问题说明
关于使用 setAttribute 而不是点 (.) 属性符号的最佳实践已经开发了吗?
Has a best-practice around using setAttribute instead of the dot (.) attribute notation been developed?
例如:
myObj.setAttribute("className", "nameOfClass");
myObj.setAttribute("id", "someID");
或
myObj.className = "nameOfClass";
myObj.id = "someID";

如果您想在 JavaScript 中进行编程访问，您应该始终使用直接的 .attribute 表单(但请参阅下面的 quirksmode 链接).它应该正确处理不同类型的属性(想想onload").
You should always use the direct .attribute form (but see the quirksmode link below) if you want programmatic access in JavaScript. It should handle the different types of attributes (think "onload") correctly.
Use getAttribute/setAttribute when you wish to deal with the DOM as it is (e.g. literal text only). Different browsers confuse the two. See Quirks modes: attribute (in)compatibility.
