string contains other or not [ 678 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); } }); };
