ok, here is an effort to sum up the code..
*
function initialiseLegendLayerGroupEntry(a,b,c,d,e,f) {
var x;
$("#division_name").bind("click", function() {
if(this.value == "sth") {
y=callFunction(a,b,c,d,e,f);
$.ajax({
type: "POST",
url: "/serverFunction/",
data: {project_name:d,layer_name:e,group_name:f},
success: function(msg){
$("#an entry point for html files that are
served").after(msg);
alert( $("#division where the wanted value is
stored").val() ); // this alert window pops up at the end.
x= $("#division where the wanted value is
stored").val();
}
});
alert(x); // this pop up window is always empty. it opens while i
still receive "print" commands from my server script !
}
});
}
I think this code is a good example of my problem. Can you identify an
error somewhere?
thanks,
