试图通过JQuery Ajax将特殊字符发送到PHP脚本

Question

I'm sending special characters to a PHP file via JQuery Ajax.

send_to_process.js

var special_charac = '!@#$%^&*()_+-=';
var dataString = 'data=' + special_charac;

$.ajax({
                type: "POST",
                url: "./process.php",
                data: dataString,
                cache: false,

                success: function (result) {

                }
            });

process.php

<?php

$data= $_POST['data'];
echo $data;

?>

In the PHP file I'm getting all values except + and &

Why is it so ?

Does JQuery Ajax has got some limitations as to what data can you send to PHP script ?

Answer 1

These are not AJAX limitations. These are URL limitations. eg & is used to split parameters. Just send data as json object

not:

data: dataString,

but

data: {data: special_charac}

or use encodeURI function to escape data

var dataString = 'data=' + encodeURI(special_charac);
