I have persistent checkboxes which represent the days of the week. I was able to store these values in localStorage
in an array so that they stay after refresh.
What I want to know is how can I output "Weekday" or "Weekend" based on the selection of the days? For example a user selects "Monday" and "Wednesday" and the ouput is "Weekday"
I've tested it out using cases but was unsuccessful with applying that with the values from localStorage
. Is there something wrong with how I've stored my values in the array?
My function for storing and keeping the values checked:
function updateStorage() {
$checkboxes.each(function() {
formValues[this.id] = this.checked;
});
localStorage.setItem("formValues", JSON.stringify(formValues));
}
$checkboxes.on("change", function() {
updateStorage();
});
// On page load
$.each(formValues, function(key, value) {
$("#" + key).prop('checked', value);
});
Here's the issue. Once written to Localstorage, you need to remove the item in order to re-write it
//checkbox
//function for persistent checkbox
var formValues = JSON.parse(localStorage.getItem('formValues')) || {};
var $checkboxes = $("#checkbox-wrapper :checkbox");
function updateStorage(){
$checkboxes.each(function() {
formValues[this.id] = this.checked;
});
localStorage.removeItem('formValues');
localStorage.setItem("formValues", JSON.stringify(formValues));
}
$checkboxes.on("change", function(){
updateStorage();
});
// On page load
$.each(formValues, function(key, value) {
$("#output").html($("#output").html() + key + ": " + value + "<br/>")
});
I updated your code in codepen with above and it works.
Here is a function that will check your days object and return an object with 2 boolean properties ( isWeekDay
and isWeekendDay
):
function checkweekday(days) {
console.log('days', days);
var weekDays = ['monday', 'tuesday', 'wednesday', 'thursday', 'friday'];
var weekendDays = ['saturday', 'sunday'];
var isWeekDay = false;
var isWeekendDay = false;
for (var day in days) {
if (days[day]) {
if (day) {
if (weekDays.indexOf(day) > -1) {
isWeekDay = true;
}
if (weekendDays.indexOf(day) > -1) {
isWeekendDay = true;
}
}
}
}
return {
isWeekDay: isWeekDay,
isWeekendDay: isWeekendDay
}
}
After retrieving values from localStorage, call the function with the object.
var formValues = JSON.parse(localStorage.getItem('formValues')) || {};
var check = checkweekday(formValues);
console.log(check);
Here is an updated plunkr .
I hope you mean something like this
//checkbox
//function for persistent checkbox
var formValues = JSON.parse(localStorage.getItem('formValues')) || {};
var $checkboxes = $("#checkbox-wrapper :checkbox");
function outputResult(isWeekday,isWeekend){
var output = ""
if( isWeekday && isWeekend ) output = "Both";
else if( isWeekday ) output = "Weekday";
else if( isWeekend ) output = "Weekend";
document.getElementById("output").innerHTML = output;
}
function checkDay(){
var isWeekday = false;
var isWeekend = false;
$checkboxes.each(function(){
if( this.checked ){
if( this.id == "saturday" || this.id == "sunday" ) isWeekend = true;
else isWeekday = true;
}
});
outputResult(isWeekday,isWeekend);
}
function updateStorage(){
$checkboxes.each(function(){
formValues[this.id] = this.checked;
});
localStorage.setItem("formValues", JSON.stringify(formValues));
checkDay();
}
$checkboxes.on("change", function(){
updateStorage();
});
// On page load
$.each(formValues, function(key, value) {
$("#" + key).prop('checked', value);
});
