Question

If data is submitted via POST through the classic HTML form method is it possible to access those values using standard Javascript without libraries? How would this be done?

Edit for clarity: The variables have been posted. I am trying to access those values via javascript.

Answer 1

Thinking outside the box: (A hack that should never see the light of day)

For this example the posted variable is “a”:

var val=document.URL;
var start;
start = val.search(/a=/);
var end;
end = val.search(/&/);
var thispos = val.substring(start+2,end);

1. document.URL returns the url of the current site.
2. val.search returns the position of the first occurrence of the regular expression in
   the parameter field.
3. substring the two and…
4. thispos now contains the posted variable.

Brutal but functional. Is this too terrible to be an answer?
