getElementById with string and escaped quote problem

burfus · Jul 10, 2007

Hi,
I'm stumped on escaping a double quote when retrieving the value using
getElementById. Here is a sample where the quote is escaped but the
alert box only shows: Here is a \

<HTML>
<BODY>

<form name="testForm" action="#" method="post">
<INPUT type="hidden" id="testQuote" value="here is a \" mark">
</form>

<SCRIPT Type="text/javascript">

</SCRIPT>

</body>
</html>

Any Ideas?
TIA!

I'm stumped on escaping a double quote when retrieving the value using

<INPUT type="hidden" id="testQuote" value="here is a \" mark">

<input type="hidden" id="testQuote" value="here is a " mark">

Thanks Martin, I'll do a string replace and that will work. The
elements are populated by strings from a database where users have
used double quotes for inches. I thought I could just addslashes with
PHP and have it work OK, but the escape character isn't recognized
when javascript picks up the string from the input element.

Thanks Again.

That has nothing at all to do with JavaScript. The HTML parser when
parsing the value of the attribute named value looks for a closing quote
so if you do
value="here is a \" mark"
^ ^
then the parser finds those two quotes and consequently the value of
that attribute is "here is a \" and the remaining
mark"
is junk the parser ignores.

Or even more simple to my eyes:

<input type='hidden' id='testQuote' value='here is a " mark'>
