8 ],
9 "window": {
10 "backgroundTextStyle": "light",
11 "navigationBarBackgroundColor": "#222",
12 "navigationBarTitleText": "豆瓣電影",
13 "navigationBarTextStyle": "#fff"
14 },
15 "tabBar": {
16 "backgroundColor": "#222",
17 "list": [
18 {
19 "pagePath": "pages/index/index",
20 "text": "當(dāng)前熱映",
21 "iconPath": "pages/images/collection-o.png",
22 "selectedIconPath": "pages/images/collection.png"
23 },
24 {
25 "pagePath": "pages/moveTop/index",
26 "text": "影片排行榜",
27 "iconPath": "pages/images/examResult-time.png",
28 "selectedIconPath": "pages/images/icon_clock.png"
29 },
30 {
31 "pagePath": "pages/query/index",
32 "text": "查詢",
33 "iconPath": "pages/images/nav_icon.png",
34 "selectedIconPath": "pages/images/icon_nav_cell.png"
35 }
36 ]
37 }
38 }
我在做好小程序之后，把幾個(gè)公共頁面的樣式抽離出來，放到了app.wxss文件里面
1 /**app.wxss**/
2 .container {
3 height: 100%;
4 padding: 0;
5 }
6
7 .list_img {
8 float: left;
9 width: 120px;
10 }
11
12 image {
13 width: 100%;
14 height: 140px;
15 padding: 20px 20px 0 20px;
16 }
17
18 .list_info {
19 float: left;
20 width: 210px;
21 height: 140px;
22 padding-left: 30px;
23 padding-top: 40px;
24 }
25
26 .move-item_fontWeight {
27 font-weight: bold;
28
29 }
30
31 .move-item_moveName{
32
33 }
34 .move-item_fontSize {
35 font-size: 13px;
36 }
