Currently, my server is using handlebars to generate the initial HTML page. I would like to include a ng-include in this page to dynamically update the client side.
However, every time my application runs, it loads the page and the data-ng-include="template.url" directive loads template.url as expected. Is there a way for ng-include to load this data only after my application has finished loading?
Take a look at this plunker for reference. Review the code inside index.html!
If you're looking to simplify your code, consider using the ng-if directive in AngularJS. By checking for its initial loading status, you can streamline your development process.
<ANY ng-if="expression">
// Add your code here
</ANY>
For example:
<ANY ng-if="false">
// This code will not be executed
</ANY>
This method can make a difference in your coding experience. Here's an example of how it can be implemented:
<body>
<div data-ng-controller="ctrl">
<div data-ng-include="template.url" ng-if="false">
Content that should only appear after a button is clicked.
</div>
<button type="button" data-ng-click="second()">Click me!</button>
</div>
To effectively implement this in your code, adjust the conditions in your .js file. See the modified code below:
angular.module('myApp', [])
.controller('ctrl', ['$scope', function ($scope) {
$scope.templates =
[ { name: 'first.html', url: 'first.html'},
{ name: 'second.html', url: 'second.html'} ];
if (false){
$scope.template = $scope.templates[0];
}
$scope.second = function () {
$scope.template = $scope.templates[1];
};
$scope.first = function () {
$scope.template = $scope.templates[0];
};
}]);
Instead of using $location, you may consider the following solution for editing your code:
Delete the code within the index.html file to make it look like this:
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<script data-require="<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="5b3a353c2e373a297531281b6a756f756d">[email protected]</a>" data-semver="1.4.6" src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.6/angular.min.js"></script>
<script src="script.js"></script>
</head>
<body>
<div data-ng-controller="ctrl">
<div data-ng-include="template.url"></div>
</div>
</body>
</html>
2.Update your script.js as follows:
angular.module('myApp', [])
.controller('ctrl', ['$scope', function ($scope) {
$scope.templates =
[ { name: 'init.html', url: 'init.html'},
{ name: 'first.html', url: 'first.html'},
{ name: 'second.html', url: 'second.html'} ];
$scope.template = $scope.templates[0];
$scope.second = function () {
$scope.template = $scope.templates[2];
};
$scope.first = function () {
$scope.template = $scope.templates[1];
};
}]);
3.Create a new file init.html with the following content:
Here is some stuff that should stay until I click the button below.
<button type="button" data-ng-click="second()">Click me!</button>
