我有一块克隆三个字段的代码,但是当克隆这三个字段时,它也克隆了它里面输入的文本,有没有办法清除里面的内容当它被克隆时,它的领域是什么?克隆一个字段而不克隆文本以及
$(document).ready(function() {
$('#btnAdd').click(function() {
var num = $('.clonedSection').length;
var newNum = new Number(num + 1);
var newSection = $('#clonedSection' + num).clone().attr('id', 'clonedSection' + newNum);
newSection.children(':first').children(':first').attr('id', 'name' + newNum).attr('name', 'name' + newNum);
newSection.children(':nth-child(2)').children(':first').attr('id', 'age' + newNum).attr('name', 'age' + newNum);
newSection.children(':nth-child(3)').children(':first').attr('id', 'school' + newNum).attr('name', 'school' + newNum);
$('.clonedSection').last().append(newSection);
$('.clonedSection').last().val(ping);
$('#btnDel').attr('disabled','');
if (newNum == 2)
$('#btnAdd').attr('disabled','disabled');
});
$('#btnDel').click(function() {
var num = $('.clonedSection').length; // how many "duplicatable" input fields we currently have
$('#clonedSection' + num).remove(); // remove the last element
// enable the "add" button
$('#btnAdd').attr('disabled','');
// if only one element remains, disable the "remove" button
if (num-1 == 1)
$('#btnDel').attr('disabled','disabled');
});
$('#btnDel').attr('disabled','disabled');
});
Thanx提前!
为什么你要问的确切同样的问题两次? http://stackoverflow.com/questions/3467457/cloning-a-field-with-text-in-it-clones-text-as-well – 2010-08-12 12:27:28
没理由,是个意外! :/ – Odyss3us 2010-08-13 10:42:04
