I have different types of tag which have "rel" property using jQuery or javascript.
<a rel="popup10">test</a>
<div>text2</div>
<p rel="popup20">text3</p>
<span rel="other">test4</span>
I want list of all element which have rel property with value like "popup", ignore number 10 or 20 whatever. i don't want span tag because it has rel property but value is not popup.
You need to use attributes selector. You can select all element as your requirement like this:
$('*[rel^="popup"]')
try like this:
$('*[rel^="popup"]').each(function(){
alert($(this).text());
//do what ever you want
})
demo
Use the following, example I want all the div have ID only, then
<div id='test1'>aaaa</div>
<div id='test2'>bbbb</div>
<div id='test3'>cccc</div>
<div>No ID!</div>
JQuery
$(document).ready(function () {
$("div[id]").each(function () {
alert(this.id);
});
});
Please see the JSFiddle

I need a little help with removing the href element of the below 'a' element:
<div class="carousel__tape-item js-product">
<div class="sale-content__cell">
</div>
</div>
This is my attempt but it doesn't work:
var a = $(".carousel__tape-item .sale-content__cell");
a.find("a").removeAttr("href");
Any ideas?
You want to use the multiple selector syntax for jquery
$(document).ready(function() {
$('.carousel__tape-item.js-product').find('a').removeAttr('href');
});

I gave my link a an id where if I click the link, I want my javascript to adjust the background image. I made a js-fiddle of a simple version of what I want here:
https://jsfiddle.net/qp8d390b/
<body background="http://www.blueskiescareers.co.uk/wp-content/uploads/2014/05/blue-sky-clouds.jpg">
<li>
<a id = "attempt1" href="#top">SNOOPY1</a>
</li>
<li>
<a>SNOOPY2</a>
</li>
<li>
<a>SNOOPY2</a>
</li>
<div id= "#top">TOP PART </div>
</body>
$(document).ready(function() {
$("a[id='attempt1']").click(function(e) {
e.preventDefault();
alert('works');
document.body.background = "https://upload.wikimedia.org/wikipedia/commons/0/02/Fried_egg,_sunny_side_up.jpg";
});
});
I'm new to selecting with javascript. Any help would be appreciated!
try to use $("#attempt1")
use # to get any id in html
Firstly your HTML is invalid; li must be in either a ul or ol and all a elements must have either a name or href attribute.
Secondly, jQuery uses CSS rules, so to select by id is $('#attempt1').
Lastly, to change the background CSS property to an image the URL string should be wrapped in url(). Try this:
$(document).ready(function() {
$("#attempt1").click(function(e) {
e.preventDefault();
$('body').css('background', 'url("https://upload.wikimedia.org/wikipedia/commons/0/02/Fried_egg,_sunny_side_up.jpg")');
});
});
You can select it with :
$('#attempt1')
You should use id-selector in this case
https://api.jquery.com/id-selector/
$("#attempt1")
The selector you used which is attribute selector is more used in inputs than in links (a elements)
https://api.jquery.com/attribute-equals-selector/
You can find more info on jQuery selectors in
https://api.jquery.com/category/selectors/

How to add text from span tag to data-attr?
Example:
I have this code
<div class="clearfix colelem" id="u92-5"><!-- content -->
<p>Icon<span id="u92-2">iconsymbol</span></p>
</div>
And I want to add iconsymbol to data-attr="iconsymbol" of the same element like a:
<div class="clearfix colelem" id="u92-5" data-attr="iconsymbol"><!-- content -->
<p>Icon<span id="u92-2">iconsymbol</span></p>
</div>
Yes and it will be with all elements which has a title="icon"
<script>
$( document ).ready(function() {
$("[title*='icon']").attr('data-attr',function(){
// I don't know
}).removeAttr('title');
});
</script>
Do you know how to do it?
So I know it is very simple but I am new in jquery and I need in your help.
I hope you understood my question.
