javascript - backbone.js: Prevent listener event from firing when model changes -


i have following listener in view when model changed:

this.listento(this.model, 'change', this.render);

when change model : 

model.set('foo', bar);

is possible make not trigger listener event specific function call? still want event trigger @ other calls.

from fine manual:

generally speaking, when calling function emits event (model.set, collection.add, , on...), if you'd prevent event being triggered, may pass {silent: true} option. note rarely, perhaps never, idea. passing through specific flag in options event callback at, , choose ignore, work out better.

so if don't want specific set call trigger change event then:

model.set('foo', bar, { silent: true });

or tunnel information render using custom option:

model.set('foot', bar, { ignore_this: true });

and adjust render:

render: function(options) {     if(options && options.ignore_this)         return;     // ... }

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -
