Implementation Steps

Overview

• Add ‘oadoi’ to your app variable in custom.js
• Add base code to anonymous function in custom.js
• Add and customize code snippet for local email and icon
• Load icon to img directory
• Note: this customization does not require the central package to be enabled

Steps

1. In your local custom.js file, add ‘oadoi’ to your app variable near the top:
   
   var app = angular.module('viewCustom', ['oadoi']);
   
   If you are using other angular modules, include them in your app definition as well. For example:
   
   var app = angular.module('viewCustom', ['oadoi', 'customAction']);
   
2. Below the “app” declaration (but before the  })(); at the end of the file), add the following code:
   
/******** begin oadoi **********/
angular
.module('oadoi', [])
.component('prmFullViewServiceContainerAfter', {
bindings: { parentCtrl: '<' },
controller: function controller($scope, $http, $element, oadoiService, oadoiOptions) {
this.$onInit = function() {
$scope.oaDisplay=false; /* default hides template */
$scope.imagePath=oadoiOptions.imagePath;
var email=oadoiOptions.email;
var section=$scope.$parent.$ctrl.service.scrollId;
var obj=$scope.$ctrl.parentCtrl.item.pnx.addata;
var debug=oadoiOptions.debug;
if (obj.hasOwnProperty("doi")){
var doi=obj.doi[0];
if(debug){ console.log("doi:"+doi); }
if (doi && section=="getit_link1_0"){
var url="https://api.oadoi.org/v2/"+doi+"?email="+email;
            var response=oadoiService.getOaiData(url).then(function(response){
          if(debug){
console.log("response from oadoiService received:");
              console.log(response);
}
           var oalink=response.data.best_oa_location.url;
            if(oalink===null){
           $scope.oaDisplay=false;
             if(debug){ console.log("oaDisplay set to false (no link returned)"); }
            $scope.oaClass="ng-hide";
            }
            else{
             if(debug){
console.log("oalink from response: " + oalink); }
                $scope.oalink=oalink;
                $scope.oaDisplay=true;
                $element.children().removeClass("ng-hide"); /* initially set by $scope.oaDisplay=false */
                $scope.oaClass="ng-show";
              }
            });
          }
          else{
$scope.oaDisplay=false;
}
        }
        else{
         $scope.oaClass="ng-hide";
        }
      };
    },
    template: '<div style="height:50px;background-color:white;padding:15px;" ng-show="{{oaDisplay}}" class="{{oaClass}}"><img src="{{imagePath}}" style="float:left;height:22px;width:22px;margin-right:10px"><p>Full text available via: <a href="{{oalink}}" target="_blank" style="font-weight:600;font-size:15px;color;#2c85d4;">Open Access</a></p></div>'
  })
.factory('oadoiService', ['$http',function($http){
   return{
     getOaiData: function (url) {
       return $http({
         method: 'GET',
          url: url,
          cache: true
        })
      }
    }
  }]);
/****** end oadoi *********/
   
3. Be sure to edit the constant variables for the image path and email in this section of code.
   
   /******* begin oadoi local options ***********/ 
   app.constant('oadoiOptions', {
      "imagePath": "custom/INSTITUTIONID/img/oa_50.png",
      "email": "me@myschool.edu"
    });
/******** end oadoi local options ***************/
   
4. Modify the imagePath and email fields as follows:
   1. imagePath: this points to an image in your customization package. Make sure you edit the view name so it corresponds to your view, and the file name.
   2. email: enter an email address specific to your institution. There is no need to register it with Unpaywall.
5. Add your icon image to the ‘img’ directory of your customization package. Make sure it matches the file name you entered in step 3 for imagePath. Sample image: oa50_t.png
   
   
   
6. Zip your customization package, load it to Alma Discovery, and save your view.
