javascript - change jquery chosen max_selected option dynamically -

-

i've 2 select option, class , class_attr class has 2 options: , b class_attr has many options: aa, bb, cc, dd, ee, ...

my question is, how implement if user choose a, chosen max_selected 5 options, , if user change b, chosen max_selected 3 options.

i'm trying this:

$(".class").change(function(){         var code = $(this).val();         if(code == 1){            $(".class_attr").chosen({max_selected_options: 5});             }         else{                $(".class_attr").chosen({max_selected_options: 3});                   }         $(".class_attr").trigger("liszt:updated"); });

but seems can't work, option list class_attr set once (the first class max_selected_options value selected, whether 5 or 3) , never updated max_selected_options after first time. thank you~

try this:

$('.class').chosen().change(function () {      var code = $(this).val();     var maxoptions = code == 1 ? 5 : 3;      $(".class_attr").chosen('destroy').chosen({ max_selected_options: maxoptions }); });

it looks can't change options after it's been initalised has destroyed before being created once more.

this error has shown on many times, seems. prominent answer issue seems restkit 0.20 — coredata: error: failed call designated initializer on nsmanagedobject class however, solution posted doesn't work me. let's start beginning: i want upload file server. want parse response make sure uploaded. if not, try again later. model has boolean variable called nsnumber *senttoserver purpose (in coredata, bool saved nsnumber ) . because don't know whether sending going successful, save entity coredata model first before sending via restkit. when post request successful, server returns json string this: {"id":14,"created":true} notice that, of course, id not set on coredata model yet, both id , created new informations model. here's model: @interface recording : nsmanagedobject @property (nonatomic, retain) nsstring * audiofilepath; @property (nonatomic, retain) nsdate * createdat; @property (nonatomic, retain) nsstring * deviceid; @
