javascript - How do you get two divs have the same borderRadius? -

is right way match 2 divs?

var div2 = document.getelementsbyclassname("div2"); div2.style.borderradius = "100px"  document.getelementbyid("div1").style.borderradius = div2.style.borderradius; 

just newbie @ javascript.

just comment on code, document.getelementsbyclassname() returns htmlcollection, not single dom element. should use document.getelementbyid() or document.queryselector() if you're trying 1 element.

and don't want use js add styling, unless styling want use dynamic. case, should use css file , add class:

.round-border {   border-radius: 100px; } 

if still want use js add class instead of putting in html, can following:

document.getelementbyid("div1").classlist.add('round-border'); document.getelementbyid("div2").classlist.add('round-border'); 

this assuming gave html elements correct id names.

but said, because using static value of 100px, make more sense add class elements in html file.
