Localstorage: Count how many values in key when using stringify

rated 0 times [ 175] [ 4] / answers: 1 / hits: 16902 / 13 Years ago, fri, november 11, 2011, 12:00:00

How can I count how many different values I have in 1 localstorage key.

For example:

This is my localstorage:

[{id:item-1,icon:google.com},{id:item-2,icon:youtube.com}]

For this example I'd like an alert of 2 different values. So basically I want to count the {}..

Is that possible?

localStorage is an object, so just localStorage.length gives you the number of entries.

However I think I might be misunderstanding you. Do you mean you have one key, and that key's value is a JSON.stringify'd object? If so, you could do JSON.parse(localStorage.keyname).length to unserialise the value and count how many there are in there.
