我遇到的問題是不顯示顯示和隱藏功能。問題是能夠爲所選按鈕獲取正確的索引。下面我抓住第二個數組的索引。如果用戶要選擇每個currentItems數組的第一個項目,則所有的第一個項目都會打開和關閉。我想要的只是被選擇關閉和打開的那個。點擊resultInfo數組,我想要顯示itemInfo。隱藏並顯示項目點擊存儲在多個陣列 - ionic 2+/angular 2+
HTML
<div *ngFor="let a of currentItems">
<ion-item-sliding id="rightdiv" *ngFor="let b of a.resultInfo; index as i">
<button ion-item (click)="toggleGroup(i)" [ngClass]="{active: isGroupShown(i)}" class="destInfo">
<h3>click me</h3>
</button>
<ion-item [class.hidden]="!isGroupShown(i)" *ngFor="let c of b.itemInfo">
<ion-label>{{c.name}}</ion-label>
</ion-item>
</ion-item-sliding>
</div>
TS
shownGroup = null;
toggleGroup(group) {
if (this.isGroupShown(group)) {
this.shownGroup = null;
} else {
this.shownGroup = group;
console.log(this.shownGroup, 'SHOWN GROUP HERE')
}
}
isGroupShown(group) {
return this.shownGroup === group;
};
DATA
currentItems = [
{
"time": "a some time",
"resultInfo": [
{
"about": "some place",
"itemInfo": [
{
"name": "someName"
},
]
}
]
},
{
"time": "some time",
"resultInfo": [
{
"about": "some place",
"itemInfo": [
{
"name": "someName"

}

}

在您的功能 this.c = currentItems [index] .resultInfo [0] .itemInfo [0] – Swoox
