I'm struggling to select my img Element in a list so i can switch its class on and off.
I've tried different way to select it but its the first picture of my list that lights up, even when mouseover on the second/third/... div of the list.
<ul>
<li>
<div class="container" onmouseover="toggleImgColor()" onmouseout="toggleImgColor()">
<div class="container-title">
<h3 class="title />
<img id="pic" class="greyImg" />
</div>
...
</div>
</li>
...
</ul>
Javascript
function toggleImgColor() {
$(this).find("img").toggleClass("greyImg");
}
You can do that something like this:
$(document).ready(function(){
$(".container").hover(function() {
$("#pic").toggleClass("greyImg");
});
});
Just pass this inside the toggleImgColor() in html like toggleImgColor(this), and catch that as parameter in javascript function. This will pass current hovered DOM object to toggleImgColor function and you can then use that to show that specific div.
HTML:
<ul>
<li>
<div class="container" onmouseover="toggleImgColor(this)" onmouseout="toggleImgColor(this)">
<div class="container-title">
<h3 class="title />
<img class="greyImg" />
</div>
...
</div>
</li>
...
</ul>
JavaScript:
function toggleImgColor(item) {
$(item).find("img").toggleClass("greyImg");
}

I have multiple(it can be 100+) collapsible div (using bootstrap)
<div>
<a href="#id1" data-toggle="collapse">
<div class="col-lg-12">Title</div>
<div class="image">Image</div>
</a>
<div id="id1" class="collapse">
<div class="col-lg-12">Description</div>
</div>
</div>
<div>
<a href="#id2" data-toggle="collapse">
<div class="col-lg-12">Title</div>
<div class="image">Image</div>
</a>
<div id="id2" class="collapse">
<div class="col-lg-12">Description</div>
</div>
</div>
And have Jquery
$('#id1').on('show.bs.collapse', function () {
$(".image").addClass('hidden');
});
$('#id1').on('hidden.bs.collapse', function () {
$(".image").removeClass('hidden');
});
I want to add hidden class on show.bs.collapse(this is from bootstrap) and remove hidden class on hidden.bs.collapse'With the jq code above I can do this just with one div that has id1. But how can I do this independently?
Try not to subscribe on the elements by ids but by element type
$('a').on('show.bs.collapse', function () {
$(this).next().find("div.image")[0].addClass('hidden');
});
$('a').on('hidden.bs.collapse', function () {
$(this).next().find("div.image")[0].removeClass('hidden');
});
Where
$(this)
should return a pointer to the collapsed/uncollapsed element
next()
should move pointer to the next element ( div id="id1" as example)
find("div.image")[0]
will find div with class "image" and take the first found element
then you can hide the image in this block or show it without using ids
If you're using
$(".image").addClass('hidden');
this will hide all the images in all blocks (not only in that one that has been collapsed)
Id refers to one element on the DOM therefore you should use classes instead. Therefore you should select divs based on their classes.
The following is a possible solution:
<div>
<a href="#id1" data-toggle="collapse">
<div class="col-lg-12">Title</div>
</a>
<div class="some-class collapse ad-col-2">
<div class="col-lg-12">Description</div>
<div class="image"></div>
</div>
</div>
<div>
<a href="#id2" data-toggle="collapse">
<div class="col-lg-12">Title</div>
</a>
<div class="some-class collapse ad-col-2">
<div class="col-lg-12">Description</div>
<div class="image"></div>
</div>
</div>
Jquery:
$('.some-class').on('show.bs.collapse', function () {
$(".image").addClass('hidden');
});
$('.some-class').on('hidden.bs.collapse', function () {
$(".image").removeClass('hidden');
});
There is a bootstrap carousel that is changing automatically:
<div id="carousel">
<div class="active"> </div>
<div class=""> </div>
<div class=""> </div>
<div class=""> </div>
</div>
Only one div is set to active at a time, and it cycles through like that.
