[英]angularjs ui bootstrap datepicker unexpectedly adding a day
美好的一天,默認情況下,我使用momentjs在ui引導日期選擇器輸入字段中以YYYY-MM-DD這樣的格式設置日期。 日期以我想要的格式正確顯示。 當我選擇其他日期時,它會正確顯示輸入字段,但是當我決定控制台日志時,會在其中添加一天的值以及時區(T00:00:00.000Z)。 這是我的HTML的片段
<div class="row">
<div class="col-md-6">
<label>Drawdown Ent. Date <span style="color: red;">*</span></label>
<input type="text"
class="form-control"
datepicker-popup="yyyy-MM-dd"
ng-model="bookloan.drawdown_ent_date"
is-open="drawdown_ent_date.open"
ng-click="drawdown_ent_date.open = true"
datepicker-options="entDateOptions"
date-disabled="disabled(date, mode)"
close-text="Close" />
</div>
</div>
這是我的JavaScript代碼的片段:
$scope.bookloan.drawdown_ent_date = moment().format("YYYY-MM-DD");
是什么原因造成的? 提前致謝..
我通過使用以下指令找到了解決問題的方法:
app.directive('datepickerLocalDate', ['$parse', function ($parse) {
var directive = {
restrict: 'A',
require: ['ngModel'],
link: link
};
return directive;
function link(scope, element, attr, ctrls) {
var ngModelController = ctrls[0];
// called with a JavaScript Date object when picked from the datepicker
ngModelController.$parsers.push(function (viewValue) {
// undo the timezone adjustment we did during the formatting
viewValue.setMinutes(viewValue.getMinutes() - viewValue.getTimezoneOffset());
// we just want a local date in ISO format
return viewValue.toISOString().substring(0, 10);
});
// called with a 'yyyy-mm-dd' string to format
ngModelController.$formatters.push(function (modelValue) {
if (!modelValue) {
return undefined;
}
// date constructor will apply timezone deviations from UTC (i.e. if locale is behind UTC 'dt' will be one day behind)
var dt = new Date(modelValue);
// 'undo' the timezone offset again (so we end up on the original date again)
dt.setMinutes(dt.getMinutes() + dt.getTimezoneOffset());
return dt;
});
}
}]);
並將指令名稱放在輸入元素中:
<div class="col-md-6">
<label>Drawdown Ent. Date <span style="color: red;">*</span></label>
<input type="text"
class="form-control"
datepicker-local-date
datepicker-popup="yyyy-MM-dd"
ng-model="bookloan.drawdown_ent_date"
is-open="drawdown_ent_date.open"
ng-click="drawdown_ent_date.open = true"
datepicker-options="entDateOptions"
date-disabled="disabled(date, mode)"
close-text="Close" />
</div>
</div>
