Submit form only if at least one checkbox is checked

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

i suggest you to use "button" instead of "submit".

please follow this

HTML->

$(function(){

$("#submit").click(function(e){

    var number_of_checked_checkbox= $("input[name=q]:checked").length;
    if(number_of_checked_checkbox==0){
        alert("select any one");
    }else{
        $("#booking").submit();
    }

         });
    });
