Use JSSDK to obtain geographical location from web pages
Copy a copy of the JSSDK environment and create an index.html file. The structure is as shown in Figure 7.1.
Figure 7.1 Section 7.1 File Structure
In location.js, encapsulate the "getLocation" interface as follows:
01 wxJSSDK.location = function(locationApi){
02 if(wxJSSDK.isReady){ //wxJSSDK.isReady 查看微信JSSDK是否初始化完毕
03 if(locationApi){
04 locationApi.getLocation && wx.getLocation({ //获取地理位置接口
05 success: function (res) {
06 locationApi.getLocation.success &&
07 locationApi.getLocation.success(res);
08 }
09 });
10 }else{
11 console.log("缺少配置参数");
12 }
13 }else{
14 console.log("抱歉，wx没有初始化完毕，请等待wx初始化完毕，再调用位置接口服
15 务。");
16 }
17 }In the index.html file, add the "Get geographical location" button and display the location information after acquisition. The code structure is as follows:
01 <!DOCTYPE html>
02 <html lang="en">
03 <head>
04 <metacharset="UTF-8">
05 <meta name="viewport" content="width=device-width,initial-scale=1.0,

39 </head>
40 <body>
41 <h1 style="font-size: 8em">:)</h1>
42 <b style="font-size: 3em">位置操作接口！</b><br/><br />
43 <div id="info">
44 <p>纬度：<em id="latitude">无</em></p>
45 <p>经度：<em id="longitude">无</em></p>
46 <p>速度：<em id="speed">无</em></p>
47 <p>位置精度：<em id="accuracy">无</em></p>
48 </div>
49 <input type="button" value="获取当前地理位置信息" id="getLocation" />
50 </body>
51 </html>
Then add the response event in location.js, the code is as follows:
01 window.onload = function(){
02 var latitude,longitude, speed ,accuracy; // 位置信息初始变量
03 $("#getLocation").click(function(){ // 获取地理位置接口
04 wxJSSDK.location({
05 getLocation:{
06 success:function (res) {
07 latitude = res.latitude; // 纬度，浮点数，范围为90 ~ -90
08 $("#latitude").html(latitude);
09 longitude = res.longitude; // 经度，浮点数，范围为180 ~ -180。
10 $("#longitude").html(longitude);
11 speed = res.speed; // 速度，以米/每秒计
12 $("#speed").html(speed);
13 accuracy = res.accuracy; // 位置精度
14 $("#accuracy").html(accuracy);
15 }
16 }
17 });
18 });
19 }
Finally, remember to add the "getLocation" API permissions to the JSSDK configuration environment.
[Code Explanation]
After the location of "getLocation" is successful, the relevant information of "Latitude", "Longitude", "Speed" and "Position Accuracy" will be returned. After clicking the "Get Location" button, WeChat will pop up a prompt message, as shown in Figure 7.2. The result after successfully obtaining the location service is shown in Figure 7.3.

What should I do if the images on the webpage cannot be loaded? 6 solutions
Mar 15, 2024 am 10:30 AM
Some netizens found that when they opened the browser web page, the pictures on the web page could not be loaded for a long time. What happened? I checked that the network is normal, so where is the problem? The editor below will introduce to you six solutions to the problem that web page images cannot be loaded. Web page images cannot be loaded: 1. Internet speed problem The web page cannot display images. It may be because the computer's Internet speed is relatively slow and there are more softwares opened on the computer. And the images we access are relatively large, which may be due to loading timeout. As a result, the picture cannot be displayed. You can turn off the software that consumes more network speed. You can go to the task manager to check. 2. Too many visitors. If the webpage cannot display pictures, it may be because the webpages we visited were visited at the same time.

Which AI programmer is the best? Explore the potential of Devin, Tongyi Lingma and SWE-agent
Apr 07, 2024 am 09:10 AM
On March 3, 2022, less than a month after the birth of the world's first AI programmer Devin, the NLP team of Princeton University developed an open source AI programmer SWE-agent. It leverages the GPT-4 model to automatically resolve issues in GitHub repositories. SWE-agent's performance on the SWE-bench test set is similar to Devin, taking an average of 93 seconds and solving 12.29% of the problems. By interacting with a dedicated terminal, SWE-agent can open and search file contents, use automatic syntax checking, edit specific lines, and write and execute tests. (Note: The above content is a slight adjustment of the original content, but the key information in the original text is retained and does not exceed the specified word limit.) SWE-A
