i've a question about 'this'.
With this i can get the content of actual element, but i want to get the content of previous element.
function deneme2(e){
alert(e.innerHTML);
}
Demo: http://jsfiddle.net/aldimeola1122/247m3xec/
Is there any function to get the content of child or parent element?
How can i achieve that?
Thanks in advance.
You can use previousElementSibling which gives the previous sibling element to the current element.
function deneme2(e){
alert(e.previousElementSibling.innerHTML)
}
DEMO
It isn't realy clear to me if you want the parent-element or the sibbling element. If you want the html of the parent element of e, you can use following code:
function deneme2(e){
alert(e.parentNode.innerHTML);
}
If you want the html of the child-element of e, you can use:
e.children[i].innerHTML
With i being the index of the element.
Check this:
function deneme2(e){
alert($( "#"+ e.id).prev().html());
}
Or try the post of Amit Joki. This is the same, but my post with using JQuery api.

So I know that using "a:first" will get the first link of a page. Lets assume we have the following:
<div class="masterclass">
Link 1
Link 2
</div>
<div class="masterclass">
Link 1
Link 2
</div>
Naturally I can use the following code to get the first "a" of the class "masterclass"
$('.masterclass a:first').click(function() {
alert('yayfirstlink');
});
However I do not understand how to get the first link of every "masterclass"
You need to use find() here because your selector will find all the anchor elements with in .masterclass then filter only the very first one. But when you use .find(), it will find all the .masterclass elements first then will find the first anchor element in each of them.
$('.masterclass').find('a:first').click(function() {
alert('yayfirstlink');
});
or if you are sure that the target element will be the first child of its parent then you can use :first-child
$('.masterclass a:first-child').click(function() {
alert('yayfirstlink');
});
Try this,
var oFirstAnchor = $(".masterclass a:first-child");
$(".masterclass a:first-child") is what you are looking for.
so:
$('.masterclass a:first-child').click(function() {
alert('yayfirstlink');
});
This is how u loop through each of the masterclass and get the first link of it.
i don't know what you want to do with it though so i can only provide this
$(document).ready(function(){
var fields = $('.masterclass a:first-child');
$.each(fields, function(index, val){
alert(index);
});
});
this alerts the current links array index

I would recommend using the first of type selector for this.
$('.masterclass a:first-of-type')
This way it will always select the first anchor tag in each masterclass div even if you put other things in the div later.

So, I know how to change an attribute for the same element you hover over...
$(".click2play").mouseover(function()
{
$(this).css({'visibility' : 'hidden'});
});
question Can I do the same thing but to affect another element only within the same 'click2play' div that was hovered?
maybe like?
$(".click2play").mouseover(function()
{
$(this).(#someotherdiv).css({'visibility' : 'hidden'});
});
Thanks everyone!
This code targets a div, within the current .click2play element. I believe that's what you were asking for :)
$(".click2play").mouseover(function() {
$('div.class_name', this).css({'visibility' : 'hidden'});
});
not very clear from the ques what you wanna do so ill ans for all the options i can guess of
1.if you wanna hide all the elements of class .click2Play then use
$('.click2Play').hover(function(){$('.click2play').hide()});
2.if you want to just hide the current element of all the elements having this class use
$('.click2Play').hover(function(){$(this).hide()});
3.if you wanna generalize it then you can use.selector property of the jquery object so that you would be able to use it like
$('.click2Play').hover(function(){$($(this).selector).hide()});
so now if you will change the class name from .click2Play to some other class it will work nicely and will hide all the elements of that class.
4. if you want to hide some element inside that of current element then
$('.click2Play').hover(function(){$(this).children('selector_of_child').hide()});
5.if all the elements of this class have an element inside them having some other class and you wanna hide them all then simple use each like this
$('.click2Play').hover(function(){$('.click2play').each(function(){$(this).children("selector_Of_Child").hide()})});
I would do like this:
$(".click2play").mouseover(function(){
$(this).hide();
});
But maybe it isn't what you want to do?
I suppose this :):
$(".click2play").mouseover(function(){
$(this).css({'visibility' : 'hidden'});
});
or better
$(".click2play").mouseover(function(){
$(this).hide();
});
You want to change some other div? Why would you need $(this)?
$(".click2play").mouseover(function(){
$("#someotherdiv").hide();
});
To change a single css attribute you can do:
$(".click2play").mouseover(function(){
$(this).css('visibility', 'hidden');
});
I hope it helps

