jquery HOWTO select a node and clone it ,then remove a button finally insert into another node

below is part of html code

<div id="test1"><span><input type='text' name='add'/><input type='text' name='del'/><span></div>

<div id="container"></div>

i tried to use jquery to clone #test1 node and remove the add button then add the result to #container i tried write the code like belows,but it seems didn't work

$("#test1").clone().remove("input[name='add']").appendTo("#container")

hope someone could help,i have re-edited the question

How about this?

var t1 = $("#test1").clone();
$("input[name='add']", t1).remove();
$(t1).appendTo("#container");

$(':button').remove(); or $('input[type="button"]').remove() will probably do what you're looking for.

One way is to use replace function:

var str = html.replace("<input type='text' name='add'/>", "");

Result:

<div><span><input type='text' name='del'/>

If you have more than one of those instances, you can use regex with /g modifier:

var str = html.replace(/<input type='text' name='add'\/>/g, "");

Result:

<div><span><input type='text' name='del'/>
