Javascript and variable scope

I have the need to create a two dimensional array to collect values in my jsp. In order to populate the 2-d array I'm using code like this

 <script language="JavaScript">
     var row = 0;
     var multiDimenArray = new Array();
 </script>
 <c:forEach var="items" items="${item}" varStatus="status">
      ............
      <script language="JavaScript">
          multiDimenArray [row] = new Array();
          var column = 0;
          row++;
     </script>
     <c:forEach var="nestedItems" items="${nestedItem}" varStatus="status">
        ............
           <script language="JavaScript">
                multiDimenArray [row][column] = "some value";
                column++;
           </script>

However in the third script blo开发者_运维问答ck when i attempt to assign the value i get a JS error saying that the variable row is undefined. Is it possible to pass variables between script blocks like this in JS?

You are getting that because you are incrementing row before the third script runs.

So when you try to run multiDimenArray [row][column] = "some value"; row actually equals 1 instead of 0.

You need to move the row++ to after the column is assigned.
