.removeAttr()


.removeAttr( attributeName )Returns: jQuery

Description: Remove an attribute from each element in the set of matched elements.

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 changes the title of the input next to it. Move the mouse pointer over the text input to see the effect of adding and removing the title attribute.
