Given the following email address -- [email protected] -- how can I extract someone from the address using javascript?
Thank you.
Regular Expression with match
with safety checks
var [email protected];
var nameMatch = str.match(/^([^@]*)@/);
var name = nameMatch ? nameMatch[1] : null;
written as one line
var name = str.match(/^([^@]*)@/)[1];
Regular Expression with replace
with safety checks
var [email protected];
var nameReplace = str.replace(/@.*$/,);
var name = nameReplace!==str ? nameReplace : null;
written as one line
var name = str.replace(/@.*$/,);
Split String
with safety checks
var [email protected];
var nameParts = str.split(@);
var name = nameParts.length==2 ? nameParts[0] : null;
written as one line
var name = str.split(@)[0];
