javascript - For loop through Array only shows last value

Question

I'm trying to loop through an Array which then uses innerHTML to create a new

element for every entry in the array. Somehow my code is only showing the last value from the array. I've been stuck on this for a few hours and can't seem to figure out what I'm doing wrong.

window.onload = function() {

// Read value from storage, or empty array
var names = JSON.parse(localStorage.getItem('locname') || "[]");
var i = 0;

    n = (names.length);
    for (i = 0; i <= (n-1); i++) {
        var list = names[i];
        var myList = document.getElementById("list");
        myList.innerHTML = "<li class='list-group-item' id='listItem'>"+ list + "</li>" + "<br />";
    }
}

I have a UL with the id 'list' in my HTML.

Change your for loop:

for (i = 0; i <= (n-1); i++) {
    var list = names[i];
    var myList = document.getElementById("list");
    myList.innerHTML += "<li class='list-group-item' id='listItem'>"+ list + "</li>" + "<br />";
}

Use += instead of =. Other than that, your code looks fine.
