How to construct a Regular Expression in Java Script for OR condition?

I want to construct a regular expression in Javascript with 'OR' condition for me to input that into a fnFilter() function call to do column multi filtering.

Let's say I want to filter a column for values either A or B.

var string1 = 'A';
var string2 = 'B';

If I use '|' between these two strings, it's treated as bit wise OR operator.

oTable.fnFilter(string1 | string 2, columnIndex, true, false);

If I use '||' between these two strings, it's treated as logical OR operator.

oTable.fnFilter(string1 || string 2, columnIndex, true, false);

What I should insert or do more to make it work like a regular expression, which brings the meaning, either A or B, and filter the column for values either A or B?

You could instance the RegExp object like so:

var filterRegEx = new RegExp(string1 + '|' + string2, 'g');
oTable.fnFilter(filterRegEx, columnIndex, true, false);

I think what you want is

'(' + string1 + '|' + string2 + ')'
