Question

I need to find and replace a div with the id left_s with a div with id=newdiv. Also, I need to get the height and width of the previous div left_s and apply it to the new div with id=newdiv.

I’ve got this code, but it’s not working:

$('#left_s').replaceWith('<div id="newdiv" </div>');
var w = $("#newdiv").width();
$(".left_s").width(w);

///////after “.replaceWith” i can’t get height and width from div “left_s” and apply it to “newdiv”.

Answer 1

Try:

$("body").append('<div id="newdiv"></div>');
$(".left_s").width($("#newdiv").width());

You can fix up the code so it matches your purpose, but the key is appending the element into the DOM. Otherwise, it doesn’t have a computed width/height.
