$(document).ready(function(){   $('input[type="radio"]').click(function(){     if($(this).attr("value")=="auth_fm_chk"){         $(".sggn_in").show();         $(".gst_chk").hide();     }      if($(this).attr("value")=="cnt_as_guest"){         $(".sggn_in").hide();         $(".gst_chk").show();     } }); $("form#mychkform").submit(function(event) { event.preventdefault(); validate();   });  function validate(){    $('#cntgyes').click(function(){        function checkemail(){     var email = $("#email").val();     if((email.length < 6) ||      (email.indexof('@',0) < 1) ||      (email.lastindexof('@') != email.indexof('@',0)) ||      (email.lastindexof('@') > (email.length - 5)) ||      (email.lastindexof('.') > (email.length - 3)) ||      (email.lastindexof('.') < (email.length - 4)) ||      (email.indexof('..',0) > -1) ||      (email.indexof('@.',0) > -1) ||      (email.indexof('.@',0) > -1) ||      (email.indexof(',',0) > -1)){          $("#email").css("border-color","#f05f68");         return false;     }     else{         $("#email").css("border-color","#0c9");         return true;     }    }  if(!checkemail()){     return false;        }     else{         var email = $("#email").val();         var datastring = 'email=' + email;         $("#loading").show();         $.ajax({           url: "includes_fm/form_submi/checkou_guauth",           type: "post",           data: datastring,           success: function (msg) {              $("#loading").hide();                location.replace("checkout/guest_ckot?id_gst="+msg+"#pg2");               }        });     }       $('#cntaurth').click(function(){             function checkemail(){         var email = $("#email").val();         if((email.length < 6) ||          (email.indexof('@',0) < 1) ||          (email.lastindexof('@') != email.indexof('@',0)) ||          (email.lastindexof('@') > (email.length - 5)) ||          (email.lastindexof('.') > (email.length - 3)) ||          (email.lastindexof('.') < (email.length - 4)) ||          (email.indexof('..',0) > -1) ||          (email.indexof('@.',0) > -1) ||          (email.indexof('.@',0) > -1) ||          (email.indexof(',',0) > -1)){              $("#email").css("border-color","#f05f68");             return false;         }         else{             $("#email").css("border-color","#0c9");             return true;         }        }             function checkpass(){             var password = $("#password").val();             if(password == 0){                 $("#password").css("border-color","#f05f68");                 return false;                }             else{                 $("#password").css("border-color","#0c9");                 return true;                 }         }     if(!checkemail() || !checkpass()) {         return false;        }     else{         var email = $("#email").val();var password = $("#password").val();         var datastring = 'email=' + email + '&password=' + password ;         $("#loading").show();             $.ajax({                url: "includes_fm/form_submi/login_submit",                type: "post",                data: datastring,                success: function (msg) {                    if (msg == 1) {                      $("#loading").hide();                      window.location.reload();                     } else {                     $("#loading").hide();                     $("#messagesuccerr").html("<span style=color:red;                       font-size:14px>oops!! wrong credentials!!</span>")                      .fadein().delay(4000).fadeout();                    return false;                   }                 }          });     } });            });

when click submit button of continue guest have press button 2 times form validates field. why 2 clicks needed.

same happening on after validating email field. please assist.

  • your validate function has many errors (such unnecessary $('#cntaurth').click(function(){});).

  • span id="loading" in incorrect place.

  • div id="messagesuccerr" missing.

  • and other problems.

fiddle full code

validate function should like:

function validate() {     if (!checkemail())     {         return false;        }     var isuser = $(".sggn_in").is(':visible');     if (isuser)     {         if (!checkpassword())         {             return false;         }         var url = "includes_fm/form_submi/login_submit";         var datastring = 'email=' + $("#email").val() + '&password=' + $("#password").val();         makerequest(url, datastring, successuserrequest);     }     else     {         var url = "includes_fm/form_submi/checkou_guauth";         var datastring = 'email=' + $("#email").val();         makerequest(url, datastring, successguestrequest);     } }
