javascript - Custom JS Confirm Modals using jQuery.Deferred and issues with return values based on buttons -

-

i'm java developer has entered javascript world, forgive me if make silly mistakes or assumptions. attempting translate our native browser/js "confirm" dialog boxes custom modals have been developed using backbone framework. currently, these modals not support "confirm" type functionality. think primary issue modals not working asynchronously.

i have method calling opens modal, , hoping receive "true" or "false" value call depends on button user clicked. however, method returns modal displayed, , not wait button click. modal system supports seperate callbacks each button, can defined when calling "openportletmodal" method, demonstrate below. however, "confirmdiscard" method returns undefined value, without ever waiting of button calls. question is, possible pause execution of method until callback made?

while researching, did find out bit jquery.deferred,but haven't found clear way of utilizing functionality want, , no examples see seem include different return values based on callbacks.

here's sample code:

confirmdiscard: function(context) {     var deferred = new $.deferred();      mymodal.openportletmodal(context, null, {     views: [{         name: "auth",         title: "confirmation",            renderresponsedata: "this test",  //message modal renders         buttons: [{         type: "finish",         label: "ok",         click: function() {             console.log("clicked ok");             deferred.resolve("true");  //this i'd return confirmdialog() method             return false; //modal system expects "false" value callback if there no ajax call made.         },         }, {         type: "cancel",         click: function() {             console.log("clicked cancel");             deferred.resolve("false");               return false;         },         }]     }]     });      deferred.done(function(value) {                  alert(value);  //this called on button click, confirmdiscard method has returned.     return value;     })      return deferred.promise(); },

given pattern, there way in javascript have method wait while modal responded to?

i advise way yours, little different. hope you.

cutomconfirm: function(text) {     var d, rendered, template,     _this = this;      template = $('#custom_confirm_temp');     rendered = $.tmpl($(template).template(), {         text: text || ''     });      $.blockui({         message: rendered,         showoverlay: true,         onunblock: function() {             return $(document).unbind('click');         },         css: {           width: '600px',           height: '150px',           opacity: '1',           border: '0',           backgroundcolor: 'none'         }     });      d = $.deferred();      rendered.find('#ok').click(function() {         $.unblockui();         return d.resolve();     });      rendered.find('#cancel').click(function() {         $.unblockui();         return d.reject();     });      return d; }

you need create template(with id ="custom_confirm_temp" ) , call when need.

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; @
