Hi there
I have a little function that validates whether a string entered is syntactically correct
function str_validate() {
var patt=/^[a-z]{3}w(prd|uat|dev)\\d{1}$/;
val = document.getElementById("hostname").value;
if ((val.length > 7) && patt.test(val)) {
// do some good stuff
} else {
alert("Invalid string Name");
ClearForm();
}
}
}
as you can see I am matching against 8 characters made up of 3 alphas, a ‘w’, a three character string of ‘prd’, ‘uat’ or ‘dev’ and then a single numeric
what i am looking to do is to extract into a variable the three character string (‘prd’, ‘uat’ or ‘dev’) so that i can use it to work with in another function …
does anybody know how I would be able to extract this part of the string (its always the 5th,6th and 7th character of the 8 charachter string)
any help would be greatly appreciated
