Auto refresh based on drop down selection value (javascript/html) -

how can make page continuously refresh (auto-refresh) based on value selected drop down menu? googling, have far. please refer code below.

<form>  update interval (in seconds):  <select name="interval" id="interval">  <option value="5">10</option>  <option value="10">10</option>  <option value="15">15</option>  <option value="20">20</option>  </select>  </form>   <script type="text/javascript"> window.settimeout('window.location="";', document.getelementbyid('interval').value*1000); </script> 

the problem facing right now, page only refreshes in 5 seconds interval (first selection in drop down), no matter value selected. relative new html , javascript, can this.

you need on change of select dropdown, otherwise based on selected value on page load(5 in sample code)

<form>     update interval (in seconds):     <select name="interval" id="interval" onchange="window.settimeout(function(){ document.location.reload(true); }, this.options[this.selectedindex].value*1000);">      <option value="" disabled selected>make selection</option>      <option value="5">5</option>       <option value="10">10</option>       <option value="15">15</option>       <option value="20">20</option>     </select>   </form>