How can I bind all of carousel's children to another element so that it can set it's specific child to be active as well.
For example:
<div id="copy-cat">
<li class=""> </li>
<li class=""> </li>
<li class=""> </li>
<li class=""> </li>
</div>
<div id="carousel">
<div class="active"> </div>
<div class=""> </div>
<div class=""> </div>
<div class=""> </div>
</div>
How can I bind copy-cat to have the same child active as carousel? Keep in mind, I don't want to copy all of the class attributes- just detect that one is active, and set that same numbered child to active also.
I'd use Bootstrap's slid event callback:
http://jsfiddle.net/isherwood/6xF7k/
$('#carousel').on('slid.bs.carousel', function () {
// get the index of the currently active panel
var myIndex = $(this).find('div.active').index();
// set the element with that index active, deactivating the others
$('#copy-cat').find('li').removeClass('active').eq(myIndex)
.addClass('active');
})
Notice that I changed #copy-cat to ul to make it valid HTML.
http://getbootstrap.com/javascript/#carousel-usage
Given an element x, you can get the index of x in its parent's .children() by calling x.index(). In your example, $("div.active").index() would return 0, the div following would return 1, etc. So you should be able to do something like the following:
$("#copy-cat :nth-child("+(1+$("#carousel div.active").index()) + ")").addClass("active");
(nth-child is 1-index-based, so you need to add 1. You could also call eq(), which is 0-based.)
See this jsFiddle for a rough example.
But this is only a general answer. If there are Bootstrap methods for this purpose, by all means use them.
The Bootstrap carousel has some events that you can tap into.
Information about the events can be found in the "Events" section under the Carousel documentation.
I would recommend doing something like:
<div id="copy-cat">
<div id="copy-1" class="active"></div>
<div id="copy-2" class=""></div>
<div id="copy-3" class=""></div>
<div id="copy-4" class=""></div>
</div>
<div id="carousel" class="carousel slide">
<div class="carousel-inner">
<div class="item active" data-transition-to="#copy-1">
<p>something1</p>
</div>
<div class="item" data-transition-to="#copy-2">
<p>something2</p>
</div>
<div class="item" data-transition-to="#copy-3">
<p>something3</p>
</div>
<div class="item" data-transition-to="#copy-4">
<p>something4</p>
</div>
</div>
</div>
Add a listener as described in the event section, and inspect the relatedTarget.
Use the data-transition-to to figure out the class to add the active class to.
Javascript to support this approach:
$('#carousel').carousel({
interval:false //or whatever options you want
});
$('#carousel').on('slide.bs.carousel',function (event) {
$('#copy-cat .active').removeClass('active');
$(event.relatedTarget.dataset.transitionTo).addClass('active');
});
$('#carousel').carousel('next');
This is is the fiddle ...I disabled transitioning & you will have to inspect the DOM to see that the copy-cat div is being changed.
When storing DOM elements in a javascript variable prior to appending them to the actual DOM is there a way with jQuery to select elements inside the variable?
For example,
I have a list of tweets on my page. Every time I click a refresh button I append a new tweet to the list below.
I add the new tweet like follows:
new tweet
<li class="tweet normal-tweet" data-user-name="Dorothy">
<div class="image">
<img height="48" width="48" src="http://twitter.com/api/users/profile_image?screen_name=Dorothy" alt="" />
</div>
<div class="content">
<div class="user">
<a class="user-name" href="http://twitter.com/Dorothy" title="Dorothy">Dorothy</a>
<div class="full-name"></div>
</div>
<div class="text">Once in a lullaby</div>
<div class="time-stamp" data-time="1322631934000">1322631934000</div>
</div>
</li>
Inside each tweet on the page, not the new tweet yet, I use jQuery to append some elements.
