ajax

in Using jQuery • 12 years ago

I find ajax with jquery more confusing than with regular JS, b/c in jQuery you don't declare XMLHttpRequest object..   so how do you do something like

    $('#testFromAjax').append(xmlHttp.responseText);     ???
     (assuming of course that 'xmlHttp' eval's to XMLHttpRequest object)

in example I mention here,
http://forum.jquery.com/topic/ajax-php-7-3-2011-1
namely http://www.bitrepository.com/a-simple-ajax-contact-form-with-php-validation.html
I don't understand where var 'msg' is declared, I know it comes from the back-end, but HOW is it passed to the front-end??? (how do you do this w/o responseText or something similar??)

I'm trying to connect to a send-mail jsp with ajax.. the email is not getting sent.. I want to test if the ajax connection is being made at all.. don't know how do it w/o something like xmlHttp.responseText

thank you...

PS: this is my jQuery ajax code for connecting to send-email jsp:

    var dataToSend = "name=sName&email=sEmail&msg=sMsg;

         $('#submitBtn').click(function() {
    //    if (validate()) {
            $.ajax({
                type: "POST",
                url: "/mail/sendMail_ajax.jsp",
                data: dataToSend,
                success: function() {
                    Success(); //    (hides form and populates success div)
                }
            });
    //    }
    });

thank you..

thank you.. that was helpful... the guy here

http://www.bitrepository.com/a-simple-ajax-contact-form-with-php-validation.html

does not really explain how the "msg" gets passed back to the front-end.. (not the way it's explained in Stackoverlfow thread... and, just as mentioned there, the fact he names that var "msg" is not very helpful either..)

now I continue to have a problem: if I hard-code email values on the back-end (name, email, msg) email gets sent fine, but if I pull those values from the request the email does not get sent; it seems my data is not getting sent to the server... this is how I send values to the server with ajax:

var dataToSend = "name=sName&email=sEmail&msg=sMsg&pg=loc";

subBtn.click(function() {

// if (validate()) {

$.ajax({

type: "POST",

url: "/mail/sendMail_ajax2.jsp",

data: dataToSend,

success: function(xhr) {

Success();

$('#test').html(xhr);

}

});

// }

});

is this correct?

example here

http://forum.jquery.com/using-jquery is not too instructive b/c they don't assign literals to data and dataType, so I can't be sure if I did right (do I need datatype? and what are the data types??...)

here, http://api.jquery.com/jQuery.ajax/ they don't provide a post example at all...

would appreciate some help.. thank you..
