格式化输入日期时间控件 JieFormattedDateBox

格式化输入日期时间控件

可以用

JieFormattedDateBoxbox=newJieFormattedDateBox("yyyy年MM月dd日HH点mm分ss秒");

输入

也可以用

JieFormattedDateBoxbox=newJieFormattedDateBox("HH:mm:ss");

来输入时间 软件开发网

还可以这样用

JSPinnerspinner=newJSpinner();

JieFormattedDateBoxfdb=newJieFormattedDateBox(format);

spinner.setModel(fdb);

spinner.setEditor(fdb);
