警报？？？？ [英] Alert????
问题描述
你好，
我试图在javascript中找出警报的功能。我
的表格大约有5个字段。每个字段都检查输入的
信息是否有效。如果用户输入了无效的
信息，则会弹出一个警告框。我的问题是，如果我在
警告框中说好，整个页面都会刷新。是否有任何方式
仅该特定字段（输入无效信息）
是否刷新，其余字段是否如此？
提前致谢。
酒窝。
Hello,
I am trying to figure out the functionality of alert in javascript. I
have a form with about 5 fields. Each field has a check on whether the
information entered is valid. If the user enters an invalid
information, a alert box pops up. My problem is, if I say OK on the
alert box, the entire page is refreshed. Is there any way in which
only that particular field (in which invalid information is entered)
is refreshed and the remaining fields are as they were?
Thanks in advance.
Dimple.

如果没有代码，我只能猜测问题。
我的第一个猜测是没有从事件中返回false处理程序。
也就是说，警报往往是一种尴尬和烦人的处理条目的方式
错误，特别是如果逐个字段地完成。
Without code, I can only guess as to the issue.
My first guess is not returning false from an event handler.
That said, Alert tends to be an awkward and annoying way to handle entry
errors, ESPECIALLY if done on a field-by-field basis.

是和否。
是可能的，否则不会被称为刷新。
如果不显示你的代码，讨论就没有意义了。
请只显示必要部分。

Yes and no.
Yes it is possible and No that would not be called refresh.
The discussion however is meaningless without you showing your code.
Please only show the essential part.

否，在你的javascript中。
