[Javascript] Search for a substring in a string

[Andrew Gibson]

Try this:

var mystr = "these dogs are dirty"
var found=mystr.indexOf("dogs")

//  found would be an integer where the str is...  -1  means not found

Subject: [Javascript] Search for a substring in a string


Forgive me if my questions are too basic.

I want to check for the existence of a substring within a string, more or
less like
the hypothetical syntax below :

var mystr = "these dogs are dirty"

if (mystr contains "dogs") {do stuff }
