這篇文章主要介紹了擴展datagrid的一個方法keyCtr實現鍵盤上下控制選中行,需要的朋友可以參考下
擴展datagrid的一個方法keyCtr 代碼如下: $.extend($.fn.datagrid.methods, { keyCtr : function (jq) { return jq.each(function () { var grid = $(this); grid.datagrid('getPanel').panel('panel').attr('tabindex', 1).bind('keydown', function (e) { switch (e.keyCode) { case 38: // up var selected = grid.datagrid('getSelected'); if (selected) { var index = grid.datagrid('getRowIndex', selected); grid.datagrid('selectRow', index - 1); } else { var rows = grid.datagrid('getRows'); grid.datagrid('selectRow', rows.length - 1); } break; case 40: // down var selected = grid.datagrid('getSelected'); if (selected) { var index = grid.datagrid('getRowIndex', selected); grid.datagrid('selectRow', index + 1); } else { grid.datagrid('selectRow', 0); } break; } }); }); } });
