使用php中创建的变量从PHP调用Javascript函数

Question

I have a javascript function in a file comment_insert.js:

  function comment_insert(data,ul_id) {

        var t = '';
        t += '<li class="comment-holder" id="_' + data.comment_id + '">';
        t += '<div class="user-img">';
        t += '<img src="' + data.profile_img + '" class="user-img-pic" />';
        t += '</div>';
        t += '<div class="comment-body">';
        t += '<h3 class="username-field" >' + data.Username + '</h3>';
        t += '<div class="comment-text">' + data.comment + '</div>';
        t += '</div>';
        t += '<div class="comment-buttons-holder">';
        t += '<ul>';
        t += '<li class="delete-btn">[x]</li>';
        t += '</ul>';
        t += '</div>';
        t += '</li>';

        $('#' + ul_id).prepend(t);
    }

I want to call this function from a php file display.php as:

$smthng = new stdClass();
        $smthng->comment_id = 24;
        $smthng->Userid = 1;
        $smthng->comment = "Hard coded comments";
        $smthng->Username = "Sagar_username"; 
        //$smthng->profile_img = "images/Setting-icon.png";


        $data =  json_encode($smthng);
                $ul_id = "ul218";

 comment_insert(jQuery.parseJSON($data),$ul_id);

The function being called is the same as in comment_insert.js which accepts 2 inputs (data and ul_id). These are being created in display.php and then I want to execute the function.

Assuming that the PHP code is in the same file as Javascript and is being used for front end out put to the browser, you can do this:

<?php
$smthng = new stdClass();
        $smthng->comment_id = 24;
        $smthng->Userid = 1;
        $smthng->comment = "Hard coded comments";
        $smthng->Username = "Sagar_username"; 
        //$smthng->profile_img = "images/Setting-icon.png";


        $data =  json_encode($smthng);
                $ul_id = "ul218";
?>
<script type="text/javascript">
    comment_insert(jQuery.parseJSON(<?php echo $data ?>), <?php echo $ul_id ?>);
</script>

However, if this is not in a file that is producing output to the browser, you cannot execute Javascript server-side