I believe most of the answers didn't payed attention to the question, which asks about removing a class. Here is the answer to both questions:
$('.click2play').bind('mouseenter mouseleave', function () {
$(this).removeClass('click2play'); // This line removes the current object's class click2play
$('jQUerySelector').removeClass('click2play'); // This will remove another element's class click2play
});
I have this
<ul>
<li id="any_list">Content to be destroyed</li>
</ul>
and this link:
remove the list "#any_list"
How can I write the deleteList() function in order to the list #any_list and its content?
You can get an element's parent using the parentNode property and you can remove a child element using the removeChild method. Therefore:
function deleteList(element) {
element.parentNode.removeChild(element);
}
It's better not to pollute the markup. Give the link an id first.
remove the list "#any_list"
Then simply
$('#delete_any_list').click(function(e){
$('#any_list').remove();
e.preventDefault();
});
http://jsfiddle.net/rMPdn/1/
Try this, example above: -
$("#any_list").each(function() {
$(this).remove();
});
First, add an id to your anchor and remove any inline Javascript:
remove the list "#any_list"
[it's considered poor practice these days to ever actually put any JS code directly into the markup].
Then, in your jQuery document.ready function add this:
$('#delete_any_list').click(function(ev) {
$('#any_list').remove();
});
See http://jsfiddle.net/alnitak/MbZpV/
$(function(){
$("#delete_any_list").click(function(e){
e.preventDefault();
$("#any_list").remove();
});
});
Delete any list
I am building a block of nested divs around a specific element on the client. I am using jQuery's .wrap() initially to get the first part of the block which is working fine. But now I want to attach the ending block after the element I am wrapping and I am finding I can't attach it to anything because it is all being created at the same time. I tried using insertAfter() but I don't want it to be a sibling of the element I am wrapping, I want it to come after it's parent.
Here is my code:
$(document).ready(function() {
buildShadows('#section');
});
function buildShadows(element){
$(element).wrap("<div class='section_shadow_wrapper'><div class='section_shadow_curve'><div class='section_shadow_outer'><div class='section_shadow_inner_left'><div class='section_shadow_inner_right'>");
$("<div class='section_shadow_bottom_left'><div class='section_test_bottom_right'>").insertAfter(element);
}
What I am trying to do is append the first element of the second part (section_shadow_bottom_left) as a sibling of 'section_shadow_inner_right' but after 'element'
Any help would be appreciated.
Thanks.
You should be able to just traverse up to the new parent you just created.
Have you tried this?
function buildShadows(element){
$(element).wrap('<div class="section_shadow_wrapper clearfix"><div class="section_shadow_curve"><div class="section_shadow_outer"><div class="section_shadow_inner_left"><div class="section_shadow_inner_right">')
.parent().after('<div class="section_shadow_bottom_left"><div class="section_test_bottom_right">');
}
Try traversing to the next sibling of the original element and using .insertBefore() on it.
var nextsibling = $(element).next();
//Wrap code
$("<div class='section_shadow_bottom_left'><div class='section_test_bottom_right'>").insertBefore(nextsibling);
I have a div <div id="masterdiv"> which has several child <div>s.
Example:
<div id="masterdiv">
<div id="childdiv1" />
<div id="childdiv2" />
<div id="childdiv3" />
</div>
How to clear the contents of all child <div>s inside the master <div> using jQuery?
jQuery's empty() function does just that:
$('#masterdiv').empty();
clears the master div.
$('#masterdiv div').empty();
clears all the child divs, but leaves the master intact.
jQuery('#masterdiv div').html('');
Use jQuery's CSS selector syntax to select all div elements inside the element with id masterdiv. Then call empty() to clear the contents.
$('#masterdiv div').empty();
Using text('') or html('') will cause some string parsing to take place, which generally is a bad idea when working with the DOM. Try and use DOM manipulation methods that do not involve string representations of DOM objects wherever possible.
I know this is a jQuery related question, but I believe someone might get here expecting a pure Javascript solution. So, if you were trying to do this using js, you could use the innerHTML property and set it to an empty string.
document.getElementById('masterdiv').innerHTML = '';
jQuery recommend you use ".empty()",".remove()",".detach()"
if you needed delete all element in element, use this code :
$('#target_id').empty();
if you needed delete all element, Use this code:
$('#target_id').remove();
i and jQuery group not recommend for use SET FUNCTION like .html() .attr() .text() , what is that? it's IF YOU WANT TO SET ANYTHING YOU NEED
ref :https://learn.jquery.com/using-jquery-core/manipulating-elements/
If all the divs inside that masterdiv needs to be cleared, it this.
$('#masterdiv div').html('');
else, you need to iterate on all the div children of #masterdiv, and check if the id starts with childdiv.
$('#masterdiv div').each(
function(element){
if(element.attr('id').substr(0, 8) == "childdiv")
{
element.html('');
}
}
);
The better way is :
$( ".masterdiv" ).empty();
$("#masterdiv div").text("");
$("#masterdiv > *").text("")
or
$("#masterdiv").children().text("")
$('#div_id').empty();
or
$('.div_class').empty();
Works Fine to remove contents inside a div
You can use .empty() function to clear all the child elements
$(document).ready(function () {
$("#button").click(function () {
//only the content inside of the element will be deleted
$("#masterdiv").empty();
});
});
To see the comparison between jquery .empty(), .hide(), .remove() and .detach() follow here http://www.voidtricks.com/jquery-empty-hide-remove-detach/
When you are appending data into div by id using any service or database, first try it empty, like this:
var json = jsonParse(data.d);
$('#divname').empty();
$("#masterdiv div[id^='childdiv']").each(function(el){$(el).empty();});
or
$("#masterdiv").find("div[id^='childdiv']").each(function(el){$(el).empty();});
try them if it help.
$('.div_parent .div_child').empty();
$('#div_parent #div_child').empty();
