TypeScript - String search()

This method executes the search for a match between a regular expression and this String object.

Syntax

string.search(regexp);

Argument Details

regexp − A regular expression object. If a non-RegExp object obj is passed, it is implicitly converted to a RegExp by using new RegExp(obj).

Return Value

If successful, the search returns the index of the regular expression inside the string. Otherwise, it returns -1.

Example

var re = /apples/gi; 
var str = "Apples are round, and apples are juicy.";
if (str.search(re) == -1 ) { 
   console.log("Does not contain Apples" ); 
} else { 
   console.log("Contains Apples" ); 
} 

On compiling, it will generate the same code in JavaScript.

Its output is as follows −

Contains Apples
