动态打印功能

您好， 您的表单中是不是有用到我们的用户选择框。在平台中用户选择框是获取到用户的主键。如果您需要获取用户名可以在定义一个隐藏字段，根据用户选择框获取的id通过下面这段脚本获取用户名。
var userProcess = createProcess("cn.myapps.core.user.ejb.UserProcess");
    var user = userProcess.doView(getItemValueAsString("用户选择框名称"));
    var name =user.getName();//获取用户名称

是写到隐藏脚本里面吗！？
  似乎是不行啊！

   是这样写吗！？？？

不是。我的意思是再添加一个字段去获取用户名。打印时隐藏脚本只能设置你当前这个字段在打印时是否隐藏。我写的那段脚本是在那个添加字段的值脚本里谢的。

额。。。您先需要去判断字段是否为空。因为刚进入页面我们没有选择用户。所以直接用getItemValueAsString("用户选择框名称")会报错。
var name ="";
if(getItemValue("用户选择框名称")!=null && getItemValue("用户选择框名称")!="" ){
var userProcess = createProcess("cn.myapps.core.user.ejb.UserProcess");
    var user = userProcess.doView(getItemValueAsString("用户选择框名称"));
    name =user.getName();//获取用户名称
}
name;
