Salve,
con jquery faccio il parse del cookie poi JSON.stringify estraggo solo le keys con h2s come prime 3 lettere poi vorrei verificare se hanno valori vuoti o no ma non funziona...ecco il codice
codice:
 
var test = JSON.parse($.cookie('configurationFormPre-treatment'));
                         JSON.stringify(test, function(key, value) {
                                // when encoutering one of the keys we're looking for, populate our own result
                                if (key.substr(0, 3) == 'h2s') {
                                     if (value == "") {
                                       
                                        $("#img-checked-PRE-TREATMENT-icon-delete-h2s").css("opacity", "0.5");
                                    $("#img-checked-PRE-TREATMENT-all-h2s").attr("src", "<?php echo THEMEURL;?>/images/checked-white-no.png");  
                                   }else{
                                    
                                     $("#img-checked-PRE-TREATMENT-icon-delete-h2s").css("opacity", "1");
                                    $("#img-checked-PRE-TREATMENT-all-h2s").attr("src", "<?php echo THEMEURL;?>/images/checked-white.png");  
                                    
                                   }  
                                } 
                                // in any case, don't break the normal generation of the JSON.parse result
                                // (or the keys we select above would have been left empty!)
                               

                            });
un piccolo aiutino?
grazie
