jQuery Easyui Datagrid实现单行的上移下移及保存移动的结果

function move(isUp) {
var selections = $dg.datagrid('getSelections');
if(selections.length == 0){
return;
}
var $view = $('div.datagrid-view');

var $row = $view.find('tr[datagrid-row-index=' + index + ']');

$(this).attr('id',prevId);
$(this).attr('datagrid-row-index',prevDatagridRowIndex);
prev.attr('id',thisId);
