//grid.sortBy("price", "desc");
var win = mini.get("win1");
function orderClick(action, id)

win.set({

grid.on("drawcell", function (e) {
var record = e.record,
column = e.column,
field = e.field,
value = e.value;
if (field == "handle") {
e.cellStyle = "text-align:center";
e.cellHtml = '<a href="javascript:orderClick(\'edit\', \'' + record.id + '\')">修改</a>  ';
e.cellHtml += '<a href="javascript:orderClick(\'view\', \'' + record.id + '\')">详细</a>  ';
