如何定义cognos下拉列表的onchange事件？

xiaoerp

我定义好onchange 事件要触发的js函数脚本以后
我想在某个下拉列表中调用onchange 事件？

//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;
