I'd like to retrieve the name and the date of created tasks. I managed to put the value taskMessage in local storage, but I don't know how to add taskName as well. This is the code I currently have :
$(document).ready(function () {
var i = 0;
for (i = 0; i < localStorage.length; i++) {
var taskID = "task-" + i;
$('.task-container').append("<li class='item-content' id='" + taskID + "'>" + localStorage.getItem(taskID) + "</li>");
}
$('.floating-button').on('click', function () {
myApp.prompt('', 'Add Task', function (task) {
if (task !== "") {
myApp.prompt('', 'Choose time', function (time) {
var d1 = new Date();
d1.setHours(time, 0, 0, 0);
var hour = d1.getHours();
if (time > 0 && time < 25) {
var d2 = new Date();
var currenttime = d2.getHours();
if (time > currenttime) {
var taskID = "task-" + i;
var taskMessage = hour;
var taskName = task;
localStorage.setItem(taskID, taskMessage);
var newtask = '<li class="item-content ' + taskID + '"><div class="item-inner"><div class="item-title" >' + taskName + '</div><div class="item-after"> ' + taskMessage + ':00</div> </div></li>';
var taskitem = $('#' + taskID);
$('.task-container').append(newtask);
}
else {
myApp.addNotification({
message: 'Please choose a valide time period'
});
}
}
else {
myApp.addNotification({
message: 'Please choose a value between 1 and 24'
});
}
});
}
else {
myApp.addNotification({
message: 'Please enter a valid name'
});
}
});
});
});

Reset to default 8First you should get the data into a variable
var getData =
{
"firstData":"data1",
"secondData":"data2",
"thirdData": "data3"
}
Then you can set the above data's in localStorage...
localStorage.setItem('dataKey', JSON.stringify(getData ));
Then get....
var val = localStorage.getItem('dataKey');
Enjoy!!!
If you want to store two different values in localStorage then you can do somrthing like this :
setItem in localStorage two times with different keys.
localStorage.setItem("message", taskMessage); localStorage.setItem("name", taskName);Store both the values in an object.
var obj = { "message": taskMessage, "name": taskName } var val = localStorage.setItem("task", obj);
typeof val: string
Value of val: [object Object]
setItem method convert the input to a string before storing it.
Try this :
// Put the object into storage
localStorage.setItem('task', JSON.stringify(obj));
// Retrieve the object from storage
var val = localStorage.getItem('obj');
console.log('retrievedValue: ', JSON.parse(val));
You can easily store values in localstorage using following example.
//Save the values to Localstorage
localStorage.setItem('first','firstvalue');
localStorage.setItem('second','secondvalue');
//Retrieve the values from localstorage
localStorage.getItem('first')
//"firstvalue"
localStorage.getItem('second')
//"secondvalue"
localStorage saves item key&value as string,so you call setItem with an object/json object,you must serialize json to string by JSON.stringify() method.when you get value you need parse string as json object using JSON.parse() method.
Test
test(`can't retrieve json from localStorage if raw json data saved`, () => {
localStorage.setItem('foo', {foo: 'bar'});
expect(localStorage.getItem('foo')).toEqual('[object Object]');
});
test(`retrieve json value as string from localStorage`, () => {
localStorage.setItem('foo', JSON.stringify({foo: 'bar'}));
let json = JSON.parse(localStorage.getItem('foo'));
expect(json.foo).toEqual('bar');
});
test(`key also be serialized`, () => {
localStorage.setItem({foo: 'bar'}, 'value');
expect(localStorage.getItem('[object Object]')).toEqual('value');
});
test('supports bracket access notation `[]`', () => {
localStorage.setItem('foo', 'bar');
expect(localStorage['foo']).toEqual('bar');
});
test('supports dot accessor notation `.`', () => {
localStorage.setItem('foo', 'bar');
expect(localStorage.foo).toEqual('bar');
});
