Question

submitting a form without the use of a submit button

Asked by: jameskane

Hi,
I have a drop down box with menu items which are dynamically generated. The user selects an item, clicks the submit button and it all works. HOWEVER, many of my clients have requested that I eliminate the submit button - and have the form submit automatically when the user selects a menu item. Can this be done . I am using coldfusion 7. Many thanks

<select onchange="form.submit()">
<option>youroption1</option>
<option>youroption2</option>
</select>

This will submit the form where the select element is.
As you know you do not want to use submit button. That makes it that you want to use JS to submit the button. If JS is disabled this will not work. Though, your client are requesting it so if they have disabled JS they will have to enabled it. Though usually it is enabled.

Well, if javascript is enabled you can use the above example, but if javascript is disabled you can display a regular form, like this:

<script language="javascript">
<!--
    document.write('<select onchange="form.submit()">');
    document.write('<option>youroption1</option>');
    document.write('<option>youroption2</option>');
    document.write('</select>');
//-->
</script>

<noscript>
<form method="post">
    <select name="selectmenu">
         <option>youroption1</option>
         <option>youroption2</option>
    </select>
    <input type="submit">
</form>
</noscript>


This would display a form without a submit button if javascript is enabled, but if javascript is disabled, it would display a form with a submit button.

Many thanks for the help everyone. I'll go with your solution Pinal - I use a fair amount of javascript on the page in other areas in any case. It works perfectly !

May I suggest
this.form.submit()
to make it work in all browsers?
and I have not tested, but
<noscript>
<input type="submit">
</noscript>

would be simpler than document.write the form

 

by: andw928Posted on 2005-08-30 at 08:28:26ID: 14785701

Well I put it in document.write so that the user without javavscript enabled will not see the first form AND the second form. Therefore, if you have javascript disabled, you see for #2 only, and if you have javascript enabled, you see the first form in the javascript document.write.
