I am facing a problem on getting the nearest parent element attribute value using Jquery. Can anyone help me on this. My element structure is as below,
<ul class="Someclass">
<li><span id=3 class="heading"></span>
<ul>
<li>
<ul> <li><span ><button onclick= "redirect()"></button></span</li>
<ul>
</li>
</ul>
</li>
<ul>
<script type="text/javascript">
function redirect() {
alert(....)
}
</script>
In the above code when i click that element having onclick event i want to get the value as 3 in alert() which is in the element having the class heading. The above code is in for loop so it will have more code like this in a same page.
Give this Try
function redirect(elem) {
alert($(elem).closest('.Someclass > li').children('span').attr('id'))
}
Change Markup to this:
<li><span><button onclick= "redirect(this)"></button></span</li>
this will reffer to the current object in DOM
By wrapping elem in $(elem) will convert it to jQuery object then you can traverse to the closest and find span
You can also filter that span with .children('span:first')
Fiddle Example
With your current code, pass the clicked element reference to the function like
<button onclick= "redirect(this)">asdf</button>
then
function redirect(el) {
alert($(el).closest('.Someclass > li').children('span').attr('id'))
}
Demo: Fiddle
Bu a more recommended way will be is to use jQuery event handlers like
<button class="redirect">asdf</button>
then
jQuery(function($){
$('.Someclass .redirect').click(function(){
alert($(this).closest('.Someclass > li').children('span').attr('id'))
})
})
Demo: Fiddle
This should do it.
alert($(this).closest('.heading').attr('id'));
$(".someclass li").click(function(){
$(this).closet('.heading').attr('id');
})
could you pass it on as a parameter to your redirect function? You'd somehow hold that value in a variable in your loop.
I got a solution if you can change the id and class to parent li

I have the following example code:
<ul class="name_of_class" id="TEST">
<li class="foo">1</li>
<li class="boo">2</li>
<li class="goo">3</li>
<ul>
When a specific <li> is selected, the class changes to whatever the name is, plus sortUp or sortDown.
Example:
<ul class="name_of_class" id="TEST">
<li class="foo">111</li>
<li class="boo sortDown">222</li>
<li class="goo">333</li>
<ul>
I am trying to get the value of the actual text inside the <li>, but I keep getting undefined.
var li = document.getElementById('TEST');
alert($('#TEST').filter('.sort').html());
I tried using different ways but no matter what I do I can't get the actual value, which in this case should be 222.
Any idea what I am doing wrong?
You can select the li with either sortUp or sortDown by using the [attribute*="value"] selector,
The [attribute*="value"] selector is used to select elements whose
attribute value contains a specified value.
const li = document.querySelector('[class*="sort"]');
console.log(li.textContent);
li.style.background = "red";
<ul class="name_of_class" id="TEST">
<li class="foo">111</li>
<li class="boo sortDown">222</li>
<li class="goo">333</li>
<ul>
See css attribute selectors
I'm not sure what the classes have to do with your requirement to get the text of the clicked li element. Just set up a click event handler on the ul and then in the handler, check the event target to ensure it was an li, then just get the text of the event target.
document.getElementById("TEST").addEventListener("click", function(evt){
if(evt.target.nodeName==="LI"){
alert(evt.target.textContent);
}
});
<ul class="name_of_class" id="TEST">
<li class="foo">1</li>
<li class="boo">2</li>
<li class="goo">3</li>
<ul>
Maybe you can try this:
alert($('#TEST').find('li[class^='sort']').html());
You will find a li element that has a class that starts with "sort".
You can see more of this selector here.
I am working on a node.js application which generates a html page. This html page displays a list of associates built according to the data passed onto this page. A list is built something like as follows:
<ul class="notification-body" style="">
//loop for all assocaite id's passed to this page
<li class="testClass" data-associateid="<%= assocID %>">
<span>
<span class="subject">
<label class="btnClass label label-info">ClickMe!</label>
</span>
</span>
</li>
The generated html src looks something like this:
<ul class="notification-body" style="">
<li class="testClass" data-associateid="AA01">
<li class="testClass" data-associateid="AA02">
<li class="testClass" data-associateid="AA03">
I am trying to get the value of the data attribute using Jquery & I tried the following:
$(".btnClass").click(function(){
console.log($".testClass").attr("data-associateid"));
});
But this outputs'AA01'everytime i click on the btn and I am not getting the expected output in the console:
AA01
AA02
AA03
I tried the following also but it gives me undefined:
$(".btnClass").click(function(){
console.log($(this).find(".testClass").attr("data-associateid"));
});
You need to use jQuery.data().
I've created a jsFiddle to show this working.
I've closed the LI because AR.
<ul class="notification-body" style="">
<li class="testClass" data-associateid="AA01">1</li>
<li class="testClass" data-associateid="AA02">2</li>
<li class="testClass" data-associateid="AA03">3</li>
</ul>
Here's the JavaScript:
$(document).ready(function() {
$('.testClass').on('click', function(){
alert( $(this).data('associateid') );
});
});
Anytime you have an attribute that starts with data-, you can reference the string after the dash as a data container. Here, I'm calling jQuery.data() on an object (the LI) and asking for the data in the container associateID.
What you are currently doing:
$(".btnClass").click(function(){
console.log($(".testClass").attr("data-associateid"));
});
Will match the first instance of .testClass and print the data-associateid attribute. What you seem to want to do is to iterate over all .testClass and print their data-associateid values:
$(".btnClass").click(function(){
$(".testClass").each(function() {
console.log($(this).attr('data-associateid'));
});
});
Based on your updated HTML you would do this:
$(".btnClass").click(function() {
var id = $(this).parents('.testClass').attr('data-associateid');
console.log(id);
});
This will search the parents of the clicked on .btnClass to find elements with the class .testClass.
To get the data for that instance you simply need to traverse to the parent <li>.
Within an event handler, this is the element that the event occured on. Use closest() to access the parent <li>
$(".btnClass").on('click', function(){
alert( $(this).closest('li').data('associateid') );
});
Assign different classes to your li elements like this:
<ul class="notification-body" style="">
<li class="testClass1" data-associateid="AA01">test 1</li>
<li class="testClass2" data-associateid="AA02">test 2</li>
<li class="testClass3" data-associateid="AA03">test 2</li>
</ul>
Note, that I closed your li and ul tags to have valid HTML.
And then you can select an element with its own class:
console.log($(".testClass2").attr("data-associateid"));
I created a JSFiddle for you:
http://jsfiddle.net/8rLpbk5m/
I had hoped you could do it with just a find but apparently not. You have to use each to loop through all the elements.
$(".btnClass").click(function(){
$(".testClass").each(function() {
console.log($(this).attr('data-associateid'));
});
});
View it here: http://jsfiddle.net/rt677qp5/
Using .data() is more logical in this case.
$(".btnClass").click(function() {
$(".testClass").each(function() {
alert($(this).data("associateid"));
})
});

