The following guidelines shows how to use the RadioButton to select the answers in an application and to get the selected items. The following screenshot displays a sample Quiz application.

Create the necessary Layout

Create an HTML file and paste the following template to the HTML file for the RadioButton creation.

  • html
  • <!DOCTYPE html>
    <html>
    <head>
        <meta name="viewport" content="width=device-width, initial-scale=1.0,maximum-scale=1.0, user-scalable=no" />
        <title>RadioButton</title>
        <link href="[http://cdn.syncfusion.com/17.2.0.28/js/mobile/ej.mobile.all.min.css](http://cdn.syncfusion.com/17.2.0.28/js/mobile/ej.mobile.all.min.css)" rel="stylesheet" />
        <script src="[http://cdn.syncfusion.com/js/assets/external/jquery-1.10.2.min.js](http://cdn.syncfusion.com/js/assets/external/jquery-1.10.2.min.js)"></script>
        <script src="[http://cdn.syncfusion.com/js/assets/external/jsrender.min.js](http://cdn.syncfusion.com/js/assets/external/jsrender.min.js)"></script>
        <script src="[http://cdn.syncfusion.com/17.2.0.28/js/mobile/ej.mobile.all.min.js](http://cdn.syncfusion.com/17.2.0.28/js/mobile/ej.mobile.all.min.js)"></script>
    </head>
    <body>
        <div align="center">
            <!-- Header control here-->
            <div id="Div1" data-role="ejmnavigationbar" data-ej-title="Quiz Application" data-ej-isrelative="true" data-ej-titlealignment="center"></div>
            <div id="Div2">
                <div>
                    <!--RadioButton content here-->
                </div>
            </div>
            <!-- ScrollPanel control here-->
            <div id="Div3" data-role="ejmscrollpanel" data-ej-target="scroller"></div>
        </div>
    </body>
    </html>

    Create a RadioButton

    To render the RadioButton control, set the data-role attribute to ejmradiobutton for an input element and type attribute as radio.

    Add the following code example to render the radio buttons in the quiz application.

  • html
  • <!--RadioButton content-->
       <table border="0" cellpadding="5">
            <tr>
                <td>
                    1. What is the Expansion for MVC?
                </td>
            </tr>
            <tr>
                <td class="align">
                    <input id="Radio1" name="radbtn" type="radio" data-role="ejmradiobutton" />
                    <label for="Radio1" class="e-m-input-label">Model View Controller</label>
                </td>
            </tr>
            <tr>
                <td class="align">
                    <input id="Radio2" name="radbtn" type="radio" data-role="ejmradiobutton" />
                    <label for="Radio2" class="e-m-input-label">Model Virtual Container</label>
                </td>
            </tr>
            <tr>
                <td class="align">
                    <input id="Radio3" name="radbtn" type="radio" data-role="ejmradiobutton" data-ej-text="Model Visual Controller" />
                    <label for="Radio3" class="e-m-input-label">Model Visual Controller</label>
                </td>
            </tr>
            <tr>
                <td>
                    2. What is the Expansion for USB?
                </td>
            </tr>
            <tr>
                <td class="align">
                    <input id="Radio4" name="USB" type="radio" data-role="ejmradiobutton" />
                    <label for="Radio4" class="e-m-input-label">Universal serialized Buffer</label>
                </td>
            </tr>
            <tr>
                <td class="align">
                    <input id="Radio5" name="USB" type="radio" data-role="ejmradiobutton" />
                    <label for="Radio5" class="e-m-input-label">Universal Serial Buffer</label>
                </td>
            </tr>
            <tr>
                <td class="align">
                    <input id="Radio6" name="USB" type="radio" data-role="ejmradiobutton" />
                    <label for="Radio6" class="e-m-input-label">Universal Serial Bus</label>
                </td>
            </tr>
        </table>

    Now, add the following styles to align the RadioButton and the other contents properly in the quiz application.

  • css
  • <style type="text/css">
    
    td {
    	padding: 5px;
    }
    td.align {
    	padding-left: 20px;
    }
    
    </style>

    The following screenshot is the final output for the above code example.
