I was trying to use the same function of fontSize() in mobile view to make it responsive but I don't know to do it. This is what I'm using in window view
document.getElementById('hakdog').onload = function () {func()};
function func() {
var str = document.getElementById("voter").innerHTML;
var a = str.length;
if(a >= 40) {
voter.style.fontSize = "18px";
} else if(a >=30) {
voter.style.fontSize = "22px";
} else {
voter.style.fontSize = "27px";
}
}
Is there any same function for mobile view? I only know some function but I know its not responsive
$(document).ready(function(){
if($(window).width() < 480) {
$('h1').css('font-size','10px');
$('h2').css('font-size','8px');
$('h3').css('font-size','6px');
$('h4').css('font-size','4px');
}
});
EDIT
I was trying to make it responsive using java just like on the first code I given, normal .css is not gonna work since its only going to give for h1, h2, h3, etc. I was pointing out that I wanted to make the responsive if the full name reached 40 letters then the fontSize would be 18px same with other functions given
EDIT 5:30pm MARCH 29
This is what I tried so far but didn't work as what I expected.
document.getElementById('hakdog').onload = function () {func()};
function func() {
$(document).ready(function() {
function resizes() {
if($(window).width() < 480) {
var str = document.getElementById("voter").innerHTML;
var a = str.length;
if(a >= 40) {
voter.style.fontSize = "9px";
} else if(a >=30) {
voter.style.fontSize = "10px";
} else {
voter.style.fontSize = "15px";
}
}
}
resizes();
$(window).resize(resizes);
})
}
Edit: Made changes to include the font size based on the length of the content.
This should work. You can check this out on the full page in the below code snippet.
$(document).ready(function() {
function resizeMe() {
if ($(window).width() < 480) {
if ($("#name").text().length < 5) {
$('h1').css('font-size', '46px');
} else {
$('h1').css('font-size', '10px');
}
$('h2').css('font-size', '8px');
$('h3').css('font-size', '6px');
$('h4').css('font-size', '4px');
} else {
$('h1').css('font-size', '20px');
$('h2').css('font-size', '18px');
$('h3').css('font-size', '16px');
$('h4').css('font-size', '14px');
}
}
resizeMe();
$(window).resize(resizeMe);
});

<h4>okkkkkk</h4>
Do you try to change 'px' to 'rem', 'rem' resize in relation to the size of the screen.
This is what i meant for auto sizing for every device
var wid = $(window).width();
if(wid < 320) {
var str = document.getElementById("voter").innerHTML
var a = str.length;
if(a >= 40) {
voter.style.fontSize = "9px";
} else if(a >= 25) {
voter.style.fontSize = "11px";
} else {
voter.style.fontSize = "15px";
}
}
Thanks for everyone commented out!

My code snippet's purpose is to reveal an animation while the scrollY is on 0 if the scrollY is above 0 it will reveal other animations, however, the code only works once.
function reveal() {
var reveals = document.querySelectorAll(".navbar");
var i = 0;
for ( i; i < reveals.length; i++) {
if (window.scrollY > 0) {
reveals[i].classList.add("active");
} else if (window.scrollY == 0) {
reveals[i].classList.add("nactive");
} else {
}
}
}
window.addEventListener("scroll", reveal);
reveal();
the function needs to be looped but I don't know how.
Help me please to understand why not working that part of code.
I'm trying to style a block depending on a variable, but that part doesn't work.
var starsrating = 3;
function markstars() {
if (jQuery(starsrating).val() >= 1) {
jQuery("div.rating-star1").addClass("rating-star-active");
console.log("1");
}
if (jQuery(starsrating).val() >= 2) {
jQuery("div.rating-star1, div.rating-star2").addClass("rating-star-active");
console.log("2");
}
if (jQuery(starsrating).val() >= 3) {
jQuery("div.rating-star1, div.rating-star2, div.rating-star3").addClass("rating-star-active");
console.log("3");
}
if (jQuery(starsrating).val() >= 4) {
jQuery("div.rating-star1, div.rating-star2, div.rating-star3, div.rating-star4").addClass("rating-star-active");
console.log("4");
}
if (jQuery(starsrating).val() >= 5) {
jQuery("div.rating-star1, div.rating-star2, div.rating-star3, div.rating-star4, div.rating-star5").addClass("rating-star-active");
console.log("5");
}
console.log("end of func");
}
markstars();
starsrating is a plain number; you can't call jQuery on it.
A further simplification is to loop over all numbers 1..5 and set the states of the divs programmatically:
function markstars(starsrating) {
for (var i = 1; i <= 5; i++) {
jQuery("div.rating-star" + i).toggleClass("rating-star-active", starsrating >= i);
}
}
markstars(3);
My menu is sliding down into the page as I want but it does not go up to a "0px" i marginTop when I click the image again. The image has a onclick="meny()" event.
var menu;
var x = 0;
function meny() {
menu = document.getElementById('menu-slider');
if(x = 1) {
menu.style.marginTop = "0px";
x = 0;
} else if(x = 0) {
menu.style.marginTop = "-300px";
x = 1;
}
};
You might want to get rid of the quotes here: x='0' and try x=1 instead of x=x+1 same goes for the else if
It should be
if(x == 1) {
...
} else if (x == 0) {
...
}
rather than
if (x = 1) {
...
} else if (x = 0) {
...
}
I have a javascript function that I need modified for certain screen sizes, though I've tried "if (screen.width <= 960) {... " and "if (window.width <= 960) {..." , only the part after "else" get's executed, like it's not even looking at the screen width I'm placing in the parenthesis.
