Removing all dynamic 'data attributes' of an Element
Solution 1
YOu can use like this
var data = $("div").data();
var keys = $.map(data, function (value, key) {
return key;
});
for (i = 0; i < keys.length; i++) {
$("div").removeAttr("data-" + keys[i]);
}
Edit
Suggested by @Mottie
$.each($('div').data(), function (i) {
$("div").removeAttr("data-" + i);
});
Solution 2
You can use this code :
var data = $('div').data();
for(var i in data){
//for change
$('div').attr("data-"+i,"something");
//for remove
$("div").removeAttr("data-" + i);
}
The $('div').data();
prepare a list of all data attributes in var data
variable.
Then you can work with it.
This is fiddle of this solution.
UPDATE Suggested by @Mottie
$.each($('div').data(), function (i) {
//for change
$('div').attr("data-"+i,"something");
//for remove
$("div").removeAttr("data-" + i);
});
Solution 3
I think that the removeData()
function is what you are looking for here. This will remove all data
information stored on the element.
The .removeData() method allows us to remove values that were previously set using .data(). When called with the name of a key, .removeData() deletes that particular value; when called with no arguments, all values are removed. Removing data from jQuery's internal .data() cache does not affect any HTML5 data- attributes in a document; use .removeAttr() to remove those.
It will not however remove the actual attributes from the elements. In order to remove the actual attributes, you'll need to extract a list of the existing attributes. You could do this by inspecting the data()
function of an element (before running removeData
).
The data()
function will return an object of key => value
pairs that you can then use to remove the actual attributes from the element using removeAttr()
.

Prashant about 2 years
I have a div where dynamic data- attributes get added on some tags. (name of data- attributes to be generated dynamically by script, so there is no way my script will know the NAME of data-attribute)
<div data-1223="some data" data-209329="some data" data-dog="some value"> </div>
Now, I want to write a code in which it resets the div by removing all the data attributes and their values.
I can use
$('div').attr('data-209329',"")
but the problem is I don't know the name of data-attribute that will be added. the data-attribute that will be added is dynamic and I don't have control of it.
removing div and reinserting div is not an option. Pls help. thanks in advance

Superdrac about 10 yearsThere is a function to remove attribute in jQuery: api.jquery.com/removeattr it's more clean that ""
-
Pranav about 10 yearsHave you tried using .removeAttr()
-
Epsil0neR about 10 years@Pranav I think he wants to remove all
data-
attributes and he don't know all names. -
Superdrac about 10 yearsTake a look at this subject. stackoverflow.com/questions/2048720/… There is some functions that allow you to find all the attributes of an html tag. You just have to look at it, find the data-* attribute and remove them by removeAttr()
-
Pranav about 10 years@ Epsil0neR he can get all the data attributes using .data().
-
Prashant about 10 years@3rror404 the link that you have given is for all data- attributes whose 'name' I m aware of!
-
-
Prashant about 10 yearsThe data- attribute is dynamic....so i will not be able to remove it until and unless i have a name of the attribute. SO, removeData() will not work as it accepts NAME of data- attribute to be removed
-
Lix about 10 years@Prashant - yes. And you can extract the values using the
data()
function. -
Mottie about 10 years+1 I'm not sure who downvoted, but this method works.

Saman Gholami about 10 years@AnoopJoshi your solution likes mine but i don't know who downvote solutions...
-
Mottie about 10 yearsYou can shorten this to
$.each( $('div').data(), function(i){ $("div").removeAttr("data-" + i); });
(demo) -
Anoop Joshi P about 10 years@Mottie Thats cool. Didnt think about that initially.
-
Prashant about 10 yearsThis works. Thanks!!! only one issue... its combinining attributes eg if the attribute is data-hello-one its combining the value to helloOne (tried putting a alert for keys[i] in for in loop)
-
Mottie about 10 yearsYour code works, but it's not being up-voted as much because you are using a
for...in
loop which isn't always ideal -
Spomsoree over 3 yearsThis does not work, if there are more than one hyphen: jsfiddle.net/jr1d4s58 The problem is that .data() returns camelCase keys.

Spomsoree over 3 yearsThis is a working version, but there might by an easier way: jsfiddle.net/vgo7fL4y/1
