Mobile Scan ID for obtaining identity card information.

Mobile scan ID for ID card information (front-end section)
Recently made a scan of the identity of the function of the following several steps

1: Use h5+ to call the phone camera

if (window.plus) {Playcamera ();} else{Document.addeventlistener ("Plusready", Playcamera (), false);

Call camera to take pictures:

Playcamera:function () {var _self=ext.getcmp ("Add_client_view");   var CMR = Plus.camera.getCamera ();   var res = Cmr.supportedimageresolutions[0];var FMT = cmr.supportedimageformats[0];cmr.captureimage (path) {_ Self. Getbase64code (path);},function (Error) {alert ("Capture image failed:" + error.message);}   ,

2: Convert acquired images to base64 format data

There are 2 ways to convert base64 format photos here:
(1): Use H5 FileReader according to the picture Road to convert to Base64 format picture;

Convert the picture to Base64 format   img2dataurl:function (path) {   Plus.io.resolveLocalFileSystemURL (path, function (entry) {        entry.file (function (file) {        debugger            var reader = new Plus.io.FileReader ();            Reader.onload = function (e) {            imgbase64=e.target.result;                Console.log ("* * * *" +e.target.result);            };            Reader.readasdataurl (file)        ,},function (e) {           ext.toast ("Read and write exception:" + E.message)        ,})   },

　　

(2): Use bitmap native Picture object provided by h5+
Please see here Http://www.html5plus.org/doc/zh_cn/nativeobj.html#plus.nativeObj.Bitmap the concrete method;
With detailed instructions

Getbase64code:function (path) {   var bitmap = new Plus.nativeObj.Bitmap ("xxx");   Load bitmap picture from local to convert picture to base64 format        bitmap.load (Path,function () {            var base4=bitmap.tobase64data ();            var datastr=base4.split (', ', 3);//intercept the useless prefix            var imgbase64 = [];            if (datastr.length>1)            {               imgbase64.push (datastr[1]);            } else            {               imgbase64.push (datastr[0]);            }            Console.log (imgbase64);            var traceno=utils.gentrn ();//serial number//Then send Ajax request        },function (e) {            console.log (' Load picture failed: ' +json.stringify (e) );        });   },

　　

(3) Call Ali identity card Scan information interface, obtain identity card information;
