Question

是否可以将$ data变量发送到url：section中的jquery脚本以从不同的php文件获取源代码？（新手程序员）。我需要能够做这样的事情，例如：

var source =
            {
                 datatype: "json",
                 datafields: [
                     { name: 'timeserver', type: 'time'},
                     { name: 'val1', type: 'number'},

                ],

                url: '<?php echo $data; ?>.php',

                cache: false
            };

Answer 1

如果是关于那部分的话：

url: '<?php echo $data; ?>.php'

是的，这是可能的。

Answer 2

var data = "<?php echo data; ?>";

以上一行放在PHP模板/ View / Controller

中

在jQuery中的用法：

url : data + '.php'

Answer 3

其他答案可能有效，但它们不是正确的方法。

正确的方法是使用json_encode。

var data = <?php echo json_encode($data) ?>;

请注意，php语句周围没有引号。 json_encode将专门为javascript转义字符，并且它可以正确处理不同类型和空变量。

<强>实施例：

<?php
    $str = "Hello World";
    $nothing = null;
    $arr = ['apple', 'orange', 'banana'];
    $user = array(
        'name' => 'Rob',
        'age' => 42,
        'admin' => true,
    );
?>

<script type="text/javascript">
    var str = <?php echo json_encode($str) ?>,
        nothing = <?php echo json_encode($nothing) ?>,
        arr = <?php echo json_encode($arr) ?>,
        user = <?php echo json_encode($user) ?>;
</script>



// Results in all valid javascript variables
var str = "Hello World",
    nothing = null,
    arr = ["apple","orange","banana"],
    user = {"name":"Rob","age":42,"admin":true};

JQUERY - 存储php变量并在jquery脚本中回显它？
