I have a jquery function that when a li is clicked, the li expands. That part is working fine. Now, I want, when the li is clicked it toggles a background color. But it works, however when i have to click on the li item again to untoggle the background color. Can someone assist me in the right direction on how to achieve this.
$(function() {
$('.a').click(function() {
var name = $(this).attr("name");
var content = $('.content[name=' + name + ']');
$('.content').not(content).hide('fast');
$('.selected').css('background', 'yellow');
content.slideToggle('fast');
});
$("li").click(function() {
$(this).toggleClass("highlight");
});
});
On every click set your <li>-s to default color and highlight the current:
$("li").click(function() {
$("li").removeClass("highlight");
$(this).addClass("highlight");
});
...
UPDATE
http://jsfiddle.net/NXVhE/4/
$(function() {
$('.a').click(function() {
$(this).removeClass("highlight");
var name = $(this).attr("name");
var content = $('.content[name=' + name + ']');
$('.content').not(content).hide();
content.toggle();
});
$("a").click(function () {
$("a").removeClass("highlight");
if ( $(".content").is(":visible") ) {
$(this).addClass("highlight");
}
});
});
Assuming the <li>s are all siblings, it would be slightly more efficient to do something like this, and would allow for more than one list on the same page to function independently of one another (again, assuming that is the desired functionality)
$('li').click(function() {
$('this').addClass('highlight').siblings().removeClass('highlight').
});

I have the following example:
https://codepen.io/baidoc/pen/LYVvOZq
jQuery(function ($) {
$(".box").click(function() {
$(".box").removeClass("active");
$(this).addClass("active");
$(".boxContent").removeClass("show-content");
var target = $(this).attr("target");
$(".boxContent_" + target).addClass("show-content");
});
});
2 Boxes, by default deactivated (hidden), and only once clicked, the content will be shown.
What I'm trying to do: when I click again on the box, it should hide the box (display:none)
I've tried with toggle function, but somehow it doesn't seem to work. What alternative do I have?
What about this?
jQuery(function ($) {
$(".box").click(function() {
var currentActive = $(this).hasClass("active");
$(".boxContent").removeClass("show-content");
$(".box").removeClass("active");
if (!currentActive){
$(this).addClass("active");
var target = $(this).attr("target");
$(".boxContent_" + target).addClass("show-content");
}
});
});
Try this below :
jQuery(function ($) {
$(".box").click(function() {
$(".box").removeClass("active");
$(this).addClass("active");
if($(".boxContent").hasClass("show-content")){
$(".boxContent").removeClass("show-content");
}else{
var target = $(this).attr("target");
$(".boxContent_" + target).addClass("show-content");
};
});
});
adding active class to parent list when link is clicked/active , am trying to inject that using JavaScript as follow:
$(document).ready(
function()
{
//injecting active status to the navigation bar lists
var element = document.getElementById("navbar-ul");
var links = element.getElementsByTagName("a");
for(var i = 0; i < links.length ; i++) {
links[i].onclick(function () {
links[i].parent().addClass('active');
});
}
}
);
but am getting the following error:
TypeError: links[i].onclick is not a function
how I supposed to achieve that?
A more verbose JQuery way to approach this
$('#navbar-ul a').each(function() {
$(this).on('click', function() {
$(this).parent().addClass('active');
});
});
This is very simply with jQuery:
$("#navbar-ul a").click(function(){
$(this).parent().addClass("active");
});
EXAMPLE 1
I'm guessing you're trying to add an active state to the link thats being clicked on and remove the others? If so you can use .siblings() to find the other links and remove their class:
$("#navbar-ul a").click(function(){
$(this).closest("li").addClass("active").siblings("li").removeClass("active");
});
EXAMPLE 2
You would be better of with adding a class to the tags who needs an eventListener. (with jquery)
$(document).ready(function() {
$("#navbar-ul a").on("click", function() {
var active = document.querySelector('#navbar-ul .active');
if(active){
$("#navbar-ul a").removeClass('active');
}
$(this).addClass("active");
});
);
I have a Select option where if I select any option related div Shows up. Upto this it's fine. But I am wanting to make something like if I select the option it will display the related div but option it self will be removed.
FIDDLE
Is this possible ? Any help will be appreciated.
JS
$(document).ready(function() {
$('#contact-location').change(function(){
var location = $(this).val(),
div = $('#' + location);
$('div').hide();
div.show();
});
});
Fixed my answer to reflect the update in the question:
$(document).ready(function() {
$('#contact-location').change(function(){
var location = $(this).val(),
div = $('#' + location);
var selIndex = $("#contact-location").prop('selectedIndex');
$("#contact-location").prop(selIndex).remove();
$('div').hide();
div.show();
});
});
http://jsfiddle.net/uwt73sj3/
var selIndex = $("#contact-location").prop('selectedIndex'); here we set the select element index to a variable we can work with later.
