In this issue, the editor will bring you about how HTML5+jQuery uses JSSDK to obtain geographical location in the web page. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

Copy a JSSDK environment and create an index.html file.

In location.js, encapsulate the "getLocation" interface as follows:

01 wxJSSDK.location = function (locationApi) {02 if (wxJSSDK.isReady) {/ / wxJSSDK.isReady check whether Wechat JSSDK is initialized 03 if (locationApi) {04 locationApi.getLocation & & wx.getLocation ({/ / get geolocation API 05 success: function (res) {06 LocationApi.getLocation.success & 07 locationApi.getLocation.success (res) 08} 09}); 10} else {11 console.log ("missing configuration parameters"); 12} 13} else {14 console.log ("Sorry, wx is not initialized, please wait for wx initialization, and then take oral 15 services at the calling location.") ; 16} 17}

In the index.html file, add the "get Geographic location" button, and display the location information after acquisition. The code structure is as follows:

01 02 03 04 05 07 Chapter 7 Section 7.1 location Operation Interface 08 09 10 11 12 13 14 15 16 17 18 19 input {20 width: 100% 21 padding: 0.2 62c462 22 background-color: # 5eb95e political 23 font-size: 1.4 emscape 24 background-image: linear-gradient (to bottom, # 62c462, # 57a957); 25 background-repeat: repeat-x;26 color: # ffffff;27 text-align: center 28 text-shadow: 0-1px 0 rgba (0,0,0,0.25); 29 border-radius: 0.3emscape 30} 31 # info {32 border-left: 3px solid#03a9f4;33 background-color: # 5eb95escape 34 color: # ffffff;35 border-radius: 0.3em 36 text-shadow: 0-1px 0 rgba (0,0,0,0.25); 37} 38 39 40 41:) 42 position operator interface! 43 44

Latitude: no 45

Longitude: none 46

Speed: no 47

Position accuracy: no 48 49 50 51

Then add the response event to the location.js, as follows:

01 _ window.onload = function () {02 var latitude,longitude, speed, accuracy / / location information initial variable 03 $("# getLocation") .click (function () {/ / get geolocation interface 04 wxJSSDK.location ({05 getLocation: {06 success:function (res) {07 latitude = res.latitude) / / Latitude, floating point number, range is 90 ~-9008 $("# latitude") .html (latitude); 09 longitude = res.longitude; / / longitude, floating point number, range is 180 ~-180. 10 $("# longitude") .html (longitude); 11 speed = res.speed; / / speed, 12 $("# speed") .html (speed) in meters per second; 13 accuracy = res.accuracy / / position accuracy 14 $("# accuracy") .html (accuracy); 15} 16} 17}); 18}); 19}

Finally, remember to add the permission of "getLocation" API to the configuration environment of JSSDK.

This is how the HTML5+jQuery shared by the editor uses JSSDK to get the geographical location on the web page.
