我想获得一个值返回到PHP，我可以工作，并发送到数据库。我似乎不能够是使用jQuery AJAX的GET类型的事情。下面是我使用捕捉值PHP：

I'm trying to get a value back to PHP which I can work with and send to the database. I don't seem to be able to do that using the GET type of jQuery AJAX. Here's the PHP I'm using to catch the value:

<?php require_once("header.php"); ?>
<?php require_once("class.php"); ?>
<?php

//$month = $_POST['month'];
//$year = $_POST['year'];

$month = 8;
$year = 2013;
$numDays = cal_days_in_month(CAL_GREGORIAN, $month, $year);
$empty = "<table class='box'><td>&nbsp</td></table>";

$cal = new calendar();
$cal->mkMonth($month);
$cal->emptyDays($empty, $numDays, $month, $year);
$cal->mkdays($numDays, $month, $year);

echo "</div>";


echo "<div id='jresult'>";
if (isset($_GET['id'])) {
   echo ($_GET['id']);
}

echo "</div>";
?>

下面是jQuery的...

Here's the jQuery...

$(document).ready(function(){
    $(".box").mouseenter(function(){$(this).css("background-color", "red");});
    $(".box").mouseout(function(){$(this).css("background-color", "transparent");});
    $(".box").click(function() {
        date_time = $(this).attr('id');
        console.log(date_time);
        $.ajax({
            type: 'GET',
            url: '/book.me/loop.php',
            data: "id=" + $(date_time).val(),
            success: function(data){
                alert('successful');
            }
        });
    });
});

我想传递的的ID .bo​​x的类元素的 DATE_TIME 变量，它的工作原理，但它似乎并不当我打电话 $ _ GET ['身份证'] 在PHP是工作。我刚开始处于不确定的状态回来了。

I'm trying to pass in the id of the .box class element to the date_time variable which works, but it doesn't seem to be working when I call $_GET['id'] in PHP. I'm just getting an undefined value back.

推荐答案

如果您要发送的id属性，而不是价值，你可以用

If you want to send the id attribute, not the value, you can use

$(".box").click(function() {
    date_time = $(this).attr('id');
    $.ajax({
        type: 'GET',
        url: '/book.me/loop.php',
        data: "id=" + date_time,
        success: function(data){
            alert('successful');
        }
    });
});
