【问题描述】:
我遇到的问题是没有显示显示和隐藏功能。问题是能够获取所选按钮的正确索引。下面我正在获取第二个数组的索引。如果用户选择每个 currentItems 数组的第一项,则所有第一项将打开和关闭。我想要的只是选择关闭和打开的那个。单击 resultInfo 数组时,我希望显示 itemInfo。
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;
};
数据
currentItems = [
{
"time": "a some time",
"resultInfo": [
{
"about": "some place",
"itemInfo": [
{
"name": "someName"
},
]
}
]
},
{
"time": "some time",
"resultInfo": [
{
"about": "some place",
"itemInfo": [
{
"name": "someName"
},
]
}
]
}
]

在你的函数中 this.c = currentItems[index].resultInfo[0].itemInfo[0]
