i have a variable called param, which has the value I told \"I will come\", in JSP am assigning this to a input tag's value as 

<input type="text" value="${param}"/>

what is happening is that the value am getting is I told \, i.e am getting value only till the first ", but am escaping this " with a \,but still am getting this. how can I solve this?

  • You're escaping it in the JSTL, but the generated HTML will still be `value="I told "I will come""`. You need to escape it in the HTML using the `\"`, so your JSTL variable will likely need to be: I told \\"I will come\\". – Anthony Grist Jan 07 '13 at 15:45
  • @AnthonyGrist How can I achieve that? should i do while I assign the value to variable by saying something like &quot – Seeker Jan 07 '13 at 15:48

    This is something that `fn:escapeXml()` *should* do, but I'm not sure it does. – Pointy Jan 07 '13 at 15:49

Try this:

<input type="text" value="${fn:escapeXml(param)}"/>

That will work when the escaping you need is in fact XML/HTML escaping. If you're dropping the JSTL/EL expression into JavaScript code, however, that's probably not what you want. In that case you'd want a JSON encoding function, of which there are several available I think (from Google at least). (I've got my own so I can't provide direct information.)

If you want to stick with the Core library of JSTL, this also does the trick:

<c:out value="${param}" />
