Use a jsp or servlet to process your form data - have a look at the following article http://www.javaworld.com/javaworld/jw-03-2000/jw-0331-ssj-forms.htmlRichard

Ok,

to read data from the following sample form using a jsp:

<html>

<head>

</head>

<body>

p1: <input type=text name=p1>

p2: <input type=text name=p2>

</form>

</body>

</html>

the jsp page (you can do the same thing with a servlet)

my.jsp

<html>

<head>

</head>

<body>

String newp1 = request.getParameter("p1");

String newp2 = request.getParameter("p2");

out.println("p1 = " + newp1);

out.println("p2 = " + newp2);

</body>

</html>

Hopefully that'll get you started, you should have a look at the tutorials on Sun's site too.

Hi,in jsp & servlet, you can get back all the field names of your form with request.getParameterNames();you can either find the value of a field in your form with request.getParameter(yourFieldName);hope this helps !Badr.

var fields = this.fields = new Object();

for (var e = 0; e < form.elements.length; e++) {

var field = form.elements[e];

if (field.name) {

if ((field.type.toLowerCase() == 'text'

|| field.type.toLowerCase() == 'textarea'

|| field.type.toLowerCase() == 'password'

|| field.type.toLowerCase() == 'file')

&& field.value)

fields[field.name] = field.value;

else if ((field.type.toLowerCase() == 'checkbox'

|| field.type.toLowerCase() == 'radio')

&& field.checked)

fields[field.name] = field.value;

else if (field.type.toLowerCase() == 'select-one'

fields[field.name] =

field.options[field.selectedIndex].value;

else if (field.type.toLowerCase() == 'select-multiple'

&& field.selectedIndex != -1) {

fields[field.name] = new Array();

for (var i = 0; i < field.options.length; i++)

function urlEncode (string) {

string = string.replace(/ /g, '+');

return escape(string);

}

function FormData_toQueryString () {

var r = '';

for (var field in this.fields)

if (typeof this.fields[field] != 'string')

for (var i = 0; i < this.fields[field].length; i++)

r += urlEncode(field) + '=' + urlEncode(this.fields[field])

+ '&';

else

r += urlEncode(field) + '=' + urlEncode(this.fields[field]) + '&';

r = r.substring(0, r.length - 1);

return r;
