this will help If you use the jquery library you can use the .mousemove(handler) function which looks something like this
code :
$( "#target" ).mousemove(function( event ) {
  var msg = "Handler for .mousemove() called at ";
  msg += event.pageX + ", " + event.pageY;
  $( "#log" ).append( "<div>" + msg + "</div>" );
});

I wish this help you I have these input fields, well 1 input text box, and then i have a drop down. Now what I want is when a user selects an option from the dropdown (this is the dropdown) , Add onchange listener to your markup:
code :
<select name="searchType" onchange="showFields(this)">
  <option value="all">All</option>
  <option value="music">Music</option>
  <option value="movie">Movies</option>
  <option value="tvShow">Tv Shows</option>
  <option value="musicVideo">Music Videos</option>
  <option value="audiobook">Audio Books</option>
  <option value="shortFilm">Short Films</option>
  <option value="podcast">Podcasts</option>
</select>
function showFields(select) {
  var field = select.options[select.selectedIndex].value;
  switch (field) {
    case "all":
      // show all fields
      break;
    case "music":
      // show music field
      break;
    // ... more cases
    default:
       // default handler
  }
}
var data = [
    {type:"music",link:"http://www.domain.com/music/",file:"music1.mp3"}

  ];
  // ...
  case "music":
    var targetSelect = document.getElementById('otherSelect');
    targetSelect.options.length = 0; // clear it if it already has values
    for (var i=0,imax=data.length; i<imax; i++) {
      if (data[i].type == "music") {

will be helpful for those in need I'm adding some javascript validation to a form. The form has fields that currently look like: , You can use the bracket notation for objects as well as arrays:
code :
theForm['Employee Full Name'].value == ""
foo.1 //foo['1']
foo.this-is-wrong //foo['this-is-wrong']
foo.bar.baz //although this looks correct, it's wrong if you actually wanted foo['bar.baz']
html form input javascript sum fields

fixed the issue. Will look into that further Your code is almost fine, just requires some little fixes : you were using the same name for the select "taxes" and the input "taxes" (now "ttaxes"), you assigned the value "yes" to the tax (I changed it by 19), finally, copy-pasted your own code to calculate discount (used to calculate taxes). Now you have only one thing to do : calculate the sum of both (total price). Here it is, the changes are pointed by commented arrows :
code :
<html>
  <body>
<table width="339" border="0" cellpadding="0">
  <tr>
    <td width="98">Taxes</td>
    <td width="115">Discount</td>
    <td width="118">Default price</td>
  </tr>
  <tr>
    <td><select class="select" name="taxes" onChange="updateInput()">
      <option value="no" selected>no taxes</option>
      <option value="19">19% taxes</option> <!-- <====================== -->
    </select></td>
    <td><select class="select" name="discount" onChange="updateInput()">
      <option value="5" selected>5% discount</option>
      <option value="10">10% discount</option>
      <option value="20">20% discount</option>
    </select></td>
    <td><input type="text" class="input140" name="cost" id="cost" value="1000"></td>
  </tr>
  <tr>
    <td>Price after discount</td>
    <td>Taxes</td>
    <td>Total Price to pay</td>
  </tr>
  <tr>
    <td><input type="text" name="price" value=""></td>
    <td><input type="text" name="ttaxes" value="0"></td> <!-- <====================== -->
    <td><input type="text" name="total" value="0"></td>
  </tr>
</table>
<script type="text/javascript">
function updateInput(){
    var discount = document.getElementsByName("discount")[0].value;
    var cost = document.getElementsByName("cost")[0].value;
    document.getElementsByName("price")[0].value = cost - (cost * (discount / 100));

    var taxes = document.getElementsByName("taxes")[0].value; // <======================
    if ( isNaN( taxes ) ) // IF "no taxes" IS SELECTED...
         document.getElementsByName("ttaxes")[0].value = 0;
    else { cost = document.getElementsByName("cost")[0].value;
           document.getElementsByName("ttaxes")[0].value = (cost * (taxes / 100));
         }

    document.getElementsByName("total")[0].value = 
      parseFloat( document.getElementsByName("price")[0].value ) +
      parseFloat( document.getElementsByName("ttaxes")[0].value );
}
</script>

javascript add html tag to all input required fields

javascript add html tag to all input required fields

I wish this helpful for you You can't insert the same span before all the fields, you should clone it using spanTag.cloneNode(true) for every input field.
code :
function addRequiredAttribute(buttonName) {
  var login = document.getElementById("login");
  var password = document.getElementById("password");
  var name = document.getElementById("name");
  var email = document.getElementById("email");

  var spanTag = document.createElement("span");
  spanTag.className ="required";
  spanTag.textContent ="example span text ";

  if(buttonName === "add") {
    login.setAttribute("required","required");
    login.parentNode.insertBefore(spanTag.cloneNode(true), login);
    password.setAttribute("required","required");
    password.parentNode.insertBefore(spanTag.cloneNode(true), password);
    name.setAttribute("required","required");
    name.parentNode.insertBefore(spanTag.cloneNode(true), name);
    email.setAttribute("required","required");
    email.parentNode.insertBefore(spanTag.cloneNode(true), email);
  } else {
    login.setAttribute("required","required");
    login.parentNode.insertBefore(spanTag, login);
  }
}

addRequiredAttribute('add');
<div>
  <input type="text" id="login" /><br/>
</div>
<div>
  <input type="password" id="password" /><br/>
</div>
<div>
  <input type="text" id="name" /><br/>
</div>
<div>
  <input type="email" id="email" />
</div>

I wish did fix the issue. You can clone the element on page load (outside of the function). This will ensure that the cloned element will be from its original states.
Please Note: The attribute id must be unique in a document. If you are going to refer the cloned element with that id then you will only get the first matched element. You can use class instead.
code :
var i = 0;
var original = document.getElementById('duplicater' + i);
var clone = original.cloneNode(true); // "deep" clone
function duplicate() {
    clone.id = "duplicater" + ++i; 
    original.parentNode.appendChild(clone);
}
