RegExp test() method
Description
test() accepts a string and returns true if the pattern matches the argument and false if it does not.
Example
The test() method is often used in if statements, such as the following:
var text = "000-00-0000";
var pattern = /\d{3}-\d{2}-\d{4}/;
// ww w . j a va2s .c o m
if (pattern.test(text)){
console.log("The pattern was matched.");
}
The code above generates the following result.
