这段代码中有一个错误
<img src="../../../assets/gms-logo.png" alt="logo" routerLink="/overview" alt="website icon">
但当我检查资产文件夹时,gms-logo.png仍在那里,在angular-cli.json中,资产也在那里.路径也是正确的.
Has the program started searching even if the user is still not focused on the input type? How do I fix this?
<input type="text" placeholder="Search" (keyup)="onSearch($event.target.value)">
<div class="suggestion" *ngIf="results.length > 0">
<div *ngFor="let result of results ">
<a href="" target="_blank">
{{ result.name }}
</a>
</div>
</div>
以下是我的组件
results: Object;
onSearch(name) {
this.search
.searchEmployee(name)
.subscribe(
name => this.results = name,//alert(searchName),this.route.navigate(['/information/employees/']),error => alert(error),);
}
解决方法
您需要将结果变量初始化为数组.
在您的组件中,添加：
results = [];
另一种选择是更改建议div的* ngIf语句以检查结果是否已定义：
<div class="suggestion" *ngIf="results">
<div *ngFor="let result of results ">
<a href="" target="_blank">
{{ result.name }}
</a>
</div>
</div>