How to find Li tag which has a child tag by its Href value. By this I need to set class for that li tag.
My HTML
<div id="tabs" class="tab_wrapper">
<ul class="nav nav-tabs">
<li>Subject
</li>
<li>Contract
</li>
<li>Neighborhood
</li>
<li>Site
</li>
<li>Improvements
</li>
<li>Supplemental Data
</li>
</ul>
</div>
Css
.Active
{
color:red;
}
For example I have to set class "Active" for li tag which has href value "#tabNeighbourhood", so that li tag will be like
<li class="active">Neighborhood
</li>
Using :has() selector:
$('li:has(a[href="#tabNeighbourhood"])').addClass('active');
This will add class active to any LI containing anchor with specific href attribute.
Use .parent() :
$("ul.nav > li").removeClass("active"); // Clear all li's class attributes.
$("a[href='#tabNeighborhood']").parent().addClass("active"); // Add active to neighborhood.
$('li', '#tabs')
.filter(function() {
return !! $(this).find('a[href="#tabNeighbourhood"]').length;
})
.addClass('active');
I refer you to the official docs for explanation of the single parts.
Try Below Code
$(document).ready(function(){
$('body').find('a').each(function(){
if($(this).attr('href')=="#tabNeighbourhood"){
$(this).closest('li').addClass("Active");
}
});
});
Using your HTML structure you can use an immediate children selector >, has selector and a selector on href attribute.
Code:
$('#tabs>ul>li:has(a[href="#tabNeighbourhood"])').addClass('active');
Demo: http://jsfiddle.net/swvzot7f/
Try it by yourself. Here is an algorithm if you consider it too complex:
Search for needed <a> by attribute.
Select the parent of <a> that was found.
Add class to that parent.
Answer is pretty simple, so I do think it is much more important to show you the way of thinking instead of feeding with ready made-up solution.
EDIT
Just in case you fail I decided to add a solution too:
$( "a[href='NEEDED HREF TO SEARCH']" ).parent().addClass('active');
Another option, You can achieve by CSS alone:
a[href$='#tabNeighbourhood']
{
color:red;
}

JQuery method (using :has() selector):
$('ul li:has(a[href="#tabNeighbourhood"])').addClass('Active');

The following code (vanilla js :-) shows you how to add a class to an HTML element which ha specific href value. Just enter in the field the href value you want to search, it will add a class active, example try: #tabSubject or #tabImprovements. I hope it is what you need.
function setActive(){
var elm = document.getElementsByName('findElm')[0],
searchElm = elm.value,
targetStr = 'a[href*="' + searchElm + '"]',
target = document.querySelector(targetStr);
target.classList.add('Active');
}
.Active
{
color:red;
}
<div id="tabs" class="tab_wrapper">
<ul class="nav nav-tabs">
<li>Subject
</li>
<li>Contract
</li>
<li>Neighborhood
</li>
<li>Site
</li>
<li>Improvements
</li>
<li>Supplemental Data
</li>
</ul>
</div>
<input type="text" name="findElm" value="#tabImprovements"><br>
<input type="submit" value="Search" name="submit" onclick="setActive();">