$("#contact-location").prop(selIndex).remove(); removed the index value from the select drop down.
You could try something like:
$(document).ready(function() {
$('#contact-location').change(function(){
$('#contact-location option').show(); //clean alls
$('option:selected',this).hide(); // hide selected
var location = $(this).val(),
div = $('#' + location);
$('div').hide();
div.show();
});
})
LIVE DEMO
Why not make things more generic at the same time?
$(function () {
$('#contact-location').change(function () {
var $this = $(this);
// show only correct location
$('div').hide(); // maybe use a class rather than hiding every <div>
$('#' + $this.val()).show();
// show only alternate options
$this.find('option').show();
$this.find('option:selected').hide();
});
});
one solution is to use click on the children of select (i.e. the options) and then hide this (which is the option). Then the value of the select still has the value of the selected option and you have to reset it manually (I used the content of the first child via the css :first-child selector but you could use anything else, too).
$(document).ready(function(e) {
$('#contact-location').children().click(function(){
var $select = $(this).parent();
var $clicked = $(this);
var location = $clicked.val(); //is the same like $select.val()
var $div = $('#' + location);
$clicked.hide();
$select.val($select.children(":first-child"));
$div.show();
});
});
I used $ before the names of some variables to indicate that these variables store jQuery objects.
You can get the selected option like this:
$("option:selected", this);
From there you can hide or remove it:
$("option:selected", this).hide();
$("option:selected", this).remove();
I am using the title attribute in all my links but I don't want to be visible on mouse hover, but still visible in the code for screen readers.
var links = document.getElementsByTagName('a');
for (var i = 0; i < links.length; i++) {
if (links[i].className == 'suppress') {
links[i]._title = links[i].title;
links[i].onmouseover = function() {
this.title = '';
}
links[i].onmouseout = function() {
this.title = this._title;
}
Using jQuery, you can hide the title attr on hover, and replace it on mouseout:
$(function(){
$('a').hover(function(e){
$(this).attr('data-title', $(this).attr('title'));
$(this).removeAttr('title');
},
function(e){
$(this).attr('title', $(this).attr('data-title'));
});
});
Like in this fiddle.
Since you are using jQuery, you can do it in a simple way:
$(document).ready(function(){
$("a").removeAttr("title");
});
Or, setting it to empty value:
$(document).ready(function(){
$("a").attr("title", "");
});
If this is gonna change the way the screen readers read, then, you can just target on hover.
$(document).ready(function(){
$("a").hover(function(){
$(this).attr("rel", $(this).attr("title"));
$(this).removeAttr("title");
}, function(){
$(this).attr("title", $(this).attr("rel"));
$(this).removeAttr("rel");
});
});
I was trying to create a bubble tool-tip in CSS but the browser tool-tip would always appear and mess things up. So, like you, I needed to disable the default tool-tip.
I used a bit of JQuery to remove the "Title" tag but only on mouse hover. As soon as the mouse is out, the "Title" tag is restored.
Following is a DIV with some "Title" content:
<div class="tooltip-class" title="This is some information for our tooltip.">
This is a test
</div>
Now you can run the following JQuery to hide the Title tag on mouse hover:
$(document).ready(function(){
$(".tooltip-class").hover(function(){
$(this).attr("tooltip-data", $(this).attr("title"));
$(this).removeAttr("title");
}, function(){
$(this).attr("title", $(this).attr("tooltip-data"));
$(this).removeAttr("tooltip-data");
});
});
Following is a link to the full example:
http://jsfiddle.net/eliasb/emG6E/54/
$(".element").hover(function(){
// Get the current title
var title = $(this).attr("title");
// Store it in a temporary attribute
$(this).attr("tmp_title", title);
// Set the title to nothing so we don't see the tooltips
$(this).attr("title","");
});
$(".element").click(function(){// Fired when we leave the element
// Retrieve the title from the temporary attribute
var title = $(this).attr("tmp_title");
// Return the title to what it was
$(this).attr("title", title);
});
i am using jquery for set background color to the table data and its working fine but i need when user again click the td the color should be deselect. its my script for add color.
java script:
jQuery('td').click(function () { $(this).addClass('active'); });
my css class:
.active{background-color:red;}
when user again click the td the class should remove. How to achieve this.
jQuery('td').click(function () { $(this).toggleClass('active'); });
toggleClass adds if it doesn't exist or removes if it does exist.
You can use
$(this).removeClass('active');
although you would need to do a check to see if it is already active, which would make your code look like this:
jQuery('td').click(function () {
if($(this).hasClass('active') {
$(this).removeClass('active');
} else {
$(this).addClass('active');
}
});
EDIT:
#Justice is more correct:
jQuery('td').click(function () { $(this).toggleClass('active'); });
