使用jQuery了解更多有关iframe的信息

Question

I'm using this but in some browsers I cannot get the iframe to display so I've added a function for it to be refreshed which works great.

The only problem is that this refreshes all iframe instead of just the one in the div being expanded.

<script type="text/javascript">
  $('.box').readmore({
    speed: 500,
    collapsedHeight:112,
    embedCSS: false,
    moreLink: '<a href="#" class="btn">Read more</a>',
    lessLink: '<a href="#" class="btn">Read Less</a>',
    afterToggle: function(trigger, element, expanded) {
      if( expanded) { 
        $( 'iframe' ).attr( 'src', function ( i, val ) { return val; });
      }
    }
  });
</script>

I know I could just put a class or an id on the iframe itself but this is not an option in my situation.

How can I resolve this?

Answer 1

$( 'iframe' ).attr( 'src', function ( i, val ) { return val; });
