Alternate text for iframes

We have alternate text, alt attribute, for an img tag in HTML, which will show up when the image doesn't come up. I tried using the tag with iframe too.

<iframe src="www.abc.com" alt="Web site is not avaialable">

But the alternate text doesn't come up when src="" is given. Just wanted to know if I can achieve alternate text in any other way, if the src is not given ?

Solution

  • Since my first attempt misunderstood your question, let's try this instead:

    <script>
$(function () {

    $("iframe").not(":has([src])").each(function () {

    var ifrm = this;

    ifrm = (ifrm.contentWindow) ? ifrm.contentWindow : (ifrm.contentDocument.document) ? ifrm.contentDocument.document : ifrm.contentDocument;

    ifrm.document.open();
    ifrm.document.write($(this).attr("alt"));
    ifrm.document.close();

    });

});
</script>

    This will read the "alt" tag value for any iframe with either no src attribute or a src attribute with a blank value, and write the alt text into the body of that iframe.
