自动登录 [英] Auto login
问题描述
我正在用他公司的网站帮助这个人。他们有一个页面，你登录的页面是
，基本上看起来当你输入密码和
用户信息并提交表格时，它会运行一个javascript函数来保存
将信息作为cookie。它看起来像这样：
< script language =" JavaScript">
function savecookie（）
{
/ *保存表格输入的用户和密码值
（document.form.elementname）在cookie中* /
var url =" /sap/its/iacproject/select_premises.html" ;;
var nextyear = new Date（）;
nextyear.setFullYear（nextyear.getFullYear（）+ 1 ）;
document.cookie =''password =''+ document.Login.password.value +
''＃expires =''+ nextyear.toGMTString（） + ''; path = /'';
document.cookie =''user =''+ document.Login.user.value +'';
expires =''+ nextyear .toGMTString（）+'';路径= /'';
}
< / script>
他们希望这样做，以便在您注册时，一个不同的
页面，你可以自动登录。我尝试通过将saveCookie函数复制到注册的最后一页
$ b $来实现这一点。 b处理，并相应地改变变量。这是因为在注册表中有很多SAP，所以它可以获得
fishy。这是来自注册页面的我的
savecookie功能：
< script language =" JavaScript">
函数savecookie（）
{
/ *保存cookie中输入表单的用户和密码值
* /
var url =" /sap/its/iacproject/select_premises.html" ;;
var nextyear = new Date（）;
nextyear.setFullYear （nextyear.getFullYear（）+ 1）;
document.cookie =''password =
EWEBIAC_HTML_LOGIN_FIELDS-alias_name_RES.value; path = /'';
document.cookie =''user =
EWEBIAC_HTML_LOGIN_FIELDS-PASS_RES.value; expires =''+
nextyear.toGMTString（）+'';路径= /'';
}
savecookie（）;
< / script>
现在，它几乎正常运作。它确实为我保存了cookie，但
值都搞砸了。我认为在为cookie变量分配
时出现语法错误。我希望它只是一些引号或
这里有人能为我识别的东西。我分配变量
是因为SAP看起来如下：
< body`SAP_BodyAttributes（）`onLoad ="`SAP_OnLoadJavaScript（） `">
`SAP_TemplateFormBegin（）`
< h2 style =" font-style：arial" style =" font-size：24pt">`#l_header`< / h2>
`SAP_TemplateGroupBoxBegin（groupboxlabel =＃success）`
`SAP_TemplateInfoLine（~messlineline）`
< br>
`SAP_TemplateNonEditableField（" alias_name_RES"，
fieldLabel = fieldLabel =＃alias_name，
fieldLabelWidth =" 250"，value = EWEBIAC_HTML_LOGIN_FIE LDS-alias_name_RES.value，size =" 150"）`
< br>
`SAP_TemplateNonEditableField（" PASS_RES"，
fieldLabel = EWEBIAC_HTML_LOGIN_FIELDS-PASS_RES.label，
fieldLabelWidth =" 250"，value = EWEBIAC_HTML_LOGIN_FIE LDS-PASS_RES.value，size =" 20"）`
< br>
`SAP_TemplateNonEditableField（" smtp"，
fieldLabel = EWEBIAC_HTML_LOGIN_FIELDS-smtp.label，
fieldLabelWidth =" 250，value = EWEBIAC_HTML_LOGIN_FIE LDS-smtp.value，size =&quo t; 100"
< script language =" JavaScript">
savecookie（）;
< ; / script>
.....
< snip>
任何人都知道我怎么能得到变量从
之前的表单传递到cookie中？谢谢！

你在拖钓。

废话。 `passwd''只需要转义如果它包含一个
`;''因为这已经是cookie值组件分隔符;
a simple passwd.replace（" ;"，"％3B"）就足够了。

