- ELEMENTDOM ElementstringDOM Element Array
The element(s) with the class to remove. Can be a single DOM element, an element ID specified as a string, or an array of DOM Element objects. If specifying the ID as a string, the ID corresponds to the value for the id HTML attribute for the element you wish to assign a style.
The class to remove from the element(s).
The $rcn() function removes the class name from the passed-in element(s). This will only remove the specified class name. You might want to use this to remove some temporary styling to an element, such as a focus, or error style. This function is typically used after the $acn() function has been used to add a class name to an element.
/*Assume that you previously added the 'inputError' class name to an element to indicate that a validation error had occurred. Now, assume that the user has corrected the error and you want to remove the 'inputError' class name from the element. */ $rcn('firstname','inputError'); /*Remove a class name from multiple elements.*/ $rcn(['firstname','lastname','address','city','state','zip'],'inputError');
