Not getting any data from Ajax success response

Sorry, but you don't get me

It's not exactly like this

url: "/cgi-bin/isaccount.cgi?username=$name::getName()"

which would involve a method execution instead of a simple variable name

[jackvan]

I've just tested my script with your solutions:

url:"/cgi-bin/isaccount.cgi?username=" + encodeURIComponent(name.val()),

or

url:"/cgi-bin/isaccount.cgi",
data : {username: name.val()},

They don't work:

1) url:"/cgi-bin/isaccount.cgi?username=" + encodeURIComponent(name.val()),

I entered: abcd in the name field of the Form,

My Perl script, isaccount.cgi received two data: name.val() and usernameabcd immediately one after another??


2) url:"/cgi-bin/isaccount.cgi",
data : {username: name.val()},

It did not send any data to isaccount.cgi and it also seems like it did not get into the success:function(data){ loop, i.e. it is not success.

Any idea to fix it?

Please show the full code of the ajax call and the corresponding form HTML

I don't know about .cgi scripts, but in PHP the data would be available as $_GET["username"] or $_POST["username"] respectively depending on the type of request. Did you provide a type?

$.ajax({url: "...",
type: "GET",
data: {username: ...},
...
});

Correction:

The first method works with some a minor problem:

url:"/cgi-bin/isaccount.cgi?username=" + encodeURIComponent(name.val()),

When I entered: reggy

I got: usernamereggy without an equal "=" between, i.e. I should be getting: username=reggy

Any idea to fix it?

Obviously your .cgi is reading the values differently than usual. Try this

url:"/cgi-bin/isaccount.cgi?" + encodeURIComponent(name.val()),

No, I did not use type in the Ajax loop. That was the problem.

After I insert: type: "GET", I'm getting proper data:

username=john
username=jack
username=peggy

etc

Sorry for the confusion.

I've one other problem. Here's the code:

PHP Code:

    //On blur
    name.blur(validateName);
    email.blur(validateEmail);
    pass1.blur(validatePass1);
    pass2.blur(validatePass2);
    //On key press
    name.keyup(validateName);
    name.keyup(validateName);
    pass1.keyup(validatePass1);
    pass2.keyup(validatePass2);
    message.keyup(validateMessage);

    function validateName(){
        //if it's NOT valid
        if(name.val().length < 4){
            name.addClass("error");
            nameInfo.text("We want names with more than 3 letters!");
            nameInfo.addClass("error");
            return false;
        }
        //if it's valid
        else{
                    $.ajax({
                    
                    url:"/cgi-bin/isaccount3.cgi?username=" + encodeURIComponent(name.val()),
                    type: "GET",
                    
                    async:false,
                    success:function(data){

                        name.removeClass("error");
                        nameInfo.removeClass("error");

                        if(data=="yes"){
                            nameInfo.text("name ok");
                            nameInfo.removeClass("error");
                        }
                        if(data=="no") {
                            nameInfo.text("Name In Use");
                        }
                        return true;
                        }

                    
                });

            return true;
        }
    } 


The user is required to enter a username with a minimum 4 characters, if it is valid than it will check the availability of the username.

Here's the problem. When I enter username longer than 4 characters, e.g. "peggy", I may get 2 data: "username=pegg" and "username=peggy".

Any idea to fix it?

I've fixed the problem by changing keyup() to focus():

PHP Code:

    //On focus 
    name.focus(validateName); 
    name.focus(validateName); 
    pass1.focus(validatePass1); 
    pass2.focus(validatePass2); 
    message.focus(validateMessage); 


I've learned a lot from you. My Form Validation is working wonderfully. Thanks again for your time.
