How can I change the code in jQuery which will be referred to the items above in the html?
Html code is as follows:
<div class="dramer">
<ul>
<li> </li>
<li> <a class="shares" href="#"> Click </a> </li>
<li> </li>
<li> </li>
</ul>
<div class="drops"> </div>
</div>
The code in jQuery:
$('a.shares').click(function (event) {
event.preventDefault();
event.stopPropagation();
$(this).next(."drops").slideToggle(400);
});
Function in jQuery is designed to show and hide div located out of the reach <li> and <ul>
How can I modify the code to hide jQuery and show div?
Target it directly
$(".drops").slideToggle(400);
If you need it to be context aware, something like this might work
$(this).closest(".dramer").find(".drops").slideToggle(400);
$ (this). next(. "drops"). slideToggle (400);
$(this).closest('.dramer').children('.drops').slideToggle(400);
How about trying
$ ('a.shares'). click (function (event) {
event.preventDefault ();
event.stopPropagation ();
$(this).parent(".dramer").children(".drops").slideToggle(400);
});
You should go up to the nearest ancestor that is shared between .shares and .drops, and then find .drops from there:
$(".shares").on("click", toggleDrops);
function toggleDrops (event) {
$(this).closest(".dramer").find(".drops").slideToggle(400);
return false;
}
I'm not sure I understand what you what. If you mean you want to hide the div which is a child of your , you can try this:
$ ('a.shares'). click (function (event) {
event.preventDefault ();
event.stopPropagation ();
$(".drops").slideToggle (400);
});

Here is my HTML?
<ul>
<li>
<a href="./link1">
<div>something</div>
<span>link</span>
</a>
</li>
</ul>
And this is my jQuery code:
$('li').on('click', function(){
var link = $(this).find('a').attr('href');
})
As you see, there is two <a> tags. And .find() refersh to both of them. While I just want to select the <a> which is right inside (one level) in the <li> tag. So expected result is ./link.
What alternative should I use instead of .find() ?
You can use the direct descendant selector.
$('li').on('click', function(){ var link = $(this).find('> a').attr('href'); })
Try with eq(0) .It will get the first a tag
Or
Do with first('a')
$(this).children().first('a').attr('href')
$('li').click(function(){
console.log($(this).children('a').eq(0).attr('href'))
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
<li>click
<a href="./link1">
<div>something</div>
<span>link</span>
</a>
</li>
</ul>
Method 1: Using Jquery's children and first
$('#myList').on('click', function() {
var link = $('#myList').children('a').first();
console.log(link.attr('href'));
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<ul>
<li id="myList">
<a href="./link1">
<div>something</div>
<span>link</span>
</a>
</li>
</ul>
Method 2: Using the immediate children selector >
$('#myList').on('click', function() {
var link = $('li > a:first');
console.log(link.attr("href"));
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<ul>
<li id="myList">
<a href="./link1">
<div>something</div>
<span>link</span>
</a>
</li>
</ul>
the first specific element
What alternative should I use instead of .find() ?
$(this).find('a:first')
seems like only logical solution and easy to read by developer
Don't do so. How is the browser meant to know which link to follow? It'd be invalid HTML
I suggest you using this instead:
startmiddleend
As you can see start and end are linked to page1 but the middle points to page2.
I am making a menu that has submenu. When I click on a menu item I am using prevent default because it is a tags, but on the submenu level I don't want to prevent default. I haven't been able to figure out how to make it work so it doesn't affect the top level.
