How do you dynamically change a video that is playing using the action tag?

12 лет назад • обновлен 12 лет назад • 3

I've got an app that checks weather conditions (using Yahoo weather RSS feed) for a user entered zip code (or WOEID). Everything works great, but when I send a new video file request to the tag in my code, it just keeps playing the original video that I sen it. Do I have to do anything special to stop or unload the old video before the new one will play?

Here's the and sample code:

... (first time through, I play this video, and it appears just fine)

... (second time through, I try to play this video, but the original just keeps playing)

Can you wrap your examples in a < code > block so I can see them?

Try assigning the code value as a variable first and then using that in your if statement queries.

For example:




<assign property="var:code" value="[datasource:RSSFeed.*[local-name()='condition']/@code]" /> 



<if lhs="[var:code]" operator="e" rhs="02"> 


<videocontrol type="play" file="video/Gillham.mp4" target="VID-FRAME" /> 


</if> 


<if lhs="[var:code]" operator="e" rhs="03"> 


<videocontrol type="play" file="video/CrownCenter.mp4" target="VID-FRAME" /> 


</if>
