我在jQuery中获得了社交书签，但如何在这段代码中获得帖子标题和永久链接？如果我把<?php echo get_permalink(); ?> 在那里，整个网站都是空白的。

$(\'a[rel=shareit-twitter]\').attr(\'href\', \'http://twitter.com/home?status=\' + title + \'%20-%20\' + title);

以下是书签的整个jQuery：

<script type="text/javascript">
   jQuery(
    function() {
         //grab all the anchor tag with rel set to shareit
    $(\'a[rel=shareit], #shareit-box\').click(function(e) {      
         e.preventDefault();
        //get the height, top and calculate the left value for the sharebox
        var height = $(this).height();
        var top = $(this).offset().top;

        //get the left and find the center value
        var left = $(this).offset().left + ($(this).width() /2) - ($(\'#shareit-box\').width() / 2);     

        //grab the href value and explode the bar symbol to grab the url and title
        //the content should be in this format url|title
        var value = $(this).attr(\'href\').split(\'|\');

        //assign the value to variables and encode it to url friendly
        var field = value[0];
        var url = encodeURIComponent(value[0]);
        var title = encodeURIComponent(value[1]);

        //assign the height for the header, so that the link is cover
        $(\'#shareit-header\').height(height);

        //display the box
        $(\'#shareit-box\').show();

        //set the position, the box should appear under the link and centered
        $(\'#shareit-box\').css({\'top\':top, \'left\':left});

        //assign the url to the textfield
        $(\'#shareit-field\').val(field);

        //make the bookmark media open in new tab/window
        $(\'a.shareit-sm\').attr(\'target\',\'_blank\');

        //Setup the bookmark media url and title
        $(\'a[rel=shareit-mail]\').attr(\'href\', \'http://mailto:?subject=\' + title);
        $(\'a[rel=shareit-facebook]\').attr(\'href\', \'http://www.facebook.com/share.php?u=\' + url + \'&title=\' + title);
        $(\'a[rel=shareit-posterous]\').attr(\'href\', \'http://posterous.com/share?linkto=\' + url + \'&title=\' + title);
        $(\'a[rel=shareit-twitter]\').attr(\'href\', \'http://twitter.com/home?status=\' + title + \'%20-%20\' + title);
    });

    //onmouse out hide the shareit box
    $(\'#shareit-box\').mouseleave(function () {
        $(\'#shareit-field\').val(\'\');
        $(this).hide();
    });

    //hightlight the textfield on click event
    $(\'#shareit-field\').click(function () {
        $(this).select();
    });
});
  </script>
