如何在 Ionic 2 的警报对话框中设置警报消息的文本字段?
How do I set text field for alert message in the alert dialog in Ionic 2?
我正在使用 Firebase 收到推送通知并将其显示在警告框中。现在我想在文本字段中显示我收到的消息,以便用户可以编辑 message.I 也想在控制台中输出消息。
pushObject.on('notification').subscribe((notification: any) => {
if (notification.additionalData.foreground) {
let youralert = this.alertCtrl.create({
title: 'New Push notification',
message: notification.message,
buttons: [
{
text: 'Cancel',
role: 'cancel',
handler: () => {
console.log('Cancel clicked');
}
},
{
text: 'Okay',
handler: () => {
console.log('Okay clicked');
}
}
]
});
Alert 界面上有一个 inputs
属性,它的工作原理与 buttons
非常相似。它是一个对象数组,您有一个输入 value
属性 来设置所需的值。
因为我不知道你想在哪里记录你的值,如果它是来自服务器的值或编辑后的值,我会显示两者。
pushObject.on('notification').subscribe((notification: any) => {
if (notification.additionalData.foreground) {
console.log('push message', notification.message);
let youralert = this.alertCtrl.create({
title: 'New Push notification',
inputs: [{
placeholder: 'Your placeholder..',
type: 'text',
name: 'yourInputName, // Name to get it in your handler callback
value: notification.message
}],
message: notification.message,
buttons: [
{
text: 'Cancel',
role: 'cancel',
handler: () => {
console.log('Cancel clicked');
}
},
{
text: 'Okay',
// you'll need to get the input data, so pass a parameter to the callback
handler: (data) => {
// here's the value user has edited in the input
console.log('Edited message', data.yourInputName);
console.log('Okay clicked');
}
}
]
});
