At present, the core (:input:) markups do not allow javascript
from the markup.

However, a site administrator or recipe can of course provide
custom (:input:) markups that perform javascript validation.
For example, I might implement the "jsgoto" feature entirely
differently, by defining a new control type:

    (:input jumpbox {Page1$PageUrl}:)
    (:input jumpbox {Page2$PageUrl}:)
    (:input jumpbox {Page3$PageUrl}:)

to be generated from a pagelist by using:

    [[#jumpbox]]
    (:if equal {<$FullName}:)(:input form {$ScriptUrl}:)(:if:)
    (:input jumpbox value={=$PageUrl} label="{=$Title}":)
    (:if equal {>$FullName}:)
    (:input submit post "Go to Page":)
    (:input end:)
    [[#jumpboxend]]

The local customization needed over-and-above the core forms
markup to make (:input jumpbox:) work will likely be something 
as short as:

    $InputTags['jumpbox'][':html'] =
      "<select \$InputFormArgs 
         onchange='window.location.href=this.options[this.selectedIndex].value'
       >\$InputSelectOptions</select>";

    Markup('input-jumpbox', 'input-select',
      '/\\(:input\\s+jumpbox\\s.*?:\\)/e',
      "InputSelect(\$pagename, 'jumpbox', PSS('$0'))");

Once I get the forms.php update in place I'll write up a demonstration
page and/or recipe.