<div id="block-menu-block-2">
<ul class="menu">
<li>
1
</li>
<li>
2
<ul class="menu">
<li>2.1</li>
<li>2.2</li>
<li>2.3</li>
<li>2.4</li>
</ul>
</li>
<li>
3
<ul class="menu">
<li>3.1</li>
<li>3.2</li>
<li>3.3</li>
<li>3.4</li>
</ul>
</li>
<li>
4
</li>
<li>
5
</li>
<li>
6
<ul class="menu">
<li>6.1</li>
</ul>
</li>
</ul>
</div>
Here is the jQuery
$('#block-menu-block-2 ul li').on("click", function() {
if ($(this).children().is('ul')) {
if ($(this).find('ul').is(':visible')) {
$(this).find('ul').hide("blind");
$(this).removeClass('menuItemSelected');
$(this).find('ul').removeClass('menuItemSelected');
} else {
$(this).parent().find('li ul').hide("blind");
$(this).parent().find('.menuItemSelected').removeClass('menuItemSelected');
$(this).find('ul').show("blind");
$(this).addClass('menuItemSelected');
$(this).find('ul').addClass('menuItemSelected');
};
event.preventDefault()
}
});
Here is a codepen for reference: http://codepen.io/mathiasha/pen/bVpMyo
Added some stuff. Changed some stuff. Couldn't paste into codepen from my phone so this might not work. Code first, then word wall.
$('#block-menu-block-2 ul li').each (function () {
var $this = $(this);
if ($this.find ('ul:first').length > 0) {
$this.click (function () {
if ($this.find ('ul:visible').length > 0) {
$this.removeClass ('menuItemSelected').find ('ul').removeClass('menuItemSelected').hide ('blind');
} else {
$this.parent ().find ('ul li').hide ('blind');
$this.parent ().find('.menuItemSelected').removeClass ('menuItemSelected');
$this.addClass ('menuItemSelected').find ('ul').show ('blind').addClass ('menuItemSelected');
}
});
}
});
$('#block-menu-block-2 > ul > li > a').click (function (e) {
if ($(this).find ('ul:first').length > 0)
e.preventDefault ();
});
The real answer lies in only putting the preventDefault only on the a tag and only when it is the immediate child of a li tag tjat is the immediate child of a ul tag that is the immediate child of the block-menu. See the last 3 lines.
The rest of the code below should only add the click listener to li tags with ul tags inside. Tried to use chaining to limit the number of jQuery objects created. Might have messed up what it was doing. You only really need to remove preventDefault from where it is and than use the last 3 lines.
Can you not add a class to your submenu triggers, e.g. .submenu-trigger, and then use the following jQuery:
$(document).on('click', function(e) {
if ($(e.target).hasClass('submenu-trigger')) e.preventDefault();
});
Ignoring all the other menu manipulation and putting the event on <a> tags you can simply check if the <a> has a sibling <ul> and if it does prevent default
$('#block-menu-block-2 a').click(function(e){
if( $(this).siblings('ul').length ){
e.preventDefault();
}
// menu manipulation code
});
I would like to show the active tab's name (text) in a span .active-class.
Example:
<ul class="tabs">
<li class="feinleinen active">feinleinen</li>
<li class="glatt">glatt</li>
</ul >
<span class="active-class">*Active_Tab_Name_Here (i.e. feinleinen) *</span>
What you want is either to have a click event each time a link is clicked and put the text in there?
Javascript:
function changeSpan(var newText){
document.getElementByClassName('active-class').innterHTML(newText);
}
When the above you need to initialise the function. this can be done in the anchor within the list item.
<li><a href='#' onclick='changeSpan("new item name!");'>
Don't forget the hash (#) within the href! This stops the default action, in layman's terms.
With jQuery this can be a bit simpler
$('a','ul.tabs>li').click(function(){//a classname would be a better selector
$('.active-class').appendTo($(this).innerHTML());//can also use $(this).text();
return false;//also stops default action
});
FIDDLE:
HTML
<ul class="tabs">
<li class="feinleinen active">feinleinen
</li>
<li class="glatt">glatt
</li>
</ul>
<span class="active-class">active tab name here</span>
SCRIPT
$('.active-class').text($('.tabs .active').find('a').text());
I guess you want this on click , therefore bit updation to my above code here :-
$('.tabs a').click(function () {
$('.tabs li').removeClass('active');
$(this).parent('li').addClass('active');
$('.active-class').text($(this).text());
});
fiddle: http://jsfiddle.net/x97g8sc7/
$(".active-class").text($(".tabs .active").text());
I have some extensive HTML element in the following (simplified) format:
<div id="firstdiv" class="container">
<ul>
<li id="4"> <a title="ID:4">Tree</a>
<ul>
<li id="005"> <a title="ID:005">Leaf Tree</a>
<ul>
<li id="10"> <a title="ID:10">Fruit Tree</a>
<ul>
<li id="0050338"> <a title="ID:0050338">Apple Tree</a>
<ul>
<li id="399"> <a title="ID:399">Green Apple Tree</a>
</li>
</ul>
</li>
</ul>
</li>
</ul>
</li>
<li id="005"> <a title="ID:005">Conifer</a>
<ul>
<li id="10"> <a title="ID:10">Pine Tree</a>
</li>
</ul>
</li>
</ul>
</li>
</ul>
</div>
I want to access the value of the title attributes of all a-tags inside the div-container with the id="firstdiv" on click.
