[jQuery] Some jQuery Questions
Now that getting a handle on the JS/jQuery language, I have these
basic questions
1) For an JSON object, how do you get the key name?
Example
var json = {field1: "data2", field2: "data2"};
I know how to get the data, but how do you get the field names? IOW, I
want to get the names of the keys.
Is there a method that traverses the JSON and returns key/value?
Do I need regex() or is there a more direct method?
2) Best way to create a toJSON() string or object.
I didn't see a direct way to do this, if not, is this best way:
// Create JSON from form input id="wc*" fields
$jj = $('input[@id^=wc]').get();
json = {};
try {
for (var j=0; j <$jj.length; j++) {
json[$jj[j].getAttribute("name")] = $jj[j].value;
}
} catch(e) {
alert("EXCEPTION:\n\n"+e);
return false;
}
TIA
