Div tag target attribute

I would like to add a target attribute to a div tag (see code below) so that the page "index.html" opens in the same page i.e target_self

  <div id="home" style="cursor:pointer;
      开发者_C百科           "href="javascript:void(0)" 
                 onclick="window.open('index.html')"></div>

You should change from window.open to window.location.href =
