如何根据jsp中的条件去除ton子?
原标题:how to disable buttons based on a condition in jsp?

我如何通过检查我的垃圾中的条件来消除一个纽子? 如果情况确实如此,如果听起来不实,那么纽伦就残疾了。 条件是检查变数的价值。 我知道如何用java书写器去除一个 but子,但与jsp中的条件一样,使用script子是我无法看到的。 它是完全可能的?

最佳回答

Try using JSTL Construction as this:

<input type="button" <c:if test="${variable == false}"><c:out value="disabled= disabled "/></c:if>">

Or simply you could do it using el directly like this:

<input type="button" ${ condition ?  disabled="disabled"  :   }/>

例如:

<input type="button" ${ someVariable eq 5  ?  disabled="disabled"  :   }/>

我的做法是这样:

 <c:choose>
    <c:when test="${condition == true}">
      <input type="button" disabled="disabled"/>
    </c:when>
    <c:otherwise>
      <input type="button" />
    </c:otherwise>
 </c:choose>
