Use jQuery .click() function with an individual element - javascript

I want to show the list of tags on an Tumblr blog only when the user clicks on the tags button. For that I use this HTML and jQuery.
HTML
<span class="tags-link">Tags</span>
<ul class="tags">
<li> {Tag} </li>
</ul>
jQuery
$(document).ready(function(){
$(".tags-link").click(function() {
$(".tags").slideDown(700, function(){
//end animation
});
});
});
Every time I click on the .tags-link every .tagsshows up on the page, and I only want the ones of the post where the user has clicked to be shown. I recently started learning jQuery and I'm a little lost here...

You can use .next() http://api.jquery.com/next/
$(this).next(".tags").slideDown(700, function(){

You need to target the tags that is the next adjacent element only:
$(document).ready(function(){
$(".tags-link").click(function() {
$(this).next(".tags").slideDown(700, function(){
//end animation
});
});
});

You can set a data attribute on both the span with class "tags-link" and the ul with class "tags". Then when you click the ".tags-link" element, it will show the ".tags" element with the same data attribute.
For example:
HTML
<span class="tags-link" data-id="1">Tags</span>
<ul class="tags" data-id="1">
<li> {Tag} </li>
</ul>
jQuery
$(document).ready(function(){
$(".tags-link").click(function() {
var id = $(this).attr('data-id');
$(".tags[data-id='" + id + "']").slideDown(700, function(){
//end animation
});
});
});

jQuery li element select by ID

can anyone please help?
I have a HTML code like this.
<ul class="nav navbar-nav navbar-left">
<li>
<img src="img/topbararrowback.png" alt="">
</li>
<li id="hide_filter">
Hide Filter
</li>
</ul>
I try to add a .click event on li having id hide_filter.
What I have done is-
$("#hide_filter").click(function()
{
alert('message');
});
And -
$(".navbar-left li").click(function() {
alert(this.id); // id of clicked li by directly accessing DOMElement property
alert($(this).attr('id')); // jQuery's .attr() method, same but more verbose
alert($(this).html()); // gets innerHTML of clicked li
alert($(this).text()); // gets text contents of clicked li
});
And -
$('ul.selectedItems li#hide_filter').click(function()
{
//$("p").hide();
alert('message');
});
And -
$('#hide_filter')[0].click(function()
{
//$("p").hide();
alert('message');
});
But nothing works for me.
Thanks in advance for helping..
Actually It works :)
$("#hide_filter").click(function()
{
alert('message');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<ul class="nav navbar-nav navbar-left">
<li>
<img src="img/topbararrowback.png" alt="">
</li>
<li id="hide_filter">
Hide Filter
</li>
</ul>
Assuming you have added the jquery library, You need to attach the event when DOM is loaded.i.e. on DOM ready event:
$(function(){//document ready function
$("#hide_filter").click(function(){
alert('message');
});
});
Working Demo
Maybe your code is not eval.
Try put your code in body tag with function wrap like this
$(function(){ //document ready function
$("#hide_filter").on("click",function(){
console.log('message');
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
Remove .selectedItems selector from your 3rd option
$('ul li#hide_filter').click(function()
{
//$("p").hide();
alert('message');
});
Remove index 0 from your 4th option
$('#hide_filter').click(function()
{
//$("p").hide();
alert('message');
});
Otherwise your 4 options are correct and will work fine. Kindly make sure you have written these codes inside ready event.
$(document).ready(function(){
$("#hide_filter").click(function()
{
alert('message');
});
});
Maybe there is a problem with jquery libraries. Are they in conflict with other javascripts?

