Javascript jQuery验证,滚动到error donds';我不能正常工作
因此,我有一个3阶段的表单,在每个步骤进行验证,然后在提交时再次进行验证。我有一些问题,我想这可能是由于我的JS的结构,但我不能确定 出于某种原因,它只会滚动到第一个错误一次,一旦有人填写字段时清除了该错误,它就会滚动到页面顶部。尽管事实上,我们现在可以翻开新的一页了。我已经复制了所有相关的代码,并且去掉了很多JS,因为有大约300行。如果您希望看到其“xxxx”的工作副本,我有一个实时url 这里是JSJavascript jQuery验证,滚动到error donds';我不能正常工作,javascript,jquery,jquery-validate,scrolltop,Javascript,Jquery,Jquery Validate,Scrolltop,因此,我有一个3阶段的表单,在每个步骤进行验证,然后在提交时再次进行验证。我有一些问题,我想这可能是由于我的JS的结构,但我不能确定 出于某种原因,它只会滚动到第一个错误一次,一旦有人填写字段时清除了该错误,它就会滚动到页面顶部。尽管事实上,我们现在可以翻开新的一页了。我已经复制了所有相关的代码,并且去掉了很多JS,因为有大约300行。如果您希望看到其“xxxx”的工作副本,我有一个实时url 这里是JS var form = $("#msform"); form.validate({

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。非常感谢您抽出时间阅读此文章。请查看IP地址以获取表单对验证的反应的工作副本
非常感谢您抽出时间阅读此文章
编辑:已删除实时链接,因为问题已得到回答。<代码>$('html,body')。动画({
scrollTop:($('.error:visible').offset().top-60)
}, 500);
您的选择器将与所有错误类匹配,无论是否显示。在您的例子中,animate函数获取列表中的第一个匹配项
添加“:visible”时,您只选择了页面上显示的元素。我怎么会错过这个??在所有的谷歌搜索中,我找到了解决我问题的方法,但没有人使用:可见。非常感谢!与“实时链接”不同,您应该包括相关的HTML以及类似JSFIDLE演示的内容。毕竟,SO的目的是为未来的读者保留这些问答。你的这些缺失对他们的帮助要小得多。
