我是 Spring MVC 的初学者，我犯了一些错误......所以我想伪造一个带有按钮和 Thymeleaf 的动态 URL，但它不起作用.我想转义引号或类似的， ${key} 在评估中不正确?

i'm a starter in Spring MVC and i make somes mistakes ... so i want to forge a dynamic URL with a button and Thymeleaf, but it doesn't works. I think about escape quote or similar, the ${key} is not correct in the evaluation ?

<tr th:each="key: ${serverBean.getServerB().keySet()}">
    <td>
        <span th:text="${serverBean.getServerB().get(key)}" />
    </td>
    <td align="center">
        <span th:text="${key}" />
    </td>
    <td th:if="${protoStatusBean.getStatus(key)}" bgcolor="lime" />
    <td th:unless="${protoStatusBean.getStatus(key)}" bgcolor="red"/>
    <td>
        <button th:onclick="window.location.href='/update?server=${key}'">
            <img src="./images/wrench.png" height="15" width="15">
        </button>
    </td>
</tr>

推荐答案

通常，您必须用单引号将文本文字括起来.为了让您的示例正常工作，它应该如下所示:

In general, you have to surround text literals with single quotes. For your example to work, it should look like this:

th:onclick="'window.location.href=\'/update?server=' + ${key} + '\''"

话虽如此，根据您认为最好的方式，还有多种其他方法可以使字符串连接工作.

That being said, there are various other ways to get the string concatenation to work, depending on what you think looks best.

th:onclick="|window.location.href='/update?server=${key}'|"
th:onclick="${'window.location.href=''/update?server=' + key + ''''}"
th:onclick="|window.location.href='@{/update(server=${key})}'|"
