使用nativescript开发iphone应用程序。我正在尝试使用ngFor显示2个列表以遍历数组。
例如...我的数据看起来像这样
对象(this.metroGroup):
{
YL: [{
"Line": "Shady Grove",
"Min": 2,
}, {
"Line": "Glenmont",
"Min": 4,
}],
GR: [{
"Line": "Blue Field",
"Min": 6,
}, {
"Line": "Green Line",
"Min": 8,
}]
}
模板代码:
<ScrollView row="1">
<StackLayout *ngIf="metroGroup.GR">
<Label text="Green" class="train-stop-label"></Label>
<StackLayout *ngFor="let metro of metroGroup.GR" class="list-group-item">
<Label class="h3" [text]="metro.Line"></Label>
<Label class="h3" [text]="metro.Min"></Label>
</StackLayout>
</StackLayout>
<StackLayout *ngIf="metroGroup.YL">
<Label text="Yellow" class="train-stop-label"></Label>
<StackLayout *ngFor="let metro of metroGroup.YL" class="list-group-item">
<Label class="h3" [text]="metro.Line"></Label>
<Label class="h3" [text]="metro.Min"></Label>
</StackLayout>
</StackLayout>
</ScrollView>
现在仅显示黄色。。。似乎黄色堆叠在绿色列表的顶部。对如何同时显示两者有什么想法?

您需要一个父版式。我为您创建了一个示例playground。
<ScrollView class="page">
<StackLayout class="home-panel">
<StackLayout *ngIf="metroGroup.GR">
<Label text="Green" class="train-stop-label"></Label>
<StackLayout *ngFor="let metro of metroGroup.GR" class="list-group-item">
<Label class="h3" [text]="metro.Line"></Label>
<Label class="h3" [text]="metro.Min"></Label>
</StackLayout>
</StackLayout>
<StackLayout *ngIf="metroGroup.YL">
<Label text="Yellow" class="train-stop-label"></Label>
<StackLayout *ngFor="let metro of metroGroup.YL" class="list-group-item">
<Label class="h3" [text]="metro.Line"></Label>
<Label class="h3" [text]="metro.Min"></Label>
</StackLayout>
</StackLayout>
</StackLayout>
</ScrollView>
