Html 如何防止浏览器缓存表单字段？

How to prevent browser from caching form fields?

提问by Igor

I have a textboxin a form field that gets populated by the user. However currently (in Firefox 10) the user can navigate away from the page, then come back, and the input will be populated with its previous value. I think this creates for a confusing user experience, and would like to prevent it.

我有一个textbox由用户填充的表单字段。但是目前（在 Firefox 10 中）用户可以离开页面，然后返回，并且输入将填充其先前的值。我认为这会造成令人困惑的用户体验，并希望阻止它。

Is there a way to do this without manually resetting the value? I have tried changing the response to not cache as well as setting autocomplete='false'with no luck.

有没有办法在不手动重置值的情况下做到这一点？我曾尝试将响应更改为不缓存以及autocomplete='false'没有运气的设置。

<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Expires" content="-1">

or Use

或使用

<% Response.CacheControl = "no-cache"; %>
<% Response.AddHeader("Pragma", "no-cache"); %>
