Question

出于某种原因，无论我使用哪种格式来构造ngSwitch，唯一有效的指令就是* ngSwitchDefault。

这是我的代码：

tf = TfidfVectorizer(tokenizer=normalize, decode_error = 'ignore',max_features=10000)

tfidf_matrix = tf.fit_transform(aux['enlarged_description'])

#cosine_similarities = linear_kernel(tfidf_matrix, tfidf_matrix)
X = pairwise_distances(tfidf_matrix, metric = metrics,n_jobs = -2 )

问题在于，在评估字符串时，必须将其放在单引号中，因此修复非常简单：

<div class="icon-group" [ngSwitch]="published?.availableOn">
                <mat-icon *ngSwitchCase=" 'Android' " fontSet="fontawesome" fontIcon="fa-android" class="green-icon"></mat-icon>
                <mat-icon *ngSwitchCase=" 'Windows' " fontSet="fontawesome" fontIcon="fa-windows" class="blue-icon"></mat-icon>
                <mat-icon *ngSwitchCase=" 'iOS' " fontSet="fontawesome" fontIcon="fa-apple"></mat-icon>
                <mat-icon *ngSwitchCase=" 'Web' " fontSet="fontawesome" fontIcon="fa-internet-explorer"></mat-icon>
                <ng-container *ngSwitchCase=" 'AndroidiOS' ">
                        <mat-icon fontSet="fontawesome" fontIcon="fa-android" class="green-icon"></mat-icon>
                        <mat-icon fontSet="fontawesome" fontIcon="fa-apple"></mat-icon>
                </ng-container>
                <mat-icon *ngSwitchDefault  fontSet="fontawesome" fontIcon="fa-internet-explorer"></mat-icon>  

</div>

AngularX ngSwitch始终使用ngSwitchDefault
