the text method doesn't work in my js file.

// JavaScript Document

  // appending div to the body //


      var $para = $("<p></p>");

     var $image = $("<img>");

      var $overlay = $("<div id='overlay'></div>");





      //                 AdDiNg OvErLaY aNd iMaGe WiTh TeXt             //




      $image.append($para);

      $overlay.append($image);

     $("body").append($overlay);


     // iMaGe CliCk FuNcTiOn ShOwInG oVeRlAy            //


      $(".pic-nav li a").click( function(e) {

           e.preventDefault();

           var loc = $(this).attr("href");

             var captionTex = $(this).attr("alt"); 

            $image.attr("src", loc);

             $para.text(captionTex);


            $overlay.show();

     });

         $image.click( function() {

             $overlay.hide(); 

         });

            ``` js



          this is the whole file.. for the beginning of making a interactive photo album.

An image can not have children, this is why your paragraph does not appear.

If you want to have an image with a caption, you should use reproduce this kind of markup :

<figure>
    <img src='image.jpg' alt='alt text' />
    <figcaption>Here goes the caption</figcaption>
</figure>

which will translate to :

var $fig = ($("<figure></figure>");
var $image = $("<img>");
var $caption = $("<figcaption></figcaption>");

$fig.append($image);
$fig.append($caption);

Hope this helps
