当我在下面jQuery代码生成的窗口上选中“view source>frame info”时，它会在；类型=图像。我正在正确地对符号进行url编码，对吗？

Address: ...wp-admin/media-upload.php?post_id=28&type=image&

function wpe_customImages($initcontext)
{
global $post;
?>
<script type="text/javascript">
jQuery(document).ready(function() {
var fileInput = \'\';
jQuery(\'#wpe-uploadAttachments\').click(function() {
    fileInput = jQuery(this).prev(\'input\');
    formfield = jQuery(\'#upload_image\').attr(\'name\');
    post_id = jQuery(\'#post_ID\').val();
    tb_show(\'\', \'media-upload.php?post_id=\'+post_id+\'&amp;type=image&amp;TB_iframe=true&amp;wpe_idCustomAttachment=true\');
    return false;
});
