I have a JavaScript String, for example :
var test1 = "[email protected]" ; // Function must return true in this case
var test2 = "[email protected] " ; // Function must return false in this case
I would like to build a function which return true if the String contains @ character, following by any character "bbbbbb" following by ".temp" extension.
How can I do this ?
You can use regex#test
var found = /@.*?\.temp\b/.test(str);
If you want to make it @ character, following by "bbbbbb" following by ".temp" extension then use:
var found = /@bbbbbb\.temp\b/.test(str);
@.*\.temp$ would be more efficient (.* vs .*?).
[email protected]..* vs .*? angle. For that I have added \b after \.tempRegular expression solution:
function validate(argument) {
var re = /^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
if((argument.lastIndexOf('.temp', argument.length-5)>=argument.length-5) && re.test(argument)) {
return true;
} else {
return false;
}
}
