Javascript - Update Input Fields (Not doing anything)


#1

Hello,

I am trying to add dynamic price calculations to a webflow form but am having some problems with my latest change. The code was working perfectly (in jsbin) when calculating and updating html labels but now that I want to update form inputs instead it does not do anything.

I have 4 inputs below:

    <div class="priceblock w-clearfix" id="PriceBlock">
      <h4>Payment Due</h4>
      <input class="readonlyprices text-field w-input" data-name="ClassPricePerWeek" id="ClassPricePerWeek" maxlength="256" name="ClassPricePerWeek" placeholder="Cost per week:" type="text">
      <input class="readonlyprices text-field w-input" data-name="SubTotal" id="SubTotal" maxlength="256" name="SubTotal" placeholder="Subtotal:" type="text">
      <input class="readonlyprices text-field w-input" data-name="Discount" id="Discount" maxlength="256" name="Discount" placeholder="Discount:" type="text">
      <input class="readonlyprices text-field w-input" data-name="TotalToPay" id="TotalToPay" maxlength="256" name="TotalToPay" placeholder="Total Cost:" type="text">
    </div>

which I am trying to update with document.getElementById("Discount").value

Is there issues with the javascript? (it does not error)
(Can't embed jsbin so here is jsfiddle)

hmm after playing with the code for another part of the site I have noticed that
onclick="calculateTotal()" had gone missing as I handcoded into the exported html

I can not get onclick attribute working for some reason. it says its reserved.
What do I need to do?
