Question

Sorry but im an absolute noob with javascript.

Ive made a form for a simple quiz but cant figure out how to make radio’s only click once.

I can select two or three buttons as my answer. i want to change this.

<form name = "Beginners Quiz">

<p>Film speed refers to:</p>
<p><input type="radio" name="Answer 1" id="Answer1" value = "a" onclick =  "recordAnswer(1,this.value"/>How long it takes to develop film. <br/>
<p><input type="radio" name="Answer 2" id="Answer2" value = "b" onclick = "recordAnswer(1,this.value"/>How fast film moves through film-transport system.  <br/>
<p><input type="radio" name="Answer 3" id="Answer3" value = "c" onclick = "recordAnswer(1,this.value"/> How sensitive the film is to light.  <br/>
<p><input type="radio" name="Answer 4" id="Answer4" value = "d" onclick = "recordAnswer(1,this.value"/> None of these makes sense. <br/>

ive been rooting around w3shcools tutorials to no avail. can someone shed some light?

Answer 1

Here’s an approach…
EDIT No Javascript needed, been awhile since I worked with radios.

In the body, you have this:

<form name="beginners_quiz">
<fieldset id="radios"><legend id="quiz">Film speed refers to:</legend>
<input type="radio" name="answer" id="Answer1" value="a" onclick="recordAnswer(1,this.value);" />How long it takes to develop film.<br/>
<input type="radio" name="answer" id="Answer2" value="b" onclick="recordAnswer(1,this.value);" />How fast film moves through film-transport system.<br/>
<input type="radio" name="answer" id="Answer3" value="c" onclick="recordAnswer(1,this.value);" />How sensitive the film is to light.<br/>
<input type="radio" name="answer" id="Answer4" value="d" onclick="recordAnswer(1,this.value);" />None of these makes sense.<br/>
</fieldset>
</form>

This should do it.
