I am trying to figure out how to use Ajax with Prototype. I see from
http://www.sergiopereira.com/articles/prototype.js.html#UsingAjax
there is an example for a get:
var empID = $F(''lstEmployees'');
var y = $F(''lstYears'');
var url = ''http://yourserver/app/get_sales'';
var pars = ''empID='' + empID + ''&year='' +
y;
var myAjax = new Ajax.Request(
url,
{
method: ''get'',
parameters: pars,
onComplete: showResponse
});
and here is an example of a post:
var url = ''edit.php'';
var pars = ''id='' + obj.id +
''&content='' + new_content;
var myAjax = new Ajax.Request(url, {method:''post'',
postBody:pars, onSuccess:success, onFailure:failure});
What is the difference, it looks like the post and get use the same
type of pars string:
Post var pars = ''id='' + obj.id +
''&content='' + new_content;
Get var pars = ''empID='' + empID +
''&year='' + y;
Is there any difference when passing data?
Thank,
-T

Remember to encode you parameters if you are planning to concatenate them like in your example. var pars = ''id='' + obj.id + ''&content='' + encodeURIComponent( new_content ); I don''t know if that''s what you''re asking, but the difference is how the parameters are sent to your server code. An HTTP GET will sim-ply put all your parameters in the querystring (in the URL) and that approach has some length limitations so don''t expect to be passing a bunch of textarea values in there. Using an HTTP POST the parameters are sent as part of the request body, without the same limitations of the GET. On the server, the way you read the values back is normally different (I don''t know what is your backend). For example in PHP you''d use $_POST vs $_GET and in ASP.NET you''d use Request.Form[ ] vs Request.QueryString[ ] Hope it helps - Sergio On May 10, 11:55 am, -T <gsecurity...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> I am trying to figure out how to use Ajax with Prototype.

As of Prototype 1.5.1
there is an easier step to post form
$(''fomID'').request({
method: ''get'',
parameters: { interests:''JavaScript'',
''hobbies[]'':[''programming'',
''music''] },
onComplete: function(){ alert(''Form data saved!'') }
})
thanks
