javascript - Is there a way to set 'CallBack' in `jQuery` custom `trigger`? -


i trying replay trigger receiver. using jquery custom trigger event. if wrong please correct me. if there way this, please let me know..

we can set trigger in receiver, agree. can implement callback?

here try:

var receiver = function() {       console.log('trigger received');   return "sending hellow world!"; }  $(document).on("getready", receiver);  var triggerer = function() {       var callback = function(msg) {           console.log("msg received", msg);   }    $(document).trigger("getready", callback); }  triggerer();

live demo

you can use second parameter of $.trigger. should array of additional parameters passed custom event.

that way, can pass callback , use inside receiver.

note jquery always pass own event object first parameter receiver.

var receiver = function(e, callback, otherparam){    console.log('trigger received');    callback && callback.call(e, "sending hello world! " + otherparam);  };    var triggerer = function(){    var callback = function(msg) {      console.log("msg received", msg);    };    $(document).trigger("getready", [callback, 1337]);  };    $(document).on("getready", receiver);    triggerer();

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 -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
