I am trying to save an array into localstorage and then get it.
localStorage.setItem("savedquestionslist", questions);
console.log(localStorage.getItem(savedquestionslist));
The variable 'questions' is an array.
However I get this error:
ReferenceError: savedquestionslist is not defined.
I still get the error even if I do this:
localStorage.setItem("savedquestionslist", "test");
console.log(localStorage.getItem(savedquestionslist));
Does anyone know what the issue is? Thanks
savedquestionslist needs to be a string.
console.log(localStorage.getItem('savedquestionslist'));
The problem is in your syntax for getItem.
It takes in a string as an argument. You are passing a variable and the error represents that the variable savedquestionslist is not defined.
Change your code to :
localStorage.setItem("savedquestionslist", questions);
console.log(localStorage.getItem("savedquestionslist"));
An example would be
var questions = ['firstQuestion', 'secondQuestion', 'thirdQuestion'];
localStorage.setItem("savedquestionslist", questions);
console.log(localStorage.getItem("savedquestionslist"));
The error you're getting is because you forgot the quotes in the getItem call:
console.log(localStorage.getItem("savedquestionslist"));
// ------------------------------^------------------^
Or you can use literal access:
console.log(localStorage.savedquestionslist);
But in both cases, since local storage only stores strings, I'd use JSON, since otherwise your array won't be saved / retrieved correctly:
localStorage.setItem("savedquestionslist", JSON.stringify(questions));
console.log(JSON.parse(localStorage.getItem("savedquestionslist")) || []);
(The || [] is for if you've never set the item, it provides a default of an empty array.)
