I'm using Struts 2 in my form, and I've marked the line where I'm calling my custom tag. <s:iterator value="bulletins"> <s:if test="approved == false"> <s:form action="ApproveBulletin" method="post"> <table border="2"

How to add custom HTML Tags to Visual Studio and Avoid Squiggly Lines

阅读更多关于 How to add custom HTML Tags to Visual Studio and Avoid Squiggly Lines

问题 I'm using Visual Studio 2013 to create raw HTML pages (i.e. index.html). In my HTML I am implementing custom HTML tags. As such, Visual Studio underlines my custom tags with squiggly lines (due to the warning of "Unknown element ..."). In hopes to get rid of the squigglies, I added my custom tags to the list of "Tag Specific Options" via Tools > Options > Text Editor > HTML (Web Forms) > Formatting > Tag Specific Options . However, the squiggly lines persist. Is there a way to inform VS2013

阅读更多关于 Why won't my Facelets loop variable go out of scope?

问题 I know this looks like a lot of text, but I think it's a pretty simple concept I'm missing. I'm writing a web application with Facelets. I've got a custom tag rq:request-list that takes a list of requests as a parameter and outputs a lovely table to display them. So far, so good. rq:request-list starts out like you'd expect:  <ice:dataTable value="#{list}" var="req"> <ice:column> <f:facet name="header">Date last edited</f:facet> <ice:outputText value="#{req.dateModified}" /> </ice

问题 Every example i can find has the tag handler java class generating html and spewing it out with out.print(someHTML); Is there a way to include a jsp and add attributes to the request instead? 回答1: I haven't tried this but it should be possible by obtaining a RequestDispatcher from the Request object: public int doStartTag() throws JspException { try { pageContext.setAttribute("title", "My Title"); pageContext.getRequest().getRequestDispatcher("/WEB-INF/includes/header.jspf").include
