I'm trying to get Angular-UI dropdown to work:
- How do I pass the value to my Angular function so I can process it?
- How can I display the selected choice after the user selects it instead of always showing "Please Select:"

Reset to default 6For Angular 4 with Bootstrap v4.0.0-alpha.6, here's a tip on how you could do this:
HTML for Bootstrap dropdown control
<div class="form-group row">
<label class="col-md-3 form-control-label">Account</label>
<div class="col-md-9">
<div class="btn-group" dropdown>
<button dropdownToggle type="button" class="btn btn-primary dropdown-toggle">
{{selectedValue}} <span class="caret"></span>
</button>
<ul dropdownMenu class="dropdown-menu" role="menu">
<li *ngFor="let account of accounts" value="{{account._id}}" (click)="selectValue(account)"
class="dropdown-item">{{account.firstname}} {{account.lastname}}
</li>
</ul>
</div>
</div>
</div>
JS Component Code
export class UserFormComponent implements OnInit {
selectedValue: string = '-- select value --';
selectedId: string;
// On-Click Method on dropdown control
selectValue(account: Account) {
this.selectedValue = account.firstname + ' ' + account.lastname;
this.selectedId = account._id;
}
}
In your HTML, modify the code related to the dropdown to add binding to the text displayed in the dropdown (via ng-bind) + execute a function when an element in the dropdown is clicked (via ng-click) :
<div class="dropdown">
<button class="btn btn-default dropdown-toggle"
type="button" id="menu1" data-toggle="dropdown" ng-click="toggled" ng-bind='selected'>Tutorials
<span class="caret"></span></button>
<ul class="dropdown-menu" role="menu" aria-labelledby="menu1">
<li role="presentation" ng-repeat="choice in items">
<a role="menuitem" ng-click="setTutorial(choice)" tabindex="-1" href="#">{{choice}}</a>
</li>
</ul>
</div>
Then in the javascript, add this function which is executed when an element in the dropdown is clicked:
$scope.selected = "Tutorial";
$scope.setTutorial = function(value) {
$scope.selected = value;
}
With this function, you can:
1. get the value of the item which is clicked
2. update the selected choice.
