如果有 2 个用户,我如何删除此 angular 代码中额外的 3 个下载图标
How do i remove the extra 2 download icons in this angular code if there are 3 users
问:
所以这里是html代码:
<tr *ngFor="let user of users">
<td>
<h6 class="font-medium">{{user.id}}</h6>
</td>
<td>
<h6 class="font-medium">{{user.totalPrice}}</h6>
</td>
<td>
<button type="button" *ngFor="let user of users" (click)="downloadJson(user.id)"<i>icon</i></button></td>
这是打字稿方法:
downloadJson(userId: String) {
const user = this.users.find(u => u.id === userId);
if (user) {
const jsonString = JSON.stringify(user, null, 2);
const blob = new Blob([jsonString], { type: 'application/json' });
const link = document.createElement('a');
link.href = window.URL.createObjectURL(blob);
link.download = `user_data_${userId}.json`; // Include user ID in the file name
document.body.appendChild(link);
link.click();
document.body.removeChild(link);
} else {
console.error(`User with ID ${userId} not found`);
}
我尝试了不同的方法来删除它们,但它没有用,我希望它只显示正确 id 的下载项目

我发现问题出在问题中<button type="button" *ngFor="let user of users" (click)="downloadJson(user.id)"<i>icon</i></button></td>
*ngFor="let user of users"
