Is it possible to display specific fields on a page depending on the value stored in $localStorage?
For example, consider the following code snippet:
<div ng-controller="myCtrl">
<ul>
<li> List 1 </li>
<li> List 2 </li>
<li> List 3 </li>
<li> List 4 </li>
</ul>
</div>
If I only want to show List 3 and List 4 when the value of $localStorage is not equal to 0, how can I achieve this?
To retrieve a value from the $localStorage and assign it to a scope variable, you can use the following code snippet and then check the variable using ng-if directive.
$scope.condvalue = localStorage.getItem("yourItem");
HTML:
<div ng-controller="myCtrl">
<ul>
<li> List 1 </li>
<li> List 2 </li>
<li ng-if="condvalue!=0"> List 3 </li>
<li ng-if="condvalue!=0"> List 4 </li>
</ul>
</div>
First, make sure to include $window in your controller in order to utilize localStorage.
// Define the variable ListisnotZero here
$window.localStorage.setItem("ListisnotZero", ListisnotZero);
// Retrieve it from the local storage
$scope.ListisnotZero = $window.localStorage.getItem("ListisnotZero");
// In the HTML template
<div ng-controller="myCtrl">
<ul>
<li>List 1</li>
<li>List 2</li>
<li ng-if="ListisnotZero != 0">List 3</li>
<li ng-if="ListisnotZero != 0">List 4</li>
</ul>
</div>
