How to add click event JS for interactive map of the mall?

I'm trying to make an interactive mall map. JS code works correctly on hover. But I need to add on click as well. That is, to work the same way when hovering and clicking on the menu.
Here is the JS code:
//map
var id = 0;
$(' .scheme-about__item .menu__link').mouseover(function(e) {
id = $(this).attr('data-id');
if(isMobile()) {
$('.area-m-' + id).addClass('hover');
} else {
$('.area-' + id).addClass('hover');
}
console.log($('.area-' + id));
})
.mouseout(function(e) {
if(isMobile()) {
$('.area-m-' + id).removeClass('hover');
} else {
$('.area-' + id).removeClass('hover');
}
});
function isMobile() {
var res = navigator.userAgent.match(/Android|BlackBerry|iPhone|iPad|iPod|Opera Mini|IEMobile|Windows Phone|PlayBook|BB10|Nokia/i);
if (res != null)
return true;
else
return false;
}

You can try this one.
//map
let id = 0;
let menuLink = document.querySelector('.scheme-about__item .menu__link');
menuLink.addEventListener('click',mapFunction);
menuLink.addEventListener('mouseover',mapFunction);
menuLink.addEventListener('mouseout',mapFunction);
function mapFunction(e){
id = e.target.getAttribute('data-id');
if(isMobile()) {
document.querySelector('.area-m-' + id).classList.add('hover');
} else {
document.querySelector('.area-' + id).classList.add('hover');
}
console.log(document.querySelector('.area-' + id)
}
function isMobile() {
var res = navigator.userAgent.match(/Android|BlackBerry|iPhone|iPad|iPod|Opera Mini|IEMobile|Windows Phone|PlayBook|BB10|Nokia/i);
if (res != null)
return true;
else
return false;
}

Why does this my recursive function work after dividing a tag.class selector without dividing the matching tag.class new one?

I've been trying to do some html and css but I'm really bad at this so far. I was using a function that would check if two selectors match. A friend of mine came up with this code but neither of us fully understands how the return of the "tag.class" case works. My question is, if it doesn't divide the newSelector, how can it succesfully check the tag and class?
var matchFunctionMaker = function(selector) {
var selectorType = selectorTypeMatcher(selector);
var matchFunction;
if (selectorType === "id") {
matchFunction = nuevoSelector => '#' + nuevoSelector.id === selector;
} else if (selectorType === "class") {
matchFunction = nuevoSelector => {
var lista = nuevoSelector.classList;
for (let x of lista) {
if (selector === '.' + x) return true;
}
return false;
}
} else if (selectorType === "tag.class") {
matchFunction = nuevoSelector => {
var [tag, clase] = selector.split('.');
return matchFunctionMaker(tag) (nuevoSelector) && matchFunctionMaker(`.${clase}`) (nuevoSelector);
};
} else if (selectorType === "tag") {
matchFunction = nuevoSelector => nuevoSelector.tagName.toLowerCase() === selector.toLowerCase();
}
return matchFunction;
};
Thanks in advance!

Merging two functions into one to simplify the code

I got these two functions, and they work great.
But since I only call global.replaceFields from global.translateAll then I want to get rid of global.replaceFields and put its functionality inside global.translateAll
How would you go about merging global.replaceFields into global.translateAll without losing the current functionality?
Thanks :)
// Translate everything in that field
global.translateAll = (textfield, usersLanguage) => {
for (var property in textfield) {
if (!textfield.hasOwnProperty(property)) {
return false;
} else if (typeof textfield[property] !== "object") {
textfield[property] = global.replaceFields(textfield[property], usersLanguage);
} else {
global.translateAll(textfield[property], usersLanguage);
}
}
}
// Translate everything in that field
global.replaceFields = (textfield, usersLanguage) => {
// Keep running until all fields are replaced
while (textfield.indexOf("{{") != -1) {
// isolate the field
let fromField = textfield.substring((textfield.indexOf("{{") + 2), (textfield.indexOf("}}")));
let toField = ""
// If its a translated text
if (fromField.indexOf("trans") != -1) {
toField = usersLanguage[fromField];
textfield = textfield.replace("{{" + fromField + "}}", toField);
}
}
return (textfield);
}

This should work
global.translateAll = (textfield, usersLanguage) => {
var replaceFields = (textfield, usersLanguage) => {
// Keep running until all fields are replaced
while (textfield.indexOf("{{") != -1) {
// isolate the field
let fromField = textfield.substring((textfield.indexOf("{{") + 2), (textfield.indexOf("}}")));
let toField = ""
// If its a translated text
if (fromField.indexOf("trans") != -1) {
toField = usersLanguage[fromField];
textfield = textfield.replace("{{" + fromField + "}}", toField);
}
}
return (textfield);
}
for (var property in textfield) {
if (!textfield.hasOwnProperty(property)) {
return false;
} else if (typeof textfield[property] !== "object") {
textfield[property] = replaceFields(textfield[property], usersLanguage);
} else {
global.translateAll(textfield[property], usersLanguage);
}
}
}

