cognos8.3值提示默认值的设定

xiaoerp

实现功能说明：
1）登陆后设置提示第一个有效值为默认值；2）实现自动提交
（模拟自动提交）；3）仅能选择一个有效提示值，即选择数据项名称和‘-------’无效。
实现方法：
1）在下值提示前后各加一个html项目，
内容分别为：<span id="spanidName">
                与  </span>
注意：span id内容根据实际设置。如附件图片“值提示”。
此例中，我共有3个值提示，其中电压等级与站是级联关系，电压等级层级高于站：
<span id='spanidYear'>年份提示</span>
<span id='spanidStation'>站提示</span>
<span id='spanidVoltage'>电压等级提示</span>

2）添加一个完成按钮。（此按钮最终会被隐藏，代码控制其提交）

3）将所有提示的自动提交取消！

4）
在页面加一个html项目，内容如下：
<script. language="javascript">
//全局变量
var spanYear;
var selectYear;
var selectIndexYear;
var spanStation;
var selectStation
var selectIndexStation;
var spanVoltage;
var selectVoltage;
var selectIndexVoltage;
//获取页面值提示对象
function getSpanInfo(){
   spanYear = document.getElementById("spanidYear");//The same name as the span id.set for year prompt
   selectYear = spanYear.getElementsByTagName("select");
   selectIndexYear=selectYear[0].selectedIndex;
   spanStation = document.getElementById("spanidStation");//The same name as the span id.set for station prompt
   selectStation = spanStation.getElementsByTagName("select");
   selectIndexStation=selectStation[0].selectedIndex;
   spanVoltage = document.getElementById("spanidVoltage");//The same name as the span id.set for voltage prompt
   selectVoltage = spanVoltage.getElementsByTagName("select");
   selectIndexVoltage=selectVoltage[0].selectedIndex;
}
//初始化页面
function initOnLoad()
{
   getSpanInfo();
   if(selectIndexYear==0||selectIndexYear==1)
   { selectVoltage[0].selectedIndex=2;
     selectYear[0].selectedIndex=2;
     //selectStation[0].selectedIndex=2;

    if(getFormWarpRequest().elements["cv.id"].value=="RS")
    {
     setTimeout('oCVRS.promptAction(\'finish\')',100); //延迟一定时间很重要，否则会报错
    }else
      setTimeout('oCV_NS_.promptAction(\'finish\')',100);
   }
}
//年提示值变化（onchange事件）调用
function validateSelectYear()
{ getSpanInfo();
  if (selectIndexYear==0 || selectIndexYear==1){
      //no response
   }
  else
    {
       promptButtonFinish(); // Currently equivalent to oCV<namespace>.promptAction('finish')
    }
}
//站提示值变化（onchange事件）调用
function validateSelectStation()
{ getSpanInfo();
  if (selectIndexStation==0 || selectIndexStation==1){
      //no response
   }
  else
    {
      if(selectIndexYear ==0 || selectIndexYear ==1){
             selectYear[0].selectedIndex=2;
        }
        promptButtonFinish(); // Currently equivalent to oCV<namespace>.promptAction('finish')
    }
}
//电压等级提示值变化（onchange事件）调用
function validateSelectVoltage()
{ getSpanInfo();
  if (selectIndexVoltage==0 || selectIndexVoltage==1){
      //no response
   }
  else
    {
      if(selectIndexYear ==0 || selectIndexYear ==1){
             selectYear[0].selectedIndex=2;
        }
      if(selectIndexStation!=0 && selectIndexStation!=1){
             selectStation[0].selectedIndex=0;
        }
      promptButtonFinish(); // Currently equivalent to oCV<namespace>.promptAction('finish')
    }
}
//页面初始加载
document.forms[0].onload=initOnLoad();
var fW = (typeof getFormWarpRequest == "function" ?getFormWarpRequest() : document.forms["formWarpRequest"]);
if ( !fW || fW == undefined)   
{
     fW = ( formWarpRequest_THIS_ ?formWarpRequest_THIS_ : formWarpRequest_NS_ );
}
var buttons = fW.getElementsByTagName("BUTTON");
for (var i=0; i<buttons.length; i++)
{
if (buttons.id.indexOf('finish') == 0) // The finish button ID starts with finish. ie: id="finishN0D5D2148x0C6BEFD0_NS_"
{
    if (buttons.onclick.toString().indexOf('finish') > 0) //oCV_NS_.promptAction('finish')
    {
    //buttons.onclick = ValidatePage;
     buttons.style.display="none";
     }
  }
}
//设置onchange事件
getSpanInfo()
selectYear[0].onchange=validateSelectYear;
selectStation[0].onchange=validateSelectStation;
selectVoltage[0].onchange=validateSelectVoltage;
</script>
