String Methods Overview

A method flagged as a String Method can be specified as a String containing a valid JavaScript expression. This expression will automatically be converted to a function with a return value matching the value of the last statement. Providing a String is not required - you may use a real function instead.

For example - suppose you wanted to override the leafClick() method on the TreeGrid. Normally you would do so as follows:

  TreeGrid.create({
      ...
      leafClick : function(viewer, leaf, recordNum) { 
          if(leaf.name == 'zoo') { 
              alert(1); 
          } else {
              alert(2);
          }
      }
  });
  

Since leafClick is a stringMethod, however, you can shorten this to:

  TreeGrid.create({
      ...
      leafClick : "if(leaf.name == 'zoo') { alert(1); } else { alert(2); }";
  });
