Comment on Tutorial : Click to remove an element from a select html form using javascript By Emiley J.
Hi,

I am new to html, and javascript.

I've built a form, with one field with a click of a character A-Z and/or 0-9 will passit to my field in my form.

I am using a simple javascirpt passit function.

I am also wanting to delete the last character.

But I can not find a simple function that will allow me to delete the last character as I click on a character I would like to click and delete just as easily.

Here is my passit function:

function passit(str)
{document.plate.plateinput.value+=str}

I copied the same function and changed the name and used a minus instead of a plus in front of the equal sign but it didn't work:

function clearit(str)
{document.plate.plateinput.value-=str}

Can you help me here.

I've assigne this " <- " on my form to the javascript "clearit" so every time I click on " <- " I want to delete the last character in my field.

Thank you.

Tom :-)
