jQuery Grid Plugin - jqGrid

Hi,

In debuging issues I was having with sorting table, I had to make some code changes. Here is a list of what I had to modify in grid.base.js:

1. grid.headers[k] is undefined in the loop in two places. I had to place a null / undefined check:
   1. Line 899: $(this).css("width",grid.headers[k].width+"px");
   2. Line 1576: $(this).css("width",self.grid.headers[k].width+"px");
2. Appending sorted row to grid was causing my Firefox to freeze, chew up tons of memory and report unruly script. The problem was happening on line 910: $('tbody',ts.grid.bDiv).append(row);. Since I am not very good with Javascript, I fixed this issue by changing line 903 onwards. Changes are as follows:
   1. Previously:
                      var cn = "";
                      if(ts.p.altRows) cn = ts.p.altclass;
                      $.each(rows, function(i, row) {
                          if(cn) {
                              if(i%2 ==1) $(row).addClass(cn);
                              else $(row).removeClass(cn);
                          }
                          $('tbody',ts.grid.bDiv).append(row); <--- This line was causing freeze
                          row.sortKey = null;
                      });
   2. Now:
                      var cn = "";
                      // Raj change
                      var sRowsText = "";
                      // End Raj change
                      if(ts.p.altRows) cn = ts.p.altclass;
                      $.each(rows, function(i, row) {
                          if(cn) {
                              if(i%2 ==1) $(row).addClass(cn);
                              else $(row).removeClass(cn);
                          }
                          // Raj change: Comment out the append
                          //$('tbody',ts.grid.bDiv).append(row);
                          var jRow = $( row );
                          sRowsText = sRowsText + "<tr id='" + jRow.attr( "id" ) + "' class='" + jRow.attr( "class" ) + "' role='" + jRow.attr( "role" ) + "'>" + jRow.html() + "</tr>";
                          // End Raj change
                          row.sortKey = null;
                      });
                     
                      // Raj change: Clear out displayed rows and append rows to inside of table
                      var dataTable = $('table',ts.grid.bDiv);
                      dataTable.children().remove();
                      dataTable.html( sRowsText );
                      // End Raj change

I hope this is useful.