Here is my function ( I know it's poorly written, but I'm new to javascript):
$(document).ready(function(){
var numberofscroll = 0;
var lastScrollTop = 0;
$("#home").scroll(function(){
var st = $(this).scrollTop();
(st > lastScrollTop) ? numberofscroll++ : numberofscroll--;
console.log(numberofscroll);
console.log(lastScrollTop);
console.log(st);
if (numberofscroll<2){
change_background2(numberofscroll);
}
else if (numberofscroll<3){
change_background3(numberofscroll);
}
else if (numberofscroll<4){
change_background4(numberofscroll);
}
lastScrollTop = st;
});
function change_background2(numberofscroll){
var i;
for (i = 2) {
$("#home").css("background-position","0 -652px");
}
}
function change_background3(numberofscroll){
var i;
for (i = 3) {
$("#home").css("background-position","0 -1326px");
}
}
function change_background4(numberofscroll){
var i;
for (i = 4) {
$("#home").css("background-position","0 -1978px");
}
}
)};
Corrections:
Changed all the for to ifs.
Corrected the parentheses.
Assigned a temp variable to ternary operation.
Changed all the i to numberofscroll
I believe the corrected JavaScript is:
$(document).ready(function () {
var numberofscroll = 0;
var lastScrollTop = 0;
$("#home").scroll(function () {
var st = $(this).scrollTop();
n = (st > lastScrollTop) ? numberofscroll++ : numberofscroll--;
console.log(numberofscroll);
console.log(lastScrollTop);
console.log(st);
if (numberofscroll < 2) {
change_background2(numberofscroll);
} else if (numberofscroll < 3) {
change_background3(numberofscroll);
} else if (numberofscroll < 4) {
change_background4(numberofscroll);
}
lastScrollTop = st;
});
function change_background2(numberofscroll) {
if (numberofscroll == 2) {
$("#home").css("background-position","0 -652px");
}
}
function change_background3(numberofscroll) {
if (numberofscroll == 3) {
$("#home").css("background-position","0 -1326px");
}
}
function change_background4(numberofscroll) {
if (numberofscroll == 4) {
$("#home").css("background-position","0 -1978px");
}
}
});
I think you want to use the innerWidth property of window. (https://developer.mozilla.org/en/docs/Web/API/window/innerWidth).
I'm writing the same code three times for the different pages of my WordPress site. I feel that it could be written more elegantly but unfortunately I'm not at the skill level yet to achieve this. Is there any way to combine all of this into something more concise? It would also probably help me learn more about what can and can't be done with JavaScript.
if (jQuery(document.body).hasClass("home")) {
jQuery(window).scroll(function () {
var threshold = 654;
if (jQuery(window).scrollTop() >= 654)
jQuery('#sidebar').addClass('fixed');
else
jQuery('#sidebar').removeClass('fixed');
});
} else if (jQuery(document.body).hasClass("single") || jQuery(document.body).hasClass("page")) {
jQuery(window).scroll(function () {
var threshold = 20;
if (jQuery(window).scrollTop() >= 20)
jQuery('#sidebar').addClass('fixed');
else
jQuery('#sidebar').removeClass('fixed');
});
} else {
jQuery(window).scroll(function () {
var threshold = 236;
if (jQuery(window).scrollTop() >= 236)
jQuery('#sidebar').addClass('fixed');
else
jQuery('#sidebar').removeClass('fixed');
});
}
var threshold = 236;
if (jQuery(document.body).hasClass("home")) {
threshold = 654;
} else if (jQuery(document.body).hasClass("single") || jQuery(document.body).hasClass("page")) {
threshold = 20;
}
var scrolled = false;
jQuery(window).scroll(function () {
if (!scrolled && jQuery(window).scrollTop() >= threshold){
jQuery('#sidebar').addClass('fixed');
scrolled = true;
} else if (scrolled && jQuery(window).scrollTop() < threshold) {
jQuery('#sidebar').removeClass('fixed');
scrolled = false;
}
});
UPDATE: I was created a simple demo to show how to implement sidebar scrolls within his parent.
Demo on CodePen
Damn.. I got beat. Well, I'm still posting this anyway.
var scrollTopFn = function(amount){
$(window).scroll(function(){
// this is a ternary statement, basically a shorthand for writing if else statements
$(window).scrollTop() >= amount
? $('#sidebar').addClass('fixed')
: $('#sidebar').removeClass('fixed');
});
}
if ($(document.body).hasClass('home')) {
scrollTopFn(654);
} else if ($(document.body).hasClass('single')){
scrollTopFn(20);
} else {
scrollTopFn(236);
}
Could be:
var threshold = 236;
switch (jQuery(document.body).attr("class")) {
case "home":
threshold = 654
break;
case "single":
case "page":
threshold = 20
break;
}
$(window).scroll(function () {
if (jQuery(window).scrollTop() >= threshold )
jQuery('#sidebar').addClass('fixed');
else
jQuery('#sidebar').removeClass('fixed');
});
Your code could be simplified to:
var $body = jQuery(document.body),
threshold = $body.hasClass("home") ? 654
: $body.hasClass("single") || $body.hasClass("page") ? 20
: 236;
jQuery(window).on('scroll', function() {
jQuery('#sidebar').toggleClass('fixed', state);
});
But this one should have better performance:
var $body = jQuery(document.body),
state = false,
threshold = $body.hasClass("home") ? 654
: $body.hasClass("single") || $body.hasClass("page") ? 20
: 236;
jQuery(window).on('scroll', function() {
if(state != (state = jQuery(window).scrollTop() >= threshold))
jQuery('#sidebar').toggleClass('fixed', state);
});
