Localstorage listing
I made my own function using this:
function save(title, url)
{
for (var i = 1; i < localStorage.length; i++)
{
localStorage["saved-title_" + i + ""] = title;
localStorage["saved-url_" + i + ""] = url;
}
}
function listFavs()
{
for (var i = 1; i < localStorage.length; i++) {
console.log(localStorage["saved-fav-title_" + i + ""]);
}
}
save () happens when someone clicks on this:
onclick="save(\'' + title + '\', \'' + tab.url + '\');"> ' + title + '</a>';
However ... it doesn't show the localStorages saved, how should I get it to work?

Perhaps this is because you are using a key 'saved-title_' + i
to store the value and 'saved-fav-title_' + i
to retrieve it?
The difference lies in the fav - part .
And your localStorage list should throw errors, since there is no guarantee that all the elements in it have a key that matches the pattern 'saved-fav-title_' + i
- in fact, this is not guaranteed in the way that you yourself enter keyed elements in the form 'saved-url_'+ i
.
So, if you want to list the elements correctly with a key matching the pattern, use
function listFavs(){
var key;
for (var i = 0, len = localStorage.length; i < len; i++){
key = localStorage.key(i);
if ((/^saved-fav-title_/).test(key)) {
console.log(localStorage.getItem(key);
}
}
}
