how to change clickable item when i click them in JqueryMobile? - css

I am developing a task in using phonegap and jquerymobile.
How should i do to change the color of a clickable item when i click on them?
I have written the code below:
$(".testbutton").click(function(){
$(".testbutton").css("background-color","yellow");
});
But the background color will only change yellow after i release my mouse on it. I wan it to change to yellow whenever my mouse is clicked on tat item, and recover to its original background color when i release the mouse.
Can anyone please help?

Is this what you're trying to accomplish?
Live Example:

CSS:
.task-bg-color {
background-color: yellow;
}
JS:
$('#clickAndHold').mousedown(function() {
$(this).children().addClass('task-bg-color');
$('ul#tasks').listview('refresh');
});
$('#clickAndHold').mouseup(function() {
$(this).children().removeClass('task-bg-color');
$('ul#tasks').listview('refresh');
});
$('#clickAndStick').click(function() {
$(this).children().addClass('task-bg-color');
$('ul#tasks').listview('refresh');
});
$('#clickAndToggle').click(function() {
if ($(this).children().hasClass('task-bg-color')) {
$(this).children().removeClass('task-bg-color');
} else {
$(this).children().addClass('task-bg-color');
}
$('ul#tasks').listview('refresh');
});

How can I active status when I click on nav menu?

I have a menu including the following li
<div class="menu">
<ul>
<li>Home</li>
<li>News</li>
<li><a href="abc.jsp">ABC</li>
</ul>
</div>
In this code, home page is actived. But want to enable active status when I click on my News page. How Can I do? Thanks for watching.
Please add Js like:
jQuery(document).ready(function () {
jQuery('.menu li a').click(function () {
//removing the previous selected menu state
jQuery('.menu li').find('a.active').removeClass('active');
//adding the state for this parent menu
jQuery(this).addClass('active');
});
});
a.active {
color: red;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="menu">
<ul>
<li>Home</li>
<li>News</li>
<li><a href="abc.jsp">ABC</li>
</ul>
</div>
You can use jQuery to do so, use the script below:
$(document).ready(function () {
$('.menu ul li a').click(function () {
// This will remove active class from other links
$('.menu ul li').find('a.active').removeClass('active');
// This will add active class to the link clicked
$(this).addClass('active');
});
});
Here is code using pure javascript
화이팅!!
function change(elem){
var list = document.querySelectorAll(".menu ul li a");
for (var i = 0; i < list.length; ++i) {
list[i].classList.remove('active');
}
elem.classList.add('active');
}
.active{
color:red;
}
<div class="menu">
<ul>
<li>Home</li>
<li>News</li>
<li>ABC</li>
</ul>
</div>
With some JS or JQuery , Add a click event on your links and call a method
<div class="menu">
<ul>
<li>Home</li>
<li>News</li>
<li><a href="abc.jsp" click="MyMethod">ABC</li>
</ul>
</div>
and in Jquery(or JS) :
perform this :
YourLinkClicked.removeClass('active');
YourLinkClicked.addClass('active');

