【问题描述】：
我正在尝试处理 sessionScope 变量，但在下一页上没有立即识别它们。抱歉这里有很多信息，但有什么想法吗？
第一个 XCpage 有一个名为 ccMultipleLoadHandlers 的 customControl。在自定义控件中有一个重复控件，它获取 Domino 视图中数据的句柄，最后一列是一个链接，它设置了几个 sessionScope 变量并打开另一个 XPage。这是链接的代码。
<xp:link
escape="true"
id="link3"
text="${langBean.labelEdit}"
value="/RemanRental.xsp">
<xp:this.onclick><![CDATA[#{javascript:sessionScope.calitm=""}]]></xp:this.onclick>
<xp:eventHandler
event="onclick"
submit="true"
refreshMode="norefresh">
<xp:this.action><![CDATA[#{javascript:importPackage(com.mycorpname);
dBar.info("Entering Link for ccRentMultLoadHandView")
try{
var doc
var calitm
var caitm
sessionScope.rentDisplay = "MultLoadHandDisplay";
var hostURL = configBean.getValue("HostURL")
var hostName = configBean.getValue("HostCommon")
var dbName = configBean.getValue("rentalDbPath")
var webPath = configBean.getValue("WebsiteURL")
try{
//var rtn
var urlPath = hostURL+webPath
dBar.info("urlPath: "+urlPath)
if(rowData.isDocument()){
dBar.error("rowData is Document");
doc = rowData.getDocument();
if (doc != null){
calitm = doc.getItemValue("CALITM");
modelNbr = calitm[0];
dBar.error("1. modelNbr="+modelNbr);
modelNbr =modelNbr.slice(2);
dBar.error("2. modelNbr="+modelNbr);
sessionScope.calitm = modelNbr;
dBar.error("CALITM IS "+sessionScope.calitm)
caitm = doc.getItemValue("CAITM");
sessionScope.caitm = caitm[0];
dBar.error("ccRentMultLoadHandView >>>> CAITM IS "+sessionScope.caitm)
var fam = doc.getItemValue("family");
sessionScope.family=fam[0];
var strURL = urlPath+"/Rental.xsp?"
dBar.info("Returning: "+urlPath+"/Rental.xsp?databaseName="+hostName+"!!"+dbName+"&documentId="+rowData.getUniversalID()+"&action=openDocument");
sessionScope.urlPath = urlPath+"/RemanRental.xsp?databaseName="+hostName+"!!"+dbName+"&documentId="+rowData.getUniversalID()+"&action=openDocument"
return urlPath+"/Rental.xsp?databaseName="+hostName+"!!"+dbName+"&documentId="+rowData.getUniversalID()+"&action=openDocument"
} else {
dBar.info("Unable to get handle on document");
}
}
} catch (e) {
dBar.info("1. ccRentMultLoadHandView >> link error >>>Unable to get handle on document. " + e.toString());
println("1. ccRentMultLoadHandView >> link error>>>> " + e.toString());
return e.toString()
}
} catch (e) {
dBar.info("2. ccRentMultLoadHandView >> link try error >> Unable to get handle on document. " + e.toString());
println("2. ccRentMultLoadHandView >> link try error>>>> " + e.toString());
return e.toString()
}}]]></xp:this.action>
</xp:eventHandler>
</xp:link>
打开的 XPage 有一个名为 ccRentMultLoadHandleDisplay 的自定义控件，它在 afterPageLoad 事件中有代码。该代码是：
importPackage(com.mycorpname);
dBar.error(">>>> sessionScope.rentDisplay is "+sessionScope.rentDisplay+" <<<<")
if (sessionScope.rentDisplay=="MultLoadHandDisplay"){
try{
// ***** Get RENTAL Specs ****
var table = configBean.JdbcTable_03;
sessionScope.jdbcTable = table;
dBar.error("ccRentMultLoadHandDisplay>>>sessionScope.rentDisplay = "+sessionScope.rentDisplay);
var caitm = sessionScope.caitm;
dBar.info("ccCartonlampDisplay>>var caitm is: "+caitm);
var calitm = sessionScope.calitm;
dBar.info("ccCartonlampDisplay>>var calitm is: "+calitm);
getComponent("modelNbr").setValue(calitm);
dBar.warn("rentBean.getMultLoadHandData("+caitm+","+sessionScope.Region+","+ table+","+ sessionScope.family+")")
var returnMap=new com.ibm.jscript.std.ObjectObject();
returnMap = rentBean.getMultLoadHandData(caitm,sessionScope.Region, table, sessionScope.family);
dBar.info( "Got Rental Specs");
var i;
var rmc //return map component
var value
//dBar.info("return map size: " + returnArray.size());
sessionScope.returnArray=true
//dBar.info("returnArray.getCACLLB()= "+returnArray.getCACLLB());
// we will now set the values not set above. what they gets set to depends on values set in othe fields above
dBar.error("ccRentMultLoadHandDisplay>>>Entering CartonClampDisplay data");
for ( i in returnMap ){
dBar.warn("ccRentMultLoadHandDisplay>>>i = "+i.toUpperCase());
rmc = i.toUpperCase();
var value = returnMap[i];
value = Number(returnMap[i])/100;
//dBar.warn("RemanRental>>>value = "+value);
var fieldVal;
switch(rmc.trim()){
case "CAACMT":
fieldVal = String(returnMap[i]);
dBar.warn("ccRentMultLoadHandDisplay>>>String(value) CAACMT = "+fieldVal);
getComponent(rmc.trim()).setValue(fieldVal);
break;
case "CAMFCL":
fieldVal = String(returnMap[i]);
dBar.warn("ccRentMultLoadHandDisplay>>>String(value) CAMFCL = "+fieldVal);
getComponent(rmc.trim()).setValue(fieldVal);
dBar.warn(rmc.trim()+": "+getComponent(rmc.trim()).getValue());
break;
default:
dBar.warn("ccRentMultLoadHandDisplay>>>value = "+value);
getComponent(rmc.trim()).setValue(value);
dBar.warn(rmc.trim()+": "+getComponent(rmc.trim()).getValue());
break;
}
}
} catch(e){
println("There was an error in ccRentCartonDisplay afterPageLoaad");
dBar.error("ccRentMultLoadHandDisplay---->Error in afterPageLoad: "+ e.toString());
println("ccRentMultLoadHandDisplay-----> Error in afterPageLoad: "+ e.toString());
}
}
问题是 sessionScope 变量为空，但如果我重新加载页面，它们就在那里并且代码正确设置了字段
以下是调试工具栏中显示的消息
XXXXXX
09:29:40 3. sizeGen=
09:29:40 3. 功能=
09:29:40 2.modelNbr=
09:29:40 1.modelNbr=
09:29:40 输入图像尝试代码
09:29:40 RemanRental>>>在PageLoad之后进入
09:29:40 >>>> sessionScope.rentDisplay 为空
09:29:40 >>>> 页面加载前：sessionScope.rentDisplay 为空
XXXXXX
这里是记录的 sessionScoped 变量：
XXXXXXXX 凯特姆：2362656
口径：25G-FDS-1200
rentDisplay: MultLoadHandDisplay
rentView：多个负载处理程序
XXXXXXXX
【问题讨论】：
-
我认为问题在于您将 onclick 用于仅用于客户端 JS 的服务器端 JS（因此，我相信，除了在浏览器控制台中生成错误之外，代码什么都不做） - 而且您正在使用 norefresh 作为 refreshMode
-
onClick 事件用于服务器端 javascript，是的，我正在使用 norefresh：refreshMode="norefresh"。我在上面添加了 onClick 事件的图像
