微信小程序的搜索功能可以通过调用微信提供的API来实现。以下是实现搜索功能的方法:
1. 首先,需要在小程序的`app.json`文件中配置搜索相关参数,例如设置搜索框的位置、样式等。
```json
{
"pages": [
"pages/index/index",
"pages/search/search"
],
"window": {
"navigationBarTitleText": "搜索"
},
"tabBar": {
"list": [
{
"pagePath": "pages/search/search",
"text": "搜索",
"iconPath": "static/tabbar/search.png",
"selectedIconPath": "static/tabbar/search-active.png"
}
]
}
}
```
2. 在`pages/search/search`页面中,需要创建一个搜索框组件,并使用微信提供的API进行搜索。
```html
- pages/search/search.wxml -->
```
```css
.container {
display: flex;
justify-content: center;
align-items: center;
height: 100%;
}
.search-box {
width: 100%;
height: 40px;
border: 1px solid #ccc;
margin-bottom: 10px;
}
.search-input {
width: 100%;
height: 100%;
font-size: 16px;
line-height: 40px;
color: #333;
text-indent: 5px;
border: none;
outline: none;
}
.search-btn {
width: 100%;
height: 40px;
background-color: #f56954;
color: #fff;
line-height: 40px;
text-align: center;
border-radius: 5px;
font-size: 16px;
}
```
```javascript
// pages/search/search.js
Page({
data: {
keyword: "",
searchList: [],
loading: false,
pageSize: 10,
currentPage: 1,
total: 0,
totalPage: 0,
searchResult: [],
isSearching: false,
errorMsg: "",
},
onLoad: function () {
this.setData({
keyword: "",
searchList: [],
loading: false,
currentPage: 1,
total: 0,
totalPage: 0,
searchResult: [],
isSearching: false,
errorMsg: "",
});
},
onReady: function () {
this.search();
},
onShow: function () {
if (this.data.isSearching) {
return;
} else {
this.setData({
isSearching: true,
});
}
},
onHide: function () {
this.setData({
isSearching: false,
});
},
search: function () {
if (this.data.keyword === "") {
this.setData({
errorMsg: "请输入关键词",
isSearching: false,
});
return;
} else {
this.setData({
isSearching: true,
});
}
setTimeout(() => {
this.setData({
isSearching: false,
});
this.searchApi();
}, 100);
},
searchApi: function () {
if (this.data.loading) {
return;
} else {
this.setData({
loading: true,
});
wx.request({
url: `https://api.weixin.qq.com/cgi-bin/search/query?keyword=${encodeURIComponent(this.data.keyword)}&page=${this.data.currentPage}`,
method: "GET",
success: (res) => {
if (res.data.total > 0) {
this.setData({
searchResult: res.data.result,
total: res.data.total,
totalPage: res.data.totalPage,
});
} else {
this.setData({
searchResult: [],
total: 0,
totalPage: 0,
});
}
this.setData({
loading: false,
});
},
fail: (err) => {
this.setData({
errorMsg: err.errmsg,
loading: false,
});
},
});
}
},
});
```
3. 在`app.json`文件中配置微信开发者工具的调试信息,以便在开发过程中查看小程序的运行状态。
```json
{
"devtoolsLocation": "/devtools"
}
```
4. 在`pages/search/search`页面中,使用微信开发者工具打开小程序,并进入调试模式。在调试模式下,可以查看到小程序的运行状态和日志信息。
