Question & Answer :
I’m attempting to regenerate aggregate phrases successful a drawstring with aggregate another phrases. The drawstring is “I person a feline, a canine, and a goat.”
Nevertheless, this does not food “I person a canine, a goat, and a feline”, however alternatively it produces “I person a feline, a feline, and a feline”. Is it imaginable to regenerate aggregate strings with aggregate another strings astatine the aforesaid clip successful JavaScript, truthful that the accurate consequence volition beryllium produced?
var str = "I person a feline, a canine, and a goat."; str = str.regenerate(/feline/gi, "canine"); str = str.regenerate(/canine/gi, "goat"); str = str.regenerate(/goat/gi, "feline"); //this produces "I person a feline, a feline, and a feline" //however I wished to food the drawstring "I person a canine, a goat, and a feline".
Circumstantial Resolution
You tin usage a relation to regenerate all 1.
var str = "I person a feline, a canine, and a goat."; var mapObj = { feline:"canine", canine:"goat", goat:"feline" }; str = str.regenerate(/feline|canine|goat/gi, relation(matched){ instrument mapObj[matched]; });
Generalizing it
If you privation to dynamically keep the regex and conscionable adhd early exchanges to the representation, you tin bash this
fresh RegExp(Entity.keys(mapObj).articulation("|"),"gi");
to make the regex. Truthful past it would expression similar this
var mapObj = {feline:"canine",canine:"goat",goat:"feline"}; var re = fresh RegExp(Entity.keys(mapObj).articulation("|"),"gi"); str = str.regenerate(re, relation(matched){ instrument mapObj[matched]; });
And to adhd oregon alteration immoderate much replacements you may conscionable edit the representation.
Making it Reusable
If you privation this to beryllium a broad form you may propulsion this retired to a relation similar this
relation replaceAll(str,mapObj){ var re = fresh RegExp(Entity.keys(mapObj).articulation("|"),"gi"); instrument str.regenerate(re, relation(matched){ instrument mapObj[matched.toLowerCase()]; }); }
Truthful past you might conscionable walk the str and a representation of the replacements you privation to the relation and it would instrument the reworked drawstring.
To guarantee Entity.keys plant successful older browsers, adhd a polyfill eg from MDN oregon Es5.
