On the desktop sizes, my navbar brand includes only one larger image. But on the mobile sizes I want that larger image to be replaced with two smaller images. For that, I have used jQuery and when I check it on the mobile it looks just how I wanted to. But the problem is that as I change my browser's size the image is not being replaced in real time. Is there a way I could achieve this?
$(document).ready(function() {
if ($(window).width() < 575.98) {
$('.navbar-brand').children().remove();
$('.navbar-brand').append('<img src="assets/images/Llogo AIP.png"><img src="assets/images/CoA RKS.png">');
}
});
<a class="navbar-brand" href="index.html"><img src="assets/images/logo.png"></a>
To get the code to be executed on resizing the window you should use .resize():
The resize event is sent to the window element when the size of the browser window changes.
$(window).resize(function() {....
Demo:
$(document).ready(function() {
if ($(window).width() < 575.98) {
$('.navbar-brand').children().remove();
$('.navbar-brand').append('<img src="https://homepages.cae.wisc.edu/~ece533/images/pool.png"><img src="https://homepages.cae.wisc.edu/~ece533/images/fruits.png">');
}
$(window).resize(function() {
if ($(window).width() < 575.98) {
$('.navbar-brand').children().remove();
$('.navbar-brand').append('<img src="https://homepages.cae.wisc.edu/~ece533/images/pool.png"/><img src="https://homepages.cae.wisc.edu/~ece533/images/fruits.png"/>');
}
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<a class="navbar-brand" href="index.html"><img src="assets/images/logo.png"></a>
This behavior is because the image is only replaced at document ready, aka when the document has finished loading.
If you want to change the images on window resize you need the resize event handler, as Mamun pointed out.
In that case you probably also want to switch back to the original image when you make the screen larger. I would make a separate function to handle setting the correct images and call it on window resize and on document ready. For example:
$(document).ready(function() {
setNavImages();)
});
$(window).resize(function(){
setNavImages()
});
function setNavImages(){
if ($(window).width() < 575.98) {
$('.navbar-brand').children().remove();
$('.navbar-brand').append('<img src="assets/images/Llogo AIP.png"><img src="assets/images/CoA RKS.png">');
}else{
$('.navbar-brand').children().remove();
$('.navbar-brand').append('<img src="[your original image here]">');
}
}
Like #Mamun said and call it on document ready
or better use bootstrap hidden-xs visible-md classes
$(document).ready(function() {
$(window).resize(function() {
if ($(window).width() < 575.98) {
$('.navbar-brand').children().remove();
$('.navbar-brand').append('<img src="assets/images/Llogo AIP.png"><img src="assets/images/CoA RKS.png">');
}
});
$(window).resize(); // call it here after define it
});
<a class="navbar-brand" href="index.html"><img src="assets/images/logo.png"></a>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
With this code the navbar will change like you want, on every resize, for example.
$(document).ready(function() {
navbarBrandContent = $('.navbar-brand').html();
changeNavbarBrand();
});
$(window).resize(function() {
changeNavbarBrand();
});
function changeNavbarBrand() {
if ($(window).width() < 575.98) {
$('.navbar-brand').children().remove();
$('.navbar-brand').append('<img src="assets/images/Llogo AIP.png"><img src="assets/images/CoA RKS.png">');
} else {
$('.navbar-brand').html(navbarBrandContent);
}
}

I need a menu to open when I am hovering over an li when above 768px window width, and it to open when I click the same li when below 768px window width. I keep having problems where the click, or hover, carries over between the two screen sizes (0-768px and 769 and up).
function colorChangeTest(width){
if (width <= 767) {
$('li').click(function() {
$(this).toggleClass('colorChange');
});
} else {
$('li').hover(function() {
$(this).toggleClass('colorChange');
});
}
}
$(function () {
var onLoadWidth = $(window).width();
colorChangeTest(onLoadWidth);
$(window).resize(function () {
var resizeWidth = $(window).width();
colorChangeTest(resizeWidth);
});
})

