myString.replace( VARIABLE, “”) … but globally

Question

How can I use a variable to remove all instances of a substring from a string? (to remove, I\'m thinking the best way is to replace, with nothing, globally... right?)

Answer 1

You have to use the constructor rather than the literal syntax when passing variables. Stick with the literal syntax for literal strings to avoid confusing escape syntax.

var oldWordRegEx = new RegExp(oldWord,'g');

myString.replace(oldWordRegEx,"");
