One of my tasks involves displaying a list of elements through the ng-repeat directive. Each element is contained within its own div block. My goal now is to enable editing for each block, so that when users click on an edit button, the content of the div transforms into a form that can be submitted...
I am determined to adhere to AngularJS's philosophy and avoid manipulating the DOM directly in the controller. Instead, I plan to leverage directives to handle this... ;-)
If you're looking for a way to toggle between displaying elements as read-only or in edit mode, one approach is to use conditional rendering. Here's an example implementation:
<div ng-repeat="item in list">
<div ng-hide="isEditMode(item.id)">
<!-- Read-only display of item -->
<span>{{ item.text }}</span>
<button type="button" ng-click="enableEditMode(item.id)">
Edit
</button>
</div>
<div ng-show="isEditMode(item.id)">
<!-- Editable form for the item -->
<input type="text" ng-model="item.text">
<button type="button" ng-click="saveChanges(item)">
Save
</button>
</div>
</div>
In your controller, define the following functions and variables:
$scope.list = [
{ id: 1, text: "item_1" },
{ id: 2, text: "item_2" }
];
$scope.itemIdInEditMode = 0;
$scope.isEditMode = function(itemId) {
return $scope.itemIdInEditMode === itemId;
};
$scope.enableEditMode = function(itemId) {
$scope.itemIdInEditMode = itemId;
};
$scope.saveChanges = function(item) {
// Implement logic to update the item in $scope.list or backend
};
This setup allows for easy switching between read-only and edit modes for items in the list using AngularJS. The two-way data binding feature automatically updates the model when input values change, simplifying the process of editing items.
