Query and Map reload

[Eduardo Zenaide]

Steve,

to be more especific, i'm using javascript to do queries. so i'm trying to
convert on variables some mapserver parameters to build the map based on the
query.
so far i have these:

    var layer = document.pesquisa.layersList.value; //html comboBox to
select layer
    var item = document.pesquisa.busca.value; //html input value
    var operador = document.pesquisa.operadores.value; //another comboBox
for operators

and now the big problem. the next variable is based on html inputs i
generate through $gpoMap->extent->minx, for example. but it will return the
last map extension, not the one based on the query.

    var minx = "minx=" + window.opener.document.myform.var_minx.value + "&";

so, what i want is how to know the extension (minx, miny...) from the query.
how to know the extension the query will return before the user submit?


thanks
