Question

How is it possible to match more than one string with regular expressions?

Here I want to match both name and txt, but only name is matched?

var reg = new RegExp('%([a-z]+)%', "g");
reg.exec('%name% some text %txt%');

Answer 1

The g flag does work but needs to be executed on the same string multiple times

var reg = new RegExp('%([a-z]+)%', "g");
var str = '%name% some text %txt%';
var result;

while( result = reg.exec( str ) ) { // returns array of current match
    console.log( result[1] ); // index 0 is matched expression. Thereafter matched groups.
}​

The above outputs name & txt to the console.
