javascript - Changing upload placeholder after chose file -

-

i have code currently:

html:

<div class="row upload"> <form enctype="multipart/form-data" action="" method="post" class="col-md-12">  <label for="file" class="filebutton">no file has been selected</label>  <input style="opacity:0" type="file" name="file" id="file" />  </form>   </div><!--end of row upload-->

css:

label {     background-color: #eeeeee;     width: 500px;     height:50px;     font-weight: normal;     color: #777777;     padding:20px;     margin-top: 10px;  }

as can see, when file chosen, placeholder still remains same. want placeholder file directory when file chosen.

fiddle: http://jsfiddle.net/7rtj5/

test :

html :

<div class="row upload">     <form enctype="multipart/form-data" action="" method="post" class="col-md-12">         <input id="uploadfile" placeholder="choose file" disabled="disabled" />         <label for="file" class="filebutton">no file has been selected</label>         <input style="opacity:0" type="file" name="file" id="file" />     </form>    </div><!--end of row upload-->

js:

document.getelementbyid("file").onchange = function () {     document.getelementbyid("uploadfile").value = this.value; };
