使用：
document.login.PMT_INDICATOR.value
或者：
document.forms [''login'']。elements [''PMT_INDICATOR'']。value
JW
Use:
document.login.PMT_INDICATOR.value
Or:
document.forms[''login''].elements[''PMT_INDICATOR''].value
JW

OTOH，您可以通过将对submitForm的调用更改为：
< input type = button name = submit1 value =" Login"
Onclick =" SubmitForm（this.form）;"
JW
OTOH, you could fix it by changing the call to submitForm into:
<input type=button name=submit1 value="Login"
Onclick="SubmitForm(this.form);">

如果（login.PMT_INDICATOR.value ==" C"）是真的，我就得不到。我做错了什么？请帮助

如果您认为某个表达式应该是真的，请不要添加警报（）
来告诉您什么价值确实如此。
在这种情况下：
alert（login.PMT_INDICATOR.value）
将告诉你价值永远不是C。
-
If an expression that you think should be true, isn''t, add an alert()
to show you what the value really is.
In this case:
alert(login.PMT_INDICATOR.value)
will show you that the value is never "C".