I have:
var actionsMarkup =
"<div class='actions'>
<span class='favorite'>Favorite</span>
<span class='retweet'>Retweet</span>
<span class='reply'>Reply</span>
</div>";
and I append it to the element with the .content class
$(actionsMarkup).appendTo('#tweets .tweet .content');
Now, when I make a new tweet I do the following:
$(document).on('click', '.refresh', function() {
newTweet = $(<new tweet code from above>);
actionsMark = $(actionsMarkup);
$(newTweet.appendTo('#tweets');
I need to be able to append the actionsMark contents to the div with class .content. However, I can't just reapply my prior statement of
$(actionsMarkup).appendTo('#tweets .tweet .content');
because that puts the markup on all .content divs again, even if it is already there.
Is there a way for me to use selectors to access the DOM nodes in my newTweet variable before I append it to the document object?
I am thinking something like
$(actionsMarkup).appendTo( newTweet, '.content');
If there is no way with selectors to do this then what are some other quick ways?
List of Tweets and Tweet container
<ul id="tweets" class="normal-tweet show-promoted-tweets">
<li class="tweet promoted-tweet" data-user-name="Dorothy">
<div class="image">
<img height="48" width="48" src="http://twitter.com/api/users/profile_image?screen_name=Dorothy" alt="" />
</div>
<div class="content">
<div class="user">
<a class="user-name" href="http://twitter.com/Dorothy" title="Dorothy">Dorothy</a>
<div class="full-name">Dorothy</div>
</div>
<div class="text">Somewhere over the rainbow</div>
<div class="time-stamp" data-time="1322631934000">3 minutes ago</div>
</div>
</li>
<li class="tweet promoted-tweet" data-user-name="lion">
<div class="image">
<img height="48" width="48" src="http://twitter.com/api/users/profile_image?screen_name=lion" alt="" />
</div>
<div class="content">
<div class="user">
<a class="user-name" href="http://twitter.com/lion" title="lion">lion</a>
<div class="full-name">Lion</div>
</div>
<div class="text">Way up high,</div>
<div class="time-stamp" data-time="1322631934000">17 minutes ago</div>
</div>
</li>
<li class="tweet normal-tweet" data-user-name="scarecrow">
<div class="image">
<img height="48" width="48" src="http://twitter.com/api/users/profile_image?screen_name=scarecrow" alt="" />
</div>
<div class="content">
<div class="user">
<a class="user-name" href="http://twitter.com/scarecrow" title="scarecrow">scarecrow</a>
<div class="full-name">Scarecrow</div>
</div>
<div class="text">And the dreams that you dreamed of,</div>
<div class="time-stamp" data-time="1322631934000">32 minutes ago</div>
</div>
</li>
</ul>
You can use .last(), to select the last element after you append your new tweet, like below:
$(document).on('click', '.refresh', function() {
newTweet = $(<new tweet code from above>);
$(newTweet).appendTo('#tweets');
var actionsMarkup =
"<div class='actions'>
<span class='favorite'>Favorite</span>
<span class='retweet'>Retweet</span>
<span class='reply'>Reply</span>
</div>";
$("#tweets .tweet").last().find(".content").append(actionsMarkup);
});
if you insist to use appendTo(), you can try using :last-child:
$(actionsMarkup).appendTo('#tweets .tweet:last-child .content');
I was looking to see if you can do the same thing, found this question but the existing answer is not useful in my case as i would like to alter the element before adding.
You can create a new dom element in a variable with jQuery and do operations on it as if it is already in the dom before appending it.
Example:
var newTweet = $('<div></div>');
newTweet.addClass('tweet');
newTweet.append('<span class="username"></span>');
newTweet.find('span.username').html('John Doe');
$('body').append(newTweet);
the following will be appended to the body:
<div class="tweet"><span class="username">John Doe</span></div>
Very handy if you are building a reusable interface element (like a dialogue box) with multiple options.
I am new to jQuery and am trying to write a script that will run through a menu list and display the correct background image based on the menu item. The menu list is going to be randomly populated so a script is necessary to load the correct image.
