jQuery mouseenter/leave - javascript

I have this code in html:
<div class="sub-status">
<p class="subscribed"><i class="icon-check"></i> Subscribed</p>
</div>
On hover, I want that to be changed to:
<div class="sub-status">
<p class="unsubscribe"><i>X</i> Unsubscribe</p>
</div>
And, I have this code in jQuery:
$(document).ready(function() {
$('.sub-status').mouseenter(function() {
$(this).html("<p class='unsubscribe'><i>X</i> Unsubscribe</p>");
});
$('.sub-status').mouseleave(function() {
$('this').html("<p class='subscribed'><i class='icon-check'></i> Subscribed</p>");
});
});
The first function is working great. When I mouseover that div, it is changed to what I want, but the mouseleave is not working. I want that when I put my mouse out of that div, its data will return to like it was before. I can't get this working. Any help would be appreciated.
Thanks.

Change
$('this')...
to
$(this)...
And you can use hover() instead of using two separate functions:
$('.sub-status').hover(function() {
$(this).html("<p class='unsubscribe'><i>X</i> Unsubscribe</p>");
},function() {
$(this).html("<p class='subscribed'><i class='icon-check'></i> Subscribed</p>");
});
Updated
Your fiddle isn't working since you are updating the entire content of the hovered element - update just the text in <p> should work.
$('.sub-status').hover(function() {
$(this).children('p')
.removeClass()
.addClass('unsubscribed')
.html("<i>X</i> Unsubscribe");
},function() {
$(this).children('p')
.removeClass()
.addClass('subscribed')
.html("<i class='icon-check'></i> Subscribed");
});
Working fiddle

Here, try this. Working demo: http://jsfiddle.net/XrYj4/3/
$(document).ready(function() {
$('.sub-status').on("mouseenter", function() {
$(this).find("p").prop("class", "unsubscribed").html("<i>X</i> Unsubscribe");
}).on("mouseleave", function() {
$(this).find("p").prop("class", "subscribed").html("<i class='icon-check'></i> Subscribed");
});
});

Try to use a hover function:
$(".sub-status").hover(
function () {
$(this).html("<p class='unsubscribe'><i>X</i> Unsubscribe</p>");
},
function () {
$(this).html("<p class='subscribed'><i class='icon-check'></i> Subscribed</p>");
}
);

Change 'this' to simply this. Also consider chaining, shown below, this helps users with weaker devices load stuff faster.
$(document).ready(function() {
$('.sub-status').mouseenter(function() {
$(this).html("<p class='unsubscribe'><i>X</i> Unsubscribe</p>");
}).mouseleave(function() {
$(this).html("<p class='subscribed'><i class='icon-check'></i> Subscribed</p>");
});
});

Jquery click function for toggle is not working

I have a scenario,where footer must be collapsed based on device.Here,I used toggle class for collapse in mobile device,the toggle click is not working.
JavaScript code:
// Code goes here
$(function() {
$('.footer-links-holder h3').click(function () {
$(this).parent().toggleClass('active');
});
});
Plunker
Any help would be appreciated.
Thanks in Advance.
Just write your JS like this -
$('.footer-links-holder h3').click(function () {
$(this).parent().toggleClass('active');
});
Your updated Plunker
Batter practice is write code in ready function
$(document).ready(function(){
$('.footer-links-holder h3').click(function () {
$(this).parent().toggleClass('active');
});
})
$(function() {
$('.footer-links-holder h3').off().click(function () {
$(this).parent().toggleClass('active');
});
});

Jquery on hover and out

I am trying to hide a div whenever I will hover over it and show another one in the same place.. And when I take the mouse out of that.. the previous div will be shown and this div will be hidden...
$(document).ready(function(){
$('#hover_tutor').hover(
function () {
$('#hover_tutor').hide();
$('#hover_tutor_hidden').show();
},
function () {
$('#hover_tutor').show();
$('#hover_tutor_hidden').hide();
}
);
});
<div id="hover_tutor">Blah</div>
<div id="hover_tutor_hidden" style="display:none;">Bleh</div>
But on hovering the hover_tutor... something is happening.. It's jumping up and down.. I don't know what's wrong...
You need to use .mouseenter event for #hover_tutor div and .mouseleave for #hover_tutor_hidden div:
$('#hover_tutor').mouseenter(function () {
$(this).hide();
$('#hover_tutor_hidden').show();
});
$('#hover_tutor_hidden').mouseleave(function () {
$('#hover_tutor').show();
$(this).hide();
}
).mouseleave();//trigger mouseleave to hide second div in beginning
Working Demo
You can also use toggle method instent of hide/show on hover event
<div id="hover_tutor" style="display: block;">Blah</div>
<div id="hover_tutor_hidden" style="display: none;">Bleh</div>
$('#hover_tutor').hover(
function () {
$('#hover_tutor').toggle();
$('#hover_tutor_hidden').toggle();
});
Working demo
http://jsfiddle.net/ivyansh9897/8jgjvkqk/
try this,
$('#hover_tutor').hover(function () {
$(this).hide();
$('#hover_tutor_hidden').show();
});
$('#hover_tutor_hidden').hover(function () {
$('#hover_tutor').show();
$(this).hide();
}
));
If you do have the flexibility to modify your html little bit using class attribute there's a better way. Use .toggle() to alter the state of your element on both mouseover and mouseleave.
HTML :
<div id="hover_tutor" class="hello">Blah</div>
<div id="hover_tutor_hidden" class="hello" style="display:none;">Bleh</div>
jQuery :
$(".hello").on("mouseover mouseleave", function(){
$("#hover_tutor").toggle();
$("#hover_tutor_hidden").toggle();
});

