Need help with unterminated string constant ...

[Jeff]

Hi, does anyone know why this:

<a onclick="insert atcaret(window. opener.document .formname.field name,'<td
class="header"> ')">text</a>

returns a "Unterminat ed String Constant" error message in IE 6.0 but if
I take out the double quotes around header it does not? I need double
quotes around header, I thought this was possible in javascript so long
as the pair of double quotes is surrounded by a pair of single quotes.

Does the escape character "\" around your "header" help any?

<a
onclick="insert atcaret(window. opener.document .formname.field name,'<td
class=\"header\ ">')">text</a>

Thanks for the idea, but putting an escape character ( \ ) before each
quote around header does not help in this case.

Re: Need help with unterminated string constant ...

Actually, you have double quotes surrounded by single quotes which in
turn are surrounded by double quotes. Hummm....

Quote nesting only works once. That is

" ' ' "

is fine, but

" ' " " ' "

is not. The latter is interpreted as two separate quoted strings each
containing some spaces and a single apostrophe.

The same behaviour applies to both HTML and JavaScript.

It shouldn't. The mark-up is operating under HTML's parsing rules, not
JavaScript's. When the HTML parser encounters \", it sees a backslash
followed by a double quote. When the JavaScript parser encounters it, it
sees an escaped double quote. To solve it, do what you should always do
with restricted characters in HTML: use a character entity.

<a ... onclick="[...],'<td class=&quot;hea der&quot;>')">t ext</a>

I forgot: the angle brackets are also restricted. You should use character
entities for them too.

....should be

<a ... onclick="[...],'&lt;td class=&quot;hea der&quot;&gt;') ">

That will not help as the HTML parser is not aware of javascript escape
sequences and can still see the double quote as part of the page's
source code. It will take the first pair of quotes as delimiting the
string for the onclick attribute.

Instead a javascript hex escape sequence could be used in this context
as that would still result in the double quote in the resulting
javascript string but would be meaningless to the HTML parser:-

onclick="insert atcaret(
window.opener.d ocument.formnam e.fieldname,
'<td class=\x22heade r\x22>'
);"
