data from forms

is there any easy way to get data from a form?
(so called datastream i guess)


now im using this script (if anyone interested):

function ff(f) {
var r=Array(),i=j=k=0,fl,t;
if(f&&(f.tagName=='FORM')) {
fl=f.length;
for(i=0;i<fl;i++) {
t=false;
switch(f.elements[i].type) {
//checkbox:
case 'checkbox':
//radio:
case 'radio':
if(t=f.elements[i].checked) r[++k]=f.elements[i].name+'='+(f.elements[i].value?f.elements[i].value:1);
break;
//select:
case 'select':
case 'select-one':
r[++k]=f.elements[i].name+'='+f.elements[i][f.elements[i].selectedIndex].value;
t=true;
break;
case 'select-multiple':
for(j=0;j<f.elements[i].length;j++) {
if(f.elements[i].options[j].selectedIndex) {
r[++k]=f.elements[i].name+'='+f.elements[i].options[j].value;
t=true;
}
}
break;
default:
r[++k]=f.elements[i].name+'='+f.elements[i].value;
t=true;
}
report(encodeURI(r[k]));
if(t)r[k]=(String(encodeURI(r[k])).split('&')).join('%26');
}
//report(r);
}
return r;
}



one more thing - when will we get something similar to php tag for javascript:)?
