Jsp页面保存时的路径

fengwei_CSDN 2012-03-08 10:08:15

在一个Jsp查询页面有一个保存按钮（获取路劲）和一个确定按钮（submit），当点击保存是就弹出来一个对话框选择路径，蛮多网站都有类似的按钮......我起初用的是<input type="file" name="url" value="" />结果发现被坑爹了，这个控件只能指向一个文件，而不是文件夹。后台用的apache-poi-3.7操作的。

那个保存按钮应该怎么做，请教下高手们。

或者说我的思路根本就是错误的话，给点提示，晚辈受教了。

告警过滤处理，此处是告警计数累减
UINT32 AlarmClearJudge(UINT8* pucCount,UINT8* pucAlarmByte)
{UINT8 ucCount = y2;UINT8 ucAlarmByte = y2;CHECK;ucCount = *pucCount;
ucAlarmByte = *pucAlarmByte;if(ucCount > 0){u……

你这是什么玩意儿？