Here is an example that should work for you. There is probably a few ways you can pull this off, but this should hopefully get you started. Please see the attached JSFiddle to see this example in action
$(function() {
$('[title*="icon"] span').each(function(){
$(this).parent().closest('div').attr('data-attr', $(this).text())
});
});
Here is another way you can do this as well
$('[title*="icon"]').each(function(){
$(this).attr('data-attr', $(this).children().closest('span').text());
});
JSFiddle Example
Your <div>s should have attribute title="icon"
You are using a callback to attr() function, so return the value which you need to set inside the function using .text().
$(document).ready(function () {
$("[title='icon']").attr('data-attr', function () {
return $(this).find('span').text();
}).removeAttr('title');
});

I have some question about how to get some value from some element like div,etc using jquery and without write onclick event or etc on the div where I want to get that value.
Here is my code:
<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
</head>
<body>
<div id="test" title="test1">test</div>
<div id="test2" title="test2">test2</div>
<script>
function getVal(attr,value){
$("#show").text("this "+attr+" have value ="+value);
}
$(document).ready(function(){
$("#test").click(function(){
getVal("#test",$("#test").attr("title"));
});
});
</script>
<div id="show"></div>
</body>
</html>
Usually to get some value from div that i click, I add an onclick event on div like
<div id='test' onclick="getVal(test)" ></div>
and it will return "test". And the code that I write above nearly what I want, but the problem that I have is if I have a many div, how can I get the value from each div that I click just using jquery click function and I don't need to write
$("#test").click(function(){
getVal("#test",$("#test").attr("title"));
});
$("#test2").click(function(){
getVal("#test2",$("#test2").attr("title"));
});//and so on
here the code that I use to achieve what I want, using onclick event that I put on div:
<script type="text/javascript">
function overlay(rel){
var value = rel;
$(document).ready(function(){
$(".img"+value).click(function(){
$(".overlay-bg"+value).fadeIn();
});
$(".close"+value).click(function(){
$(".overlay-bg"+value).fadeOut();
})
});
}
</script>
<div id="gallery">
<img src="http://localhost/wedding/source/gallery/thumb/thumb-a.jpg" class="img1" onclick="overlay(1)" title="photo1" alt="photo1"/>
</div>
<div id="overlay-bg" class="overlay-bg1">
<div id="overlay"><img src="http://localhost/wedding/source/gallery/a.jpg"/>
<span>photo1</span>
<span style="font-size:0.8em;"><p>photo a</p></span>
<div id="close" class="close1"></div>
</div>
</div>
<div id="gallery">
<img src="http://localhost/wedding/source/gallery/thumb/thumb-b.jpg" class="img2" onclick="overlay(2)" title="photo2" alt="photo2"/>
</div>
<div id="overlay-bg" class="overlay-bg2">
<div id="overlay"><img src="http://localhost/wedding/source/gallery/b.jpg"/>
<span>photo2</span>
<span style="font-size:0.8em;"><p>photo b</p></span>
<div id="close" class="close2"></div>
</div>
</div>
I'm really want to know how to resolve my problem.
Give the elements you want to attach the click event handler to the same class. Then use the class selector [docs] to select all of them:
$('.sharedClass').click(function() {
getVal(this.id, $(this).attr("title"));
});
jQuery will bind the event handler to each of the selected elements.
There are many ways to select elements [docs], selection by ID or class are just two of them. You might also find the jQuery tutorial useful to get a better idea of how jQuery works.
you can use the this keyword within the handler function, and it will point to the element that was clicked
Here's the correct way to do it.
Put a class name to your target div e.g.
<div id="test" class="clickable" title="test">test</div>
<div id="test2" class="clickable" title="test">test</div>
...
...
