问题
I've run into a really annoying problem, and I'm hoping it's just a setting I've missed. I've got an ASP.NET application which allows users to enter their username/password in various places (e.g. login, change password, change username etc..). When I logged in, the browser asked if I would like to store the user details. Usually, I click 'no', but this time I decided to click 'yes'. Now, certain textboxes in my form are prefilled with the username or password. Is it possible to remove these, as they sometimes appear in textboxes which shouldn't be prefilled. I tried setting AutoCompleteType=none and Text='' but it still gets prefilled. The textboxes don't have much in common, except the same CssClass and, for password boxes, TextMode=password. The names are different, although sometimes they include the word name (e.g. fullName, userName). Is there a way to stop the browser from filling certain textboxes?
Thanks
回答1:
<input type="text" name="Username" autocomplete="off">
You can also put this on the form tag. Note this does not work consistently in all browsers.

The only solution that worked for me was to include two fields, one for login and one for the password with display: none
<input type="text" style="display: none">
<input type="password" style="display: none">
回答3:
<asp:TextBox ID="Text1" runat="server" AutoCompleteType="Disabled"></asp:TextBox>
If you happen to work in a much more updated framework, this code should work as expected. It has been 8 years ago and some of the answers here is outdated.

if you set autocomplete="off"... the textbox will loose every words on its history... but if you want to prevent browser saved usernames and password, the best way is to put these tags in top of your page:
<input type="text" style="display: none">
<input type="password" style="display: none">
