Is it possible to pass the values of variables obtained in my
javascript code executing before the ajax call to the script i execute
after the ajax call returns?
basically i have a dynamic form that gets new elements based on some
logic depending on what the user clicks. The form has some text input
fields that they can fill in as they customize the form...but the
problem is that anything they type in gets forgotten when the form is
updated with a new element (because i completely reconstruct the form
with each element added).
What im attempting to do in the script that executes before the ajax
call is to read in all the values of each input field. then, when the
ajax call returns and the form is regenerated, i want to fill in the
fields with the values they had before the call.
hopefully thats not too confusing and someone can point me in the
right direction.
thanks!
heres the code i have:
echo $ajax->link("link",
array('controller' => 'units',
'action' => 'getUnits', $unit['Unit']['id']),
array('update' => 'builder',
'before' => '
var notes = new Array
();
if(document.build_form)
{
for(var i=0; i
< document.build_form.elements.length;i++){
if
(document.build_form.elements[i].name.substr(0,4) == "note"){
notes.push(document.build_form.elements[i].value);
}
}
}
notes.reverse();
',
'after' => '
var note = "";
if(document.build_form)
{
for(var j=0;
j<document.build_form.elements.length;j++){
if
(document.build_form.elements[j].name.substr(0,4) == "note"){
note = notes.pop();
if(note)
document.build_form.elements[j].value = note;
}
}
}
