JavaScript Regex Ignore Case

Question

I am trying to match a part of the string and it should be NOT case sensitive. I have the following code but I never get the replaced string.

var name = 'Mohammad Azam'
var result = name.replace('/' + searchText + '/gi', "<b>" + searchText + "</b>");

The searchText variable will be "moha" or "mo" or "moh".

How can I get the matching thing in bold tags.

Answer 1

/pattern/ has meaning when it's put in as a literal, not if you construct string like that. (I am not 100% sure on that.)

Try

var name = 'Mohammad Azam';
var searchText = 'moha';
var result = name.replace(new RegExp('(' + searchText + ')', 'gi'), "<b>$1</b>");
//result is <b>Moha</b>mmad Azam