The problem is that the attribute where I am able to see which item the menu belongs to is not on the list item itself but on a div contained inside the list item. My question is is it possible to select a child element of the already selected element ?
E.g (the menuli a segment)
$(document).ready( function() {
$(menuli).each( function(index) {
$itemnumber = $(menuli a).attr("href");
switch($itemnumber) {
case 1:
$(this).css("background-image", "image01.jpg");
break;
}
});
});
This is more or less the script I am trying to get, where each list item is iterated through and depending on the href of the link inside the list item a background image is set to that list item.

Yes you can, use find
var parentElement = $('#someElement');
var childElement = parentElement.find('.child'); //where .child should be your child selector
Where as example code is not clear, I just gave answer to your question.
try to change this:
$(this).css("background-image", "image01.jpg");
to this:
$(this).children("div").css("background-image", "image01.jpg");
If you want to target the direct child of the element, better to use children() than find()
Please refer to this: What is fastest children() or find() in jQuery?
I have 2 questions:
1) Since I have similar structure for the html contents and the only difference is that class title contents are different. I tried using $(div .title:contains("cat")) also
$(div .title).text()="cat")
2)How can I get the index of the accordion by just checking the $(div a) contents are required ones. I tried using $(div a).text()=="cat"
Check the codes here:
HTML1 contents
<div class="mod moduleselected" id="mod969">
<div class="content module moduleselect">
<div class="hd" ><div class="inner">
<div class="title">cat</div>
<ul class="terminallist"></ul>
<ul class="buttons">
<li class="help"></li>
<li class="show" ></li>
</ul>
</div>
</div>
</div>
<div class="mod moduleselected" id="mod969">
<div class="content module moduleselect">
<div class="hd" ><div class="inner">
<div class="title">rat</div>
<ul class="terminallist"></ul>
<ul class="buttons">
<li class="help"></li>
<li class="show" ></li>
</ul>
</div>
</div>
</div>
<div class="mod moduleselected" id="mod969">
<div class="content module moduleselect">
<div class="hd" ><div class="inner">
<div class="title">dog</div>
<ul class="terminallist"></ul>
<ul class="buttons">
<li class="help"></li>
<li class="show" ></li>
</ul>
</div>
</div>
</div>
Accordian
<div id="dia">
<div id="dialog" title="Detailed FeedBack ">
<div id="accordion">
<h3>dog</h3>
<h3>cat</h3>
<h3>rat</h3>
</div>
</div>
</div>
Javascript
$('div .title').mouseover(function() {
if($("div a").text().indexOf("cat")!=-1)
{
$("#accordion").accordion("activate", 1);
}
$('div .title').mouseleave(function(){$("#accordion").accordion("activate", -1); });
});
Here is what I am trying to do with this javascript code. When I mouse over the cat contents I want the accordion with cat contents to open. And when I leave it to close the accordion selection.
When I hover my mouse over the html contents cat ,rat. It should side by side open the accordion button of those contents. Example: I hovered over rat (of html contents) I should see accordion rat open (or active i.e. contents visible).
Updated (see demo)
It sounds like you want something like this: when a content section is hovered over, find the title of that section, match its text against the text of the <a> elements in the accordion, and activate that section:
$(function() {
$("#accordion").accordion();
var links = $('#accordion a').map(function() {
return $(this).text().trim().toLowerCase();
}).toArray();
$('div.content').mouseover(function() {
var title = $(this).find('div.title').text().toLowerCase();
var index = links.indexOf(title);
if (index != -1) {
$("#accordion").accordion("activate", index);
}
});
});
P.S. jQuery does have a .hover() method for this as well.
It should be as succinct as the following (with potential minor tweaks):
$('.content .title').hover(function(e){
var index = this.textContent.split(/\W/)[1] - 1;
$("#accordion").accordion('activate', index);
});
Be careful with the HTML as this regular expression is overly simple in that it just grabs the last "word" which in the case of your example is a number. We subtract one to get a zero-based index. That will break if you add further text to the element.
