firebase - How to wait value in Ionic 2 -

-



i'm trying wait value may change after execute "this.bookmarlist.take(1).subscribe(..."

my problem when run application, execute second if statement "if(found==false)" before execute subscribe.

this code may found thing wrong or need add additions solve problem.

let loader = this.loadingctrl.create({   content: "", }); let found=false; loader.present().then(()=>{     this.bookmarklist.take(1).subscribe(data=>{         data.foreach(b=>{             if(b.nid==this.appservice.id && b.url==url){                 let alert = this.alertctrl.create({                 title: 'already bookmarked',                     subtitle: 'this note image bookmarked',                     buttons: ['ok']                 });                 alert.present();                 found=true;             }         })     }) }).then(()=>{     if(found==false){         this.afd.list('/bookmark/').push({             uemail: this.userservice.email,             nid: this.appservice.id,             url: url,             date: datex         });         let alert = this.alertctrl.create({             title: 'bookmarked successfully',             subtitle: 'this note image has been bookmarked successfully',                 buttons: ['ok']         });         alert.present();     } }).then(_=>{     loader.dismiss(); })

i find solution

let loader = this.loadingctrl.create({   content: "", }); let found=false; loader.present().then(_=>{     this.bookmarklist.take(1).subscribe(data=>{         data.foreach(b=>{             if(b.nid==this.appservice.id && b.url==url){                 let alert = this.alertctrl.create({                     title: 'already bookmarked',                     subtitle: 'this note image bookmarked',                     buttons: ['ok']                 });                 alert.present();                 found=true;             }         })         if(found==false){             this.afd.list('/bookmark/').push({                 uemail: this.userservice.email,                 nid: this.appservice.id,                 url: url,                 date: datex             });             let alert = this.alertctrl.create({                 title: 'bookmarked successfully',                 subtitle: 'this note image has been bookmarked successfully',                 buttons: ['ok']             });             alert.present();         }         //return     }) }).then(_=>{     loader.dismiss(); })
