Hard problem on forms and JS

Copy linkTweet thisAlerts:
Mar 01.2010

Hey there folks. I have a task regarding forms and JavaScript. I’ve been reading for the past couple of weeks, but didn’t find a popper solution to the task, here it is:

I have a form. Once the user clicks on the first <select> menu, second <select> menu must appear. After the user has clicked on the second <select> menu a final input field must appear. It goes like this:

Choose car type: car1,car2,car3…carN

After the user has chosen car type: engine1,engine2,engine3…engineN

After the user has chosen the engine: the price of the car appears.

After all of the inputs are completed a script takes the data and sends them to a given mail.

I’ve had some success with usableforms(quirksmode), but I don’t know how to “extract” the price, since there are a lot of fields. Any suggestions are welcome.

@FangMar 01.2010 — Sounds like you are using mailto rather than a server-side script where you wouldn't have the problem.

@dig1tyauthorMar 01.2010 — http://treniram.com/ins/jstest.html Here is the test page. It only uses JS for the Usable Forms. I haven't got to the point where I need the data, I don't know how to get the data from the 3rd input field.

// or
document.forms[0].lname.value

Success!
