getJSON问题
$(document).ready(function(){
                     
                    $.getJSON("conn2.asp",function(json){
                                             
                                //var text=unescape(data);            
                                if(unescape(json["cont"])="ok")
                                {
                                box1();
                                sm();            
                                }
                                else
                                {box2();   
                                }
                                    });  
                           
                           });
老说$.getJSON这一行有错误，请教
