callback中window.open后弹出文件下载框却立马消失了,网上找到的解决办法,记录下..
function exportList(txtOrExcel){
dwr.engine.setAsync(false);
ClientGroupMgmt.exportUsers(listId_exp, function(fileName) {
window.open("<%=request.getContextPath()%>/common/ftpdownloadByFileName.jsf?fileName="+fileName);
});
dwr.engine.setAsync(true);
前后加上dwr.engine.setAsync(...);