Then create a jQuery event with selected class
$('.clickable').click(function(){ ... });
<div id="test">harsh</div>
<script>
alert(document.getElementById('test').innerHTML);
</script>
If you want to call this function with the click of every div, use :
$("div").click(function(){
getVal($(this),$(this).attr("title"));
});
If you want to call the function for a set of divs, but not all, give those divs a class name as suggested by #Felix Kling.
Check out the jQuery Selectors to get a better idea.
Not sure what you're trying to achieve.
If you have multiple values how do you want to store them?
If you have an array that you wanted to populate you can use the each() function on a JQuery selector to traverse all elements selected.
Like so:
var values = new Array();
$(document).ready(function(){
$('#test1, #test2').each(function(){
values.push($(this).html());
});
});
You could also store the values in an associative way to make retrieval a bit easier if you didn't want to iterate through an array. For example you could use the value of the 'title' attribute as the key in the array.
Replace the values.push() line with this line of code:
values[$(this).attr('title')] = $(this).html();
Hello I have the following code:
Javascript/jQuery:
$(document).ready(function() {
$(".clickMe").click(function() {
$(".textBox").toggle();
});
});
Html code printed with a for loop:
<a class="clickMe">Toggle my text</a>
<br />
<div class="textBox"> - This text will be toggled</div>
<a class="clickMe">Toggle my text</a>
<br />
<div class="textBox"> - This text will be toggled 2</div>
<a class="clickMe">Toggle my text</a>
<br />
<div class="textBox"> - This text will be toggled 3</div>
I would like to be able:
When the page loads I want the to be hidden and toggle on click.
Using the same ids for <a class="clickMe"> and <div class="textBox"> to be able to toggle or hide the correct/equivalent <div> element.
jsFiddle code:
http://jsfiddle.net/A7Sm4/3/
Thanks
Edit 1: Class instead of Id
Edit 2: Fixed jsfiddle link
id are supposed to be unique
you should use class to do this
[EDIT] updated the jsfiddle to fit Marko Dumic's solution: http://jsfiddle.net/SugvH/
Something like this should do the trick:
$(document).ready(function() {
var divs = [];
$(".textBox").each(function(index) {
divs[index] = this;
});
$(".clickMe").each(function(index) {
$(this).click(function() {
$(divs[index]).toggle();
});
});
});
ID must (as per spec) be unique on the page. You can easily rewrite this to use class attribute:
<a class="clickMe">Toggle my text</a>
<br />
<div class="textBox"> - This text will be toggled</div>
<a class="clickMe">Toggle my text</a>
<br />
<div class="textBox"> - This text will be toggled 2</div>
...
Initially, you need to either hide div.textBox when DOM becomes ready, or hide it using CSS.
Then you attach click handlers to a.clickMe:
$(function () {
$('a.clickMe').click(function () {
// find first of following DIV siblings
// with class "textBox" and toggle it
$(this).nextAll('div.textBox:first').toggle();
});
});
However, maybe you don't control the markup but desperately need this done, you can keep your markup as it is and still make it work due to the fact that jQuery uses Sizzle framework to query the DOM which can be forced around the limitation of document.getElementById() (which returns only one element).
E.g. suppose you used id instead of class, if you write $('#clickMe'), you'll get the jQuery collection of only one element (jQuery internally used .getElementById() to find the element), but if you write $('#clickMe'), you get the collection of all elements with the id set to "clickMe". This is because jQuery used document.getElementsByTagName('a') to find all anchors and then filtered-out the elements (by iterating and testing every element) whose attribute value is not "clickMe".
In that case (you used your original markup), this code will work:
$(function () {
$('a#clickMe').click(function () {
$(this).nextAll('div#textBox:first').toggle();
});
});
Again, don't do this unless you absolutely need to!
$(document).ready(function() {
$("a").click(function() {
$(this).parent().find("div").toggle();
});
});
Use something similar to this.
Try appending an index to each pair of a/div's ids (clickme1 and textbox1, etc). Then when an a is clicked, read the id, take the index off the end, and show/hide the textbox with the same index.
