This method executes the search for a match between a regular expression and this String object.
Its syntax is as follows −
string.search(regexp);
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).
If successful, the search returns the index of the regular expression inside the string. Otherwise, it returns -1.
Try the following example.
<html> <head> <title>JavaScript String search() Method</title> </head> <body> <script type="text/javascript"> var re = /apples/gi; var str = "Apples are round, and apples are juicy."; if ( str.search(re) == -1 ){ document.write("Does not contain Apples" ); } else { document.write("Contains Apples" ); } </script> </body> </html>
Contains Apples
