javascript - marionette control from backbone controls -

-

i want create mariontte control consists of 3 backbone controls. first date picker, second numeric stepper , third 1 again date picker. idea first date initial date , numeric stepper adds days , result shown in second date picker. anyway don't know how create marionette view when not child items same. how should approach this?

i think can create compositeview(or layout can work) having 3 divs , render 3 different itemviews in 3 divs explicitly adding el of itemviews in divs

e.g. if following compositeview template

<div id="first-datepicker"></div> <div id="numeric-stepper"></div> <div id="second-datepicker"></div>

then in compositeview js can render itemviews follows

ui:{     firstdatepicker: "#first-datepicker",     numericstepper: "#numeric-stepper",     seconddatepicker: "#second-datepicker" }, onrender: function(){     this.ui.firstdatepicker.html(new datepickerview().render().el);     this.ui.numericstepper.html(new numericstepperview().render().el);     this.ui.firstdatepicker.html(new datepickerview().render().el); }

but in case of layout not need explicitly render view, can use show method of layout as

regions:{     firstdatepickerregion: "#first-datepicker",     numericstepperregion: "#numeric-stepper",     seconddatepickerregion: "#second-datepicker" }, onrender: function(){     this.firstdatepickerregion.show(new datepickerview());     this.numericstepperregion.show(new numericstepperview());     this.seconddatepickerregion.show(new datepickerview()); }

i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response...
