#13949 closed feature (plugin)

Multiple arguments support in hasClass

Description

Sometimes, we need to check multiple class with hasClass,

if ( $el.hassClass("class1") && $el.hasClass("class2") && ...) {
  //Yes It does
}

It would be great if supports multiple classNames like

if ( $el.hasClass("class1, class2, class3") ) {
  //Yes It does
}

Actually it does support multiple classes just yet:

if ($el.hasClass("class1 class2 class3")) { Yes It does }

#13948 is a duplicate of this ticket.

hasClass doesn't support multiple classes, its behavior on input with multiple classes is unspecified:

$('<div>').addClass('a b').hasClass('a b')
true
$('<div>').addClass('a b').hasClass('b a')
false

I'm against such a change, it's not obvious if hasClass('class1 class2') is supposed to mean that element has all of those classes set or at least one of them. If you really need it, you can define a very small plugin (warning: not tested):

jQuery.fn.hasAllClasses = function( classesString ) {
    var i,
        classes = ( classesString || '' ).match( /\S+/g ) || [];
    for ( i = 0; i < classes.length; i++ ) {
        if ( !this.hasClass( classes[ i ] ) ) {
            return false;
        }
    };
    return true;
};

Resolution: plugin

This does seem like perfect plugin material to me. You can implement hasAllClasses, hasAnyClass, or whatever. You could also do it using $el.filter(".class1.class2").length > 0 or similar.

I agree that .hasClass("a b").hasClass("b a") must be true.
