passing html values to javascript functions - html

Question

I have a ng-repeat in my view and I want to pass the object from my ng-repeat to a javascript function but when I try to display it on the console it gives me undefined.
Here is my html:
<!-- Panel -->
<div class="row">
<div class="col-lg-12">
<div class="panel panel-primary">
<div class="panel-heading">
{{card}}
</div>
<!-- /.panel-heading -->
<div class="panel-body">
<div id="nvd3-container" class="md-card" style="overflow-x: auto" ng-if="dataloaded0">
<md-card-content id="nvd3-scrollable-content" style="width: {{width}}px; height: 350px;">
<md-tabs md-dynamic-height="" md-border-bottom="">
<md-tab ng-repeat="pu in selectedKpi" label="{{pu.dprdProuNr}}">
<md-content class="md-padding">
<div class="row">
<div class="col-md-6">
{{pu.item1}}
{{pu.item2}}
</div>
</div>
</md-content>
</md-tab>
</md-tabs>
</md-card-content>
</div>
</div>
<!-- /.panel-body -->
<a href="" ng-click="footerLinkClicked(pu)">
<div class="panel-footer">
<span class="pull-left">Trend</span>
<span
class="pull-right">
<i class="fa fa-arrow-circle-right"></i>
</span>
<div class="clearfix"></div>
</div>
</a>
</div>
</div>
</div>
<!-- /.panel -->
Here is my js file that returns undefined:
angular.module('App')
.directive('KpiParameter', function() {
return {
restrict: 'E',
templateUrl: 'app/kpi/kpi-parameter/kpi-parameter.html',
scope: {
card: '=',
kpiParamCallback: '&',
selectedProductionUnit: '<'
},
controller: function($scope, $rootScope, KpiChartFactory, $filter) {
console.log("!???????");
console.log($scope.selectedProductionUnit);
$scope.$watch('selectedProductionUnit', function() {
console.log($scope.selectedProductionUnit);
console.log("Changed");
KpiParamUpdated();
$scope.kpiParamCallback({
selectedProductionUnit: $scope.productionUnitDefault
});
}, true);
function KpiParamUpdated() {
console.log("KPiParamUpdated");
console.log($scope.selectedProductionUnit);
$scope.dataloaded0 = true;
KpiChartFactory.get({ pu: $scope.selectedProductionUnit }, function(data) {
$scope.selectedKpi = data;
console.log($scope.selectedKpi);
$rootScope.$broadcast('kpiParams', $scope.selectedKpi);
});
}
$scope.footerLinkClicked = function(pu) {
console.log("parameters received :");
console.log(pu);
}
},
controllerAs: "KpiPCtrl"
};
});
Do you have any idea why? I need to define it also in my js file?

Answer 1

As found in the docs of AngularMaterial, you can only achieve what you want to do by using md-on-select
Attributes
Parameter Type Description
label string
Optional attribute to specify a simple string as the tab label
ng-disabled boolean If present and expression evaluates to truthy, disabled tab selection.
md-on-deselect expression Expression to be evaluated after the tab has been de-selected.
md-on-select expression Expression to be evaluated after the tab has been selected.
md-active boolean When true, sets the active tab. Note: There can only be one active tab at a time.
Note: This event differs slightly from ng-click, in that if a tab is already selected and then clicked, the event will not fire.

Your call to footerLinkClicked() has no way of knowing which pu to use unless you tell it which one to use. And since it's outside of your ng-repeat, there's no overly easy way to do that.
md-tabs has an attribute called md-selected that allows you to store the currently selected index in a variable. So assuming that selectedKpi is an array (or is array-like), you can do this:
<md-tabs md-dynamic-height="" md-border-bottom="" md-selected="selectedTab">
and this:
<a href="" ng-click="footerLinkClicked(selectedKpi[selectedTab])">
and you should be all set.
