" in textfields

[Jeff]

I'm writing innerHTML for a text field.

Sometime the textfield has double quotes in them.

value_=value_.r eplace(/"/g,'\\"');
var content = '<input type="text" name="'+name_+' " size="'+size_+' "
value="'+value_ +'">';

I'm not sure why that doesn't work, but it doesn't! I'm missing
something simple, somewhere.

Hi,

Unless you really know what you are doing, I advise you to simply use
the codes for special HTML chars.

eg:

<script type="text/javascript">
var org = "test single' and double\" endtest";
// replace "
replaced = org.replace(/\"/g,'&quot;');
// replace '
replaced = replaced.replac e(/\'/g,'&#39;');

var content = '<br><input type="text" name="bla" size="30"
value="'+replac ed+'">';

document.write( content);

</script>

You can do this with adding backslashes, but things gets complicated
very fast, especially when passing the strings around. Things get worse
when you also do this serverside.

No need to dive into that when you have &quot; and &#39; to do the work
for you.

Can't be done with backslashes; even \x22 or \u0022 are not accepted.
&quot; is the only way.

`&#x22;', `&#34;', or using other DOM mutator methods are other ways.

Hi Thomas and Bart,

When Bart wrote that it couldn't be done, I had this feeling he was wrong.
I am positive I did it earlier, I thought.
So I retried, and was unsuccesfull.
So I looked up some old code where I did it, only to find out I didn't
do it that way. :-)
I weaseled out: writing the HTML, then some JavaScript that filled the
value. :-/

Anyway, writing HTML with formelements like that is ugly IMHO.
Since all my pages are produced by PHP I seldom need document.write,
most/all can be done at the server.

The trend is the other way, not with document.write but with either
innerHTML or DOM methods.

Say we have a large table of data and you just want to edit an item
here and there. It's easier for the user if he can click on the item he
wants to edit and have that replaced with a textfield or some such and
the updates would be returned to the server in the background using
AJAX. At least that is what I was doing... simple stuff...
