estrarre indirizzi email da elenco

**yuri refolo** · 01-02-2005, 16:34

ho un elenco pazzesco in formato txt di indirizzi email e devo spedire una mail unica a tutti: per evitare di scriverli a mano (sarebbe la morte anche copiarli ed incollarli), ho fatto uno script, ma non funziona a dovere. mi potete dare una mano?

esempio

indirizzo1@email.com descrizione1
indirizzo2@email.com descrizione2
indirizzo3@email.com descrizione3
indirizzo4@email.com descrizione4

eccetera

che deve diventare

indirizzo1@email.com; indirizzo2@email.com; indirizzo3@email.com; indirizzo4@email.com;

eccetera

codice:

<html>
<head>
<script language="javascript">

function trovaemail() {

contenuto = document.getElementById('indirizzi').value;

indir = contenuto.split(" ");

for (x=0; x<indir.length; x++) {

if (indir[x].indexOf("@")!=-1) {
document.getElementById('risultati').value += indir[x] + "; "
}
}

}	


</script>



</head>
<body>
<textarea id="indirizzi" cols="20" rows="10"></textarea>

<input type="button" value="reset indirizzi" 

onclick="document.getElementById('indirizzi').value='';">


<textarea id="risultati" cols="20" rows="10"></textarea>

<input type="button" value="reset risultati" 

onclick="document.getElementById('risultati').value='';">



<input type="button" value="trova email" onclick="javascript:trovaemail();">
</body>
</html>

mi potrebbe anche piacere se funzionasse

**willybit** · 02-02-2005, 11:52

basterebbe una regular expression

codice:

<script>
function TrovaEmail(ff){
  var re = /[\w\-\.]+@([\w\-]+\.)+[a-z]{2,4}\]?/gi
  var stringa = ff.txt.value
  var ris = stringa.match(re)
  var strEmail=''
  for(var i=0;i<ris.length;i++)
    strEmail+=(ris[i]+'; ')
  ff.email.value=strEmail
}
</script>
<form>
<textarea name="txt" cols="80" rows="10"></textarea>


<input type="button" value="Trova indirizzi email" onclick="TrovaEmail(this.form)">


<textarea name="email" cols="80" rows="10"></textarea>
</form>
