Angular Material DatePicker 自动完成 [英] Angular Material DatePicker Autocomplete

问题描述

尝试实现一个搜索栏，您可以在其中按项目名称或日期进行搜索.只是想知道是否有办法禁用日期选择器自动完成功能?

trying to implement a searchbar where you can search by the item's name or by a date. just wanted to know if there's a way to disable the datepicker autocomplete?

问题是:- 如果我按日期搜索，那很好- 如果我按名称进行搜索就可以了...直到我失去搜索输入的焦点，然后它会自动完成一个日期

problem is : - if i do a search by date, it's fine - if i do a search by name it's ok... untill i loose focus of search input, then it autocomplete with a date

示例:如果我搜索一个包含 1234 的项目并且搜索输入的焦点松散，它将以 01/01/1234 完成并使用它进行研究...

example : if i search an item with 1234 in it and loose focus of the search input, it will complete with 01/01/1234 and do the research with it...

   <mat-form-field id="search">
      <input i18n-placeholder="Search@@searchBar" matInput placeholder="Search..."
      [matDatepicker]="picker" (dateInput)="searchDate($event)"  #input />
      <mat-icon matPrefix>search</mat-icon>
    </mat-form-field>

    <span>
      <mat-datepicker-toggle [for]="picker"></mat-datepicker-toggle>
      <mat-datepicker #picker ></mat-datepicker>
    </span>

也许我只是做错了...?问候j0w

Maybe i'm just doing it the wrong way...? Regards j0w

推荐答案

您应该创建一个隐藏的输入，绑定到日期选择器，并在用户选择日期时更新自动完成的值.另一方面，第一个输入不应绑定到日期选择器，因为它是自动完成的.这是一个stackblitz 示例 :

You should create an hidden input, bound to the datepicker, and update the value of the autocomplete when the user choses a date. The first input, on the other side, should not be bound to the datepicker, since it is an autocomplete. Here is a stackblitz example :

toFormattedDate(iso: string) {
  const date = new Date(iso);
  console.log(date);
  return `${date.getDate()}/${date.getMonth() + 1}/${date.getFullYear()}`;
}

<mat-form-field>
  <input matInput #autocomplete placeholder="Choose a date">
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker></mat-datepicker>
</mat-form-field>

<input type="hidden" [matDatepicker]="picker" placeholder="Choose a date" (dateChange)="autocomplete.value = toFormattedDate($event.value)">
