推荐答案

在Firefox等中，您需要使用scrollTo()而不是scrollBy().

In Firefox, etc. you need to use scrollTo() instead of scrollBy().

请参阅: http://jsfiddle.net/4CkML/

示例:

window.scrollTo(50,50);

如果域不匹配，则不能使用scrollTo/By.您可以在此处看到javascript错误的产生:

You cannot use scrollTo/By if the domains don't match. You can see here that a javascript error is produced:

拒绝访问属性"scrollTo"的权限

Permission denied to access property 'scrollTo'
