Hi Experts,

I am developing single page application using angularjs,html5,bootstrap and ASP.net MVC.The landing page has 3 tabs and common Save for all the tabs and in one of the tab I have a dropdown and the code is  similar to below code in Angular.First time when the page loads the value for the dropdown should be "None" and if user selects a value  in the dropdown  and navigates to other tabs and return backs to dropdown and should see last selected option ie. I should maintain the previous state of the dropdown while navigating the tabs.

In the below example if I select  option "Yellow" and then navigate to other tabs and back to original tab it should retain "Yellow" option. That means I should only show "None" at the first time when user Login.

In the code , I am just initializing the dropdown value  to "None" in the controller at all times , but I need this to be "None" only first time.How can I achieve this using angularjs?


 $scope.state = $scope.status[0]; //This will always set tDropdown to None

Hi,

I think you need to check $scope.state before setting it:
    if (typeof $scope.state === 'undefined') {
            $scope.state = $scope.status[0];
    }

Open in new window
