Question

大家好我有一个PHP文件和这段代码：

<?php echo "Hello World"; ?>
<script type="text/javascript">
    $(document).on('click', '.order-submit', function() {
        dataName = $(this).data('name');
        var company = <?php echo json_encode(get_Comp( /* dataName here */)); ?>;
    });
</script>

如何传递javascript变量＆＃34; dataName＆＃34;到我的PHP功能＆＃34; get_Comp＆＃34;？如果有人帮忙，我会很高兴。谢谢！

Answer 1

这是不可能的，你需要使用ajax来实现这个目标：

PHP getcomp.php

<?php
   //put here your get_Comp() function

   $dataName = $_POST['dataName'];
   echo json_encode(get_Comp($dataName));
?>

<强> JAVASCRIPT

<?php echo "Hello World"; ?>
<script type="text/javascript">
    $(document).on('click', '.order-submit', function() {
        dataName = $(this).data('name');
        var company;
        $.post('getcomp.php', {dataName: dataName}, function(data) {
            company = data; //company should be equal to json_encode(get_Comp($dataName));
        });
    });
</script>

Answer 2

PHP代码在服务器端呈现，而JavaScript在客户端呈现。因此，您无法将JS变量传递给PHP函数。

您可以做的是，您可以使用dataName向您的PHP服务器发出AJAX请求以获取信息。
