It's simple, just do this:
很简单，只要这样做：
btn.on("click", function(){
var src = "new_video_src.mp4";
$("#video").find("#tv_main_channel").attr("src", src)
})

To dynamically load videos you need to run
要动态加载视频，您需要运行
var video_block = $('#video');
video_block.load();
Then you should also see a change in the display too, and not only in the html.
然后你也应该看到显示的变化，而不仅仅是在 html 中。

You can use like this in click event
您可以在点击事件中像这样使用
var src = "new_video_src.mp4";
$("#tv_main_channel").src=src;
This is the actual method for video tag elements
这是视频标签元素的实际方法
