javascript - JSON.parse() not working even though JSON string is valid -

i trying post form through ajax jquery. php script points returns json encoded array. but, @ receiving end on main page json.parse() not working.

please suggest if missing on file types need included

here code.

< script type = "text/javascript" >    $(document).ready(function() {      $("#send").submit(function() {        //$("#submit_form").html('');        $("#modal-text2").html("<img src=" + "img/loader1.gif "                 + "/></br</br><h4>data validation in process !!! please wait</h4>");        $("#mymodal2").modal('show');          $.post($("#send").attr("action"), $("#send").serialize(), function(data) {          var decode = json.parse(data);          if (decode.err > 0) {            alert("hi");          }        });          //important. stop normal post        return false;      });    });   < /script>

the json encoded array being sent php script is:

{"err":8,"er1":1,"er3":1,"er4":1,"er5":1,"er6":1,"er7":1,"er8":1,"er9":1,"error1":"first name required","error3":"last name required","error4":"email required","error5":"please select gender","error6":"date of birth required","error7":"mobile no required","error8":"password required","error9":"please fill captcha"} 

don't know if cause of hte problem or if typo in here, have typo in following line:

<img src="+"img/loader1.gif "+"/></br</br> 

you aren't closing first linebreak, , slash should come after br - not sure why have many quuotes in html block - should :

$("#modal-text2").html("<img src='img/loader1.gif'/><br/><br/><h4>data validation in process !!! please wait</h4>")
