Changing form to include a submit button for WCAG

问题

I currently have a form like so:

<form action="#">
    <select {if $isPostRequest}disabled="disabled" {/if}size="1" name="locale" 
onchange="location.href={if $languageToggleNoUser}'{$currentUrl|escape}{if strstr($currentUrl, '?')}&amp;{else}?{/if}setLocale='+this.options[this.selectedIndex].value{else}('{url|escape:"javascript" page="user" op="setLocale" path="NEW_LOCALE" source=$smarty.server.REQUEST_URI}'.replace('NEW_LOCALE', this.options[this.selectedIndex].value)){/if}" class="selectMenu">{html_options options=$languageToggleLocales selected=$currentLocale}</select>
</form>

It currently causes a WCAG 2.0 error, as all forms need a submit button.

I'm wondering how I could change this code to include a submit button. The code for the onchange option is quite convoluted, and I don't understand it.

Thanks.

回答1:

WCAG 2.0 does not require to have a submit button. What you link to is a technique, which is informative (not normative), and it’s only one of possibly many ways to achieve the guideline 3.2.2.

So it can be conforming to have no submit button, for example when

the user has been advised of the behavior before using the component
