    Multiline

    Hi there.

    This is a simple one I think but I couldn't find anything in my HTML or JavaScript reference books.

    How do I write JavaScript programming code over more than one line. That is, how do I break it up?

    With Visual FoxPro, for example, I would use +; like follows:

    COPY FIELDS NAME, AGE, ADDRESS, GROUP, INCOME, +;
    OCCUPATION, STATUS TO TEMPORARY_TABLE

    How do I do likewise with a long JavaScript line of code?

    Thanks.

    Russell.

    you just need to use the Enter key:

    if (condition1 &&
    condition2 ||
    condition3)
    {

    }

      Glenn.

      Thanks for your email but my code doesn't work using enter.

      I have the following code:

      <html>
      <body>
      <script language="javascript">
      var boy="Johnny"
      var girl="Mary"
      document.write("<table><tr><td><b><h2>"+boy+"</h2></b></td></tr><tr><td><b><h3>"+girl+"</h3></b></td></tr></table>" )
      </script>
      </body>
      </html>

      Whilst I keep the document.write on one long line in my text editor everything renders ok, but if I break the line by entering at any point then it doesn't work.

      I'd like to break the line up so I can see my code more clearly in order to maintain it, but I can't work out how to do that.

      Russell.

        Try This

        <html>
        <body>
        <script language="javascript">
        var boy="Johnny"
        var girl="Mary"
        var outputText = "<table><tr><td><b><h2>"+"
        outputText = outputText + "boy+"</h2></b></td></tr><tr>"
        outputText = outputText + "><td><b><h3>"+girl+"</h3></b>"
        outputText = outputText + "</td></tr></table>"
        document.write(outputText)
        </script>
        </body>
        </html>

        I didn't test this, but That is how u create a query in an ASP.

        PS I think you would be better to leave the text on one line, just for simplicity sake. What i have done above, introduces 4 lines for those damm bugs to crawl in but do as u please

          you just can't break at any point as you said.
          you only break before or after an operator.
          you can't break inside a string literal, if the string literal is too long, you can split it into many separate literals.

          you would do it like this:

          document.write("<table><tr><td><b><h2>"+
          boy+
          "</h2></b></td></tr>"+
          "<tr><td><b><h3>"+
          girl+
          "</h3></b></td></tr></table>" )

            Breaking up lines

            Thanks pastor and glenn.

            Both of those methods work nicely.
