如何使用JQuery获取GET和POST变量？

(function($) {
    $.urlParam = function(name) {
        var results = new RegExp('[\?&]' + name + '=([^&#]*)').exec(window.location.href);
        if (results == null) {
            return null;
        }
        return decodeURI(results[1]) || 0;
    }
})(jQuery);

var getVar = $.urlParam('your_get_variable');

$.ajax({
    type: 'POST',
    url: 'your_server_script.php',
    data: {
        post_variable: 'your_post_variable_value'
    },
    success: function(response) {
        // 在此处处理服务器响应
        console.log(response);
    }
});

<?php
    $postVar = $_POST['post_variable'];
    echo $postVar;
?>
