ServiceNow - Embedded widget on catalog item - how to pass a variable from the cat item form

 

Client controller:

api.controller = function($scope) {
    /* widget controller */
    var c = this;


    $scope.$watch(function() {
        if ($scope.page.g_form) {
            return $scope.page.g_form.getValue('service_offering');
        }

    }, function(value, oldValue) {

        //validate that value is not the same as oldValue (loading)
        if (value != oldValue) {
            //execute on change of the variable
            c.data.message = value;
            c.server.update();
            //  alert(value);
        }

    });




    c.display = function(a) {
        //alert(a);
        $scope.page.g_form.setDisplay('parent_incident', true);
        $scope.page.g_form.setValue('parent_incident', a.toString());
        $scope.page.g_form.setDisplay('parent_incident', false);
        //g_form.setDisplay('parent_incident',false);
    };

};

 

Server script:

 (function() {
    /* populate the 'data' object */
    /* e.g., data.table = $sp.getValue('table'); */
    if (input) {
        //gs.addErrorMessage('gr.number.toString()');
        var items = [];
        var idx = 0;
        //  var item = {};
        session.onlineImpersonate("system");
        var itemsGR = new GlideRecord("incident");
        itemsGR.addQuery("service_offering", input.message);
        itemsGR.addEncodedQuery('active=true^major_incident_state=accepted');
        itemsGR.queryNoDomain(); //--to avoid any cross-domain issues
        while (itemsGR.next()) {
            var item = {};
            item.short_description = itemsGR.short_description.toString();
            item.num = itemsGR.number.toString();
            //item.business_impact = itemsGR.business_impact;
            item.sysId = itemsGR.sys_id.toString();
            // item.shorty =gr12.short_description.toString();
            items[idx] = item;
            //gs.addErrorMessage('gr.number.toString()'+ items[idx].toString());
            idx++;
        }

        data.items = items;
        session.onlineUnimpersonate();
    }

})();

 

HTML:

<div ng-show="data.items">
  <div ng-hide="data.items==''">
  <h5 class = "mi" id='infomsg1'> Are you impacted by any of below Incident?</h5>
  </div>
</div>
  <div ng-repeat="item in data.items"  ng-controller="RadioController">
 
         <input type="radio" name="incidents"   id="{{item.sysId}}"     ng-click="c.display(item.sysId)"/> {{::item.num}} - {{::item.short_description}}

</div>
   

CSS:

.mi {color: red;
  font-size: 15px;
  font-weight: bold;
