How to allow number range in regex

[harshadakashid]

There is a field call Destination port which is a single line text field and a OnChange client script is written to allow number or number range (i.e 1119 or 1100-2000)

How to write regex for this??

var regEx = /^\d+$/;

        if (!regEx.test(destination_port)) {

            g_form.showFieldMsg("destination_port", "Please enter valid Destination Port number.", "error");

This is only allowing number i.e 110 but it should allow number range i.e 2000-3000.

@harshadakashid ,

Can you please try this regex

var num_ranger = /^(\d+(-\d+)?|\d+)$/;

        if (!num_ranger.test(destination_port)) {

            g_form.showFieldMsg("destination_port", "Please enter valid Destination Port number.", "error");

}

Please mark helpful, if this helped.

Thanks,
