javascript - HTML OnClick() 事件不起作用

Question

在我添加 document.getElementById("frame").src="https://www.youtube.com/embed/"+frm; 之前它一直在工作线 但现在即使我删除了这部分，使代码像以前一样工作正常，它仍然不起作用。我不知道为什么会这样。这可能是我现在缺少的一个小细节。找到它是什么的任何想法？

此外，我尝试加载 <p></p>来自 XML 文件的文本，但也找不到解决方法。如果有人能帮我找到正确的方法，那就太好了

function bgClicked2 (idJ,pg,frm)
{
	var id = document.getElementById("bgMAIN");
	id.src="Pics/bgCLICKED2.png";
	var id2=document.getElementById("previews");
	id2.style.visibility="visible";
	document.getElementById("planet").src="Pics/"+idJ+".png";
  document.getElementById("frame").src="https://www.youtube.com/embed/"+frm;
		
}

function bgClicked()
{
	var id,prg,frame;
	id=document.activeElement.id;
	frame=document.activeElement.name;

	bgClicked2(id,"j",frame);
	alert("ughjnj");
	loadXMLDoc();
}

Without the sun's intense energy and heat, there would be no life on Earth. And though it is special to us, there are billions of stars like our sun scattered across the Milky Way galaxy. If the sun were as tall as a typical front door, the Earth would be the size of a U.S. nickel. The temperature at the sun's core is about 27 million degrees Fahrenheit. Average diameter: 864,000 miles, about 109 times the size of the Earth.Rotation period at equator: About 27 days. Rotation period at poles: About 36 days.

这看起来像是浏览器缓存问题。尝试以隐身(私有(private))模式打开或使用“Ctrl + F5”硬刷新
