I am trying to change the value of a textbox based on the selection a group of 4 radio buttons. This is not the actual html code, but a simplified version:
<input type="radio" name="radiogroup" id="radiogroup" value="5" />
<input type="radio" name="radiogroup" id="radiogroup" value="10" />
<input type="radio" name="radiogroup" id="radiogroup" value="15" />
<input type="radio" name="radiogroup" id="radiogroup" value="20" />
<input type="text" name="amount" id="amount" />
So what I am trying to do is fill the textbox named "amount" with either 5, 10, 15 or 20 based on which radio button is selected.
I am new to jquery and everything I tried did not work.
Thank you in advance for any help.

Reset to default 6You can easily do this by adding class.
Working Fiddle
HTML:
<input type="radio" name="radiogroup" id="radiogroup" class="radiogroup" value="5" />
<input type="radio" name="radiogroup" id="radiogroup" class="radiogroup" value="10" />
<input type="radio" name="radiogroup" id="radiogroup" class="radiogroup" value="15" />
<input type="radio" name="radiogroup" id="radiogroup" class="radiogroup" value="20" />
<input type="text" name="amount" id="amount" />
JS:
$('.radiogroup').change(function(e){
var selectedValue = $(this).val();
$('#amount').val(selectedValue)
});
ID's are unique, and an ID can only be used on one element in the current document, so change it to classes.
Then attach a change
event handler to the radios, get the checked one, and set the value of the text input to the checked radios value
$('.radiogroup').on('change', function() {
$('#amount').val( this.value );
});
<script src="https://ajax.googleapis./ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="radio" name="radiogroup" class="radiogroup" value="5" />
<input type="radio" name="radiogroup" class="radiogroup" value="10" />
<input type="radio" name="radiogroup" class="radiogroup" value="15" />
<input type="radio" name="radiogroup" class="radiogroup" value="20" />
<br /><br />
<input type="text" name="amount" id="amount" />
Something like:
$('input[name="radiogroup"]').click(function()
{
$('#amount').val($(this).val())
})
