Javascript Question

Jquery .val() dont work properly with Material Design Bootstrap

I'm using Material Design Bootstrap to style and do something nice with the inputs placeholder.

<input id="ConfigName" class="form-control floating-label" placeholder="Name" type="text">

But if I try to add/change some text to the input with jquery it doesn't work correctly.

$('#ConfigName').html("testersres"); // dont work
$('#ConfigName').text("testersres"); // dont work
$('#ConfigName').val("testersres"); //Placeholder and "testersres" is placed on top of each other

I'm using the floating label, second from the top @here

Can someone tell me whats wrong, or how I can fix it?

Here is an image with the problem:

When you are assigning the value, in js you need to remove class empty from the corresponding field.

$('#ConfigName1').removeClass("form-control empty");
* {
  box-sizing: border-box;
.header-panel {
  background-color: #009587;
  height: 144px;
  position: relative;
  z-index: 3;
.header-panel div {
  position: relative;
  height: 100%;
.header-panel h1 {

  padding-left: 35px;
.menu {
  overflow: auto;
  padding: 0;

.menu ul {
  padding: 0;
  margin: 7px 0;
.menu ul li {
  list-style: none;
