    truncating include file as string problem

    I have an include file which has some text such as:

    The quick brown fox jumped over the lazy dog

    I want to have a certain amount of that text to display on one page
    wherein the user can click a link for more of the text on a new page
    such as:

    The quick brown fox >>MORE

    unfortunately, I'm having trouble making that work. Here is my code:

    <head>
    <script language="JavaS cript">
    var ln1 = "<!--#include file='incfile.i nc'-->";
    var ln2 = ln1.slice(0,20) ;
    </script>
    </head>
    <html>
    <BODY>
    <b>Latest News</b><font size=1>

    <javascript:Res ponse.write(ln2 );>
    </font><span class="morebutt on"
    onClick="locati on.href='incfil e.htm';">&gt;&g t;MORE</span>

    </BODY>
    </HTML>


    Any ideas???

    Thanks in advance!

      Is this server-side Javascript?

      You cannot include files using client-side JS.

      [ ..and the 'language="Java Script"'
      should read 'type="text/javascript"' ]

          slice() is a method of an array, not a string. You probably want
          substring() or substr():

          I have no idea what this is. It looks like a combination of server and
          client-side code, but it is mostly just wrong.

          Presumably you want:

          <script type="text/javascript">
          document.write( ln2);
          </script>

          Embedded <script ...> tags inside <font ...> tags (which you shouldn't be
          using anyway) may not work in some user agents. You'd be better off to
          use a span with a class attached.
          [color=blue]
          > </font><span class="morebutt on"
          > onClick="locati on.href='incfil e.htm';">&gt;&g t;MORE</span>[/color]

          You're using a <span> to mimic an <a> because... you don't want it to
          work if people don't have Javascript enabled in their browser? or you
          don't want it to work if their browser doesn't comprehend the onclick
          event on a <span>?

          You also don't appear to be making any decision about whether the entire
          content of ln1 was actually displayed. As a result, the MORE <span> (I
          hesitate to call it a link) appears even if ln1 consists of the word
          "Hello".

          Programming is not a hit-or-miss guessing game. You have to understand
          the concepts, understand the language you are working in, and, when
          necessary, consult the documentation to achieve the desired goal.

              It should be

              <script type="text/javascript">

              but client-side scripting only is not a reasonable solution on an Internet
              site (and sometimes not even in an Intranet). Do it server-side, with PHP,
              Perl, ASP and the like.

              > var ln2 = ln1.slice(0,20) ;[/color]

              You could write

              var ln1 = "<!--#include file='incfile.i nc'-->".slice(0, 20);

              and avoid one more global.

              > <b>Latest News</b>[/color]

              If this should be a heading, make it one:

              <h1>Latest News</h1>

              If you do not like the style, use CSS to format the element.

              What is this nonsense supposed to do? Maybe you are looking for

              document.write( ln2);

              but ... (see above/below)
              [color=blue]
              > </font>[/color]

              Do not use "font" elements anymore. They have been deprecated in
              favor of CSS with the HTML 4.01 Specification as of December 1999.

              So you already know about CSS? But obviously you do not know
              that not all users have software with support for client-side
              scripting. And those who have, have often disabled it.
              Abusing the "span" element to work like a link (a[href]) is
              foolishness. Or have you used a structure editor without
              minimum clue about HTML/CSS/J(ava)Script to "achieve" *this*?

              You should repair your Question Mark key and use

                  Font elements are in some circumstances necessary for the support of
                  less recent browsers.

                  Don't be intolerant.
