Try this

$(document).ready(function(){
                $("#postme").attr("disabled","disabled");
                    $("#checky").click(function(){
                        if($("#checky").is(":checked")){
                         $("#postme").removeAttr("disabled");   
                         }
                        else{
                            $("#postme").attr("disabled","disabled");
                            }
                    });
                })
