javascript - extracting src and paste before in html link with jquery

Question

I'm trying to extract the src of an img and then paste the src into a "a href" to wrap around the original img

I have two versions that I've messed with and can't get either to work. I think one of my problems seems to be inserting an "a href" before or around an element.

<script type="text/javascript">
  var x = hdnImg.children('img').attr('src') 

  $( "img" ).wrap(function() {
  return "<a href='" +x+ "' class="anyclass"></a>";
    });
</script>

or

<script type="text/javascript">
  var p = hdnImg.children('img').attr('src')

  $( "img" ).before( "<a href='#' class="anyclass">" );
  $( "img" ).after( "</a>" );
</script>

ultimately, this is was I'm trying to go for:

html before script:

    <img src="http://a.jpg">
    <img src="http://b.jpg">

html after script

    <a hre="http://a.jpg" class="classy"><img src="http://a.jpg"></a>
    <a hre="http://b.jpg" class="classy"><img src="http://b.jpg"></a>

I'm still learning javascript and could use a little guidance. Thanks

Answer 4

<div class="images">
   <span><img src="http://a.jpg"></span>
   <span><img src="http://b.jpg"></span>
</div>

使用以下脚本：

 $(document).ready(function () {
        $('.images img').each(function () {

            var link = "<a href='" + $(this).attr("src") + "'>" + $(this).closest('span').html() + "</a>";
            $(this).closest('span').html(link);
        });
    });

也许这可以帮助你。

$("img").addClass("classy");
$("img").html('<img src="http://b.jpg">');
