Knockout Support in JQuery CurrencyTextBox widget

10 Aug 20174 minutes to read

Knockout support allows you to bind the HTML elements against any of the available data models. It is of two types.

  • One-way binding
  • Two-way binding

One-way binding refers to the process of applying observable values to all the available properties of the CurrencyTextBox widget, but the changes made in CurrencyTextBox widget are not reflected and triggered in turn to the observable collection. This kind of binding applies to all the properties of the CurrencyTextBox widget.

Two-way binding supports both the processes; it applies the observable values to the CurrencyTextBox widget properties as well as the changes made in the CurrencyTextBox widget are also reflected back and triggered within the observable collections.

For more information about the knockout binding, refer the following online documentation in the given link location,

The following example depicts the way to bind data to the CurrencyTextBox widgets through knockout support that enables and populates data to the CurrencyTextBox widget based on the value set to the other CurrencyTextBox widget.

  • HTML
  • <!DOCTYPE html>
    <html xmlns="">
        <link href="" rel="stylesheet" />
        <script src=""></script>
        <script src=""></script>
        <script src=""> </script>
        <script src=""></script>
        <div id="center">
            <table cellpadding="10">
                            <label for="currency">Currency</label>
                            <input id="currency" type="text" data-bind="ejCurrencyTextbox: { value: currencyValue }" />
                            <input type="text" class="input ejinputtext" data-bind="value: currencyValue" />
         <script type="text/javascript">  
            window.viewModel = {
                currencyValue: ko.observable(80),
            jQuery(function ($) {
            .input {
                height: 27px;
                text-indent: 10px;
                width: 81%;
