java - jsp request.getParameter -


edited, still not working exactly, need set page_type on each page of website. page_type needs checked java , code based on page_type. problem is, if else statements not being done correctly. nothing happens because parameter doesn't seem placed. main page page_type being set:

<div id="dyk_area">  <jsp:include page="/imgs/random_dyk.jsp" flush="true">  <jsp:param name="page_type" value="prenataloverviewarea"></jsp:param>  </jsp:include> </div>

where code being checked

<% string pagetype = request.getparameter("page_type")==null?"": request.getparameter("page_type");  string image_name="";        if(pagetype.equals("prenataloverviewarea")){         int random = (int )(math.random() * 10 + 1);         image_name= "/images/did_you_know/dyk_p_" + random + ".png";     }     else if(pagetype.equals("prenatalnorm")){         int random = (int )(math.random() * 25 + 1);         image_name= "/images/did_you_know/dyk_p_" + random + ".png";     }     else if(pagetype.equals("overviewarea")){         int random = (int )(math.random() * 20 + 1);         image_name= "/images/did_you_know/dyk_" + random + ".png";     }     else if(pagetype.equals("overviewnorm")){         int random = (int )(math.random() * 45 + 1);         image_name= "/images/did_you_know/dyk_" + random + ".png";     }  if(!image_name.equals("")){ %>  <img id="dyk_random" src="<%=image_name%>"/>  <%}%>

you using type variable value request parameter in if condition using page_type

include jsp this

<div id="dyk_area">    <jsp:include page="/imgs/random_dyk.jsp" flush="true">      <jsp:param name="page_type" value="prenataloverviewarea" />    </jsp:include> </div>

on included jsp

<%     system.out.println("page type : "+request.getparameter("page_type"));     string page_type = request.getparameter("page_type");     if(page_type.equalsignorecase("prenataloverviewarea")){         int random = (int )(math.random() * 10 + 1);         image_name= "/images/did_you_know/dyk_" + random + ".png";     }      else if(page_type.equalsignorecase("prenatalnorm")){         int random = (int )(math.random() * 25 + 1);         image_name= "/images/did_you_know/dyk_p_" + random + ".png";     } %><img id="dyk_random" src="<%=image_name%>"/>
