从批量文本中提取电子邮件（使用正则表达式JavaScript和jQuery）

Posted 2021-02-26

Easily grabs email addresses from a bulk text (CSV and/or some other email address-filled list/db).

Example #2 takes the input (bulk text) from textarea #input and puts the clean emails in the textarea #extractedemails.

function extractEmails ( text ){
	return text.match(/([a-zA-Z0-9._-][email protected][a-zA-Z0-9._-]+.[a-zA-Z0-9._-]+)/gi);
}
 
// EXAMPLE #1
var emails = extractEmails ( HugeListWithBulkTextIncludingEmailAddresses );
document.write ( emails.join('
') );
 
 
// EXAMPLE #2 (jQuery)
$(function(){
	$('#eform').submit(function(){
		$('#extractedemails').val( extractEmails($('#input').val() ).join('
'));
		return false;
	});
});
