Question

这是我的data.jsp，当我部署它时，它正常工作但当我试图通过url访问这个jsp时。这些是我添加到这个jsp的jstl ......

<!DOCTYPE html>
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form" %>
<%@ taglib uri="http://www.springframework.org/tags" prefix="spring"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
<html lang="en">

它给了我以下例外。

Unterminated &lt;form:option tag
--------------------------------

<tbody>
     <tr>
         <c:forEach items="${data}" var="data">
           <td class="td-top td-left">
              <form:select class="selectpicker form-control select-di" path="eastOrder" id="east-order" isChanged="false">
                 <form:option value="1" <c:if test="${data.order == '1'}">selected="true"</c:if>>1</form:option>
                 <form:option value="2" <c:if test="${data.order == '2'}">selected="true"</c:if>>2</form:option>
                 <form:option value="3" <c:if test="${data.order == '3'}">selected="true"</c:if>>3</form:option>
                 <form:option value="4" <c:if test="${data.order == '4'}">selected="true"</c:if>>4</form:option>
              </form:select>
           </td>
           <td class="td-top">
               <form:select class="selectpicker form-control select-cl" path="eastCl" id="east-cl" isChanged="false">
                    <form:option value="default"> </form:option>
                    <form:option value="x" <c:if test="${data.cl == 'x'}">selected="true"</c:if>>X</form:option>
                    <form:option value="y" <c:if test="${data.cl == 'y'}">selected="true"</c:if>>Y</form:option>
                    <form:option value="w" <c:if test="${data.cl == 'z'}">selected="true"</c:if>>Z</form:option>
                    <form:option value="z" <c:if test="${data.cl == 'w'}">selected="true"</c:if>>W</form:option>
               </form:select>
           </td>
        </c:forEach>
     </tr>

我该如何解决这个问题。提前谢谢。

Answer 1

您可以使用EL三元运算符${condition?'true statement':'false statement'}代替<c:if>

喜欢 -

<form:select class="selectpicker form-control select-di" path="eastOrder" id="east-order" isChanged="false">
                 <form:option value="1" ${data.order =='1'? 'selected="true"' : '' }>1</form:option>
                 <form:option value="2" ${data.order =='2'? 'selected="true"' : '' }>2</form:option>
                 <form:option value="3" ${data.order =='3'? 'selected="true"' : '' }>3</form:option>
                 <form:option value="4" ${data.order =='4'? 'selected="true"' : '' }>4</form:option>
              </form:select>

Answer 2

我有同样的问题，我通过在标签中使用标签解决，使用下面的代码作为参考：

你必须使用这段代码：

<h3 class="cor"> <?php session_start(); $email = $_SESSION['email']; require_once('conecta.php'); $pasta = "uploads/"; $objDb = new db(); $link = $objDb->conecta_mysql(); $consulta = mysqli_query($link, "SELECT * FROM arquivos WHERE email_vol = '$email'"); while ($resultado = mysqli_fetch_array($consulta)) { $link = $pasta . $resultado["nomearq"]; $descr = $resultado["dataup"]." / " . $resultado["nomearq"]; echo "<a href='$link'>$descr</a><br>"; } ?> </h3>

和

<%@ taglib prefix="c" uri="http://www.springframework.org/tags/form"%>

Answer 3

我遇到了同样的问题，我用：

解决了

selected="${data.order =='1'? 'selected' : '' }"

您可以这样做：

<form:select class="selectpicker form-control select-di" path="eastOrder" id="east-order" isChanged="false">
     <form:option value="1" selected="${data.order =='1'? 'selected' : '' }">1</form:option>
     <form:option value="2" selected="${data.order =='2'? 'selected' : '' }">2</form:option>
     <form:option value="3" selected="${data.order =='3'? 'selected' : '' }">3</form:option>
     <form:option value="4" selected="${data.order =='4'? 'selected' : '' }">4</form:option>
</form:select>

如何在<form：option> </form：option> </c：if>中添加<c：if> jstl
