.removeAttr()
.removeAttr( attributeName ) Returns: jQuery
Description: Remove an attribute from each element in the set of matched elements.
-
version added: 1.0.removeAttr( attributeName )
attributeNameAn attribute to remove; as of version 1.7, it can be a space-separated list of attributes.
The .removeAttr() method uses the JavaScript removeAttribute() function, but it has the advantage of being able to be called directly on a jQuery object and it accounts for different attribute naming across browsers.
Note: Removing an inline onclick event handler using .removeAttr() doesn't achieve the desired effect in Internet Explorer 6, 7, or 8. To avoid potential problems, use .prop() instead:
$element.prop("onclick", null);
console.log("onclick property: ", $element[0].onclick);
Example:
Clicking the button enables the input next to it.
