javascript - highlighting section of website after redirect -

so i've got lightbox on website there's link within.

when user clicks link gets taken domain.com/sub#target

the targeted area quite small it's important highlight it.

this how far i've gotten:

jsfiddle: http://jsfiddle.net/mt9z6d7k/1/

function focuss (id) {         var divs = document.getelementsbyid('u_0_3');          var count = divs.length;          (var = 0; < count; i++) {             if (divs[i].classname == 'focus_div'){                 divs[i].onclick = highlight(id);             }         } }  function highlight(id) {      document.getelementbyid(id).style.bordercolor = '#ff0000'; } 

the solution must in javascript unfortunately. if me appreciate much!

document.getelementsbyid not js function.
if want target multi elements id, use document.queryselectorall('#u_0_3').

i must warn you, valid html doesn't allow repeat same id on multiple elements. suggest use class, focus_div above, doing document.queryselectorall('.focus_div') or document.getelementsbyclassname('focus_div').

here's working fiddle using multiple ids: http://jsfiddle.net/7g4t9yxo/1/

notice add focuss('u_0_3'); end activate behavior.
