所以我有一个3阶段表格,在每一步验证,并在提交时再次验证。我有一些问题,我认为这可能是由于我的JS的结构,但我不能确定。
由于某种原因,它只会滚动到第一个错误一次,一旦有人填写该字段时清除该错误,它就会滚动到页面顶部。尽管我们现在可以在一个新的页面上。我已经复制了所有相关代码,并删除了大部分JS,因为有大约300行。如果您希望查看工作副本,我确实有一个实时网址' xxxx'
这是JS;

我知道那里有很多代码,但我认为这可能是一个结构性问题。非常感谢您花时间阅读本文。请参阅IP地址以获取表单如何对验证做出反应的工作副本。

答案 0 :(得分:2)
$('html, body').animate({
scrollTop: ($('.error:visible').offset().top - 60)
}, 500);
您的选择器与所有错误类匹配,尽管显示或没有。在您的情况下,animate函数获取列表中第一个匹配的项目。
当您添加":可见"您只选择了页面上显示的元素。
