我正在制作日历。问题是当我第一次加载时，日期没有显示。如果我转到下个月并再次返回到上个月，那么日期就会显示并且工作正常。假设当前月份是十月，那么当您加载页面时，只会显示当前月份十月。无日期。现在，单击向右箭头转到 11 月，然后单击向左箭头在 10 月再次返回。将显示日期。请检查我的 fiddle 和代码:-
datepicker = angular.module('datepicker', []);
datepicker.controller('dateTimePicker', ['$scope', function($scope){
console.log('alive');
var date = new Date();
var months = [],
monthNames = ["Jan", "Feb", "Mar", "Apr", "May", "Jun",
"Jul", "Aug", "Sep", "Oct", "Nov", "Dec"
];
for (var i = 0; i <= 12; i++) {
months.push(monthNames[date.getMonth()] + ' ' + date.getFullYear());
date.setMonth(date.getMonth() + 1);
}
$scope.year =2015;
$scope.changeMonth = function(steps) {
if ($scope.monthIndex + steps >= 0 &&
$scope.monthIndex + steps <= 12
) {
$scope.dateValues = [];
$scope.monthIndex = $scope.monthIndex + steps;
$scope.monthName = $scope.months[$scope.monthIndex];
var date = new Date();
console.log(date.getMonth());
var offset = date.getMonth()
console.log($scope.monthIndex);
var offsetDate = offset + $scope.monthIndex;
$scope.nDays = new Date( $scope.year, offsetDate+1, 0).getDate();
console.log(offsetDate+1);
console.log(new Date( $scope.year, offsetDate, 1));
for (i = 1; i <= $scope.nDays; i++) {
var d = new Date();
$scope.dateValues.push(new Date($scope.year, offsetDate, i));
}
}else{console.log("missed")}
};
$scope.monthIndex = 0;
$scope.months = months;
$scope.monthName = months[0];
}]);fiddle 链接:- https://jsfiddle.net/abhijitloco/fxbmpetu/15/
最佳答案
您可以使用 ng-init 来调用您的changeMonth 函数。
<body ng-controller="dateTimePicker" ng-init="changeMonth(0)">
或者您可以在设置月份来设置 $scope.dateValues 变量时在 Controller 中调用它。无论哪种方式，这个变量都需要初始化，因为它不是您当前的代码。
$scope.monthIndex = 0;
$scope.months = months;
$scope.monthName = months[0];
$scope.changeMonth(0);
