Alter multiple columns in the Database based on selected values- Hibernate - spring

Question

I am displaying the details of a particular table in my JSP page using a for-each loop in the following manner:
<c:forEach items="${List2}" var="alist">
<tr>
<td>
<input type="checkbox" name="check" value="${alist.check}">
</td>
<td>${alist.two}</td>
<td>${alist.three}</td>
<td>${alist.four}</td>
</tr>
</c:forEach>
<input type="radio" id="agree" value="Agree"/>Agree
<input type="radio" id="disagree" value="Disagree"/> Disagree
<input type="submit" value="Submit"/>
Now, there is no column named "check" in my DB. It is a transient field in my POJO. I do have a Agree/Disagree column in my DB. I want to check particular rows, click "Agree" or "Disagree" and on clicking Submit, the Agree/Disagree column for those records should be updated respectively. I'm using Spring MVC with Hibernate. Please tell me if any more info is required from my side.

You can do this with simple jQuery, Set class(say .chkbox here) to all checkboxes. Whenever any change event happened say,
if checked, the value of checkbox added to JS array.
If unchecked, the value will be removed from JS array.
$(document).ready(function() {
var selectedArray = [];
$('.chkbox').change(function() {
if($(this).is(":checked")) {
selectedArray.push($(this).val());
} else {
selectedArray.pop($(this).val());
}
//alert(selectedArray);
$("#textbox1").val(selectedArray);
});
});
Finally I used textbox to hold all the selected checkboxes value. You can make it into a hidden give a name attribute.
<input type="checkbox" class="chkbox" value="101"> This is 101<br />
<input type="checkbox" class="chkbox" value="102"> This is 102<br />
<input type="checkbox" class="chkbox" value="103"> This is 103<br />
<input type="checkbox" class="chkbox" value="110"> This is 110<br />
<input type="checkbox" class="chkbox" value="111"> This is 111<br />
<input type="checkbox" class="chkbox" value="112"> This is 112
<br />
<input type="hidden" id="textbox1" name="selectedArray" />
Sent it to a controller and split the values by comma (,).
Update :
In your code, you can update like this.
<c:forEach items="${List2}" var="alist">
<tr>
<td>
<input type="checkbox" class="chkbox" name="check" value="${alist.check}">
</td>
<td>${alist.two}</td>
<td>${alist.three}</td>
<td>${alist.four}</td>
</tr>
<input type="hidden" id="textbox1" name="selectedArray" />
</c:forEach>
That's all about required.
See the JS Demo how it works. Hope this helps.
