Javascript在添加一行代码时崩溃

好的，这是我的javascript。 当我将变量angle1添加到javascript中时，会使整个javascript崩溃。基本上我想要的是，jhin的图像会在鼠标上方旋转。当鼠标离开jhin时，它会旋转回到原来的位置。（看不见）

css:

应该是

var angle1 = document.getElementById('jhin');

---

var angle1=90 document.getElementById（'jhin'）请仔细检查。
var angle1=90 document.getElementById（'jhin'）检查它。你忘了放
之后
var angle1=90