What is the best way to do responsive jQuery that tell something it can be clicked, or hovered, depending on screen size, and determine this on page load and window resize?
FYI it is better to attach the same event listeners once in code to the same elements. In your case each time when window is resizing new event listeners (hover or click) are attached again and again.
Use unbind to aviod it. For example:
function colorChangeTest(width){
var $li= $('li');
$li.unbind();
if (width <= 767) {
$li.click(function() {
$(this).toggleClass('colorChange');
});
} else {
$li.hover(function() {
$(this).toggleClass('colorChange');
});
}
}
I have a link that in normal when I click on it, it gives me a alert() (using jquery).
HTML:
<a class="link" href="www.example.com">link</a>
JS:
$(".link").click(function() {
alert('clicked');
return false;
});
CSS:
#media (min-width: 980px)
{
// In this width, when user click on that link,
// I want to open www.eample.com
}
Now my question is this: How do i determine wether the client's width is less than or greater than 980 pixels?
you can use $(window).width()
$(".link").click(function() {
if($(window).width() >= 980){
alert('clicked');
return false;
}
});
I'm unsure of what you want to do but if i understand correctly you want some javascript code to run when the client's width is smaller/bigger than a certain amount of pixels.
If that's the case you'd have to check within the click callback function whether the clients screen was larger/smaller than 980px.
$(".link").click(function () {
if (window.innerWidth > 980) {
alert('clicked');
return false;
}
});
You can not deactivate JavaScript using CSS, you'd have to use JavaScript and check the width with $(window).width()
$(".link").click(function() {
if ($(window).width() >= 980) {
alert('clicked');
return false;
}
});
I think match media is pretty sweet also:
var mq = window.matchMedia('#media (min-width: 980px)');
var link = document.querySelector('.link');
link.href = mq.matches ? "http://www.example.com" : "";
EDIT:
Oh, as #Oscar points out: If you're worried about the combined ~16% market share (oct/2015) of IE8/IE9, go with the jquery method detailed in the chosen answer.
I want java script functionality only in mobile device 767px.
This is my code
$('#my-btnn').click(function () {
$('#mobile-login').hide();
$('#user-settings').slideToggle('fast');
});
You can simply check window width in order to determine if function should work or not:
$('#my-btnn').click(function () {
if ($(window).width() < 767) {
$('#mobile-login').hide();
$('#user-settings').slideToggle('fast');
}
});
You can bind your click by checking your resolution. Use onResize and check by screen.width
$(window).resize(function() {
if (screen.width <= 767) {
$('#my-btnn').bind('click', function () {
$('#mobile-login').hide();
$('#user-settings').slideToggle('fast');
});
}
});
And you can check if you were binded early.
Or you can just to add this checking in onReload
I have a menu that is hidden in an accordion when viewing on screens less than 600px.
On screens larger than 600px the menu is visible.
jsfiddle- http://jsfiddle.net/ashatron/zbzqoz2f/
it works ok, but when i resize the window to be greater than 600px, then go back to less than 600px then press view sitemap it loops the animation multiple times.
I think its running the function for every resize event, which is queing up the accordion and then looping it. But I'm not sure how best to order the syntax to get it to work.
Any help would be appreciated!
footernavmenufn = function() {
var current_width = $(window).width();
if (current_width < 600) {
$('.footer-accordion-head').show();
$('.footer-accordion-body').hide();
$('.footer-accordion-head').click(function () {
$(".footer-accordion-body").slideToggle('400');
// console.log('hmmm');
return false;
}).next().hide();
} else {
$('.footer-accordion-head').hide();
$('.footer-accordion-body').show();
}
};
$(document).ready(function () {
footernavmenufn();
});
$(window).resize(function(){
footernavmenufn();
//console.log('OMG-WHY-YOU-NO-WORK');
});
The issue is that everytime window is resized and the condition is met, you're binding a new click event handler, so after a while there'll be multiple event handlers causing chaos. Ideally your code should be something like
$(document).ready(function () {
$('.footer-accordion-head').click(function () {
$(".footer-accordion-body").slideToggle('400');
console.log('hmmm');
return false;
});
$(window).resize(footernavmenufn);
footernavmenufn(); // or $(window).trigger("resize");
});
footernavmenufn = function () {
var current_width = $(window).width();
if (current_width < 600) {
$('.footer-accordion-head').show();
$('.footer-accordion-body').hide();
} else {
$('.footer-accordion-head').hide();
$('.footer-accordion-body').show();
}
};
Updated Fiddle
Why do you have this code? Crazy one. Remove it:
if (current_width < 600) {
$('.footer-accordion-head').show();
$('.footer-accordion-body').hide();
$('.footer-accordion-head').click(function () {
$(".footer-accordion-body").slideToggle('400');
return false;
}
move the click declaration into the $(document).ready function.
at the moment everytime you resize the page that click function is being added again - so the repeat is once per page resize.

I have this landing page that has a left navigation when it the screen with 1024 or larger but when the screen goes below 1024 the left navigation appears on the top of the main content of the page and the "Walmart Leverage becomes a button with on click event for the rest of the navigation to come down. the code works until I put the if statement to detect what size the screen is. Probably missing something to the code. Below is the link for the page.
http://dl.dropboxusercontent.com/u/2399619/walmartmilitary/talentbrew-LeverageHome.html
This is the code for the jQuery
$(window).resize(function() {
if( $(this).width() < 1024) {
var $showSubBtn = $("#sn-walmartleverage");
$showSubBtn.click(function(){
if($(this).hasClass("active")) {
$(this).parent().next().hide();
$(this).removeClass("active");
} else {
$(this).addClass("active");
$(this).parent().next().show();
}
return false;
});
}
});
Any help would be much appreciated.
Thanks
You can't put the click event handler inside the window resize event handler, you should just check the window size when the click happens
$("#sn-walmartleverage").on('click', function(e){
e.preventDefault();
if ($(window).width() > 1024) {
$(this).toggleClass('active').parent().next().toggle();
}
});
