jspページでSpring <form：input>タグを使用してプレースホルダーHTMLを使用する方法

私はjspページでこのコード行を使用します：

<tr>
 <td> <form:label path="formDescription.daySchedule"> 
 <spring:message code="label.input.daySchedule"/> </form:label>
 </td> 
<td> <form:input path="formDescription.daySchedule" placeholder="<spring:message code="label.input.dayScheduleExample"/>" /> 
</td>  
<td><form:errors path="formDescription.daySchedule"/>
</td> 
</tr>

Html placeholderタグを使用して入力フィールドに例をレンダリングしたいのですが、別の言語でレンダリングしたいという問題があります。しかし、ページをレンダリングしようとするとエラーが発生します。

他のタグ内でタグを使用することはできないと思います。 JSP式言語（EL）で試してください：

<spring:message code="label.input.dayScheduleExample" var="dayScheduleExample"/>

<tr>
 <td> <form:label path="formDescription.daySchedule"> 
 <spring:message code="label.input.daySchedule"/> </form:label>
 </td> 
<td> <form:input path="formDescription.daySchedule" placeholder="${dayScheduleExample}" /> 
</td>  
<td><form:errors path="formDescription.daySchedule"/>
</td> 
</tr>

私のために働く、私は以下のようにjavascript/jqueryで属性プレースホルダーを追加しました：

$("#myID").attr('placeholder', '<spring:message code="myCode"/>');

ここでは、aspマークアップが間違っていると思います。

placeholder="<spring:message code="label.input.dayScheduleExample"/>"

次のように置き換えます。

placeholder='<spring:message code="label.input.dayScheduleExample"/>'

Spring 3以降、フォームタグは動的属性をサポートします。
