微信小程序之豆瓣电影

此文是学习小程序第二天做出的一个小demo,调用了豆瓣电影的api,但是需要填上自己appId,现在项目的目录如下图：

效果图如下：

在这个demo里面，我更改了小程序的navigationBar，设置了最下方的三个tabBar,这是公共的设置需要在app.json里面设置，

 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": "豆瓣电影",
13 "navigationBarTextStyle": "#fff"
14 },
15 "tabBar": {
16 "backgroundColor": "#222",
17 "list": [
18 {
19 "pagePath": "pages/index/index",
20 "text": "当前热映",
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": "查询",
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，把几个公共页面的样式抽离出来，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 font-size: 16px;
29 }
30 
31 .move-item_moveName{
32 font-size: 16px;
33 }
34 .move-item_fontSize {
35 font-size: 13px;
36 }

当前热映部分的代码
