EasyUI edatagrid 实现回车键结束编辑功能

onDblClickCell : function(index, field, value) {
 if (opts.editing) {
  $(this).edatagrid('editRow', index);
  focusEditor(field);
  //以下是我添加的代码
  var currentEdatagrid = $(this);
  $('.datagrid-editable .textbox,.datagrid-editable .datagrid-editable-input,.datagrid-editable .textbox-text').bind('keydown', function(e){
       var code = e.keyCode || e.which;
       if(code == 13){
       $(currentEdatagrid).datagrid('acceptChanges');
       $(currentEdatagrid).datagrid('endEdit', index);
       }
    });
  //添加代码结束
 }
 if (opts.onDblClickCell) {
  opts.onDblClickCell.call(target, index, field,value);
 }
},
