Dynamically Modifying Headers in AngularJS Partial Views
In AngularJS, managing page headers and titles across different partial views can present a challenge. To address this, various approaches have been explored, including leveraging view controllers and shared services. However, a simpler and more efficient solution has emerged for scenarios involving routing.
Solution Using Routing
The provided code demonstrates how to seamlessly update your page title and h1 header when changing between AngularJS partial views:
<code class="javascript">var myApp = angular.module('myApp', ['ngResource']);
myApp.config(
['$routeProvider', function($routeProvider) {
$routeProvider.when('/', {
title: 'Home',
templateUrl: '/Assets/Views/Home.html',
controller: 'HomeController'
});
$routeProvider.when('/Product/:id', {
title: 'Product',
templateUrl: '/Assets/Views/Product.html',
controller: 'ProductController'
});
}]);
myApp.run(['$rootScope', function($rootScope) {
$rootScope.$on('$routeChangeSuccess', function (event, current, previous) {
$rootScope.title = current.$$route.title;
});
}]);</code>
This solution utilizes the $routeChangeSuccess event, which triggers whenever a successful route change occurs. Within this event listener, you can retrieve the title from the current route configuration and assign it to the $rootScope.title property.
HTML:
In your HTML, you can then bind the page title and h1 header to the $rootScope.title property:
<code class="html"><head>
<title ng-bind="'myApp &mdash; ' + title">myApp</title>
...
<body>
<h1 ng-bind="title"></h1></code>
By leveraging the ng-bind attribute, the page title and h1 header will automatically update when the route changes. This solution provides a clean and efficient way to dynamically manage your header information based on the current partial view.

How to work with dates and times in js?
Jul 01, 2025 am 01:27 AM
The following points should be noted when processing dates and time in JavaScript: 1. There are many ways to create Date objects. It is recommended to use ISO format strings to ensure compatibility; 2. Get and set time information can be obtained and set methods, and note that the month starts from 0; 3. Manually formatting dates requires strings, and third-party libraries can also be used; 4. It is recommended to use libraries that support time zones, such as Luxon. Mastering these key points can effectively avoid common mistakes.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.
How can you reduce the payload size of a JavaScript application?
Jun 26, 2025 am 12:54 AM
If JavaScript applications load slowly and have poor performance, the problem is that the payload is too large. Solutions include: 1. Use code splitting (CodeSplitting), split the large bundle into multiple small files through React.lazy() or build tools, and load it as needed to reduce the first download; 2. Remove unused code (TreeShaking), use the ES6 module mechanism to clear "dead code" to ensure that the introduced libraries support this feature; 3. Compress and merge resource files, enable Gzip/Brotli and Terser to compress JS, reasonably merge files and optimize static resources; 4. Replace heavy-duty dependencies and choose lightweight libraries such as day.js and fetch
