Pass a JSON object via an AJAX call

[blirette]

Hi all,

 

I'm pretty new to using this JSON thing and would like to know why this isn't working.

 

I'm trying to get via AJAX some infos that I'd like to be formatted in JSON so I can parse them easily. A PHP page is generating this string :

 

{"lastName":"Hope","firstName":"Bob","email":"bobhope@hotmail.com"}

 

I'm trying to retrieve it from another PHP page via this :

 

var aInfos = xmlhttp.responseText;

alert(aInfos.firstName);
alert(aInfos.lastName);
alert(aInfos.email);

 

But it doesn't seems to work. It says "undefined".

 

When I replace "xmlhttp.responseText" with "{"lastName":"Hope","firstName":"Bob","email":"bobhope@hotmail.com"}", it works.

 

What am I missing?

 

Thanks for your time and have a nice day!

I love to solve things by myself!

 

I had to eval() it.

 

var JSONFile = xmlhttp.responseText;
eval(JSONFile);
