Question

我想显示所选的dropwdown值，以便管理员可以编辑表单而不必再次选择该值。我尝试了这段代码，但无法正常工作，该值未显示所选的值，它需要管理员再次选择..是否存在任何问题？你们任何人都可以建议一些代码或修理我的代码吗？

    pw.println("<div class=\"form-group\">");
    pw.println("<label class=\"control-label col-lg-2\">Employment Type <span class=\"required\">*</span></label>");
    pw.println("<div class=\"col-lg-10\">");
    pw.println("<select class=\"form-control m-bot15\" name=\"j_empType\" value='"+ j.getJobemptype() +"' required/> \n " +
    "<option value=\"\" selected disabled>Please Select...</option> \n " +
    "<option value=\"Permanent\">Permanent</option> \n " +
    "<option value=\"Contract\">Contract</option> \n " +
    "<option value=\"Temporary\">Temporary</option> \n " +
    "<option value=\"Part Time\">Part Time</option>");
    pw.println("</select>");
    pw.println("</div>");
    pw.println("</div>");

Answer 1

我没有收到您的代码，因为它有点未经格式化且无用。我认为您的意思是：

好，终于明白了哈哈哈

pw.println("<div class=\"form-group\">");
   pw.println("<label class=\"control-label col-lg-2\">Employment Type <span class=\"required\">*</span></label>");
   pw.println("<div class=\"col-lg-10\">");

   if(!"".equalsIgnoreCase(j.getJobemptype()) && j.getJobemptype()!=null){

        if(j.getJobemptype().equalsIgnoreCase("Permanent")){

            pw.println("<select class=\"form-control m-bot15\" name=\"j_empType\" value='"+ j.getJobemptype() +"' required/> \n " +
               "<option value='"+ j.getJobemptype() +"'>"+j.getJobemptype()+"</option>\n " +
               "<option value=\"Contract\">Contract</option> \n " +
               "<option value=\"Temporary\">Temporary</option> \n " +
               "<option value=\"Part Time\">Part Time</option>");
            pw.println("</select>");

        }else if(j.getJobemptype().equalsIgnoreCase("Contract")){

            pw.println("<select class=\"form-control m-bot15\" name=\"j_empType\" value='"+ j.getJobemptype() +"' required/> \n " +

            pw.println("</select>");
        }else if(j.getJobemptype().equalsIgnoreCase("Temporary")){

                            pw.println("</select>");

                            }
                              }else {

                                  "<option value=\"Contract\">Contract</option> \n " +
                                  "<option value=\"Temporary\">Temporary</option> \n " +
                                  "<option value=\"Part Time\">Part Time</option>");
                                pw.println("</select>");
                                  }
