How can jQuery be used to adjust the width and height of an iframe?

After researching a solution on a website, I attempted to implement it but encountered issues. It seems like there may be another script dictating the styling, so I need to add some code directly to the page to override it.

This is what I tried:

<script type="text/javascript">
    $(document).ready(function () {
        $("#frame1").width(578);
        $("#frame1").height(326);
    });
</script>

Despite my efforts, the rendered HTML continues to display the following:

<iframe frameborder="0" src="http://player.vimeo.com/video/20657168?color=fc030f" style="width: 500px; height: 281.25px;"></iframe>

I am aiming for the width to be 578 and the height to be 326. You can find the website at this link:

P.S. When attempting to add a class or ID, it gets removed from the HTML due to the platform being used (Tumblr).

Answer №1

If you want to ensure it functions properly, just include id="frame1" in your iframe tag.

<iframe frameborder="0" id="frame1" src="http://player.vimeo.com/video/20657168?color=fc030f" style="width: 500px; height: 281.25px;"></iframe>

By using the jQuery selector $("#frame1"), you can target the element with the specified id attribute frame1. For more details, check out: jQuery Selectors and ID Selector.

Note: If the ID is being removed, adjust how the selector works and apply it to all iframes instead:

<script type="text/javascript">
    $(document).ready(function () {
        $("iframe").width(678);
        $("iframe").height(526);
    });
</script>

In case there are multiple iframes on the page that require different sizes, utilize the :eq(index) selector to specify which iframe to modify based on its position. For example, for the second iframe:

<script type="text/javascript">
    $(document).ready(function () {
        $("iframe:eq(1)").width(678);
        $("iframe:eq(1)").height(526);
    });
</script>

Make iframe responsive to window size

<iframe frameborder="0" src="http://player.vimeo.com/video/20657168?color=fc030f" style="width: 500px; height: 281.25px;"></iframe>

<script>
    $(document).ready(function(){
       $("iframe").height($(window).height());
       $("iframe").width($(window).width());

       $( window ).resize(function() {
            $("iframe").height($(window).height());
            $("iframe").width($(window).width());
        });
    });
  </script>
