Use Java within Javascript -


i have jsp page looks following:

what intent is, current environment via system variable , generate correct url environment.

<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %> <%@ taglib prefix="logic" uri="http://struts.apache.org/tags-logic" %>  <% string sysenv = ""; if(system.getproperty("env.name").equals("test")) {     sysenv = "test"; }  %>  <!doctype html public "-//w3c//dtd xhtml 1.0 strict//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-strict.dtd"><html> <head>     <%@ include file="/includes/common.jsp" %>     <script type="text/javascript" src="<c:out value="${requestscope.scriptslocation}"/>/scripts/general.js"></script>      <c:if test="${requestscope.isfeed == true}">         <jsp:include page="/includes/someinclude.jsp"/>         <script src="http://www.myothersite.com/feed/d/some.js" type="text/javascript"></script>          <script type="text/javascript">         var environ = <%=sysenv%>;          if(environ == 'test'){                 var theurl = 'http://mywebsite.com?isfeed=true&env=test';         } else {         var theurl = 'http://mywebsite.com?isfeed=true';         }         ...      </script>  ...

i think i'm supposed have tags-logic import looping i'm trying achieve in java, not working.

since you're in jsp why not (roughly) this:

<script>   var url = 'http://mywebsite.com?isfeed=true';   if ('<%= system.getproperty("env.name") %>' === 'test') {     url += '&env=test';   }   // etc.

personally i'd move logic out of view , create request-scoped attribute in filter, part of struts 1 request processor, etc. since scriptlets bad. gives opportunity set @ runtime.

in addition, url generation should also moved out of view layer.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
