[jQuery] Reading json strings
<html>
<body>
Hi folks,
I don't understand what I'm doing wrong in the following code
(<a href="http://temporarius.massey.ac.nz/json_test.htm" eudora="autourl">
http://temporarius.massey.ac.nz/json_test.htm</a>) where I cannot seem to
"harvest" the returned json string.
The test json string being returned after the form is submitted
is:
<pre>{"fields": [{"id": "name",
"isValid": false, "message": "Username must be
at least 3 characters long"}]}
</pre>(there is absolutely no connection to the contents of the form
being passed to the server and the json string returned - I'm just trying
to understand the system)
My jq code is<font face="Courier New, Courier">:
$(document).ready(function() {
var AFoptions = {
before: fnAF_Before('7'),
dataType: 'json',
after: function(json) {
if (json.fields) {
alert(json.fields.length);
for (var i = 0; i < json.fields.length; i++) {
var field = json.fields[i];
alert(field);
}
}
}
};
$('#asset_form').submit(function() {
$(this).ajaxSubmit(AFoptions);
return
false;
});
});
function fnAF_Before(q){
$("#theIndicator"+q).show();
}
</font>I don't understand why the length of "fields" is being
given as 1, and when I try to view the components of fields, I get an
[object Object] error.
I'd appreciate some insight here.
Thanks,
Bruce
