I'm watching Firebug and the responses from my php backend which is
returning either XML or JSON and I am seeing a second response from my
PHP back-end. The first (at least what I assume is the first) request
gets a valid response and I update the DOM accordingly. Then shortly
there after I witness a second request with an empty POST, my PHP back-
end responds accordingly... in this case $_POST was empty so I return
an error in a JSON string. But I've already handled an onSuccess
event so my client script doesn't do anything. Below is my function
called by an onClick event from a button in the DOM.
Can some one point out to me why there is at least a second request
being made AFTER the onSuccess?
cnt = 0;
function selectCompositeList(thisform) {
try {
var url = apphome + 'screening/compositelists/
process_hwi_compositelists.php';
var frm = thisform.serialize(true);
frm.action = 'GET_HEADERS';
var ajaxReq = new Ajax.Request ( url,
{
parameters: frm,
onSuccess: function(transport, json) {
try {
while($('hwiCompositeList_headers').childNodes[0]) {
$('hwiCompositeList_headers').removeChild($
('hwiCompositeList_headers').childNodes[0]);
}
var respObj =
transport.responseText.evalJSON();
var lvgrd =
$('hwiCompositeList');
var hdtr =
$('hwiCompositeList_headers');
for (var k=0; k <
respObj.cols.length; k++){
var hdtd =
document.createElement('td');
hdtdtxt =
document.createTextNode(respObj.cols[k]);
hdtd.appendChild(hdtdtxt);
hdtr.appendChild(hdtd);
}
clearMessages();
// this block of code is here
for debugging purposes only at
this point...
// i intend on calling a second
function for a second Ajax call
using the respObj.id in the requestParemeters
var div = $('messages');
var dvclid =
document.createTextNode("clid: " + respObj.id +
"<br />cnt: " + cnt++ );
$('messages').appendChild(dvclid);
} catch (err) {
clearMessages();
var divmsg = $('messages');
while(divmsg.childNodes[0]){
divmsg.removeChild(divmsg.childNodes[0]);
}
var errors =
document.createTextNode(err);
divmsg.appendChild(errors);
divmsg.style.display = 'block';
}
},
onFailure: function() {
clearMessages();
var divmsg = $('messages');
var err = "Could not finish the request
for a composite list.";
while(divmsg.childNodes[0]){
divmsg.removeChild(divmsg.childNodes[0]);
}
var errors =
document.createTextNode(err);
divmsg.appendChild(errors);
divmsg.style.display = 'block';
return false;
}
}
);
return false;
} catch (err) {
clearMessages();
var divmsg = $('messages');
while(divmsg.childNodes[0]){
divmsg.removeChild(divmsg.childNodes[0]);
}
var errors = document.createTextNode(err);
divmsg.appendChild(errors);
divmsg.style.display = 'block';
}
}
