Comment utiliser un espace réservé HTML avec la balise Spring <form: input> sur une page jsp

J'utilise cette ligne de code sur la page jsp:

<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>

Je veux utiliser la balise html placeholder pour rendre l'exemple dans le champ de saisie, mais le problème que je souhaite pour le rendre sur différentes langues. Mais cela me donne une erreur lorsque j'essaie de rendre une page:

Je pense que vous ne pouvez pas utiliser une balise à l'intérieur d'une autre balise. Essayez avec le langage d’expression JSP (EL):

<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>

Cela fonctionne pour moi, j'ai ajouté l'espace réservé d'attribut avec javascript/jquery comme ci-dessous:

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

Je pense que votre balisage asp est faux ici:

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

Remplacez-le par:

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

À partir du printemps 3, les balises de formulaire prennent en charge les attributs dynamiques.
