Get and set user timezone in cookies with jQuery


  1. Find the user timezone from it’s browser default time and then get the confirmation from the user about it’s timezone.
  2. User should be able to select different time zone
  3. Store the timezone in a cookie
  4. Perform the above procedure only if the user is logged in ( identity)


  • Using jQuery check if user is authenticated ( identity)
  • If authenticated check if the timezone cookie is already set
  • If the cookie is not set yet, get confirmation from user about it’s timezone using bootstrap modal and store it in a cookie


Add a bootstrap modal form to your page with timezone drop-down list:

 <div class='modal fade' id='modalTimeZoneApprove' tabindex='-1' role='dialog' aria-labelledby='myModalLabel'>
 <div class='modal-dialog' role='document'>
 <div class='modal-content'>
 <div class='modal-header'>
 <button type='button' class='close' data-dismiss='modal' aria-label='Close'><span aria-hidden='true'>&times;</span></button>
 <h4 class='modal-title'>Approve Your TimeZone</h4>
 <div class='modal-body'>
 <p>Your default time zone is : <span id="spanTimeZone"></span></p>
 <br />
 <p>You can change your timezone: </p>

the modal will looks like this:

Now add JavaScript/jQuery methods to set the cookies if the users is authenticated (using Identity)

 function getCookie(cname) {
            var name = cname + "=";
            var decodedCookie = decodeURIComponent(document.cookie);
            var ca = decodedCookie.split(';');
            for (var i = 0; i < ca.length; i++) {
                var c = ca[i];
                while (c.charAt(0) == ' ') {
                    c = c.substring(1);
                if (c.indexOf(name) == 0) {
                    return c.substring(name.length, c.length);
            return "";

 function setCookie(cname, cvalue, exdays) {
            var d = new Date();
            d.setTime(d.getTime() + (exdays * 24 * 60 * 60 * 1000));
            var expires = "expires=" + d.toUTCString();
            document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/";

 function checkCookie(cname) {
            var cookieName = getCookie(cname);
            if (cookieName != "") {
                alert("Welcome again " + cookieName);
            else {
                cookieName = "GMT  " + get_time_zone_offset();
                if (cookieName != "" && cookieName != null) {
                    setCookie(cname, cookieName, 365); MediaQueryList

  function get_time_zone_offset() {
            var current_date = new Date();
            return -current_date.getTimezoneOffset() / 60;

 $(document).ready(function () {
            var isAuthenticated = '<%=HttpContext.Current.User.Identity.IsAuthenticated %>';
            if (isAuthenticated=="True") {

                var cookieName = getCookie("AccountTimeZone");
                if (cookieName != "") {
                    //do nothing!
                else {
                    cookieName = "GMT  " + get_time_zone_offset();

                $('#zoneList').on('change', function () {
                    $("#spanTimeZone").text($("#zoneList option:selected").text());

                $("#confirmModalTimeZone").click(function () {
                    var zone = $("#spanTimeZone").text();
                    if (zone != "" && zone != null) {
                        setCookie("AccountTimeZone", zone, 365);

Filtering Dependent Picklist(OptionSet) Javascript for Quick Create Form Microsft Dynamics CRM 2013

Quick create form is a new feature of Microsoft Dynamics CRM , that could be enabled for forms to create a new related record inside the CRM without opening new form and leaving the current form that you are working on. it’s making easy creating records on the fly but make it harder to create java script function on this kind of form.

Quick Create Form purpose is different from main forms and they don’t support all the capabilities of main forms. The following controls cannot be added to quick create forms:


  • Sub-grids
  • Quick View Forms
  • Web resources
  • Notes
  • Bing Maps

Also some other CRM JavaScript controls are not supported in quick create form like Xrm.Page.getControlor Xrm.Page.getAttribute , …

so in order to implement dependent option-set (pick-lists) in quick form we can use JavaScript and JQuery  directly in the form. Although it’s not supported customization, I couldn’t find any supported client side solution for this.

here are the steps for implementing dependent picklist in  create quick form CRM 2013:

Scenario:  I have two option-set issue (new_issue) and issuesubtype(new_issuesubtypewhich the issue sub type should be filtered based on the values in issue option-set. I’m going to filter it based on the appearance of text values from issue to issue sub type. So if issue = electrical the function would find all the issuesubtype  contains electrical string in it.

Use below code on change event of first option-set(issue):

function IssueType_OnChange_Iframe() {

var showOnlyOptionsSimilarToText = function (selectionEl, str) {

// cache the jQuery object of the &lt;select&gt; element
var el = $(selectionEl);
if (!"options")) {
//cache all the options inside the &lt;select&gt; element for easy recover"options", el.find("option").clone());
} debugger;
try {
if (el.length != 0)
var newOptions ="options").filter(function () {
var text = $(this).text();
if (text != null || text != '') {
return text.match(str);
catch (err) {
var error = err.message;

var userInput = $('#new_issue')[0].title;
showOnlyOptionsSimilarToText($("#new_issuesubtype_i"), userInput);

In order for this code to work you should add JQuery to your form.

This code only look at text values selected in first optionset and filter the second one based on that text value.

the second optionset id is new_issuesubtype but  I used the id of the second optionset select tag.(you can get it using IE developer or firebug)
