Enter an input value with greasemonkey

Question

I have some input values contained within a bunch of divs and a form. I have a limited knowledge of js and would like to use greasemonkey to set the values when the page loads.

The following shows the order of divs and forms to get to the value.

<div data-role="page" id="finalTest">                    
  <div data-role="content">
    <form class="cmxform" id="ftForm">
      <div id="finalTestForOtherDiv" >
        <div data-role="fieldcontain" class="special-spacing">
                <div class="input-div">
                    <label id="finalTestBeforeAcTgrLabel" for="finalTestBeforeAcTg" data-insight="true" 
                        class="mandatory" data-default="mandatory"><img class="label-image" alt="" src="../Images/icon-alert.png" />AC V (T/G):</label>
                    <input type="text" id="finalTestBeforeAcTg" name="finalTestBeforeAcTg" value="" style="width:100px; display:inline-block;" 
                        data-bind="binder.BeforeAcTg"  data-bind-action-when-hidden="Ignore" />
                    <span class="ui-content" style="padding-left:7px;">V</span>
                    <div class="error-message"><ul></ul></div>

                </div>

Here is the script I've tried using but does nothing.

// ==UserScript==
// @name    Final Test
// @description Final test results
// @include https://techaccess.ad.qintra.com/WorkJobs/WorkJobs.aspx#finalTest
// ==/UserScript==

document.getElementById("finalTestBeforeAcTg").value = "0.00";

Answer 1

document.getElementById("finalTestBeforeAcTg").value = "your value";
