METHOD:
String::search
object.search(regexp)
This method is used
to search for a match between a regular expression and the specified string. If a match is found, the search method returns the index of the regular expression within the string. If no match is found, a value of -1 is returned.
The first example of code below uses the search method to look for a match between the regular expression 'rExp' and the characters in the 'myString' string object and displays the resulting value in the browser. In the second example, removing the 'i' (ignore case) flag from the regular expression causes the value of the search to be returned as -1
Code:
myString = new String("Go to DevGuru.com")
rExp = /devguru.com/gi;
results = myString.search(rExp)
document.write(results)
Output:
6
myString = new String("Go to DevGuru.com")
rExp = /devguru.com/g;
results = myString.search(rExp)
document.write(results)
Output:
-1
