Question

我想从我从Controller传递给JSP的数据中显示一个图像文件。

例如，当您从JSP发送以下值时，

{selectDoctor=[{d_name=MyName, d_imageServerPath=/boardFile/014e40e0ea.PNG, d_imagePath=C:/rachel/014e40e0ea.PNG, di_idx=2, d_imageOriginalName=testImage.PNG, d_idx=2, d_medicalInformation=valuevalue}]}

我已经能够通过语句在标签外显示值。

<c:forEach items="${selectDoctor}" var="sD">
    <select>
        <option value="">Choice Doctor</option>
        <option value="${sD.d_idx}"><img src="${sD.di_imageServerPath}></img>${sD.d_name}</option>
    </select>
</c:forEach>

但与我的期望不同，img标签不起作用。

如何在标签内插入标签？

Answer 1

您无法在tag中插入<option>。Options标记不能包含任何其他标记。尝试使用dropdown <dd> <dl>建立自己的tags。
