ASP.NET MVC Html Helper Extensions and Rendering Their Required "include"s
- by Jimbo
I have build a custom Html Helper extension as follows:
public static string DatePicker(this HtmlHelper helper, string name, string value)
{
return string.Format(@"<script type='text/javascript'>
$(document).ready(function(){{
$('#{0}').datepicker({{
changeMonth: true,
changeYear:true,
dateFormat: 'd-M-yy',
firstDay: 1, showButtonPanel:
true,
showWeek: true
}});
}});
</script>
<input type='text' name='{0}' id='{0}' value='{1}'>", name, value);
}
The problem is that this now requires the page to "include" the following:
<script src="/Scripts/jquery-1.4.2.min.js" type="text/javascript"></script>
<script src="/Scripts/jquery.ui.datepicker.min.js" type="text/javascript"></script>
And a few other items. The questions are as follows:
Is there a serious processing
overhead if I were to include these
items in EVERY page (like in the
Site.Master for example) thus
negating the need for the HtmlHelper
to organise the "includes" -
considering there would end up being
about 20 includes for all the
different types of jQuery UI widgets
used throughout the site.
If the HtmlHelper sorts out the
"includes", it will add one every
time this DatePicker is used (often
there are two on a page) Does anyone
have a way of determining whether or
not the user has already rendered
the same type of control on the
page, thus not re-including the same
jquery libraries when multiple
instances of the DatePicker (for
example) are used?
