Here is the code snippet I am using:
for(var i=0; i < localStorage.length; i++) {
var subjects = [];
var key, value;
key = localStorage.key(i);
value = localStorage.getItem(key);
var keysplit = key.split(".");
if(keysplit[keysplit.length] == "subj") {
subjects.push(value);
}
}
I am encountering an issue where my code is not correctly selecting all the keys that end with .subj. Any suggestions on how to fix this problem?
The length attribute provides the count of elements in the array, where indexing starts at zero meaning there is no element at that index.
To access the last item, simply use length - 1:
if (keysplit[keysplit.length - 1] === "subj") {
Here are some other options to consider:
if(key.substr(key.lastIndexOf('.')) == ".subj")
//or
var suffix = '.subj';
if(key.lastIndexOf(suffix) == key.length - suffix.length)
