<BODY>
<H2>JavaScript Date Picker Test</H2>This is a demonstration of some basic
JavaScript DHTML datepicker functionality, allowing you to present a drop-down
calendar to your users at the click of a button so they can easily choose a date
that will be inserted into a text field.
<P>There are many other datepickers available on the Internet...this happens to
be the one that I wrote. You are free to use it in any way you'd like in your
own applications. If you're feeling nice, you could even include my name with
the code.
<P>Please see the JavaScript code on the page source itself for additional
information.
<P>
<HR>

<P>
<FORM>Here's an example of displaying the datepicker below a text field:
<BR><B>A Date:</B> <INPUT name=ADate> <INPUT onclick="displayDatePicker('ADate');" type=button value=select> </FORM>
<P>
<FORM>And here's an example of displaying it below the button that was clicked:
<BR><B>Another Date:</B> <INPUT name=AnotherDate> <INPUT onclick="displayDatePicker('AnotherDate', this);" type=button value=select>
</FORM>
<P>
<FORM>And here's an example of displaying the resulting value with a date format
of dd.mm.yyyy: <BR><B>Yet Another Date:</B> <INPUT name=YetAnotherDate> <INPUT onclick="displayDatePicker('YetAnotherDate', false, 'dmy', '.');" type=button value=select>
</FORM>
<P>The format of the datepicker (color, fonts, etc.) is easily customized using
CSS. The date format can be customized using either global variables or each
time you call the function that displays the date picker (see the code for more
information). Enjoy.
<P>

<BODY>
<H2>JavaScript Date Picker Test</H2>This is a demonstration of some basic
JavaScript DHTML datepicker functionality, allowing you to present a drop-down
calendar to your users at the click of a button so they can easily choose a date
that will be inserted into a text field.
<P>There are many other datepickers available on the Internet...this happens to
be the one that I wrote. You are free to use it in any way you'd like in your
own applications. If you're feeling nice, you could even include my name with
the code.
<P>Please see the JavaScript code on the page source itself for additional
information.
<P>
<HR>

<P>
<FORM>Here's an example of displaying the datepicker below a text field:
<BR><B>A Date:</B> <INPUT name=ADate> <INPUT onclick="displayDatePicker('ADate');" type=button value=select> </FORM>
<P>
<FORM>And here's an example of displaying it below the button that was clicked:
<BR><B>Another Date:</B> <INPUT name=AnotherDate> <INPUT onclick="displayDatePicker('AnotherDate', this);" type=button value=select>
</FORM>
<P>
<FORM>And here's an example of displaying the resulting value with a date format
of dd.mm.yyyy: <BR><B>Yet Another Date:</B> <INPUT name=YetAnotherDate> <INPUT onclick="displayDatePicker('YetAnotherDate', false, 'dmy', '.');" type=button value=select>
</FORM>
<P>The format of the datepicker (color, fonts, etc.) is easily customized using
CSS. The date format can be customized using either global variables or each
time you call the function that displays the date picker (see the code for more
information). Enjoy.
<P>
