how i define my controller :
def show
@user=User.find(params[:id])
respond_to do |format|
format.json { render json: @user.to_json, :only => [:name,
:email]}
end
end
how i define my ajax function:
function FunAjax()
{
$.ajax({
type: "POST",
url: "http://ip:3000/users/1.json",
data: "begin=1&end=9",
dataType: "json",
timeout : ''50000'',
error : function(){
alert (''server error'');
},
beforeSend: function(){
$("#span_content").text("processing...");
},
success:function(data){
if(data === null){
alert(''no data'');
}else{
var div_cont ="";
$.each(data,function(idx,arr_item){
div_cont = div_cont
+"<br/>key："+idx+"value："+
arr_item;
}),
$("#span_content").html(div_cont);
}
}
});
};
$(document).ready(function () {
alert(''start'');
});
then i browse the url:http://ip:3000/users/1.json
it will return a string like this:
{"name":"fang","email":"fang-UQ28/Rtelqk@public.gmane.org"}
but the ajax function won`t work.
please tell me how can i exchange data between the server and the browser?

What''s in your log? in your JavaScript console? And why are you POSTing a request to a method that typically would be accessed via GET, as in your browser (which apparently works)? -- Hassan Schroeder ------------------------ hassan.schroeder-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org http://about.me/hassanschroeder twitter: @hassan -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
