Jquery ajax call manipulating DHTML

Code snippet to change Check-box state based on Server side call upon dropdown selection change

HTML

<select name=”dropDown” id=”dropDownId”>
<option>Value1</option>
<option>Value2</option>
<option>Value3</option>
<select>  <!– Intentional typo to preserve HTML code –>

<span id=”changingCheckboxes”>
<label for=”group1″>One</label>
<input type=”radio” name=”group1″ id=”1″ value=”option1″/>
<label for=”group1″>Two</label>
<input type=”radio” name=”group1″ id=”2″ value=”option2″/>
<label for=”group1″>Three</label>
<input type=”radio” name=”group1″ id=”3″ value=”option3″/>
<label for=”group1″>Four</label>
<input type=”radio” name=”group1″ id=”4″ value=”option4″/>
</span>

Jquery

function UpdateCheckBoxStatus () {
var CurrentChoice = $(“#dropDownId”).val();
$.ajax({
url: “/serverSideUrl”,
data: { “selectedDropDownId”: CurrentChoice },
type: “post”,
dataType: “json”,
success: function (data) {
SetCheckbox($(“#changingCheckboxes”).children(“input:[type='radio']“), true);
$.each(data.disabled, function () {
SetCheckbox($(“#changingCheckboxes #” + this), false); });
}
});
}

function SetCheckbox (th, state) {
if (state) th.removeAttr(“disabled”);
else if (!state) th.attr(“disabled”, true);
}

$(‘#dropDownId’).change(UpdateCheckBoxStatus);

Java 

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException,
IOException {
String selectedValue = request.getParameter(“dropDownId”);
YourDao yourDao = new YourDao();
Map<String, List<String>> disabledOptions = cycleDao.determineStateDropDown(selectedTool);
String json = new Gson().toJson(disabledOptions);
response.setContentType(“application/json”);
response.setCharacterEncoding(“UTF-8″);
response.getWriter().write(json);
}

Factorial without recursion Java

Here is the non-recursive way of calculating Factorial in Java:

public class FactorialUtility
{
public static BigInteger factorial(int n)
{
BigInteger ret = BigInteger.ONE;
for (int i = 1; i <= n; ++i) ret = ret.multiply(BigInteger.valueOf(i));
return ret;
}
}
