I'm trying to do something that is probably very basic for most.
I'm trying to send an Ajax.Request while validating a form. I'd like
a JSON response like this:
{success: true, htmlCode: "blah, blah, blah"}
Help is always greatly appreciated.
Attempt
1

This sends back the right response, but I can't parse it so that I
know it was successful and then use the htmlCode. It just updates the
div tag with the entire JSON response.
function ajaxRequest(){
var url = "/cgidev2p/r_chgpwd.pgm";
var pars = 'v_current=' + escape($F('v_current')) +
'&v_new=' + escape($F('v_new')) + '&v_confirm=' + escape($F
('v_confirm')) + '&sessionid=' + escape($F('sessionid'));
var target = 'v_messege';
var ajaxObjhttp = new Ajax.Request(url, {
method: 'post',
parameters: pars,
onCreate: function(transport){
var myAjax = new Ajax.Updater(target, url, {
method: 'get',
parameters: pars
});
//alert("Creating New Ajax Call");
},
onSuccess: function(transport){
var json = transport.responseText.evalJSON();
var submitObj = document.getElementById
('goButton');
if (json.success) {
submitObj.disabled = false;
document.getElementById('goButton').focus;
}
else {
submitObj.disabled = true;
}
}
});
}

I think this is more what I need. It makes the request, but again I
don't know how to handle the json coming back so that I know if it was
successful and then use the second parm.
function ajaxRequest2(){
var url = "/cgidev2p/r_chgpwd.pgm";
var pars = 'v_current=' + escape($F('v_current')) +
'&v_new=' + escape($F('v_new')) + '&v_confirm=' + escape($F
('v_confirm')) + '&sessionid=' + escape($F('sessionid'));
new Ajax.Request(url, {
method: 'get',
parameters: pars,
onSuccess: function(transport){
var json = transport.responseText.evalJSON
(true);
// v_messege.update(json).setStyle
({ background: '#dfd' });
alert(json);
}
});
}
