下拉列表修改后在页面的显示

时间:2022-04-24 19:27:12
我的项目是hibernate,spring,struts1.2

在添加页面中有三个下拉列表,刚添加时候是正常的,当我修改的时候只允许修改一个下拉列表,修改后显示的时候,其他的下拉列表都变成初始值了!

关于下拉列表的初始值我是在po中写的,还有就是自己写了一个类 来放下拉列表的值!

po中的内容是:public String getCustTypeDesc( ) {
    
     try {
     switch (Integer.parseInt(this.custType.trim())) {
     case 0: 
         return new String("非签约用户");
     case 1:
         return new String("签约用户");
     default:
        return new String("非签约用户");
    
     }
     } catch (Exception exp) {
    return new String("非签约用户");
     }
    
    }
    public String getCertTypeDesc( ) {
    
     try {
     switch (Integer.parseInt(this.certType.trim())) {
     case 0: 
         return new String("身份证");
     case 1:
         return new String("军官证");
     case 2:
         return new String("护照");
     case 3:
         return new String("其他");
     default:
        return new String("身份证");
    
     }
     } catch (Exception exp) {
    return new String("身份证");
     }
    
    }
    public String getStateDesc( ) {
    
     try {
     switch (Integer.parseInt(this.state.trim())) {
     case 0: 
         return new String("正常");
     case 1:
         return new String("冻结");
     case 2:
         return new String("其他");
     default:
        return new String("正常");
    
     }
     } catch (Exception exp) {
    return new String("正常");
     }
    
    }
    public String getSexDesc( ) {
    
     try {
     switch (Integer.parseInt(this.sex.trim())) {
     case 0: 
         return new String("男");
     case 1:
         return new String("女");
     default:
        return new String("男");
    
     }
     } catch (Exception exp) {
    return new String("男");
     }
    
    }

这是自己的写的类:
public int doStartTag() throws JspException {    
HttpServletRequest request = (HttpServletRequest)pageContext.getRequest();
JspWriter out = pageContext.getOut(); 
                if (id.compareToIgnoreCase("pcustomercusttype") == 0)
listCustType(out);
else if (id.compareToIgnoreCase("pcustomercerttype") == 0)
listCertType(out);
else if (id.compareToIgnoreCase("pcustomersex") == 0)
listSex(out);
else if (id.compareToIgnoreCase("pcustomerstate") == 0)
listState(out);

              //这是其中的一个方法 
              private void listCustType(JspWriter out) throws JspException {

try {
if ( enable == false )
out.println("<select class='text' name='custType' disabled >");
else
out.println("<select class='text' name='custType'>");

if ( value == 0 ) 
out.println("<option value='0' selected >非签约用户</option>");
else
out.println("<option value='0'>非签约用户</option>");

if ( value == 1 )
out.println("<option value='1' selected >签约用户</option>");
else
out.println("<option value='1'>签约用户</option>");

if ( value != 1 && value != 0)
out.println("<option value='2' selected >所有用户</option>");
else
out.println("<option value='2'>所有用户</option>");


out.println("</select>");
} catch (java.io.IOException e) {
throw new JspTagException(e.getMessage());
}

我试了,是得不到值,这样在修改完之后 相应设置为disable 的值,在显示的时候都是null

action里得到null了 你就别更新这个下拉选的值了啊

#8


我按照你说的写了javascript,但是还是不行,因为我初始值都是0.非签约用户。我找个了签约用户来修改,改完之后保存,就又变初始值了!

#9


你在action里 得到了哪个下拉选的值就更新哪个,你看看你更新的时候是否输出了正确的sql语句,可能是你没更新对

#10


我把action改成:
 /*
* 对数据进行修改的回显
*/
public ActionForward detail(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)throws Exception {

String custid=request.getParameter("custId");
try{
PCustomer pc= pcustomerserviceimpl.findBycustId(custid);
request.setAttribute("pc", pc);
}catch(Exception exp){
exp.printStackTrace();
}

    return mapping.findForward("pcustomer_detail");
}

   /*
* 对数据进行修改
*/
public ActionForward update(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)throws Exception {
PCustomerForm cf = (PCustomerForm) form;
try{
PCustomer data = this.pcustomerserviceimpl.findBycustId(cf.getCustId());
data.setState(cf.getState());
pcustomerserviceimpl.update(data);
}catch(Exception exp){
exp.printStackTrace();
}
return browser(mapping,form,request,response);
}

PCustomer data = this.pcustomerserviceimpl.findBycustId(cf.getCustId()); 
//在得到以后判断下是否是空的,你现在这样得到了如果是空的 

data.setState(cf.getState());
pcustomerserviceimpl.update(data); //你在这更新就把原来有的类型弄成空的了,所以你显示的时候全为0了,明白了吧

应该怎么写?

是判断cf.getCustId()是否是空的哈,上面没写清楚

PCustomer data = this.pcustomerserviceimpl.findBycustId(cf.getCustId()); 
//在得到以后判断下是否是空的,你现在这样得到了如果是空的 

data.setState(cf.getState());
pcustomerserviceimpl.update(data); //你在这更新就把原来有的类型弄成空的了,所以你显示的时候全为0了,明白了吧

#12


应该怎么写?

#13


是判断cf.getCustId()是否是空的哈,上面没写清楚

#14


问题已经解决!
