Getting kendoDateTimePicker is not a Function in Console when rendering during $(document).ready()

[Matt]

When the following code is run, I get an error in the console indicating that .kendoDateTimePicker is not a function, but the controls render when the convertNewPickerControl() method is called outside the $(document).ready() function.

I also get the same error when I try to convert cloned inputs dynamically (e.g., when a user presses the "Add" button.

The following is the code for the entire page (I'm getting the same issue in our product using similar code).

 

 

<script src="~/Scripts/jquery-3.4.1.min.js"></script>
<script src="~/Scripts/kendo/2022.3.1109/kendo.all.min.js"></script>

@Styles.Render("~/Content/css")
@Styles.Render("~/Content/kendo/styles")
@Styles.Render("~/Content/kendo/css")

<style>
    .row {
        padding-top: 12px;
        padding-bottom: 12px;
    }
</style>

<main>

    <div id="cloneDiv" style="display:none;">
        <div id="row0" class="row">
            <div class="col-md-1 form-label">Date/Time:</div>
            <div class="col-md-5">
                <input id="dateTimePickerFrom_row0" />
            </div>
            <div class="col-md-5">
                <input id="dateTimePickerTo_row0" />
            </div>
            <btn id="button_row0" class="col-md-1 btn btn-outline-info" onclick="addNewRow(this);">Add</btn>
        </div>
    </div>

    <div id="parentDiv">
        <div id="row1" class="row">
            <div class="col-md-3">
                <input id="dateTimePickerBase_row1" class="date-time-picker" />
            </div>
            <div class="col-md-3">
                <input id="dateTimePickerFrom_row1" class="date-time-picker" />
            </div>
            <div class="col-md-3">
                <input id="dateTimePickerTo_row1" class="date-time-picker" />
            </div>
            <btn id="button_row1" class="col-md-1 btn btn-outline-info" onclick="addNewRow(this);">Add</btn>
        </div>
    </div>
</main>

<script>

    var row = parseInt(1);

    console.log('converting before document ready...');
    convertNewPickerControl("dateTimePickerBase_row1")

    $(document).ready(function () {
        console.log('converting within document ready...');
        convertNewPickerControl("dateTimePickerFrom_row1");
    });

    console.log('converting after document ready...');
    convertNewPickerControl("dateTimePickerTo_row1");

    function convertNewPickerControl(sender) {

        var savedStartDate = new Date();

        $("#" + sender).kendoDateTimePicker({
            format: "MM/dd/yyyy hh:mm:ss tt",
            value: savedStartDate,
            min: savedStartDate
        });
        console.log('...successfully converted.');
    }

    function addNewRow(sender) {

        var sourceRow = $('#row0');
        var newRow = $('#row' + row);
        var currentRowNumber = 'row' + row;
        var regex = new RegExp(currentRowNumber, "g");
        var proxyListRegex = new RegExp(/\.ProxyList\[\d+\]/g);
        var _rowRegex = new RegExp(/\_row\d+/g);

        var clonedRow = $('<div>').append(sourceRow.clone()).html().replace(regex, 'row' + (parseInt(row) + 1)).replace(proxyListRegex, '.ProxyList[' + row + ']').replace(_rowRegex, '_row' + (parseInt(row) + 1));

        clonedRow = clonedRow.replace("row0", "row" + (parseInt(row) + 1));
        newRow.after(clonedRow);

        /* convert new inputs to datetimepickers */
        var newFromControl = "dateTimePickerFrom_row" + row;
        var newToControl = "dateTimePickerTo_row" + row;

        convertNewPickerControl(newFromControl);
        convertNewPickerControl(newToControl);

        row = (parseInt(row) + 1);

    }
</script>

As can be seen in the console, the first and last calls to convertNewPickerControl() work, but the call within $(document).ready() does not (and neither do the calls made to convertNewPicker() in addNewRow() -- not shown below):

 

So...I know $(document).ready is executing as the console.log entry is noted.  Why would it be working outside $(document).ready() but not within it (or via the call when adding a new row)?

Hello, Matt,

Thank you for the provided code snippet.

I tested it in this Dojo example and you can see that when the function is called from the document.ready function, the DateTimePicker is initialized as expected.

Could you please provide a runnable example where I can observe the error, or modify the provided Dojo example? I will then be able to investigate and provide further details on the matter.

Thank you in advance for the cooperation. Looking forward to your reply.

Regards,
Martin
