Does javascript forbid changing the input type from password or to password?

问题

I am using this code on the input element:

onmouseout="
$('#passwordhelp').text('');
$('#rpassword').attr('type', 'password')"

回答1:

You can't change the property type with jquery in the way you are attempting to do it. You're bumping into a browser issue:

See JQuery change type of input field

回答2:

Are you using jQuery 1.6 or above? If so try .prop(). In your case like this (Example):

onmouseout="
$('#passwordhelp').text('');
$('#rpassword').prop('type', 'password')"

Though it won't work on IE8 and below.

IMHO you shouldn't use javascript and jQuery like this. Bind your events on .ready(). But of course it's your choice...
