variables and regular expression

[andrethegiant]

is it possible to insert a variable into a regular expression string? for example, something like this:

reg = /name="val"+i+"" value="[\w]+/gi

where i is the variable (an interger, let's say). then this should work for val0, val1, val2, etc.

Well, at least that's what I want. Please help!

Yes, find a similar example below

re = "/^\\d{0," + (sLength) + "}$¦^\\d{0," + (sLength) + "}\\.\\d{0,2}$/";
re = eval(re);

You first need to create the string you want, and then use the eval function.

Later on you then use
re.test(sObjectValue)
