Javascript 克隆表行,将随机或序列号附加到ID
所以我有这个密码Javascript 克隆表行,将随机或序列号附加到ID,javascript,jquery,Javascript,Jquery,所以我有这个密码 $('input.clone').live('click', function(){ //put jquery this context into a var var $btn = $(this); //use .closest() to navigate from the buttno to the closest row and clone it var $clonedRow = $btn.closest('tr').clone(); //ap
$('input.clone').live('click', function(){
//put jquery this context into a var
var $btn = $(this);
//use .closest() to navigate from the buttno to the closest row and clone it
var $clonedRow = $btn.closest('tr').clone();
//append the cloned row to end of the table
//clean ids if you need to
$clonedRow.find('*').andSelf().filter('[id]').each( function(){
//clear id or change to something else
this.id += '_clone';
});
//finally append new row to end of table
$btn.closest('tbody').append( $clonedRow );
});
问题是,我克隆的每一行都会被命名为which\u clone
我该如何编写它,以便每次运行该函数时,它都会选择一个随机的或更理想的序列号来附加到“\u clone”的id isntead中
将以字符串形式为您提供一个介于0和999999之间的随机数。为什么不使用表中的行数
$clonedRow.find('*').andSelf().filter('[id]').each( function(){
//clear id or change to something else
var rowCount = $btn.closest('tr').siblings().length;
this.id += 'row_' + rowCount;
});
身份证是从什么开始的?如果它们可以是row_x,那么当我从数据库中提取它们时会很有帮助,我将使用php为它们命名序列号。你确定只有tr才有id吗?否则,由于我的+size()比.length慢(size()实际上在内部调用了.length),所以这段代码将开始复制这个名称
$clonedRow.find('*').andSelf().filter('[id]').each( function(){
//clear id or change to something else
var rowCount = $btn.closest('tr').siblings().length;
this.id += 'row_' + rowCount;
});
$('input.clone').live('click', function(){
var $btn = $(this);
var $clonedRow = $btn.closest('tr').clone();
$clonedRow.find('*').andSelf().filter('[id]').each( function(){
this.id += '_clone' + $(this).siblings().size();
});
//finally append new row to end of table
$btn.closest('tbody').append( $clonedRow );
});
