Hi, it’s OK. this.storage.get('buttonBool').then((data)=>{this.flag=data;}); this.storage.get('buttonBool').then((data)=>{console.log(this.flag);}); But this.storage.get('buttonBool').then((data)=>{this.flag=data;}); console.log(this.flag); why undefined value? How do I use it?

[image] How to get the LocalStorage value out of promise scope ionic-v3 @rapropos but in case I have to do lengthy operation… then this should not be the good practice… right?? And suppose if I am retrieving two or more values from localstorage and using those two or more values for data manipulation inside single function i.e. getData()… then how it could be possible to work with them… If i have start_time and stop_time inside localstorage… i want to use it in the getData() function then how I can retrieve both those localstorage value…to do operation like this… …

storageGet(){ Promise.all([ this.storage.get('name').then((data)=>{this.var=data;}),})]); console.log(this.var.toString()); } ı’m using above but same thing

Same problem: The Promises only resolve after console.log already executed. You have to use .then for Promise.all so the console.log only gets executed after all the inner Promises resolved.

Ok.but I use different function this.attribute undefined ionViewDidLoad(){ this.storageGet();;}

Same problem: You execute stuff in this.storageGet async, then execute console.log directly while it is not yet finished. You have to return the promise in storageGet you get from Promise.all and use then() on storageGet.

[image] Sujan12: x such is? ionViewWillEnter(){ Promise.all([]).then(()=>this.storageGet()); } storageGet(){ this.storage.get('name').then((data)=>{this.var=data;}); }

i think it should be var promise1= this.local.get('id'); var promise2 = this.local.get('name'); Promise.all([promise1, promise2 ]).then((arrayOfResults) => { console.log(arrayOfResults[0]); console.log(arrayOfResults[1]); });

storageGet function console write but ionViewWillEnter console not write ionViewWillEnter(){ this.storageGet();;} storageGet(){ var x0=this.storage.get('name'); Promise.all([x0]).then((arrayOfResults) => { this.var=arrayOfResults[0]; console.log(arrayOfResults[0]); });

As I said in the thread that @auspicious linked to earlier, I think your code would be more performant as well as far easier to read, write, and maintain, if you would just combine all of these properties into a single JSON interface instead of storing them all separately.

I am facing exact same issue do you has a solution to this problem