Hey gang,
I''m helping this guy with his company''s website. They have a page where
you login, and basically it looks like when you enter your password and
user info and submit the form, it runs a javascript function that saves
the info as a cookie. It looks like this:
<script language="JavaScript">
function savecookie()
{
/* save the values of user and password of the form input
(document.form.elementname) in the cookie */
var url = "/sap/its/iacproject/select_premises.html";
var nextyear = new Date();
nextyear.setFullYear(nextyear.getFullYear() + 1);
document.cookie = ''password= ''+ document.Login.password.value +
''# expires=''+ nextyear.toGMTString() +''; path= /'';
document.cookie = ''user= ''+ document.Login.user.value + '';
expires='' + nextyear.toGMTString() +''; path= /'';
}
</script>
They want to make it so that when you register, which is on a different
page, you can automatically be logged in. I tried doing this by copying
the saveCookie function into the final page of the registeration
process, and changing the variables accordingly. This is where it gets
fishy, because there''s a lot of SAP in the registration form. Here''s my
savecookie function from the registration page:
<script language="JavaScript">
function savecookie()
{
/* save the values of user and password of the form input in the cookie
*/
var url = "/sap/its/iacproject/select_premises.html";
var nextyear = new Date();
nextyear.setFullYear(nextyear.getFullYear() + 1);
document.cookie = ''password=
EWEBIAC_HTML_LOGIN_FIELDS-alias_name_RES.value; path= /'';
document.cookie = ''user=
EWEBIAC_HTML_LOGIN_FIELDS-PASS_RES.value; expires='' +
nextyear.toGMTString() +''; path= /'';
}
savecookie();
</script>
Now, it''s almost working. It does save the cookie for me, but the
values are all messed up. I think I have a syntax error in assigning
the cookie variables. I''m hoping it''s just a few quotation marks or
something that someone here can identify for me. I assign the variables
like this because of how the SAP looks below:
<body `SAP_BodyAttributes()` onLoad="`SAP_OnLoadJavaScript()`">
`SAP_TemplateFormBegin()`
<h2 style="font-style:arial" style="font-size:24pt">`#l_header`</h2>
`SAP_TemplateGroupBoxBegin( groupboxlabel=#success)`
`SAP_TemplateInfoLine(~messageline)`
<br>
`SAP_TemplateNonEditableField("alias_name_RES",
fieldLabel=fieldLabel=#alias_name,
fieldLabelWidth="250",value=EWEBIAC_HTML_LOGIN_FIE LDS-alias_name_RES.value,size="150")`
<br>
`SAP_TemplateNonEditableField("PASS_RES",
fieldLabel=EWEBIAC_HTML_LOGIN_FIELDS-PASS_RES.label,
fieldLabelWidth="250",value=EWEBIAC_HTML_LOGIN_FIE LDS-PASS_RES.value,size="20")`
<br>
`SAP_TemplateNonEditableField("smtp",
fieldLabel=EWEBIAC_HTML_LOGIN_FIELDS-smtp.label,
fieldLabelWidth="250",value=EWEBIAC_HTML_LOGIN_FIE LDS-smtp.value,size="100")`
<script language="JavaScript">
savecookie();
</script>
.....
<snip>
anyone have an idea of how I can get the variables passed from the
previous form into the cookie? Thanks!
<11**********************@f14g2000cwb.googlegroups .com>
var passwd = document.forms[''MyFormName''].
elements[''EWEBIAC_HTML_LOGIN_FIELDS-alias_name_RES''].value;
// JavaScript doesn''t resolve variables inside strings, it''s not Perl
here :-)
// And what an ugly name with *minus* in it which is always a call for
troubles :-(
// But it''s your solution anyway...
document.cookie = ''password='' + escape(passwd) +''; path= /'';
// cookie values need to be escaped (es well as cookie names
// if you use some strange chars in it which is not a case here)
And so on with other cookies...

Thank you friend, and if this works, I''ll put those comments in there
just for fun :)

You are trolling.
[...]
document.cookie = ''password='' + escape(passwd) +''; path= /'';

Nonsense. `passwd'' only needs to be escaped if it contained a
`;'' as this is already the cookie value component delimiter;
a simple passwd.replace(";", "%3B") suffices.
