Question

i\'m triyng to validate a form. In this form you\'ve to choose at least one element by checkboxes, and I can\'t be sure about their quantity (it depends by elements number).

Answer 1

You can use :checked selector along with .length to find checked checkbox count:

var len = $(".roomselect:checked").length;
if(len>0){
    //more than one checkbox is checked
 }
