Remove Element

Copy linkTweet thisAlerts:
Jul 28.2005

Hi all,

on my page i add emelents when a button is pressed using:

var row = document.createElement(“TR”);
var cell1 = document.createElement(“TD”);
var inp1 = document.createElement(“select”);

I would also like to be able to remove these elements on the click of a button.

Is this possible?

Thanks

@KorJul 28.2005 — if they are nested, it is enough to remove the element which is the parent of the others... cam we see the code?

@alexjamesthomasauthorJul 28.2005 — var inp2 = document.createElement("INPUT");

inp2.setAttribute("type","text");

inp2.setAttribute("size","5");

inp2.setAttribute("name","qty"+x);

cell2.appendChild(inp2);

row.appendChild(cell2);

tbody.appendChild(row);

I have shown the second element as the first is a selection box, therfore the code is huge.

U might have use loops and subroutine functions to shorten it.

still I have not enough data to help you properly

Anyway, I guess that you want to remove a row... Probably you need a button in each row, at the end of the row. If so, have a look at one of my elder works, maybe it will help you.
