This is my third post on angular. I want to display a list of type candidates: Candidate[]. I am currently displaying it in the view using an *ngFor like this:
<ul>
<li *ngFor="let candidate of candidates">
{{ candidate.name }}
</li>
</ul>
However, i need to filter the candidates to fit the user search with a function :
filterResults(queryString): void {
this.candidatesService.filterCandidates(queryString).subscribe(candidates => this.filteredCandidates = candidates);
this.filteredCandidates = this.filteredCandidates.filter(candidate => candidate.name == queryString);
}
The problem is, the function is triggered on keyup of an input box. So, the filtered candidates array value is changing based on input.
Does anybody know how do i update the template view too, to only display the newly only the results in the updated array ?
在*ngFor
创建temp并将您的候选者存储在temp[]
,该条件在不搜索条件时和在this.filteredCandidates
过程中使用时将得到this.filteredCandidates
并将其推入temp[]
并显示。
