Help, please! :) I need a movable slider.

Question

So, below, with the accidental highlighted area. I want them to be able to move a circle (Well...to be honest it would be considered an image, I suppose.) left or right when my audience is filling out this form. If I can't do it like this, can you think of any other ideas on how they could mark on the document to indicate where they're at on the scale? I appreciate any help! I'm trying to do something a little different than the 1-10 scale. If I don't get any responses, I'll probably just suck it up and do that. 😞

There isn't a slider in set of native PDF form fields, but you can use a script and a button to create the illussion of a slider. This will only work when the PDF is opened in desktop Acrobat Pro or Reader. It won't work on a mobile device or in pretty much every other PDF viewer.

Here's the basic outline of how to do it.

1) Place a fully transparent button over the total area of the slider location.

2) Add a text field for displaying the slider position.

2) Add a script to the Button Down event that starts an interval timer.

3)The interval timer runs a script that captures the mouse position and moves marker with the mouse. The script will need to detect the initial position to ensure the click is actually on the marker and set movement limits. The marker can be either an annotation or another form field.

4) Add script to both the Mouse Up and Mouse Exit events to terminate the timer and set the slider value.
