The information in this article applies to:
- Microsoft Internet Explorer (Programming) 5

This article was previously published under Q244397 SYMPTOMS
In some situations, such as the scenario described under "Steps to Reproduce Behavior" in the "More Information" section of this article, strings can be unexpectedly terminated when some part of the string is the result of a prompt() dialog that had double-byte character set (DBCS) characters entered into it.
This only applies to the Japanese versions of Windows 95 and Windows 98.
RESOLUTIONWorkaround:
To work around this problem, create your own prompt dialog, Prompt.htm. (Note that you will have to change the charset based on the language that you are targeting.)
<HTML>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=x-sjis">
<TITLE>HTML Sample</TITLE>
<SCRIPT LANGUAGE="JavaScript">
function SbmtF()
{
window.returnValue=document.InputForm.UserName.value;
window.close();
}
</SCRIPT>
<BODY>
<FORM NAME="InputForm">
<INPUT TYPE="text" NAME="UserName">
<INPUT TYPE="button" NAME="btnSubmit" value="OK" onClick="SbmtF();">
</FORM>
</BODY>
</HTML>
The following is an example of how the preceding page can be used:
<HTML>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=x-sjis">
<TITLE>HTML Sample</TITLE>
<Script Language="JavaScript">
function btnConstant()
{
Title1 = ", ";
strLink = Title1 + ">>Added String<<";
document.FM1.Text1.value = strLink;
}
function btnAddLink_onclick()
{
Title1 = showModalDialog("prompt.htm");
strLink = Title1 + ">>Added String<<";
document.FM1.Text2.value = strLink;
}
</Script>
<BODY>
<FORM name=FM1>
<INPUT type="Text" size=80 value="" id=Text1 name=TextBox1>
<INPUT type="button" value="Constant" id=btnAddLink name=btnAddLnk onClick=btnConstant()><P>
<INPUT type="Text" size=80 value="" id=Text2 name=TextBox2>
<INPUT type="button" value="Prompt" id=btnAddLink name=btnAddLnk onClick=btnAddLink_onclick()><P>
</FORM>
</BODY>
</HTML>
