get id of selected rows

[bubu lina]

hello
i have this html table that i populate with jstl .
in a hidden field i place the id :

  <input type="hidden" name="id" id="id" value="${myobj.id}" />  

on submit i call a javascript function:

 <input  type="submit" name="Row" id="Row"
			value="save" onclick="save(this); return true;" />   
<input type="hidden" id="saveRowId" name="saveRowId" />	

the js script is:

  function save(ctrl) {

		
  	if (typeof(ctrl) != 'undefined' && ctrl != null){
        var id = document.getElementById("id").value;
        alert("id: "+id);
        
	
        document.getElementById('saveRowId').value = id; 
 	}  

i need to get the IDS from the table of the selected rows. just getting the first id in the list.no matter what i choose. any ideas of where about i am doing wrong here?
thank you

I do not understand how selected rows pay into this.

element ids are singular so if you have multiple hidden elements, they need to have unique ids. You can reference them with their names.

even if i delete the second hidden field..(saveRowId) i still cannot get the right rows

How is the code supposed to know what the selected rows are?

If you need to read the value of multiple fields, than you need to have a loop or multiple statements.

this is from my page. i have a for each, of course:

  

<c:forEach items="${objects.obj}" var="obj">
				<input type="hidden" name="objId" id="objId" value="${obj.id}" />
				
				<tr>
					<td >${obj.id}</td>
					<td >${obj.name}</td>
					
				</tr>
			</c:forEach>

And as I stated before ids are SINGULAR. You can not have multiple elements with the same id.

ALSO

Your HTML markup is invalid. Your hidden element NEEDS to be in one of the cells.
