问题
I'm giving a User object to JSP and want to compare an attribute of the user with a given String. What I'm doing right now is the following:
<input type="radio" name="lang" value="ger" <c:if test="${user.comLanguage.equals("ger")}">checked="yes"</c:if>/>German</br>
But all I get is the following Exception:
org.apache.jasper.JasperException: /WEB-INF/jsp/library/home.jsp (line: 22, column: 95) equal symbol expected
where column 95 is one of the letters of comLanguage.
What's the correct syntax here?
回答1:
Try this :
<c:if test="${user.comLanguage=='ger'}">
Also you can try ternary if:
${user.comLanguage=='ger' ? 'checked' : ''}
