Re: [was: Stripping down Cocoon] AW: JSON
I am using Ajax to post a request to a servlet which formats the response as
a JSON string resembling:
{
"prop1":"prop1Value",
"prop2":"prop2Value",
"prop3":"prop3Value"
}
I use this client code to convert it to a JSON object:
var func = new Function("return "+data);
var jsonObj = func();
jsonObj.prop1 ...
Can you direct me as how to dynamically cycle through a properties object
and retrieve the elements and values when i do not know what the properties
will be since i am building this dynamically from a result set on the
server?
I will be pulling these values and wrapping them in DOM objects for display
on a web page. I've used arrays, but i would prefer to have a standard
return string and we would like to use the JSON properties object.
Thanks in advance,
Mike

This isn't a Cocoon-specific question, but I can answer...
Use the JavaScript for...in loop:
for(var prop in jsonObj) {
var propValue = jsonObj[prop];
...
