【问题描述】:
我有一个 Angular 8 应用程序。我正在使用材料的日期选择器。
但是如果我填写一个日期调用 get api 调用:
searchFor(filterRegistration: FilterByRegistrationDTO) {
// tslint:disable-next-line: max-line-length
console.log(
this.participantService.filterParticipantsByRegistration(1, "Invited", this.startDate.toString()).subscribe(result => {
console.log(this.startDate.toString());
console.log(result);
})
);
模板看起来像这样:
<div>
<mat-form-field class="search-field-input">
<input matInput [matDatepicker]="picker1" placeholder="start datum" [(ngModel)]="startDate" />
<mat-datepicker-toggle matSuffix [for]="picker1"></mat-datepicker-toggle>
<mat-datepicker #picker1></mat-datepicker>
</mat-form-field>
</div>
所以在服务器端日期将显示为:jjjj-MM-dd。
但在客户端,日期必须显示为:dd-MM-jjjj。
但是如果我调用 api 调用:
console.log(
this.participantService.filterParticipantsByRegistration(1, "Invited", this.startDate.toString()).subscribe(result => {
console.log(this.startDate.toString());
console.log(result);
})
);
然后我会得到这个错误:
core.js:12584 ERROR
HttpErrorResponse {headers: HttpHeaders, status: 400, statusText: "Bad Request", url: "https://dev-engine.mijnhep.nl/api/medical/organisa…GMT%2B0200%20(Central%20European%20Summer%20Time)", ok: false, …}
error:

__proto__: HttpResponseBase
所以我的问题是。如何在客户端填写正确的日期格式。这样就不会报错了?
谢谢
【问题讨论】:
-
您可以使用 javascript 来解析格式或使用像 moment.js 或日期函数这样的库来轻松地为您包装它。
-
谢谢。但是一个例子会很好
-
为什么不格式化提交的日期??而不是 this.startDate.toString() 正确格式化日期?
-
是的,好的。但是格式??你能举个例子吗?会很好
