How to disable popover behaviour for an inner element - javascript

I have a container with some details and a button inside it. and the container has popover behavior when we hover over it. the problem is I need to disable popover behavior while hovering over the button inside it. heres the fiddle Thanks in advance.
<div class="container">
<p>name: </p>
<p>age: </p>
<p>department:</p>
<button class="btn btn-primary">Connect</button>
</div>
$('.container').popover({
trigger: "hover",
content: "sample content"
})

Add below codes into JavaScript block.
$('.container button').mouseover(function(e) {
$('.container').popover('hide');
});
$('.container button').mouseout(function(e) {
$('.container').popover('show');
});

You can do like this:
$('.container button').hover(function(){
$('.container').popover('hide');
},function(){
$('.container').popover('show');
});
Fiddle: https://jsfiddle.net/fwcrt2hy/

I suggest...
$('.container p').popover({
trigger: "hover",
content: "sample content"
});
(i.e. changing the selector to .container p) because the only content in your .container besides the <button> is paragraph (<p>) elements.
Possible Drawbacks
If your .container has padding, the padding area will not trigger the popover behavior.

You can use selector option within popover() method. If a selector is provided, popover objects will be delegated to the specified targets. In practice, this is used to enable dynamic HTML content to have popovers added.
$(function () {
$('.container').popover({
trigger: "hover",
content: "sample content",
selector: 'p' //added this line
})
});

Bootstrap - popover inside a popover

I'm attempting to put a bootstrap popover inside another popover. The first popup functions correctly (opens and has the HTML content specified) but the second, while opening properly seems to not have any of the settings I set enabled (html:true, trigger:'manual', or the html content). See the demo below:
Fiddle
<div>
Click
<div id="popover_content_wrapper1" style="display: none">
Click again
</div>
<div id="popover_content_wrapper2" style="display: none">
<b>Hello world</b>
</div>
</div>
$('#popover1').popover({
html: true,
trigger: 'manual',
content: function() {
return $('#popover_content_wrapper1').html();
}
});
$(document).on('click', '#popover1', function() {
$(this).popover('toggle');
});
$('#popover2').popover({
html: true,
trigger: 'manual',
content: function() {
return $('#popover_content_wrapper2').html();
}
});
$(document).on('click', '#popover2', function() {
$(this).popover('toggle');
});
I'd appreciate any tips/help.
Thanks!
That happens because at the time you initialize #popover2, it still doesn't "exists". It will only exists once the #popover1 is toggled.
So, you have to initialize it every time you toggle #popover1, because when it hides, it is removed from DOM (children included)
$(document).on('click', '#popover1', function() {
$(this).popover('toggle');
$('#popover2').popover({
html: true,
trigger: 'manual',
content: function() {
return $('#popover_content_wrapper2').html();
}
});
});

As bootstrap does not support popover inside a popover, I have initialised popover inside the content of the first popover. You can simply add following javascript code in the first popover content as follows.
<script>
jQuery(function () {
jQuery('[data-toggle="popover"]').popover();
});
</script>
Hope it can help.

