Question

我在表中使用p-autoComplete，一旦选择了一行，我的自动完成应该预先选择当前值..我尝试使用[（ngModel）] =“row.bsaName”但它不起作用。（一旦我点击我的dropwdown，我会看到所有值，我确认我的p-autoComplete下拉列表中存在值）

另请注意我使用了p-calendar，我可以在点击编辑后预先选择当前日期，但不确定为什么自动完成不同

Answer 1

只是为了调和评论中发生的一切。

autocomplete无法按预期运行的原因是因为您[(ngModel)]将row.bsaName绑定到字符串 [suggestions]是对象数组。因此，绑定在这里不起作用。有几种方法可以解决这个问题：

将您数据的row.bsaName或bsaName属性更改为{id, name}的对象，以匹配[suggestions]的数据模型
制作一个字符串数组，例如：bsaNamesArr: string[]，并在您的数据提取上map覆盖data.result以获取name array并分配到bsaNamesArr this.bsaNamesArr = data.result.map(element => element.name)。现在，使用bsaNamesArr作为[suggestions]，也可以在bsaNamesArr中使用(completeMethod)。

如果您使用第二种方法，请务必删除field上的p-autocomplete媒体资源。

Answer 2

您可以使用

 <ng-template></ng-template>

在

内部

 <p-autoComplete></p-autoComplete>

标记，就像我在项目中所做的那样。语法如下：

<p-autoComplete
     pTooltip="'tooltip'"
     [(ngModel)]="student"
     #student_id="ngModel"
     name="student_id"
     [suggestions]="studentsList"
     (completeMethod)="filterStudentsList($event)"
     field="name"
     [size]="30"
     placeholder="Enter Student name"
     [minLength]="1"
     required
     (onSelect)="onSelect($event)">
  <ng-template let-student pTemplate="item">
    {{ student.name }}
  </ng-template>
  <ng-template let-student pTemplate="selectedItem">
    {{ student.id }} {{ student.student_name }}
  </ng-template>

因此，如果您想从选定建议中选择2个值，我们可以使用它。

p-autoComplete预先选择默认值
