Replace dashes with other text

I’m trying to replace a dashed line with an answer after a “click here” prompt. Here’s an example:

1) Find the principal parts of the verb “drive” by filling in the blanks below. Click here to check your answer.

I _____ now. (Present tense)
I _____ in the past ( past tense)
I have ______ every day. (Past participle)

After “Click here” is clicked, the above will be changed to:

I drive now. (Present tense)
I drove in the past ( past tense)
I have driven every day. (Past participle)

Is there a way to do this with javascript/scriptaculous? I’m building an instuctional site on English grammar. I’d appreciate some help.

Thanks,
Mike

 

Hi,
If you give your input elements id values, you can then use document.getElementById('idvalue').value = 'newvalue'; from an onClick function attached to your button.
Hope this helps
