您可以使用Document1伪类选择器。
例如：
export interface AttachmentForm {
name: string;
isDuplicate: boolean;
}
ngOnInit() {
this.attachmentForms = [
{name: 'Document1', isDuplicate: false},
{name: 'Document2', isDuplicate: false},
{name: 'Document1', isDuplicate: false},
{name: 'Document3', isDuplicate: false},
];
this.findDuplicates() ;
}
findDuplicates() {
const newArr: AttachmentForm[] = [];
this.attachmentForms.forEach((item, index) => {
if (newArr.findIndex(i => i.name === item.name) === -1) {
item.isDuplicate = false;
} else {
item.isDuplicate = true;
}
newArr.push(item);
});
this.attachmentForms = newArr;
}
将获得重点关注的输入。

以下是使用纯Private Sub Form1_Load(ByVal sender As Object, e As EventArgs) Handles MyBase.Load
Combobox1.DropDownStyle = ComboBoxStyle.DropDown
End Sub
Private Sub ComboBox1_KeyDown(sender As System.Object, e As System.Windows.Forms.KeyEventArgs) Handles ComboBox1.KeyDown
If e.KeyCode = Keys.Enter Then
ComboBox1.Items.Add(Combobox1.Text)
ComboBox1.SelectedIndex = ComboBox1.Items.Count - 1
End If
End Sub
