我有自动填充输入
<div formArrayName="addresses">
<div class="row"
*ngFor="let itemrow of searchForm.controls.addresses.controls; let i=index"
[formGroupName]="i">
<mat-form-field>
<input type="text"
class="form-control" id="address"
formControlName="address"
matInput
[matAutocomplete]="auto"
(keyup)="getESRI($event.target.value)"
(focusout)="bindLocation($event.target.value)">
<mat-autocomplete #auto="matAutocomplete">
<mat-option *ngFor="let option of testLocation"
[value]="option.text">
{{ option.text }}
</mat-option>
</mat-autocomplete>
</mat-form-field>
</div>
</div>
"testlocation":[{"text":"Euronet","magicKey":"dHA9MSNubT1FdXJvbmV0I2NzPTE5OjExI3NjPURFVQ==","isCollection":true},{"text":"Euronet","magicKey":"dHA9MSNubT1FdXJvbmV0I2NzPTE5OjExI3NjPURFVQ==","isCollection":true}]
当我尝试添加值[value]="option.magicKey
时,当我选择选项时,它会显示在输入option.magicKey
中。我只需要option.magicKey
作为值,option.text
作为输入选项。否则,如何将option.magicKey
作为参数添加到bindLocation($event.target.value)
函数?

MatAutoComplete具有名为homebrew/core
的输入。其中,您需要传递一个将选项的控制值映射到其显示值的函数。
displayWith
以下是使用密钥
返回值的函数<mat-form-field>
<input
matInput
placeholder="Select a value"
[formControl]="form.controls.enumField"
[matAutocomplete]="autoComplete">
<mat-autocomplete
#autoComplete="matAutocomplete"
[displayWith]="valueMapper"> <-- Using displayWith here
<mat-option
*ngFor="let enum of enumerationObservable | async"
[value]="enum.key">
{{ enum.value }}
</mat-option>
</mat-autocomplete>

将 [displayWith] 属性与自动完成字段一起使用。
HTML文件
<input
type="text"
placeholder="Address"
mdInput
formControlName="address"
[mdAutocomplete]="auto"
(keyup)="onKeyUp()">
<md-autocomplete
#auto="mdAutocomplete"
[displayWith]="displayFn">
<md-option *ngFor="let option of options"
[value]="option">
{{ option.text }}
</md-option>
</md-autocomplete>

<mat-option>
有事件 onSelectionChange ,通过此事件,您可以调用任何函数并绑定选项对象中的所有内容
(onSelectionChange)="bindLocation(option.text, option.magicKey)"