Access array in if statement

I have JavaScript calculator wherein I have defined two arrays as follows:
var degInc, degArr = [];
var radInc, radArr = [];
var PI = Math.PI;
var radStart = (-91*PI/2), radEnd = (91*PI/2);
for (degInc = -8190; degInc <= 8190; degInc+=180) {
degArr.push(degInc);
}
for (radInc = radStart; radInc <= radEnd; radInc+=PI) {
var radIncFixed = radInc.toFixed(8);
radArr.push(radIncFixed);
}
to be used in conjunction with the tangent function (below) so as to display a value of Undefined in an input (HTML below) should the user attempt to take the tangent of these values (I have included other relavent function as well):
Input -
<INPUT NAME="display" ID="disp" VALUE="0" SIZE="28" MAXLENGTH="25"/>
Functions -
function tan(form) {
form.display.value = trigPrecision(Math.tan(form.display.value));
}
function tanDeg(form) {
form.display.value = trigPrecision(Math.tan(radians(form)));
}
function radians(form) {
return form.display.value * Math.PI / 180;
}
with jQuery -
$("#button-tan").click(function(){
if (checkNum(this.form.display.value)) {
if($("#button-mode").val() === 'DEG'){
tan(this.form); // INSERT OTHER 'if' STATEMENT HERE FOR RAD ARRAY
}
else{
tanDeg(this.form); // INSERT OTHER 'if' STATEMENT HERE FOR DEG ARRAY
}
}
});
I would like to incorporate an array check within the .click function such that if the user input is contained in the array (degArr or radArr depending on the mode), the calculator returns Undefined. Now, I know how to display Undefined in the input display ($('#disp').val('Undefined')), but I cannot figure out how to configure an if statement that checks the relevant array. Is there a way to do so within the #button-tan function where I have commented?

Loop through the arrays on click and set a variable if you find a matched value.
You can do something like this:
$("#button-tan").click(function(e) {
e.preventDefault();
var userInput = $('#disp').val();
var buttonMode = $('#button-mode').val();
var displayVal = '';
if (buttonMode === 'DEG') {
var radFound = false;
radArr.forEach(function(item) { // changed from degArr
if (item === userInput) {
radFound = true;
}
if (radFound) {
displayVal = 'undefined';
} else {
tan(this.form);
}
});
} else {
var degFound = false;
degArr.forEach(function(item) {
if (item === userInput) {
degFound = true;
}
if (degFound) {
displayVal = 'undefined';
} else {
tanDeg(this.form);
}
});
}
});

You could create a simple object of a Calculator class, which keeps a reference to these arrays, and use like this. I changed some methods to receive the input as parameter rather than form.
$(function () {
function Calculator()
{
var degInc;
this.degArr = [];
var radInc;
this.radArr = [];
var PI = Math.PI;
var radStart = (-91*PI/2);
var radEnd = (91*PI/2);
for (degInc = -8190; degInc <= 8190; degInc+=180) {
this.degArr.push(degInc);
}
for (radInc = radStart; radInc <= radEnd; radInc+=PI) {
var radIncFixed = radInc.toFixed(8);
this.radArr.push(radIncFixed);
}
}
var calc = new Calculator();
function tan(input) {
alert("tan called");
var value = Math.tan(input.value);
alert("tan called. value: " + value);
input.value = value;
}
function tanDeg(input) {
alert("tanDeg called");
var value = Math.tan(radians(input));
alert("tanDeg called. value: " + value);
input.value = value;
}
function radians(input) {
alert("radians called");
var value = input.value * Math.PI / 180;
alert("radians called. value: " + value);
return value;
}
$("#button-tan").click(function(){
alert (calc.degArr);
alert (calc.radArr);
var displayInput = $("#disp");
alert("user input: " + displayInput.val());
if (!isNaN(displayInput.val()))
{
if($("#button-mode").val() === 'DEG')
{
if (calc.radArr.indexOf(displayInput.val()) > -1)
{
alert("user input is in radArr");
}
else
{
alert("user input IS NOT in radArr");
tan(displayInput);
}
}
else
{
if (calc.degArr.indexOf(displayInput.val()) > -1)
{
alert("user input is in degArr");
}
else {
alert("user input IS NOT in degArr");
tan(displayInput);
}
}
}
else
alert("Not a number in input");
});
});
If you wanna do some tests, I created a JSFiddle demo here. Type -8190 in the first input, then click the button. It's gonna be inside the array. Then try typing "DEG" in the second input and clicking again, you'll notice code will check against another array (due to IFs). I couldn't make your auxiliar functions to calculate a value, but I think this helps you with your initial problem.

indexOf should work...
$("#button-tan").click(function(){
if (checkNum(this.form.display.value)) {
if($("#button-mode").val() === 'DEG'){
if (radArr.indexOf(Number(this.form)) > -1) {
$('#disp').val('Undefined');
} else {
tan(this.form);
}
}
else{
if (degArr.indexOf(Number(this.form)) > -1) {
$('#disp').val('Undefined');
} else {
tanDeg(this.form);
}
}
}
});

jQuery works on the second event, but no the first one

I couldn't find out why my code doesn't work correctly
I have this function:
function checkIt(input_name, input_value){
if (input_name === 'firstname') {
y = regs[0];
} else if (input_name === 'lastname') {
y = regs[1];
} else if (input_name === 'phone') {
y = regs[2];
} else if (input_name === 'mail') {
y = regs[3];
} else {
y = regs[4];
}
z = input_value.match(y1);
if (z !== null) {
rez = true;
} else {
rez = false;
}
return rez;
}
and then im doing this:
$(document).on("blur", "input[name=firstname]", function(){
p = $(this).prop("name");
q = $(this).val();
r = checkIt(p, q);
if (r) {
// something
} else {
// something
}
});
and my problem is that my code doesn't work on first blur. it's starting executing on second blur and does everything perfecty... :/

try using on("blur", "input", function) without parameter name, because do u have the var p with prop of this input.
$(document).on("blur", "input", function(){
p = $(this).prop("name");
q = $(this).val();
r = checkIt(p, q);
if (r) {
// something
} else {
// something
}
});
