javascript - Multiple classes in one jquery initialization -

i'm using plugin

http://www.jqueryscript.net/layout/responsive-equal-height-plugin-with-jquery-responsibleheight.html

but don't know how make "child" multiple classes.

here's code initialize plugin. here used plugin? copy , paste code , put different class under "child" bit redundant. there way can lessen code without using same code on , on again?

thanks!

//initialise plugin     $('.item-container div').responsibleheight({       delay:    0,       child:    '.filter',       widths:   [         [1300, 10],         [1000, 8],         [700, 4],         [40, 2],         [0, 1]       ]     });      //destroy plugin, remove heights , stop working on resize     $('.destroy').click(function(){       $('.item-container div').responsibleheight('destroy')     });      //reinitialise plugin     $('.reinit').click(function(){       $('.item-container div').responsibleheight('reinit')     }); 

do want select items multiple classes or multiple items various classes ?

if code looks this:

child:    '.filter', 

---

// may not work - plugin allows select 1 child

if want select childs 1 of few classes, code this: (simply separate classes using comma)

child:    '.filter, .class2, .class3', 

---

or if want select items have more 1 class: (list classes 1 after another)

child:    '.filter.class2.class3', 

---

hope :)
