string contains other or not [ 1033 views ]
in c# we can use to check a string
// This example demonstrates the String.Contains() method
using System;
class Sample
{
public static void Main()
{
string s1 = "The quick brown fox jumps over the lazy dog";
string s2 = "fox";
bool b;
b = s1.Contains(s2);
Console.WriteLine("Is the string, s2, in the string, s1?: {0}", b);
}
}
/*
This example produces the following results:
Is the string, s2, in the string, s1?: True
*/
So I need a similar function in javascript. Here is:
if (!String.prototype.Contains) {
Object.defineProperty(String.prototype, 'Contains', {
enumerable: false,
configurable: false,
writable: false,
value: function (s) {
return !!~this.indexOf(s);
}
});
};
