带iframe的jquery对话框

Question

I'm trying to use the jquery ui dialog box to output an iframe. It doesn't seem to be working for me. I think I am making a syntax mistake somewhere- probably with quotation marks in the iframe. Any help would be much appreciated.

<a href='' onclick=\"open_course_article('$userid','$title', 'remove', '$sel_course');\">Remove from Course</a>

   function open_course_article(userid,article,option,course) {
        $('<iframe src="article_course.php?option="+option+"&userid="+userid+"&course="+course+"&article="+escape(article)"/>').dialog({
        title: 'Add Article',
        width: 600,
        height: 400,
        modal: true,
        }).width(570).height(370);
     }

Answer 1

You are mixing single quotes with double quotes for enclosing a string , which does not work in programming.

$('<iframe src="article_course.php?option="+option+"&userid="+userid+"&course="+course+"&article="+escape(article)"
 />')

should be something more like:

$('<iframe src="article_course.php?option='+option+'&userid='+userid+'&course='+course+'&article='+escape(article)+'"
 />')

The jquery selector you have specified is wrong. I believe you have an tag somewhere in your html. Select iframe this way

  $('iframe').dialog{ ...}

or if you have other iframes in your html then you will have to provide some unique attribute...lets say id in which case:

   $('iframe #idvalue').dialog{ ...}

please show your html file for us to be able to help better