jQuery binding events to elements with dynamic class

I have a trigger element and a responding element.
<div class="more"></div>
<div class="info"></div>
I would like to bind an open/close type event.
$('.more').delegate($('.more'), 'click', function(){
$(this).removeClass('more');
$(this).addClass('less');
$(this).text("less...");
$('.info').addClass("open");
});
$('.less').delegate($('.less'), 'click', function(){
$(this).addClass('more');
$(this).removeClass('less');
$(this).text("more...");
$('.info').removeClass("open");
});
It doesn't work as intended, if the second function is nested in the first then you can open and close only once.
If the script is formatted sensibly as above it will open but not close.
Could anyone help me out?
Bonus if the script could support the .info could be either a sibling or the element immediately following $(.more/.less)'s parent.
I've been toying with .on/.live/.bind but less successfully than above.
Use event delegation ,and binded to document or immediate parent,not same element
$(document).on( 'click',".more", function(){
$(this).removeClass('more');
$(this).addClass('less');
$(this).text("less...");
$('.info').addClass("open");
});
$(document).on('click',".less", function(){
$(this).addClass('more');
$(this).removeClass('less');
$(this).text("more...");
$('.info').removeClass("open");
});
DEMO
NOTE: delegate was outdated with latest version of jquery ,so use on instead,
ISSUE: you are delegated with same element $('.less'),$('.more') use immediate parent or document
Just use JavaScript to toggle a class, and let CSS magic do the rest. Here is a demo: http://jsfiddle.net/pomeh/69sX5/1/
And here is the code:
HTML
<div>
Some visible content
</div>
<div class="content-fold">
<div class="more">More...</div>
<div class="less">Less...</div>
</div>
<div class="info">Some hidden additional content</div>
CSS
/* Additional content and Less button hidden by default */
.content-fold + .info, .content-fold .less {
display: none;
}
/* Additional content and Less button shown when class shown is active */
.content-fold.shown + .info, .content-fold.shown .less {
display: block;
}
/* More button hidden when additional content is shown */
.content-fold.shown .more {
display: none;
}
/*
You can also move the "div.info" into the "div.content-fold",
and use ".content-fold.shown > .info" instead of ".content-fold.shown + .info"
Browser support is quite good for adjacent selector (see http://www.quirksmode.org/css/selectors/#t11 and https://developer.mozilla.org/en-US/docs/Web/CSS/Adjacent_sibling_selectors#Browser_compatibility)
*/
JavaScript
$('.content-fold').on('click', function(){
$(this).toggleClass('shown');
});
Use id to do your task. it's easy.
Html
<div class="more" id="toggle"></div>
<div class="info"></div>
Jquery
$('#toggle').click(function(){
var $this = $(this) //store object
if($this.hasClass('more')) {
$this.removeClass('more').addClass('less').text('Less...')
$this.next('.info').addClass('open');
} else {
$this.removeClass('less').addClass('more').text('More...')
$this.next('.info').removeClass('open');
}
});

How to show the child div on mouse hover of parent div

I have a number of parent divs (.parent_div), which each contain a child div (.hotqcontent) where I output data from my database using a loop.
The following is my current markup:
<div class="content">
<div class="parent_div">
<div class="hotqcontent">
content of first div goes here...
</div>
<hr>
</div>
<div class="parent_div">
<div class="hotqcontent">
content of second div goes here...
</div>
<hr>
</div>
<div class="parent_div">
<div class="hotqcontent">
content of third div goes here...
</div>
<hr>
</div>
<div class="parent_div">
<div class="hotqcontent">
content of fourth div goes here...
</div>
<hr>
</div>
</div>
What I would like to achieve is when a user hovers / mouseovers a parent div, the contents of the child div contained within should be revealed.
To achieve this I wrote the following jQuery script but it doesn't appear to be working. It's not even showing the alert!
<script>
$(document).ready(function() {
$(function() {
$('.parent_div').hover(function() {
alert("hello");
$('.hotqcontent').toggle();
});
});
});
</script>
How can I modify or replace my existing code to achieve the desired output?
If you want pure CSS than you can do it like this....
In the CSS below, on initialization/page load, I am hiding child element using display: none; and then on hover of the parent element, say having a class parent_div, I use display: block; to unhide the element.
.hotqcontent {
display: none;
/* I assume you'll need display: none; on initialization */
}
.parent_div:hover .hotqcontent {
/* This selector will apply styles to hotqcontent when parent_div will be hovered */
display: block;
/* Other styles goes here */
}
Demo
Try this
$(document).ready(function() {
$('.parent_div').hover(function() {
alert("hello");
$(this).find('.hotqcontent').toggle();
});
});
Or
$(function() {
$('.parent_div').hover(function() {
alert("hello");
$(this).find('.hotqcontent').toggle();
});
});
You can use css for this,
.parent_div:hover .hotqcontent {display:block;}
This can be done with pure css (I've added a couple of bits in just to make it a bit neater for the JSFIDDLE):
.parent_div {
height: 50px;
background-color:#ff0000;
margin-top: 10px;
}
.parent_div .hotqcontent {
display: none;
}
.parent_div:hover .hotqcontent {
display:block;
}
This will ensure that your site still functions in the same way if users have Javascript disabled.
Demonstration:
http://jsfiddle.net/jezzipin/LDchj/
With .hotqcontent you are selecting every element with this class. But you want to select only the .hotqcontent element underneath the parent.
$('.hotqcontent', this).toggle();
$(document).ready(function(){
$('.parent_div').on('mouseover',function(){
$(this).children('.hotqcontent').show();
}).on('mouseout',function(){
$(this).children('.hotqcontent').hide();
});;
});
JSFIDDLE
you don't need document.ready function inside document.ready..
try this
$(function() { //<--this is shorthand for document.ready
$('.parent_div').hover(function() {
alert("hello");
$(this).find('.hotqcontent').toggle();
//or
$(this).children().toggle();
});
});
and yes your code will toggle all div with class hotqcontent..(which i think you don't need this) anyways if you want to toggle that particular div then use this reference to toggle that particular div
updated
you can use on delegated event for dynamically generated elements
$(function() { //<--this is shorthand for document.ready
$('.content').on('mouseenter','.parent_div',function() {
alert("hello");
$(this).find('.hotqcontent').toggle();
//or
$(this).children().toggle();
});
});
you can try this:
jQuery(document).ready(function() {
jQuery("div.hotqcontent").css('display','none');
jQuery("div.parent_div").each(function(){
jQuery(this).hover(function(){
jQuery(this).children("div.hotqcontent").show(200);
}, function(){
jQuery(this).children("div.hotqcontent").hide(200);
});
});
});

