Struts2 jquery datepicker将0或null值传递给action类 [英] Struts2 jquery datepicker passing 0 or null value to action class

问题描述

我是新来的struts。我正在使用jquery datepicker插件。我想从用户那里获取日期（和时间）并将其插入到数据库中。当我提交表单时，如果我将数据类型设置为long（或int），则操作类接收0值，并且当我将数据类型设置为其他任何东西时，它接收到null。我不知道应该使用什么数据类型以及如何完成。请帮助

JSP表单

  < s：form name =register-complaintaction =registerComplaintmethod =post> 
：
：
< sj：datepicker id =date_timename ='date_and_time'label =违规的日期和时间
 timepicker =truetimepickerAaPm = truetimepickerGridHour =1timepickerGridMinute =5
 timepickerStepMinute =5/> 
：
：
< / s：form> 
  

动作类

  private Date dateAndTimeOfOccurance; 
 //或long 
 
 public String execute throws异常{
：
 ps.setDate（13，（java.sql.Date）getDateAndTimeOfOccurance（））; 
 //或ps.setLong（13，getDateAndTimeOfOccurance（））; 
：
} 
  

解决方案

名称属性错误。因为你的变量是

  private Date dateAndTimeOfOccurance; 
  

您需要在JSP中写：

 < sj：datepicker name =dateAndTimeOfOccurance
 id =date_time
 label =违规的日期和时间
 timepicker = $
 timepickerAaPm =true
 timepickerGridHour =1
 timepickerGridMinute =5
 timepickerStepMinute =5/> 
  

显然要记住在Action中为该变量生成一个Getter和Setter。

I'm new to struts. I'm using jquery datepicker plugin. I want to get a date(and time) from the user and insert it into the database. When i submit the form, the action class receives 0 value if i set the datatype to long(or int) and it receives null when i set datatype to anything else. I'm not sure what datatype should be used and how it is to be done. Please help

JSP form

<s:form name="register-complaint" action="registerComplaint" method="post">
  :
  :
<sj:datepicker id="date_time" name='date_and_time' label="Date and Time of Offence"         
timepicker="true" timepickerAaPm="true" timepickerGridHour="1" timepickerGridMinute="5"             
timepickerStepMinute="5"/>
:
:
</s:form>

Action class

private Date dateAndTimeOfOccurance;
// or long

public String execute throws Exception{
  :
   ps.setDate(13, (java.sql.Date) getDateAndTimeOfOccurance());
   // or       ps.setLong(13, getDateAndTimeOfOccurance());
  :
}

解决方案

Your name attribute is wrong. Since your variable is

private Date dateAndTimeOfOccurance;

you need to write that in JSP:

    <sj:datepicker name = "dateAndTimeOfOccurance" 
                     id = "date_time"  
                  label = "Date and Time of Offence"         
             timepicker = "true" 
         timepickerAaPm = "true" 
     timepickerGridHour = "1" 
   timepickerGridMinute = "5"             
   timepickerStepMinute = "5"/>

Obviously remember to generate a Getter and a Setter for that variable in the Action.
