我创建了一个离子警报来拒绝请求。我希望用户在点击确认之前输入拒绝请求的原因。然后,我想将此数据保存到数据库中,并设置一个方法(declineRequest)。
该方法正在拒绝请求。问题在于如何将警报“ Notes”输入字段保存到数据库中,以及如何确保只有在单击“ confirm”时才运行拒绝请求方法。
代码如下:
HTML:
<ion-list>
<ion-card *ngFor="let r of requests; let i = index">
<ion-item>
<h2>{{r.userId}}</h2>
<p>{{r.requestDetail}}</p>
<p>{{r.fromDateTime}} to {{r.toDateTime}}</p>
<p>{{r.type}}</p>
</ion-item>
<ion-card-content>
<button class="approve" ion-button icon-left color="secondary" (click)="approveAlert(r.id)">
<ion-icon name="checkmark"></ion-icon>
Approve
</button>
<button class="decline" ion-button icon-left color="danger" (click)="declineAlert(r.id)">
<ion-icon name="close"></ion-icon>
Decline
</button>
</ion-card-content>
</ion-card>
</ion-list>
TS:
declineAlert(requestId) {
const alert = this.alertCtrl.create({
title: 'Confirm Request Declined',
subTitle: 'Notes:',
inputs: [
{
name: "Note",
type: "text",
placeholder: 'Please enter reasons'
}],
buttons: [ { text:"Cancel"
},
{ text: "Confirm",
handler: data => {
console.log(JSON.stringify(data));
console.log(data.Note);
}
}],
cssClass: 'alertCustomCss'
});
alert.present();
console.log(requestId);
let notes = Note;
this.declineRequest(requestId, notes);
}
我尝试了不同的方法,但是似乎无法从拒绝的“便笺”中保存文本。
任何帮助将不胜感激。

尝试使用我的工作代码
let alert = this.alertCtrl.create({
title: 'Confirm Request Declined',
inputs: [
{
type: 'textarea',
name: 'Message',
placeholder: 'Please enter reasons',
},
],
buttons: [
{
text: 'Yes',
handler: data => {
var message = data.Message;
//Here is Api call
}
},
{
text: 'No',
role: 'cancel',
handler: data => {
var message = data.Message;
//Your logic
}
}
]
});
alert.present();

正如Keval指出的那样,您只需要在处理程序内使用方法,如下所示:
declineAlert(requestId) {
const alert = this.alertCtrl.create({
title: 'Confirm Request Declined',
subTitle: 'Notes:',
inputs: [
{
name: "Note",
type: "text",
placeholder: 'Please enter reasons'
}],
buttons: [ { text:"Cancel"
},
{ text: "Confirm",
handler: data => {
this.declineRequest(requestId, data.Note);
// additional steps like pop() page etc
}
}],
cssClass: 'alertCustomCss'
});
alert.present();
}
