AngularJS和HTML5日期输入值 – 如何让Firefox显示可读的日期输入值
AngularJS是一种流行的JavaScript框架,它允许开发者构建动态的、单页面的Web应用程序。HTML5引入了许多新的表单元素,包括日期输入类型,这使得收集和处理日期信息变得更加容易。然而,不同的浏览器对于日期输入的支持程度不同,特别是Firefox,它可能不会以可读的格式显示日期输入值。在本文中,我们将探讨如何在AngularJS和HTML5中处理日期输入,以确保在Firefox浏览器中也能显示出可读的日期值。
示例代码1: 基本的日期输入
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>AngularJS and HTML5 Date Input</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.7.8/angular.min.js"></script>
</head>
<body ng-app="dateApp" ng-controller="dateCtrl">
<input type="date" ng-model="dateValue" />
<script>
angular.module('dateApp', []).controller('dateCtrl', function(scope) {scope.dateValue = new Date().toISOString().split('T')[0];
});
</script>
</body>
</html>
Output:
示例代码2: 使用ng-value设置日期输入的值

<body ng-app="dateApp" ng-controller="dateCtrl">
<input type="date" ng-value="formattedDate" />
<script>
angular.module('dateApp', []).controller('dateCtrl', function(scope) {
var today = new Date();scope.formattedDate = today.getFullYear() + '-' +
('0' + (today.getMonth() + 1)).slice(-2) + '-' +
('0' + today.getDate()).slice(-2);
});
</script>
</body>
</html>

angular.module('dateApp', []).controller('dateCtrl', function(scope) {scope.dateValue = new Date();
scope.formattedDate = '';scope.updateDate = function() {
var date = new Date(scope.dateValue);scope.formattedDate = date.getFullYear() + '-' +
