angularjs - how to debug an angular for loop -


i trying batch upload of multiple pdfs. each file named in specific format

02-2015 hip bs32

date / pipeline abbreviation / location abbreviation.

i running files through loop compare abbreviations list in database. assign properties object before passed api controller. pipeline , location tables setup same. issue having pipeline. problem is,

$scope.pip = $scope.pipelookup[matches[1]]; $scope.loc = $scope.locationlookup[matches[2]];

the locationlookup matching location abbreviation , placing in $scope.loc variable. pipelookup not working. of course throwing error because pipeline properties undefined. not sure if on looking something. if more information needed let me know pic1 pic2

 $scope.companies = company.query(function () { }); $scope.locations = location.query(function () { }); $scope.pipes = pipe.query(function () { }); $scope.selectcompany = function () {     var id = $scope.companyid.companyid     $http.get('/api/apicompany/' + id)         .success(function (result) {             $scope.companyname = result.companyname         }); };//  $scope.pipelookup = {}; $scope.locationlookup = {};  $scope.upload = function () {     var files = $scope.files;     if (files && files.length) {         (var = 0; < files.length; i++) {             var file = files[i];              $scope.pipes.map(function (pip) {                 $scope.pipelookup[pip['pipeab']] = pip;             });             $scope.locations.map(function (loc) {                 $scope.locationlookup[loc['locationab']] = loc;             });              var matches = file.name.match(/^\d+\d\d+\s*?(\s*)\s*(\s*?)\./i);              $scope.pip = $scope.pipelookup[matches[1]];             $scope.loc = $scope.locationlookup[matches[2]];              $upload.upload({                 url: '/api/apibatchpipeline',                 fields: {                     'typeid': 1,                     'companyid': $scope.companyid.companyid,                     'documentdate': $scope.model.documentdate,                     'pipeid': $scope.pip['pipeid'],                     'pipename': $scope.pip['pipename'],                     'locationid': $scope.loc['locationid'],                     'locationab': $scope.loc['locationab']                 },                 file: file             }).progress(function (evt) {                 var progresspercentage = parseint(100.0 * evt.loaded / evt.total);                 console.log('progress: ' + progresspercentage + '% ' + evt.config.file.name);             }).success(function (data, status, headers, config) {                 console.log('file ' + config.file.name + 'uploaded. response: ' +                             json.stringify(data));             }).error(function (err, result) {                 console.log(err, result);             });          }     }

your regex expecting dot (.) character @ end string doesn't contain dot (.) @ end hence failing.

if try regex ^\d+\d\d+\s*?(\s*)\s*(\s*?)\. here , pass in 02-2015 hip bs32 doesn't match because regex expecting . literal @ end.

update: here fragment of pipelookup json

"hip ": { "$id": "9", "pipeid": 9, "pipeab": "hip ", "pipename": "american midstream high point pipeline", "documents": null

}

here key "hip " notice space after hip. why $scope.pipelookup[matches[1]] returns nothing. remove trailing space before storing in pipelookup object

update: on more closer look, if file.name contains value 02-2015 hip bs32 , if want hip value out of can use following regex

/^\d+\d\d+\s*(\s*\s*)(\s*)/i

here jsbin live demo of regex example

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
