Direct link to the content

I have a page http://bartle96.narod2.ru/demo.html there are 4 links开发者_JAVA百科 to the hidden content

Is it possible to make a direct link to the content such as "dolphin".

So that when you click on a link http://bartle96.narod2.ru/demo.html#delfin immediately opened a photo with a dolphin

Yes, you can define and open needed content on onload event.

Check this post where you can find the same behaviour:

jQuery when pointed to a link should show a div that's hidden by default

You can get the hash value using window.location.hash. Then set the pic you want based on the value.

window.onload = function() {
  var pic = window.location.hash;
  if ( pic === "#delfin" ) {
    // Show picture of dolphin
  }
}