I´m trying to target a <div> which is the next <li> of the parent <div> of the function show_projectinfo(). I've tried .next(), .closest(), etc... with no luck, any ideas?
The function is that if I click on a.more_info then the li.slider img is hidden... I don´t know if it is out of scope completely... This is a div that is repeated so I can´t just use the IDs.
markup:
<li class="info">
<a id="previous-slider"> < </a>
<span>01/15</span>
<a id="next-slider" href="javascript:void(0)"> > </a>
<a class="more_info" href="javascript:void(0)" onclick="show_projectinfo()">Info</a>
</li>
<li class="slider">
<img src="img/horizontal.jpg" alt="horizontal" width="624" height="429">
</li>
this is the script:
function show_projectinfo(){
$(this).closest('.slider img').hide();
$('.info_content').fadeIn();
}
The basic problem is that you are calling the method from onclick instead of binding it with jquery.
In the way you use it, the this refers to the window and not the element that was clicked.
function show_projectinfo(e){
e.preventDefault();
$(this).parent().next().find('img').hide();
$('.info_content').fadeIn();
}
$(function(){
$('.more_info').click(show_projectinfo);
});
and remove the onclick attribute from the html
If you have (although you shouldn't) to use the onclick attribute then pass it the this as an argument
function show_projectinfo(element){
$( element ).parent().next().find('img').hide();
$('.info_content').fadeIn();
}
and
<a class="more_info" href="javascript:void(0)" onclick="show_projectinfo(this)">Info</a>
Try:
$(this).parent().next() // parent() should be the <li> then next() will get your next <li>
$('.more_info').click(function(e){
e.preventDefault();
$(this).parent().next().find('img').hide();
$('.info_content').fadeIn();
});
Instead of .closest use .parent and .next, then select the img with .find.
Check out this jsFiddle:
$("a.more_info").bind("click", function(e){
e.preventDefault();
$(this).parent("li").next("li.slider").find("img").hide();
$('.info_content').fadeIn();
return false;
});
$('li').click( function (){
var nextLi = $(this).closest('div').next().children('li:first-child').attr('id');
console.log(nextLi);
});
Considering below markup:
<div id='div1'>
<li id='1'>1</li>
<li id='2'>2</li>
<li id='3'>3</li>
</div>
<div id='div2'>
<li id='4'>4</li>
<li id='5'>5</li>
<li id='6'>6</li>
</div>
You can see my live jsFiddle for more details.
So I've got 2 <ul> containers each with id's. Inside of them are a list of <li> elements.
The first <ul> is <ul id="coaches-list">. The second is <ul id="players-list">.
There are tags within each <li> that have an id called close (which is a link that I'm using as my selector), which will delete each <li> node once clicked. I'm trying to target each <ul> container to see where it is coming from.
My HTML is:
<!-- coaches box -->
<div class="box">
<div class="heading">
<h3 id="coaches-heading">Coaches</h3>
<a id="coaches" class="filter-align-right">clear all</a>
</div>
<ul id="coaches-list" class="list">
<li><span>Hue Jackson<a class="close"></a></span></li>
<li class="red"><span>Steve Mariuchi<a class="close"></a> </span></li>
</ul>
</div>
<!-- players box -->
<div class="box">
<div class="heading">
<h3 id="players-heading">Players</h3>
<a id="players" class="filter-align-right">clear all</a>
</div>
<ul id="players-list" class="list">
<li><span>Steve Young<a class="close"></a></span></li>
<li><span>Gary Plummer<a class="close"></a></span></li>
<li><span>Jerry Rice<a class="close"></a></span></li>
</ul>
</div>
My remove tag function in jQuery is:
function removeSingleTag() {
$(".close").click(function() {
var $currentId = $(".close").closest("ul").attr("id");
alert($currentId);
// find the closest li element and remove it
$(this).closest("li").fadeOut("normal", function() {
$(this).remove();
return;
});
});
}
Whenever I click on each specific tag, it's removing the proper one I clicked on, although when I'm alerting $currentId, if I have:
var $currentId = $(".close").closest("ul").attr("id");
It alerts 'coaches-list' when I'm clicking on a close selector in both <ul id="coaches-list" class="list"></ul> and <ul id="players-list" class="list"></ul>
If I change that to:
var $currentId = $(".close").parents("ul").attr("id");
It has the same behavior as above, but alerts 'players-list', instead.
So when using closest(), it's returning the very first <ul> id, but when using parents(), it's returning the very last <ul> id.
Anyone know what is going on with this whacky behavior?
It's expected behavior.
You should use:
var $currentId = $(this).closest("ul").attr("id");
$(this) points at the clicked .close.
$(".close") points at the first one found.
It's because you run that selector from click handler you should use this instead:
var $currentId = $(this).closest("ul").attr("id");
Try using this function to get the parent:
var $currentId = $(this).parents().first();
I've never used the .closest() function but according to jQuery what you have specified should work. Either way, try that out and tell me how it goes.
You also need to make it so that it selects the current element by using $(this)