I tried the following jQuery function but it didn't work:
$("#firstdiv").children("a").on('click', function () { /*some code here*/ });
Any ideas what I'm doing wrong?
children() only goes one deep try find()
$("#firstdiv").on('click', function () {
$(this).find('a').each(function(){
console.log($(this).attr('title'))
})
});
will get all a tags titles when the #first_div is clicked
$("#firstdiv a").on('click', function () {
console.log($(this).attr('title'))
});
will get the title of the a tag you clicked on
children() does what it says, looks at child nodes only - not descendant nodes also. For that, you need find(). However, you need neither in your case, just a change to your selector.
$('#firstdiv a')
As with CSS, a space in the selector denotes a child OR descendant.
According to the jQuery documentation
The .children() method differs from .find() in that .children() only
travels a single level down the DOM tree while .find() can traverse
down multiple levels to select descendant elements (grandchildren,
etc.) as well
So change your selector to:
$("#firstdiv").find("a").on("click", function () {});
This will search everything beneath #firstdiv in your DOM tree.
Or even:
$('#firstdiv a').click(function(){
... do stuff
});
That will select all 'a' elements within #firstdiv
Try this http://jsfiddle.net/ApfJz/22/
$("#firstdiv a").on('click', function () { alert($(this).attr('title')); });
Demo
$(document).ready(function() {
$('#firstdiv a').click(function(){
alert($(this).attr('title'))
});
});
$("#firstdiv").find("a").on('click', function () {
});
I have this kind of setup in my html
<section class="grp">
<ul class="normal">
<li>Normal Thing <button class="toggle-advanced">toggle advanced</button></li>
</ul>
<ul class="advanced">
<li>This is Advanced</li>
</ul>
</section>
<h1>Another Thing</h1>
<section class="grp">
<ul class="normal">
<li>Normal Thing <button class="toggle-advanced">toggle advanced</button></li>
</ul>
<ul class="advanced">
<li>This is Advanced</li>
</ul>
</section>
How can I toggle the "advanced" ul if I clicked the button in ul.normal?
I tried it like this in coffeescript
$('.normal').on 'click', '.toggle-advanced', (e) ->
$(#).closest('.grp').siblings('.advanced').slideToggle();
since jquery is tagged... using jquery
$('.toggle-advanced').click(function(){
$(this).parents('ul.normal').siblings('ul.advanced').toggle();
});
or
$('.toggle-advanced').click(function(){
$(this).parents('.grp').find('ul.advanced').toggle();
});
these should work unless you aree adding the content dynamically.. use on() if added dynamically
$('.normal').on('click', '.toggle-advanced', function(){
$(this).parents('.grp').find('ul.advanced').toggle();
});
.advanced is not a sibling of .grp element, it is the sibling of the parent .normal element
$(#).closest('.normal').siblings('.advanced').slideToggle();
The javascript equal will be
$('.normal').on('click', '.toggle-advanced', function(){
$(this).closest('.normal').siblings('.advanced').slideToggle();
})
you can try this
$(".toggle-advanced").on('click', function(){
$(this).closest(".normal").siblings('.advanced').slideToggle();
});
this code is jquery based
In Jquery, you can use parent and siblings functions to get to the desired element.
Try this:
$('.toggle-advanced').click(function() {
$('this').parent().siblings().toggleSomething()
});
siblings returns all the siblings for given element, which in your case will always return "advanced" ul.
This should work.
$("ul.normal>li>button").click(function () {
$(this).closest('.normal').siblings('.advanced').slideToggle();
});
