jQuery-如何获取视频src值? [英] Jquery - how i can get the video src value?

问题描述

我需要获取视频的价值，并需要更改为新的价值...为此，我使用了此功能:

i need to get the value of a video and need to change in to new value... for that i used this function:

var video = $('#task2ResultVideo').get(0);

console.log($(video).attr('poster')); // i am getting this

    $(video).attr('src',function(num,val){
        console.log(num,val)        // i am not getting this..
    }) ​

HTML:

<video id="task2ResultVideo" autobuffer poster="img/task2-results-host-poster.jpg">
    <source src="Video/webm/Task_2.4a_Host_treated.webm" type="video/webm" />
    <source src="Video/ogv/Task_2.4a_Host_treated.theora.ogv" type="video/ogg" />
    <source src="Video/MP4/Task_2.4a_Host_treated.mp4" type="video/mp4" />
</video>​

但是我无法获得这些值.我的代码有什么问题?如果我获得该值，该如何更改src?

But i am not able to get the values. what is wrong with my code? in case if i get the value how can i change the src?

有什么建议吗?
