I''m not the best when it comes to javascript so this is probably a
simple mistake. I''m using the following code to read an external json
file and print out its values. The problem is when I try to write the
value to the browser it causes the browser to load like it hasn''t
finished the javascript code. Its writing the value to the screen so I
think its hanging after that point. I also tried the document.write
outside of the Ajax.Request but then the json variable is not defined.
I was however able to make this working using
document.getElementById().innerHTML instead of document.write but it
would be easier if document.write would work. Any clue as to what I''m
doing wrong?
CODE
new Ajax.Request(''http://www.domain.com/test.json'', {
method:''get'',
onSuccess: function(transport){
var json = transport.responseText.evalJSON();
document.write(''ID: '' + json.items[0].id);
},
onFailure: function(){ alert(''Something went wrong...'') }
});
JSON FILE
{"items":[
{"id":"1202263067"},
{"id":"1201111878"}
]}

As Justin pointed out, if you are debugging, firebug (and firebug lite in non-firefox browsers) and it''s console.log method work fine. If you want to update the page, you can use Element#update or Element#insert, provided by Prototype. http://prototypejs.org/api/element/update http://prototypejs.org/api/element/insert One other thing, Prototype provides an "extended" response object, that has a ''responseJSON'' property. So instead of transport.responseText.evalJSON() you can just call transport.responseJSON. http://prototypejs.org/api/ajax/response Best, -Nicolas On Feb 10, 2008 9:51 PM, Burst Web Solutions <david-pkrbDg1FnOcJvtFkdXX2HsPWbZVgNyiZ@public.gmane.org> wrote:> > > > > > Its writing the value to the screen > > > > That''s what happens when you use document.write like that.
