I’m new to progressively enhancing HTML5 forms, and I’m currently trying jQuery UI and HTML5’s new input types to create cross-browser forms. I’m using Modernizr and Yepnope for conditional loading of scripts and following tutorial given at CSS-tricks.com. But I’m getting Object [object Object] has no method 'datepicker' error.

I found that there’s Modernizr.load() which can be used in place of yepnope(), but that didn’t worked and ended up with Object #<Object> has no method 'load' error so I went back to yepnope(). Below is by <Head> section of the webpage.

<Head>
    <title>HTML5 Web Form</title>
    <script type="text/javascript" src="js/jquery-1.7.1.min.js"></script>
    <script type="text/javascript" src="js/modernizr-2.5.2.js"></script>
    <script type="text/javascript" src="js/yepnope.1.5.2-min.js"></script>
    <script type="text/javascript" src="js/custom.js"></script>
    <script type="text/javascript">
    yepnope({
            test: Modernizr.inputtypes.date,
            nope: [
                    "./js/jquery-ui-1.8.17.custom.min.js",
                    "./css/jquery-ui-1.8.17.css"
            ]
    });

    $(function(){
        $("input[type='date']").datepicker(); //this is giving error
    });
    </script>
</Head>

And the <body> has a form with <input type='date' name='dtTest'/>

After a bit Googling, I found that cause for the error is loading of jQuery Core twice, I also followed this, but can’t fix the issue.

Thanks.

Note: I’m testing the page in Chrome 17 and Opera 11.61.

    Here’s what your HTML page should look like:

    <!DOCTYPE html>
<Html>
    <meta charset="utf-8">
    <head>
        <title>HTML5 Web Form</title>
        <script type="text/javascript" src="js/modernizr-2.5.2.js"></script>
        <script type="text/javascript" src="js/jquery-1.7.1.min.js"></script>
        <script type="text/javascript" src="js/yepnope.1.5.2-min.js"></script>
        <script type="text/javascript">

            yepnope({
                test : Modernizr.inputtypes && Modernizr.inputtypes.date,
                nope : [
                    'js/jquery-ui-1.8.17.min.js',
                    'css/jquery-ui-1.8.17.css',
                    'js/datepicker.js'
                ],
                callback : {
                    'jquery-ui-1.8.17.min.js' : function() {
                         $("input[type='date']").datepicker();
                    }
                }
            });
        </script>
    </head>
    <body>
        <div id="lblTest">Hello World</div><br/>
        <form name="frmMain" action="#">
            Date : <input type='date' name='dtTest'/>
        </form>
    </body>
</Html>

    And the content of datepicker.js should be:

    $(function() {
    $("input[type='date']").datepicker();
});

    This works fine on my copy of Chrome, though I’ve not had the chance to check it in other browsers.

    Update: We can avoid using separate datepicker.js by making use of callback block of yepnope more efficiently and binding datepicker() there itself.
