javascript - 为什么CVS要扩展javascript调用？

Question

为什么 CVS 扩展下面的 SetDropdownList 调用

来自

SetDropdownList('BillPay', 'BillingState', '$State$');

至

SetDropdownList('BillPay', 'BillingState', '$State: Exp $');

在下面的 JavaScript 中？

我应该将 html 文件转换为二进制文件吗？

我已尝试以下步骤来调查此问题。我将 html 文件(其中包含 javascript 函数)复制到一个安全的地方；删除了该文件；输入CVS删除命令删除CVS元素；然后使用 add 和 commit 从保存的副本重新创建 CVS 元素。

尽管如此，SetDropdownList 仍然如上所示展开。

function EnterPage()
{
var ElemID;

// Set the payment type and credit card radio buttons to their correct initial
// state (ACH payment, credit card choice 0).
SetRadioButton('BillPay', 'PaymentTypeID', 1);
SetRadioButton('BillPay', 'CCTypeID', 0);

// Make the credit card fields invisible.  ACH is the default.
if (document.all && !document.getElementById) ElemID = document.all['CCTable'];
else ElemID = document.getElementById('CCTable');

ElemID.style.display = 'none';

// Fill in the various fields of the form that we know about.  Note that we use
// double quotes, in case there are any apostrophes in the names.
document.forms['BillPay'].elements['ACHNameOnAccount'].value = "$FullName$";
document.forms['BillPay'].elements['CCNameOnCard'].value = "$FullName$";
document.forms['BillPay'].elements['BillingAddress1'].value = "$Address1$";
document.forms['BillPay'].elements['BillingAddress2'].value = "$Address2$";
document.forms['BillPay'].elements['BillingCity'].value = "$City$";
SetDropdownList('BillPay', 'BillingState', '$State$');
document.forms['BillPay'].elements['BillingZipcode'].value = "$Zipcode$";
document.forms['BillPay'].elements['Location'].value = "$Location$";
document.forms['BillPay'].elements['AcctType'].value = "$AcctType$";
document.forms['BillPay'].elements['BillYear'].value = "$BillYear$";
document.forms['BillPay'].elements['AcctNum'].value = "$AcctNum$";
document.forms['BillPay'].elements['BillAmount'].value = "$AmountPaid$";
document.forms['BillPay'].elements['ScholarAmount'].value = "$ScholarAmt$";
document.forms['BillPay'].elements['AmountPaid'].value = "$TotalAmt$";

// Make the scholarship donation visible, if there is one.
if (document.all && !document.getElementById)
  ElemID = document.all['ScholarDonat'];
else ElemID = document.getElementById('ScholarDonat');

if ('$ScholarAmt$' != '0.00') ElemID.style.visibility = 'visible';

// The page is set up.
return;
}

$State 是 CVS 关键字，请参阅 http://csg.sph.umich.edu/docs/unix/cvs/cvsref-card.html和 https://www.cs.utah.edu/dept/old/texinfo/cvs/cvs_16.html

“默认情况下，CVS 会执行关键字扩展，除非您告诉它停止。当您将文件添加到项目中时，您可以使用 -k 选项永久抑制文件的关键字扩展”，请参阅 http://durak.org/sean/pubs/software/cvsbook/Controlling-Keyword-Expansion.html

它给出的用于抑制关键字扩展的命令行示例是:

$ cvs add -ko chapter-9.sgml

如果您使用 TortoiseCVS，我不知道有什么建议，大概他们有类似的选项来控制关键字扩展