Modifying #לבני מלכה's answer to
a) Be a11y
b) Work with frameworks (like svelte)
c) Use events instead of the element itself (better for accessibility).
d) Have JSDoc Comments (for whoever must revise my code when this is old and non-modern).
Here is the HTML markup (pure HTML) :
<div class="navbar">
<ul>
<li><a onclick="change(e)" class="active">Link 1</a></li>
<li><a onclick="change(e)">Link 2</a></li>
</ul>
</div>
Pure JS (w/ JSDoc):
/**
* This function is used in the navbar. It gives styles to the active link.
* #param {Event | Undefined} e Event (click event).
*/
const change = (e) => {
if (!e) e = window.event; // <-- for Chrome <89, Firefox (I forgot versions), and Safari.
// If you have been used to JS for a bit, you may think that {} needs to be used above, but no. In modern JS, this is unnecessary. Of course, for multi-line if statements, you do need the brackets.
let list = document.querySelectorAll(".navbar ul li a");
list.forEach(elem => {
elem.classList.remove("active");
});
// Note the below comment is only if you are using a type checker, if you aren't then you can remove this. (the comment).
// #ts-ignore
e.target.classList.add('active');
}
The best and easy way to do it:
Just listen event on parent of list (ul)
After click find old active element and remove class for it
Set active class for target of event
document.querySelector('ul').addEventListener('click', event => {
// remove old active
document.querySelector('.menu .active').classList.remove('active');
// set new active
event.target.classList.add('active');
})
a {
color: #ccc;
text-decoration: none;
}
.active {
color: blue;
}
<div class="menu">
<ul>
<li><a class="active">Home</a></li>
<li><a>News</a></li>
<li><a>ABC</a></li>
</ul>
</div>
Here is some basic function i use for my current MVC project.
Add this to the master page or shared pages, the js need to run each time the site reload.
and you need to use jquery
$(document).ready(function () {
// the current page url eg /index.jsp
var href = window.location.href.toLowerCase();
$(".menu").find("a").each(function () {
// find the current li that match the current Url
if (href.indexOf($(this).attr("href").toLowerCase()) != -1)
$(this).addClass("active"); // set the current li to active
})
})
.acive{
color:red;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="menu">
<ul>
<li>Home</li>
<li>News</li>
<li><a href="abc.jsp">ABC</li>
</ul>
</div>

Custom style for markers in ace editor

Is it possible to set a custom style for an individual marker?
I'm trying to set the border color to a custom one for each marker I add, instead of using one single class. Those colors are ones I can't know in advance and I need to set them while the program is running. This is why I can't create a dozen classes and use them for this purpose.
You can use dynamic marker similar to what cloud9 uses here https://github.com/c9/core/blob/2d05ddeb7c0c1f6f3b35e305f60d1ba4f39f0294/plugins/c9.ide.collab/author_layer.js#L41 https://github.com/c9/core/blob/2d05ddeb7c0c1f6f3b35e305f60d1ba4f39f0294/plugins/c9.ide.collab/author_layer.js#L98
Here is one way you can do that: https://jsfiddle.net/sheriffderek/wkwzprfh/
markup
<ul class="marker-type-list">
<li class='marker-type'>
<button class='js-create-marker' data-color='red'>Create red marker</button>
</li>
<li class='marker-type'>
<button class='js-create-marker' data-color='green'>Create green marker</button>
</li>
<li class='marker-type'>
<button class='js-create-marker' data-color='blue'>Create blue marker</button>
</li>
</ul>
<ul class='marker-list'><!-- X --></ul>
script
$('.js-create-marker').on('click', function() {
var color = $(this).data('color');
console.log(color);
$('.marker-list').append('<li class="marker ' + color + '">marker</li>');
});
styles
.marker.red {
color: red;
}
.marker.green {
color: green;
}
.marker.blue {
color: blue;
}

How to disable a nav-pill hover effect just in one item in the navbar with Bootstrap?

I would like to disable the nav-pill hover effect on just one item, the link that changes the language of the page, in my navbar. What is the best way to achieve this using either a bootstrap class or CSS?
<div id="navbarCollapse" class="collapse navbar-collapse">
<ul class="nav nav-pills navbar-right">
<li class="language language-active disabled">NL</li>
<li class="language language-nonactive language-right">EN</li>
<li class="approach-li">Diensten</li>
<li class="about-li">Over ons</li>
<li class="qa-li">Vragen</li>
<li class="about-li">Contact</li>
<li class="navbarpadding">
<form action="afspraak.html">
<button class="btn navbar-btn btn-primary2">Afspraak maken</button>
</form>
</li>
</ul>
</div>
Looking at your html using the class: ".language-nonactive"
You can these styles to go along with it, this will remove the hover of the grey background:
.nav>li.language-nonactive>a:hover, .nav>li.language-nonactive>a:focus {
background-color: transparent;
}
Here is a jsfiddle to show what I've done:
http://jsfiddle.net/ho1sgm1e/
Additionally you could you something like this with jquery:
$(document).ready(function() {
/*disable non active tabs*/
$('.nav li').not('.active').addClass('disabled');
/*to actually disable clicking the bootstrap tab, as noticed in comments by user3067524*/
$('.nav li').not('.active').find('a').removeAttr("data-toggle");
});
source: Bootstrap tabs pills disabling and with jQuery
Furthermore, utilising the disbaled class will effectively disable the button.
Using CSS:
.nav .language-nonactive a:hover {
background:rgba(0,0,0,0);
}

