js save and load an array of different types into localstorage
var myArray = [1,"word",23,-12,"string"];//your list of values, they can be strings or numbers //SAVING function save(a,b,c,d,e) {//the number of parameters you add is how many items you save var itemArray = [a,b,c,d,e];//number of items here must be the same as number of parameters var keyArray = ["one","two","three","four","five"];//must be same length as itemArray for (var i = 0; i < keyArray.length; i++) { if (typeof(itemArray[i]) === "number") { itemArray[i] = "+"+itemArray[i];//leave a reminder that it was a number } if (typeof(itemArray[i]) !== undefined) { localStorage.setItem(keyArray[i],itemArray[i]);//only add a value to the current key if it's not undefined } } } //to use the function (whenever you want to save): save.apply(this, myArray);//assuming that myArray is the array you want to set //LOADING function load() { var list = []; var keyArray = ["one","two","three","four","five"]; for (var i = 0; i < keyArray.length; i++) { var item = localStorage.getItem(keyArray[i]); if (item.charAt(0) == "+") { item = parseFloat(item.substring(1)); } list.push(item); } return list; } //to use the function myArray = load();//sets your array back to how it was when you saved it
