I am attempting to utilize JSON.parse and JSON.stringify to store and update an array in local storage. However, the process doesn't seem to be functioning as expected.
let existingArray = JSON.parse(localStorage.getItem("yesArray"));
existingArray.push("yes");
localStorage.setItem("yesArray", JSON.stringify(existingArray));
Is there something fundamentally incorrect with my approach here?
This issue appears to arise when passing the key of local storage without enclosing it in quotation marks.
When retrieving data from local storage, make sure to provide the key as an argument since it stores information in the format of key/value pairs.
itemsList = JSON.parse(localStorage.getItem("itemsList"));
Are the quotes missing around yesArray in the initial line?
yesArray = JSON.parse(localStorage.getItem('yesArray'));
Here is a quick example:
var yesArray = [];
localStorage.setItem('yesArray', JSON.stringify(yesArray));
yesArray = JSON.parse(localStorage.getItem('yesArray'));
yesArray.push('yes');
localStorage.setItem('yesArray', JSON.stringify(yesArray));
JSON.parse(localStorage.getItem('yesArray')); // Produces ["yes"]
