Hey guys,
Thanks for the great responses!
The other day I ended up creating my associative array on the server side so
that it instead of an array of objects, it output a JSON string that was of
the format :
'{ { "VidID":1, "VidPathStr":"somepath", "VidDescrip":"somedescription" }, {
"VidID":2, "VidPathStr":"Ima path", "VidDescrip":"blah blah" } , ...} '
...this was different than what I had before which was indeed '[ { hash1...
}, { hash2... } ...]'
This way I was able to access the hashes as in the for loop below:
function SearchVidSid2(SID) {
var pars = 'FORM.Sid=' + parseInt(SID);
var url = "/ss/Model/AjaxCalls/caller_getVidsBySid2.cfm"
new Ajax.Request(url,
{
method: 'post',
parameters: pars,
onComplete: function(transport) //get from JSON string
{
var jsonarray = transport.responseText.evalJSON(true);
for (var i=0; i < Object.keys(jsonarray.VidID).size();
i++) {
// for simplicity's sake in demonstrating how I
accessed the values in the hashes, showing alerts for each iteration
alert(Object.values(jsonarray.VidID)[i]);
alert(Object.values(jsonarray.VidPathStr)[i]);
alert( Object.values(jsonarray.VidDescrip)[i]);
}
....
How does that look?
(btw, in response to your message, in Seattle it's 3:03 a.m.... time to go
to bed (finally)! :) ...would like to hear your thoughts though!
cheers,
Mark
