I hop somebody here is able to help me out.
I would like to show a hidden div tag if a textfield is set to a value.

I tried to solve the problem by myself, but it's not working, can you help me out here?

Thanks in advance!

```js
<script type="text/javascript">
                    if(document.getElementById("art").value == "test"){
                    document.getElementById("divDetails").style.display='block';
                    }
                    </script>
```

```html
<input type="text" name="art" id="art" value="" class="form-control" style="height: 3em; font-size: 9px;"> 
<div style="display: none" id="divDetails">Here is the hidden text</div>
```
