javascript match
match() method checks whether a pattern exists or not in a string. If it matches,
return the matched substring.
var s = "endmemo.com";
var m = s.match(/end/);
alert(m); //end
//If matches multiple times, return the first
var m = s.match(/m./);
alert(m); //me
If
//g flag is used and there are multiple matches, return all matches as an array.
var m = s.match(/m./g);
alert(m[0]); //me
alert(m[1]); //mo
If
() is used and no
g flag, return the first match and all matches in
() as an array.
var s = "endmemo.com";
var m = s.match(/m(.)/);
alert(m[0]); //me
alert(m[1]); //e
var m = s.match(/m(.)/g);
alert(m[0]); //me
alert(m[1]); //mo
alert(m[2]); //undefined
Use variables in string match
var str = "endmemo.com";
var pat= new RegExp("me","g");
if (str.match(pat))
{
alert("m");
}
