我已经传递了两个回调函数成功和错误,使用 then 方法从 ajax 调用返回。现在我无法在成功/错误方法中获取 Ember 组件对象。
import Ember from 'ember';
export default Ember.Component.extend({
data:null,
issueType:'',
description:null,
prepareSubmitRaiseIssueModal:function(){
var data = this.get('data');
this.set('ticket.category',data.category);
this.set('ticket.name',this.get('session.currentUser.first_name'));
this.set('ticket.phone',this.get('session.currentUser.phone'));
this.set('ticket.groupId',data.groupId);
this.set('ticket.ownerId',this.get('session.currentUser.id'));
this.set('ticket.oyoId',this.get('session.currentOwnerHotelOyoId'));
this.set('ticket.ticketRaisedBy','owner');
this.set('ticket.bookingId',data.bookingId);
this.set('ticket.subType',data.subType);
this.set('ticket.subSubIssue',data.subSubIssue);
this.set('ticket.email',this.get('ticket.oyoId')+'@oyoproperties.com');
this.set('ticket.subject',this.get('ticket.oyoId')+' : '+this.get('ticket.category'));
this.set('ticket.description',this.get('description'));
},
success:function(){
console.log(this.get('description'));
},
error:function(){
console.log(this.get('description'));
},
actions :{
submitIssue:function(){
this.prepareSubmitRaiseIssueModal();
this.get('ticket').submitRaiseIssue().then(this.success,this.error);
//this.send('closeRaiseIssueModal');
},
closeRaiseIssueModal:function(){
this.sendAction('closeRaiseIssueModal');
}
}
});
如果不是传递命名函数,而是传递匿名函数,我能够获取 Ember 组件对象。
submitIssue:function(){
var self = this;
this.prepareSubmitRaiseIssueModal();
this.get('ticket').submitRaiseIssue().then(function(response){
console.log(self.get('description'));
},
function(err){
console.log(self.get('description'));
});
//this.send('closeRaiseIssueModal');
},
有什么方法可以获取 Ember 组件对象对前一种情况的引用?
哇说
意大利面。
prepareSubmitRaiseIssueModal:function(){
var data = this.get('data');
this.set('ticket.category',data.category);
this.set('ticket.name',this.get('session.currentUser.first_name'));
this.set('ticket.phone',this.get('session.currentUser.phone'));
this.set('ticket.groupId',data.groupId);
this.set('ticket.ownerId',this.get('session.currentUser.id'));
this.set('ticket.oyoId',this.get('session.currentOwnerHotelOyoId'));
this.set('ticket.ticketRaisedBy','owner');
this.set('ticket.bookingId',data.bookingId);
this.set('ticket.subType',data.subType);
this.set('ticket.subSubIssue',data.subSubIssue);
this.set('ticket.email',this.get('ticket.oyoId')+'@oyoproperties.com');
this.set('ticket.subject',this.get('ticket.oyoId')+' : '+this.get('ticket.category'));
this.set('ticket.description',this.get('description'));
},
怎么样
prepareSubmitRaiseIssueModal:function(){
var data = this.get('data');
var ticket = this.get('ticket')
ticket.setProperties({
'category': data.category,
'name': ...
})
},
要传递引用,您可以使用
promise.then(function() {
this.mysuccess();
}.bind(this), function() {
this.myerror();
}.bind(this))
const self = this;
promise.then(function() {
self.blah();
});
promise.then(result => {
this.blah();
})
在您的情况下,我会编写一个实用程序JS文件来显示通知。
并亲自处理每个承诺的成功,并让错误以一般的错误方法处理。
实用程序/通知.js
function reportError(error) {
displayNotification('error', getErrorMessage(error));
}
import reportError from 'utils/notifications';
export default Ember.Controller.extend({
....
promise.then(result => {
// Do custom stuff with result;
}, reportError);
....
});
在承诺中承诺
return promise1.then(x => {
return promise2.then(x2 => {
return promise3 ... etc
})
}).catch(reportError); // Single hook needed but u need to return promises