How to Remove a Class from a Sibling of a Parent

I'm working with the off-canvas script from Foundation and it isn't working out of the box (of course) when I try to use the submenu options. I realized it wasn't adding a class (move-right) to the ul's of the li's in the off-canvas navigation. So I wrote a script to add that class which can be found here:
jQuery(document).ready(function() {
jQuery('ul.off-canvas-list li a').click(function() {
jQuery('ul.off-canvas-list li ul.left-submenu').addClass('move-right');
});
});
And here is how my HTML is structured:
<ul class="off-canvas-list">
<li class="has-submenu">Name 1
<ul class="left-submenu">
<li class="back">Back</li>
<li><a href="#"></li>
<li><a href="#"></li>
</ul>
</li>
<li class="has-submenu">Name 2
<ul class="left-submenu">
<li class="back">Back</li>
<li><a href="#"></li>
<li><a href="#"></li>
</ul>
</li>
<li class="has-submenu">Name 3
<ul class="left-submenu">
<li class="back">Back</li>
<li><a href="#"></li>
<li><a href="#"></li>
</ul>
</li>
...etc
</ul>
My problem is that my script is adding the class to ALL ul.left-submenu's instead of just the one directly under the li that I click on. I can't figure out how to add the class 'move-right' to only the 'ul.left-submenu' child of the parents li that I clicked on and remove the 'move-right' class from the other 'ul.left-submenu'
I thought maybe using the sibling() selector, but I wasn't quite sure how to implement that into my script. Any and all help is greatly appreciated.
Another issue has arose and that is being able to close the opened "ul.left-submenu" by clicking on the "Back" which comes before the other li's in each ul.left-submenu. I updated the HTML above to include the "" and also have provided the script below that I tried using that hasn't worked.
jQuery('li.back').on('click', function() {
console.log('close submenu');
jQuery('ul.left-submenu').removeClass('move-right');
});
The target element is the grandparent of the clicked element so you can use the closest method:
$('ul.off-canvas-list li a').click(function() {
$('.move-right').removeClass('move-right');
$(this).closest('ul.left-submenu').addClass('move-right');
});
you can add it directly to the clicked element by using this
jQuery(document).ready(function() {
jQuery('.left-submenu li a').click(function() {
jQuery('.left-submenu').removeClass('move-right'); // remove class move-right from every elements with class left-submenu
jQuery(this).parents('.left-submenu').addClass('move-right'); // add class move-right to the parent with class left-submenu of current element
});
});
Edit:
if in your updated code, you want to click only by a right after .has-submenu, you need this probably, so it didn't trigger on click for a inside .left-submenu
jQuery(document).ready(function() {
jQuery('.has-submenu > a').click(function() {
jQuery('.left-submenu').removeClass('move-right'); // remove class move-right from every elements with class left-submenu
jQuery(this).children('.left-submenu').addClass('move-right'); // add class move-right to the children with class left-submenu of current element
});
});
sorry for my mistakes not looking again for the code before posting it, because ul.left-submenu is in the same position with a and not it's children, you need to use .siblings to get ul.left-submenu, so change the code to this
jQuery(document).ready(function() {
jQuery('.has-submenu > a').click(function() {
jQuery('.left-submenu').removeClass('move-right');
jQuery(this).siblings('.left-submenu').addClass('move-right');
});
});
here's the working Example in Fiddle
Ok, so you want to add a class move-right to the ul.left-submenu that is directly under the has-submenu li that you clicked, right?
So:
$(document).ready(function() {
//Trigger the click only on the li's has-submenu
$('li.has-submenu').on('click', function() {
//Remove the class from other ul, if there's any
$('ul.left-submenu').removeClass('move-right');
//Finds the direct ul child using the '>' selector, and adds the class.
$(this).find('> ul.left-submenu').addClass('move-right');
});
});
The way you have your selector it targets all the ul.left-submenu elements you have, another way to target just the element clicked would be like this:
$('.off-canvas-list').on('click', 'ul.off-canvas-list li a', function (){
$('.move-right').removeClass('move-right');
$(event.target).closest('ul.left-submenu').addClass('move-right');
});
Your selector is too broad. If what you want to do is to add move-right to left-submenu when you click has-submenu, that's what you need to do:
$('.has-submenu').click(function() {
$(this).find($('.left-submenu')).addClass('move-right');
});
Fiddle: http://jsfiddle.net/x9zcav0p/
If you need to reset move-right, do this:
$('.has-submenu').click(function() {
$('.move-right').removeClass('move-right');
$(this).find($('.left-submenu')).addClass('move-right');
});
Fiddle: http://jsfiddle.net/x9zcav0p/1/
Updated markup:
For your updated markup, you can target the next() element after the anchor tag:
$('.has-submenu > a').on('click', function() {
$('.move-right').removeClass('move-right');
$(this).next().addClass('move-right');
});

How to show div by dynamic id?

I've got the follow code
<ul>
<li>Google</li>
<li>Facebook</li>
</ul>
<!- hidden divs ->
<div id="1" style="display:none;">Email</div>
<div id="2" style="display:none;"">Social Network</div>
I tried the following code but when I click on a link i would like it to show a div based on the id of the link but it is not working
<script type="text/javascript">
$(document).ready(function()
{
$(".chooserClass").click(function() {
var show = $(this).attr('id');
$(show).show();
});
});
</script>
Change
var show = $(this).attr('id');
$(show).show();
to
var show = $(this).attr('id');
$('#'+ show).show();
You have 2 elements on your page that have th same id, and they are numeric which from experience can cause all kinds of undesired behavior.
The way you want to this is like so:
<ul>
<li>Google</li>
<li>Facebook</li>
</ul>
<!- hidden divs ->
<div id="element1" style="display:none;">Email</div>
<div id="element2" style="display:none;">Social Network</div>
We use a data-show element to store the value of the id of the element that we want to display, in the javascript we can now do this:
<script type="text/javascript">
$(document).ready(function()
{
$(".chooserClass").click(function() {
var show = $(this).data('show');
$('#' + show).show();
});
});
</script>
also note that I am added in the # (for id) in front of the variable when calling the show()
Fiddle demo: http://jsfiddle.net/5U8sW/
Well, here's a quick an dirty answer:
The problem is that you can't have duplicate id's on DOM elements. They should be unique. You can use a data- property to do what you are wanting.
http://jsfiddle.net/725XT/
<ul>
<li>Google</li>
<li>Facebook</li>
</ul>
<!- hidden divs ->
<div id="1" style="display:none;">Email</div>
<div id="2" style="display:none;">Social Network</div>
And your Javascript:
$(document).ready(function()
{
$(".chooserClass").click(function() {
var show = $(this).data('div-id');
console.log(show);
$('#' + show).show();
});
});
When using javascript or jQuery to search for elements with the same IDs, only the first element is picked. I suggest you rename the IDs of the elements to be shown. Take the code below for example.
HTML
<ul>
<li>Google</li>
<li>Facebook</li>
</ul>
<!- hidden divs ->
<div id="d_1" style="display:none;">Email</div>
<div id="d_2" style="display:none;"">Social Network</div>
jQuery
<script type="text/javascript">
$(document).ready(function()
{
$(".chooserClass").click(function() {
var id = $(this).attr('id');
$('#d_'+id).show();
});
});
</script>
jsFiddle
First of all, your IDs should be unique. Thus, the <div> and the <a> must not share the similar ID names. Additionally, AFAIK, in HTML4.1 IDs starting with digits are prohibited(?)
Try the sample I coded above. Since you are using anchors, referencing the 'href' attribute would be more semantically correct.
Cheers!

