radio or checkbox

[Dormilich]

not necessarily, you can define buttons using <button>, or you can write your script in a way, that it doesn’t matter. you may not even require a button.

[colinod]

could i script it so if you clicked on a radio that is selected it would set it as unselected

[Dormilich]

yes, you can.

[colinod]

ok

My calculations are set with this code

function calculate(f)
{
var nums = f.num;
var ntext = f.num;
var result = 0;
for(var i=0;i<nums.length;i++)
{
if(nums[i].checked)
{
result+=parseFloat(ntext[i].value);
}
}
f.answer.value=Number(result).toFixed(2);

will a click event change this?

[Dormilich]

before I answer that … make an educated guess.

hint: check your event handlers

[colinod]

Not sure what you mean and then realised the page i was editing somehow had and old calculation on it and now the page will not add the totals using the calculation a was using?

[Dormilich]

… confused

Finally sorted the site out, dont know what happened there but i now have the following for my calculations

function UpdateCost() {
  var sum = runtotal;
  var gn, elem;
  for (i=0; i<205; i++) {
    gn = 'id'+i;
    elem = document.getElementById(gn);
    if (elem.checked == true) { sum += Number(elem.value); }
  }
   parseFloat(sum);
  document.getElementById('total').value = sum.toFixed(2);

What i was thinking was could i have another function something like this

function check() {
  var gn, elem;
  for (i=0; i<205; i++) {
    gn = 'id'+i;
    elem = document.getElementById(gn);
    if (elem.checked == true) 
then
elem.checked == false

else elemchecked==true
  }
then call my calculate funtion
}

this is probably way too complicated and i know it wont work

[colinod]

i seem to be getting there, i now have the following called by double click and this unchecks 1 radio and removes from the total, what i cant figure out is how to get this in a function that works on a single click

function checkbutt(i) 
{
	var gn;
	gn = 'id'+i;
	{
    document.getElementById(gn).checked = false;
	}
	UpdateCost();
}

note: parseFloat(sum) ; (line #9) still does nothing.
