cfslider - not passing value to forms

[KDN0211]

I am missing something?

This form returns only "go" - not the value of slider1. It wioll onhly retunr a value only works if I use format applet.

<cfform method="post" name="form01" >
    <cfslider name="slider1"
    format="HTML"
    vertical="false"
    width="350"
    value="100"
    min="0"
    max="200"
    increment="10"
    tip="true"/>
    <cfinput type="submit" name="go" value="go">
</cfform>

If you have, then there are two of us.

Seems like a bug to me. Couldn't find that one in Adobe Bug database either. Go ahead and post a new one, I say.

You could probably go around this by using Javascript function to change a value of a hidden input field.

Make that three of us (I am running 9.0.1, fully patched).  I've annotated the docs to point out there example doesn't work.  And will vote for a bug if you raise one and post the ref back here.

Thanks for checking it out. Here is the bug report:

*****BUG******
Concise problem statement:
Steps to reproduce bug:
1. Run this code:
<cfform method="post" name="form01" >
    <cfslider name="slider1"
    format="HTML"
    vertical="false"
    width="350"
    value="100"
    min="0"
    max="200"
    increment="10"
    tip="true"/>
    <cfinput type="submit" name="go" value="go">
</cfform>

Results: slider1 returns no value on submit - actually does not exist in the form submit. It only works in applet (which is not practical for our users.)
Expected results: slider1 should be returning the slide value.

See post: http://forums.adobe.com/thread/796754?tstart=0. Two other users get the same results.

What's the direct URL to the bug?  I cannae find it (which makes it hard to vote for 😉

I had to come back at this issue, because I need a slider in one of my forms.

The solution would be using the onchange attribute to call a javascript function which updates a hidden form field.

Cfslider documentation doesn't give any clue about the javascript function properties that will be passed. http://www.raymondcamden.com/index.cfm/2010/3/30/Quick-example--updating-stuff-with-CFSLIDER offers help, luckily.

For example, my cfslider controls the opacity of the page background image.

function updateBackgroundAlpha(ob,value)

{

    document.getElementById('preview_pagebgimage').style.opacity = value/100;

   // insert hidden form field update here

}

And yeah, it's stupid that cfslider only supports integer values. I would have liked to use min = 0, max = 1, increment = 0.1.