js 'toggle' or 'hover' function?

I don't want to use the toggle, what would I need to use to get the following nav structure to stay put when main link is hovered over?
Current js:
<script type="text/javascript">
$(document).ready(function(){
$(".downservices").hover(function(){
$(".servicesdropped").toggle("fast");
});
});
</script>
Sample page
(Notice that when the submenu pops up, I cannot click on the links, as the submenu fades away)
If you aren't fussed about animation, and you wish to use JQuery you can toggle the CSS visibility rule on the class.
$(document).ready(function()
// Make sure the item is hidden initially, best to do
// this in CSS.
$(".servicesdropped").css("visibility", "hidden");
{
$(".downservices").hover(function()
{
$(".servicesdropped").css("visibility", "display");
},
function()
{
$(".servicesdropped").css("visibility", "hidden");
});
});
Using visiblity means the element will still consume the space it does in the DOM but does not display making sure the structure and positioning of other elements surrounding it are left in tact. The downside is that animations such as fadeIn() and fadeOut() will not work.
Your html markup architecture of menu should like this:
<ul>
<li class="downservices">GUYS
<div class="servicesdropped" style="display: none;">
<ul class="middle">
<h3>Shirts & Tanks:</h3>
<li>MuSkull</li>
<li>Bamboo Athletic Tank</li>
<li>Thin Strap Tank</li>
</ul>
<ul class="right">
<h3>Other Stuff:</h3>
<li>Shorties</li>
<li>Hoodies</li>
<li>Socks</li>
<li>Hats</li>
</ul>
</div>
</li>
<li>products</li>
<li>portfolio</li>
<li>contact</li>
</ul>
And in the script use this:
$(document).ready(function(){
$("li.downservices").hover(function()
{
$(this).find(".servicesdropped").slideDown("fast");
},
function()
{
$(this).find(".servicesdropped").slideUp("fast");
});
});
use like this
<script type="text/javascript">
$(document).ready(function(){
$(".downservices").hover(function(){
$(".servicesdropped").slideDown();
});
});
</script>
for hover out the menu disappear use this
<script type="text/javascript">
$(document).ready(function(){
$(".downservices").hover(
function(){
$(".servicesdropped").slideDown();
},
function(){
$(".servicesdropped").slideUp();
}
);
});
</script>

Show and hide <div>s with jQuery event

There are several advanced jQuery plugins which filter <div>s by corresponding id or class. This is indeed based on a simple jQuery idea, but I am not sure how to implement it. Consider a menu to show/hide the content as
<ul id="filters" class="menu" indicator="filter">
<li>All</li>
<li>First</li>
<li>Third</li>
</ul>
and we want to control the display of contents:
<div class="box first">Something</div>
<div class="box first third">Something</div>
<div class="box third">Something</div>
What is the simplest jQuery Javascript code to do so?
By default, all <div>s are shown, when we click on a <li> from menu (e.g. FIRST), jQuery will filter the <div>s to only show <div>s in which the class is "first".
Don't use attribute "indicator" as it doesn't exist. Use the class element as below. Also the A elements are not needed.
<ul id="filters" class="menu">
<li class="selected all">All</li>
<li class="first">First</li>
<li class="third">Third</li>
</ul>
Then your script
// hide all divs
$('div.box').css('display','hidden');
// add click handler on control list
$('ul#filters li').click(function() {
var classList =$(this).attr('class').split(/\s+/);
$.each( classList, function(index, item){
if (item != 'selected') {
$('div.'+item).css('display','block');
}
});
});
$(function(){
$('#filters li a').live('click', function(){
$('.box').hide();
indirector = $(this).attr('indicator');
indirector = indirector.substring(1);
if(indirector == '')
$('.box').show();
else
$('div.' + indirector).show();
});
});
Reference
Use the class attribute instead of indicator and try the following:
$('#filters li').click(function(){
$('div.' + $(this).attr('class')).show();
});
for this to work you would have to assign an all class to your first LI as well as all of your DIVs. Hope this helps!
try this code,
$('#filters li').click(function(){
$("div.box").hide();
$('div.box' + $(this).children('a').attr('indicator')).show();
});
