I know that this's been asked before but none of the suggested solutions worked for me. I've got the following:
var regex = new RegExp(/D0030001 IN/gi);
$("p").filter(function () {
return regex.test(this.id);
}).css("background-color","blue");
This one works fine. However, when I try to do
spl = [];
spl[0] = "D0030001";
spl[1] = "IN";
var regex = new RegExp("/" + spl[0] + " " + spl[1] + "/gi");
$("p").filter(function () {
return regex.test(this.id);
}).css("background-color","blue");
This one doesn't work. In other words I need to use variables to construct the regex pattern. Thanks

You need to use the second argument of RegExp constructor to set the flags and you don't need / /
delimiters.
var regex = new RegExp(spl[0] + " " + spl[1], "gi");
