嗨,我在 JSP 中有一个自定义标签
<dc:drawMultiSelect
availableLabel='<%=request.getAttribute("availableCoreColumn").toString()%>'
selectedLabel='<%=request.getAttribute("selectedCoreColumns").toString()%>'
availableCName="selectCol"
selectedCName="selectedCol"
availableCId="select1"
selectedCId="select2"
sort="off"
columnHelp="on"
helpURL='<%=((Map)request.getAttribute("constants")).get("WEB_CONTEXT").toString()%>/web/ABCGlossary.jsp'
selectSize="8"
selectWidth="250px"
selectMultiple="true"
availableMap='<%=((HashMap) request.getAttribute("availableColMap"))%>'
selectedMap='<%=((HashMap) request.getAttribute("selectedColMap"))%>'>
它工作正常,除了 helpURL='<%=((Map)request.getAttribute("constants")).get("WEB_CONTEXT").toString()%>/web/ABCGlossary.jsp'
它没有在 jsp 中翻译它给出的输出类似于 %=((Map)request.getAttribute("constants")).get("WEB_CONTEXT").toString()%>/web/ABCGlossary.jsp
你能帮我启用 rtexprvalue 有什么问题吗