How do I make this code work for each click?

I have h3 block's and on click of each of the block I am showing the section associated with it. It is actually something like accordion(hide and collapse). I have also given a drop icon to the h3 tags, means that when the block is opened the h3 should have a dropicon pointing downwards while others h3 should have there dropocons towards right. I am controlling this behaviour using backgroundPosition. I am using the jQuery visible condition to see if the particular block is visible then give its drop icon one background position and to the rest other. It works fine but only for first click. It doesn't work for second click; can somebody explain why? Here is my code:
if($(this).next().is(':visible')) {
$(this).css({'backgroundPosition':'0px 14px'});
}
else {
$("h3").css({'backgroundPosition':'0px -11px'});
}
UPDATED CODE:
$("h3").click(function() {
$(".tabs").hide();
$(this).next().show();
if($(this).next().is(':visible')) {
$(this).css({'backgroundPosition':'0px 14px'});
} else {
$("h3").css({'backgroundPosition':'0px -11px'});
}
})
If you wrap the whole block in a div it might make traversing easier.
Html:
<div class="drop-block">
<h3>Click this</h3>
<ul>
<li>Drop</li>
<li>it</li>
<li>like</li>
<li>it's</li>
<li>hot</li>
</ul>
</div>​
Jquery:
var dropper = $('.drop-block');
$(dropper).find('h3').click(function(){
$(this).toggleClass('active');
$(dropper).find('ul').toggle();
});​
Example
I Belive that you are looking for live
So it will be something like this:
$(element).live('click', function(){
if($(this).next().is(':visible')) {
$(this).css({'backgroundPosition':'0px 14px'});
}
else {
$("h3").css({'backgroundPosition':'0px -11px'});
}
}
Instead of editing the css of them, make a css class "open" (or similar), and then add / remove the class on the click to open / close.
It is much easier to debug by checking for the existence of a class than it is to check the css properties of something in JS.
Better make a class name for each situation and easly handle the action
$('h3').on('click', function(){
if($(this).hasClass('opened')) {
$(this).removeClass('opened');
}
else {
$(this).addClass('opened');
}
}
$(document).on('click', 'h3', function(e) {
$(".tabs").hide('slow');
$(this).css({'backgroundPosition':'0px 14px'});
if(!$(this).next().is(':visible'))
{
$("h3").css({'backgroundPosition':'0px -11px'});
$(this).next().show('slow');
}
});
You can remove 'slow' from show/hide if animation is not required
Here is an example.
It sounds like you need to bind click events to the h3 elements and toggle the visibility of the child elements:
$(function(){
$("h3").click(function(){
$(this).next(".tabs").toggle();
});
});
Example markup:
<h3>Item 1</h3>
<div class="tabs">
<h4>Option 1</h4>
<h4>Option 2</h4>
</div>
<h3>Item 2</h3>
<div class="tabs">
<h4>Option 1</h4>
<h4>Option 2</h4>
</div>
Here's a jsFiddle to demonstrate.

How to implement a blinds toggle effect with jQuery

I'm trying to write a "blinds" function that would close a DIV in a display:none mode. The unseen DIV is inside a wider DIV, containing the blind trigger.
This:
$(document).ready(function () {
$("#toggle_blind").click(function () {
$(this).toggle("fast");
});
});
Well, this blinds the button. How can I add a DIV to $this? Something like:
<div id="blind" class="wider_div">
<h3 id="closeButton">Close</h3>
<div style="display:none;" id="closeThis">
<p>some text</p>
</div>
</div>
How do I make the Close Button on H3 to close/open the CloseButton DIV on each click?
The div is the next sibling of the h3 so you can use .next()
E.g
$('#closeButton').click( function(){
$(this).next().toggle();
});
Reference the div directly, you may put something else in between it and the h3.
$(document).ready(function()
{
$("#closeButton").click(function()
{
$("#closeThis").toggle("fast");
});
});