Disabled dropdown menu items using twitter bootstrap

I use markup to display a dropdown menu using Twitter Bootstrap.
<ul class="nav pull-right">
<li class="dropdown">
Menu <b class="caret"></b>
<ul class="dropdown-menu">
<li>Menu item 1...</li>
<li class="divider"></li>
<li>Menu item 2...</li>
<li>Menu item 3</li>
</ul>
</li>
</ul>
I want to be able to make menu items appear disabled, i.e. no hover effect and probably a different text decoration to make the disabled state visible to the user.
What is the best way to accomplish this? Is there an exisisting bootstrap css class I can add to the <li> or <a> element?
When outputing the code for a disabled drop down, why not simply use :
<li class='disabled'>
Menu
</li>
You can always add the caret back if you still want it to appear.
Update:
Adding W3Schools Link
You can attach a custom disabled class to your menu link a tag that you want to disable and simply remove the default action by using preventDefault and targetting that class, like so:
$(".disabled-link").click(function(event) {
event.preventDefault();
});
Then you can style all events from the .disabled-link with a grey backdrop or any style you like;
CSS
a.disabled-link,
a.disabled-link:visited ,
a.disabled-link:active,
a.disabled-link:hover {
background-color:#d9d9d9 !important;
color:#aaa !important;
}
Demo
I prefer this (LESS):
/* Disable link */
a.disabled,
a.disabled:visited ,
a.disabled:active,
a.disabled:hover {
color: #999 ;
cursor: default;
}
.dropdown-menu {
a.disabled,
a.disabled:visited ,
a.disabled:active,
a.disabled:hover {
color: #999 ;
cursor: default;
background-color: white;
}
}
To disable the the dropdown use:
$('.dropdown-toggle').addClass('disabled');
To enable it back:
$('.dropdown-toggle').removeClass('disabled');
YES, Bootstrap has a predefined class with all necessary styling you need. You can simply add disabled class to whichever <li> you want
Just to add to Andres answer (don't have enough reputation to add comments :( ). You need to return false from the event handler or it might continue executing other handlers.
$(".disabled-link").click(function(event) {
event.preventDefault();
return false;
});
Similar to above you can use:
li.disabled > a {
color:#aaa !important;
}
This way you are keeping the same bootstrap default class for disabled links and implement the preventDefault() Javascript to disabled the link.
$(".disabled").click(function(event) {
event.preventDefault();
return false;
});
<div class="dropdown-menu">
<a class="dropdown-item" href="#">Regular link</a>
**<a class="dropdown-item disabled" href="#">Disabled link</a>**
<a class="dropdown-item" href="#">Another link</a>
</div>
Add .disabled to items in the dropdown to style them as disabled.

Dropdown menu - z-order

I have a dropdown menu:
<div class="buttons">
<div class="dropdown">
<span class="label">File</span><span class="toggle"></span>
<div class="dropdown-slider">
<span class="label">New</span>
<span class="label">Save</span>
</div> <!-- /.dropdown-slider -->
</div> <!-- /.dropdown -->
</div>
And here is js code:
<script>
$(document).ready(function() {
// Toggle the dropdown menu's
$(".dropdown .button, .dropdown button").click(function () {
$(this).parent().find('.dropdown-slider').slideToggle('fast');
$(this).find('span.toggle').toggleClass('active');
return false;
});
});
// Close open dropdown slider by clicking elsewhwere on page
$(document).bind('click', function (e) {
if (e.target.id != $('.dropdown').attr('class')) {
$('.dropdown-slider').slideUp();
$('span.toggle').removeClass('active');
}
});
</script>
If I put the two menus (one above other) I'll get popup menu below the second menu line.
How can I fix it?
Adding z-index:999; to div.dropdown-slider should fix your problem pretty quickly.
