javascript - Send form data with jquery ajax json

asked Oct 24, 2021 in Technique[技术] by 深蓝 (71.8m points)

I'm new in PHP/jquery I would like to ask how to send json data from a form field like (name, age, etc) with ajax in a json format. Sadly I can't found any relevant information about this it's even possible to do it dynamically? Google searches only gives back answers like build up the data manually. like: name: X Y, age: 32, and so on.

Is there anyway to do that?

Thanks for the help!

Edit:

<form action="test.php" method="post">
Name: <input type="text" name="name"><br>
Age: <input type="text" name="email"><br>
FavColor: <input type="text" name="favc"><br>
<input type="submit">
</form>

here is a simple one

here is my test.php for testing only

<?php

// this is just a test
//send back to the ajax request the request

echo json_encode($_POST);

here is my index.html

<!DOCTYPE html>
<html>

<head>

</head>
<body>

<form id="form" action="" method="post">
Name: <input type="text" name="name"><br>
Age: <input type="text" name="email"><br>
FavColor: <input type="text" name="favc"><br>
<input id="submit" type="button" name="submit" value="submit">
</form>




<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script>
    $(document).ready(function(){
        // click on button submit
        $("#submit").on('click', function(){
            // send ajax
            $.ajax({
                url: 'test.php', // url where to submit the request
                type : "POST", // type of action POST || GET
                dataType : 'json', // data type
                data : $("#form").serialize(), // post data || get data
                success : function(result) {
                    // you can see the result from the console
                    // tab of the developer tools
                    console.log(result);
                },
                error: function(xhr, resp, text) {
                    console.log(xhr, resp, text);
                }
            })
        });
    });

</script>
</body>
</html>
