Is it true that the Spring MVC <input:form> does not support the use of the name attribute? This limitation could potentially pose challenges when utilizing javascript document.getElementsByName

Check out my Spring MVC JSP snippet below:

<c:forEach var="trackRecord"  varStatus = "number" items="${contractDetails.trackRecordEntries}" >
  <tr class="tafont">
      <td class="varcar"><form:input readonly = "true" name = "installmentNo" id = "installmentNo" path="trackRecordEntries[${number.index}].installmentNo"/></td>
      <td class="varcar"><form:input readonly = "true" name  = "installmentAmount" id = "installmentAmount" path = "trackRecordEntries[${number.index}].installmentAmount"/></td>   
      <td class="varcar"><form:input readonly = "true" name = "dueDate" id = "dueDate" path="trackRecordEntries[${number.index}].dueDate"/></td>
      <td class="varcar"><form:input cssClass="recievedDate" name = "recievedDate" id = "recievedDate" path="trackRecordEntries[${number.index}].recievedDate"/></td>
      <td class="varcar"><form:input id = "recieptAmount" name = "recieptAmount" path="trackRecordEntries[${number.index}].recieptAmount"/></td>
      <td class="varcar"><form:input id = "delayDays" name = "delayDays" path="trackRecordEntries[${number.index}].delayDays"/></td>     
 </tr>
 </c:forEach>

This code connects an ArrayList of beans to the JSP page, but there is a challenge with using the 'name' attribute in the <form:input> tag. The 'name' attribute is essential for JavaScript validation with 

document.getElementsByName("name");

Looking for any solutions or workarounds?

Answer №1

When utilizing Spring tags such as <form:input>, it's important to note that the name attribute cannot be used in Spring tags. Instead, you must utilize the path attribute of the tag, which will internally convert its value to the name attribute of an HTML tag like so:

<c:forEach var="trackRecord"  varStatus = "number" items="${contractDetails.trackRecordEntries}" >
  <tr class="tafont">
      <td class="varcar"><form:input readonly = "true" path = "installmentNo" id = "installmentNo" /></td>
      <td class="varcar"><form:input readonly = "true" path  = "installmentAmount" id = "installmentAmount" /></td>   
      <td class="varcar"><form:input readonly = "true" path = "dueDate" id = "dueDate" /></td>
      <td class="varcar"><form:input cssClass="recievedDate" path = "recievedDate" id = "recievedDate" /></td>
      <td class="varcar"><form:input id = "recieptAmount" path = "recieptAmount" /></td>
      <td class="varcar"><form:input id = "delayDays" path = "delayDays" /></td>     
 </tr>
 </c:forEach>

In addition, all path variables must be defined in your form as shown below:

public class UoyrForm {

    private String[] installmentNo;
    private String[] installmentAmount;
    private String[] dueDate;
    private String[] recievedDate;
    private String[] recieptAmount;
    private String[] delayDays;
}

Alternatively, you can opt to use simple HTML tags instead.

Answer №2

Have you considered utilizing document.getElementById("specific id value") instead? It seems more efficient given that unique id values are already specified, making the name attribute unnecessary in this context.
