问题
I am fairly new in this. I have the following iframe
<iframe width="560" height="315" src="<%=video1[1]%>" frameborder="0" allowfullscreen></iframe>
What I am trying to do is have it play video1[1], but show the image that is in video1[2].
I tried doing is:
<iframe width="560" height="315" href="<%=video1[2]%>" src="<%=video1[1]%>" frameborder="0" allowfullscreen></iframe>
but that doesn't work.
Is there a simple way of doing it?
回答1:
iFrame tag has no href attribute.
See: http://www.w3schools.com/tags/tag_iframe.asp
You could maybe build an iFrame which acts as a target for a link:
<iframe width="560" height="315" src="<%=video1[1]%>" frameborder="0" allowfullscreen> name="iframe_video1"></iframe>
<a href="<%=video1[2]%>" target="iframe_video1"><img src="<...>"></a>
BTW: Pay attention that in an iFrame's source attribute, there has to be a document (i.e. web page) referenced, no media/video directly. You could use YouTube links e.g. to be embedded....
