这就是全部代码→

<script>
            jQuery.noConflict();
            jQuery(document).ready(function()
                {

                    jQuery(\'#mailchimp_submit-<?php echo $random?>\').click(function()
                    {
                        jQuery(\'#process-<?php echo $random?>\').css(\'display\',\'block\');
                        var datastring = \'&name=\' + escape(jQuery(\'#name-<?php echo $random?>\').val()) + \'&email=\' + escape(jQuery(\'#email-<?php echo $random?>\').val()) + \'&api_key=<?php echo $mailchimp_api_key;?>&list_id=<?php echo $mailchimp_list_id;?>\';
                        jQuery.ajax({
                            url: \'<?php echo rest_url(\'/chimp/rest/process_chimp/\');?>\',
                            data: datastring,
                            success: function(msg)
                            {
                                jQuery(\'#process-<?php echo $random?>\').css(\'display\',\'none\');
                                jQuery(\'#newsletter_msg-<?php echo $random?>\').html(msg);
                            },
                            error: function(msg)
                            {
                                jQuery(\'#process-<?php echo $random?>\').css(\'display\',\'none\');
                                jQuery(\'#newsletter_msg-<?php echo $random?>\').html(msg);
                            }
                        });
                        return false;
                    });
            });
        </script>

有很多困惑：

1个→

如何处理此问题，因为它有分号→

jQuery.noConflict();

我应该这样做吗：

$output = \'jQuery.noConflict();\'; 或

$output = \'jQuery.noConflict()\'; 或

$output = \'jQuery.noConflict();\'

2→

如何处理具有功能的→

jQuery(document).ready(function()

像这样→

$output =  \'jQuery(document).ready(function()\';

如何处理此问题→

4→

jQuery.ajax({
              url: \'<?php echo rest_url(\'/chimp/rest/process_chimp/\');?>\',
              data: datastring,
              success: function(msg)
              {

5→

return false;

以上内容是否也需要修改？

请指导我哪里做错了，哪里的方法和理解不正确。This is an Extension of this old question.

以上所有代码都是我试图转换为短代码的小部件的一部分。

function wpse_279827_shortcode() {
    // Do PHP stuff.
    $message = \'Hello world!\';
    // Start capturing output.
    ob_start(); 
    // Close PHP tags and start outputting HTML.
    ?>

    <div>
        <h1>HTML can go here</h1>
        <p>And also php code:</p>
        <p><?php echo \'Hello!\'; ?></p>
    </div>
    <script>
        jQuery(document).ready(function() {
            alert(\'Message variable from PHP: <?php echo $message; ?>\');
        });
    </script>

    <?php
    // Reopen PHP tags and return captured output.
    return ob_get_clean(); 
}
add_shortcode( \'wpse_279827_shortcode\', \'wpse_279827_shortcode\' );
