javascript - RegExp : How to replace the second occurrence using object? - 


function converthtml(str) {   var obja={'&':'&​amp;','<':'&​lt;','>':'&​gt;','\'':'&​apos;','"':'\&​quot;'}   var matchstr = str.match(/([&|''|""|>|<])/g)   var matchstr1=''   for(var i=0; i<matchstr.length; ++i){       matchstr1 = str.replace(matchstr[i], obja[matchstr[i]])    }   return matchstr1; }  console.log(converthtml("hamburgers < pizza < tacos "));

output i'm getting hamburgers &​lt; pizza < tacos. want hamburgers &​lt; pizza &​lt; tacos. possible replace second occurrence using code changes ?.

i suggest use following approach.

var objmap = {             // ===> object specified keys    '&': '&​amp;',            // ===> have replaced    '<': '&​lt;',             // ===> corresponding values    '>': '&​gt;',    '\'': '&​apos;',    '"': '\&​quot;'  }    function converthtml(str) {    var res = str.replace(/[&<>\\"]/g, match => objmap[match]);    return res;  }    console.log(converthtml("hamburgers < pizza < tacos "));

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 -

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...
