Ciao,
qualcuno sa come modificare questo script, in modo che si possa recuperare il valore dei campi con $_POST di php? In particolare, il valore recuperato deve essere nella forma
valore1|valore2|valore3.
Ecco il codice:
<html>
<head>
<script language="Javascript" type="text/javascript">
<!--
//Add more fields dynamically.
function addField(area,field,limit) {
if(!document.getElementById) return; //Prevent older browsers from getting any further.
var field_area = document.getElementById(area);
var all_inputs = field_area.getElementsByTagName("input"); //Get all the input fields in the given area.
//Find the count of the last element of the list. It will be in the format '<field><number>'. If the
// field given in the argument is 'friend_' the last id will be 'friend_4'.
var last_item = all_inputs.length - 1;
var last = all_inputs[last_item].id;
var count = Number(last.split("_")[1]) + 1;
//If the maximum number of elements have been reached, exit the function.
// If the given limit is lower than 0, infinite number of fields can be created.
if(count > limit && limit > 0) return;
if(document.createElement) { //W3C Dom method.
var li = document.createElement("li");
var input = document.createElement("input");
input.id = field+count;
input.name = field+count;
input.type = "text"; //Type of field - can be any valid input type like text,file,checkbox etc.
li.appendChild(input);
field_area.appendChild(li);
} else { //Older Method
field_area.innerHTML += "[*]<input name='"+(field+count)+"' id='"+(field+count)+"' type='text' />";
}
}
//-->
</script>
</head>
<body>
<form name="frm" method="POST" action="get.php">
Friends List
- <input type="text" name="friend_1" id="friend_1" />
- <input type="text" name="friend_2" id="friend_2" />
<input type="button" value="Add Friend Field" onclick="addField('friends_area','friend_',10);" />
<input type="submit" name="submit" value="Visualizza l'anteprima e pubblica.">
</form>
</body>
</html>
Conoscendo poco il javascript non ne sono venuto a una dopo innumerevoli tentativi.
Help!
