使用JQuery UI对话框返回false确认对话框

Question

I am going to submit a form after validating the form as follows, here first I use a ajax post and check whether duplicate values are exist if exist ajax will return html code else return 'false'. Dialog box should popup if ajax return is a 'html code'. If ajax return is false form_validate() should return true. Which means no duplicates, form will submit for insert data. If user clicked Ok on the Dialog box, form_validate() should return true which means there are duplicates, form will submit for update data. If user clicked Cancel form_validate() should return false which means form will not submit. I am working on this hours but couldn't figure it out. Plz Help.

   function form_validate(){

         $.post('index.php',{ .....

                             },function(result){ 

                                if(result!='false'){
                                  $('<div></div>')
                                          .html(result+'<br/>Click OK to confirm.  Click Cancel to stop this action.')
                                          .dialog({
                                                         buttons : {
                                                                "OK": function() { 
                                                                   $(this).dialog("close");                       
                                                                   return true;
                                                                 }, "Cancel": function() {
                                                                        $(this).dialog("close");

function form_validation(){
             $.post
              .....
              .....
            ,function(result){        



                           if(result!='false'){
                               $('<div></div>')   
                                      .html(result+'<br/>Click OK to confirm.  Click Cancel to stop this action.')   
                                      .dialog({   
                                   buttons : {
                                        "OK": function() { 
                                              $(this).dialog("close");                       
                                              $('#adminForm3').submit();
                                        }, "Cancel": function() {
                                              $(this).dialog("close");
                                        }
                                   }});
                           }
                           else{                                  
                               $('#adminForm3').submit();
                           }
                           return ;

                           });
return false;
}

add form id as adminForm3. This will work fine.
