if statement wildcard

Basically Im wondering how to go about using a wildcard in an if statement.

Example being:

function blah()
{
var something="thisisatopsecretmessage"
if (something==*secret*)
{
document.write("Found Secret")
}
else
{
document.write("No Secret Found")
}
}

I know this is no doubt very basic, but how would I go about changing the if so its basically 'If something has secret in it, do this, else, do that'.

You'll need to use Regular Expressions -

Or, you could use the indexOf function.


if (something.indexOf("secret") > -1)

indexOf returns the location of the first occurance of the string "secret" within something. If it's not found, it returns -1.
