    Maybe you can use string replace function.

    In php this would be
    $variable = str_replace("x", "y", $variable);
    PHP:
    Not sure if this works with single or double quotes though - it changes character x to character y in the string $variable

    Hi,

    I wouldn't have thought you would have a problem.

    Here is a short code snippet showing how to put a string with quotes into a text box.

    <html>
    <input  id="txtMyVal"  value="This is the start value" style='width:200px'>
    
    <script>
    var sTest="'this is a test'";
    
    document.getElementById("txtMyVal").value = sTest;
    </script>
    </html>
    Code (markup):
    Do you have an example which shows your problem?

    If your server-side code (PHP, ASP, etc) generates JS code, you need to escape quotes and slashes, so that the resulting string would look like this:

    var str = "double quote: \"; single quote: \'; slash: \/;";

    You can use any string replace function for this. If your server-side code generates HTML (e.g. a form element), you need HTML-encode double quotes, single quotes and the <> characters. For example the result will be:

    <input name="i1" value="double quote: &quot;; single quote: &#x27;; less than: &lt;; greater than: &gt;;">

    If you use PHP, use htmlspecialhars, if ASP, use Server.HTMLEncode to encode.
