search Method


function search(rgExp : RegExp) : Number

rgExp: Required. An instance of a Regular Expression object containing the regular expression pattern and applicable flags.

The search method indicates whether a match is found. If a match is found, the search method returns an integer value that specifies the offset from the beginning of the string where the match occurred. If no match is found, it returns -1.

The following example illustrates the use of the search method.

function SearchDemo(){ var r, re; //Declare variables. var s = "The rain in Spain falls mainly in the plain."; re = /falls/i; //Create regular expression pattern. r = s.search(re); //Search the string. return(r); //Return the index to the first match //or вЂ“1 if no match is found. }

   var s = "The rain in Spain falls mainly in the plain.";
   re = /falls/i;               //Create regular expression pattern.
   r = s.search(re);            //Search the string.
   return(r);                   //Return the index to the first match
                                //or вЂ“1 if no match is found.
