php - ajax GET 无法使用 jtable 将数据发送到 php 页面

Question

我正在使用 jtable 来显示数据以便于访问。

在这里，我的问题是 php 页面无法获取 $data 值，因此我无法检索查询的数据。 它总是进入 else 案例，不知道为什么!!

我很努力，但没有一个想法是成功的。感谢您的帮助。

尝试: jquery:

 $.post('EMPActions.php',{

                data = {qstr: $('input#qstring').val()}
                },
                function(response) {
                    $('#EmployeeContainer').jtable('load');
                    //$('#EmployeeContainer').html(response);
                },"json");

PHP

if(isset($_POST['qstr'])){
$data = '%'.$_POST['qstr'].'%';
}
else{
$data = '%';
}