Show/Hide after a div created dynamically

I use this code to show/display Edit link when mouse hovers over the start div. This div however can be created dynamically and when it's created the code below doesn't work.
$(".start").hover(
function() {
timeclock.utils.displayEdit(this)
},
function() {
timeclock.utils.hideEdit(this)
});
I tried the code below but it doesn't work and it looks wrong. How can I implement $(document).on('hover'.....) to hide/show the Edit link as shown above?
$(document).on("hover", ".start",
function() {
timeclock.utils.displayEdit(this)
},
function() {
timeclock.utils.hideEdit(this)
});
hover() is a shortcut for binding mouseenter and mouseout handlers. Your second example doesn't work because on() doesn't take two functions like that. You bind multiple handlers at once using delegated events like this:
$(document).on({
mouseenter: function () {
timeclock.utils.displayEdit(this);
},
mouseleave: function () {
timeclock.utils.hideEdit(this);
}
}, '.start');
Simple example: http://jsfiddle.net/TRcR9/
There are 2 errors in your code.
1. you should use $(this) instead of this. There is a different between this two.
2. you have to bind the hover again whenever a new div is created.
Your syntax is a little off. You can attach multiple event handlers simultaneously using a plain object.
$(document).on({
mouseenter: function(){
timeclock.utils.displayEdit(this);
},
mouseleave: function(){
timeclock.utils.hideEdit(this);
}
}, ".start");
I've created a Codepen example here: http://cdpn.io/dDewi
The syntax you have is a a little off. Here is a jsfiddle with a working example:
HTML:
<div id="container"></div>
CSS:
#edit { display: none; }
Javascript:
$(function() {
$(document).on(
{
mouseenter: function()
{
$('#edit').show();
},
mouseleave: function()
{
$('#edit').hide();
}
},
'.start'
);
$('#container').prepend('<div class="start">Mouse over me <a id="edit" href="#">edit</a></div>');
});

Can't hide element on click for some reason

I have an element on my website, it looks like so:
<div class="nw_help"><div class="nw_help_content">...</div></div>
Easy stuff. Using CSS on nw_help:hover, nw_help_content becomes visible. In order to support touchscreens too, I have written the following:
$(document).ready(function() {
$('.nw_help').click(function() {
$(this).find(".nw_help_content").css('visibility', 'visible');
});
});
$(document).ready(function() {
$('.nw_help_content').click(function() {
$(this).css('visibility', 'hidden');
});
});
The first function works flawlessly, the second one doesn't wanna work at all. I've checked if $('.nw_help_content').css('visibility', 'hidden'); is working in browser's console and it is.
Any ideas?
Thanks so much in advance for your answer.
Edit: Now it hit me: the first function is triggered on clicking nw_help_content as well and it "neutralizes" the second function. But how to prevent it?
I believe if you have the visibility hidden on page render, the element is never rendered. You'll need event delegation:
$(document).ready(function() {
$('.nw_help').click(function() {
$(this).find(".nw_help_content").css('visibility', 'visible');
});
$(document).on('click', '.nw_help_content', function() {
$(this).css('visibility', 'hidden');
});
});
Also, only one DOM ready statement is needed.
Demo: http://jsfiddle.net/7sM3L/4/
I suggest staying away from direct CSS rule manipulation on this. Just using jQuery show and hide will provide a more solid/reliable result.
$(document).ready(function() {
$('.nw_help').click(function() {
$(this).find('.nw_help_content').show();
});
});
$(document).ready(function() {
$('.nw_help_content').click(function() {
$(this).hide();
});
});
It is actually working/ Since the divs are nested you are both events fire and the div is hidden and shown on same click.
use toggle instead.
$(document).ready(function() {
$('.nw_help').click(function() {
$(this).find(".nw_help_content").toggle();
});
});
Check out the fiddle
As Zenith says, this is due to event bubbling... Another solution is to bind the event only to the outer container and simply check for the visibilty:
$(document).ready(function() {
$('.nw_help').click(function() {
var content = $(this).find('.nw_help_content');
if(content.css('visibility') == 'hidden') {
content.css('visibility','visible');
} else {
content.css('visibility','hidden');
}
});
});

JQuery: .index() returns -1

Here's main part of html:
<div id="table">
<div class="table_item">asd</div>
<div class="table_item">asd</div>
<div class="table_item">asd</div>
</div>
And JS (JQuery):
$(document).ready( function()
{
$(".table_item").click( function()
{
alert($("#table").index($(this)));
});
});
click handling works but I ALWAYS get -1 from .index.
trying simply $(this).index(); shows the same result.
Please help! What's wrong with the code?
Do this instead:
$(document).ready( function()
{
var ti = $('.table_item');
ti.click( function()
{
alert(ti.index(this));
});
});
EDIT: Someone had a post that was deleted that was correct, and I think a little better than my code above:
$(document).ready( function()
{
$('.table_item').click( function()
{
alert($(this).index());
});
});
Working examples of both solutions: http://jsfiddle.net/FishBasketGordo/rx5e7/
You need to call index on a collection, in this case divs with class table_item
alert($(".table_item").index(this));
Since you are attaching a click() listener to $(".table_item"), you can reference the object by using $(this).
Try:
$(document).ready( function()
{
$(".table_item").click( function()
{
alert($(this).index());
});
});
