    passing variables?

    I have a statement such as this:

    <body onmousedown="Ja vaScript:var x = :xlocCur();">

    This xlocCur returns a number, integer.

    then in the body I have:

    <script type="text/javascript">
    alert(x)
    </script>

    x is undefined. How can I pass values between JavaScript islands?

      "JavaScript :" above is supposed to be used as a URI specifier, not to
      determine the language of intrinsic events. To do this, declare the
      default scripting language with the following META element placed in
      the document head:

      <META http-equiv="Content-Script-Type" content="text/javascript">

      The above intrinsic event can (and /should/) be written as:

      <BODY onmousedown="va r x = xlocCur()">
      [color=blue]
      > This xlocCur returns a number, integer.

      You should qualify that call properly (window.alert).
      [color=blue]
      > </script>
      >

      Three options:

      1) Don't define the variable with the var keyword. That should place
      it in global, rather than local, scope.

      2) Define the variable (with or without var) in a script block
      outside of a function (so it becomes global). Then simply assign to
      it as normal.

      3) Use a function for the intrinsic event.

      function myEventHandler( ) {
      window.alert( xlocCur() );
      }

          Hmm thanks Michael. I found a way around it:

          <a onmousedown="Ja vaScript:var x = :xlocCur(); function(x);">

          But I like yours better.
