一世我不清楚你到底想要什么 –

你想增加名字？然后使用'++'方法 –

是的，我想增加名称 – Rtra

我改变一小片的代码固定它

var formItem; 
var counter = 0; 
$(document).ready(function() { 
    //Clone and remove your div instead of hiding it 
formItem = $('.ScheduleextraPartTemplate').clone(); 
    formItem.find('[name^=txtSchedule]')[0].name = "txtSchedule" + counter; 
    formItem.find('[name^=txtScheduleAmountPay]')[0].name = "txtScheduleAmountPay" + counter; 
$('.ScheduleextraPartTemplate').remove(); 
    formItem.addClass('clone clone-1'); 

$('#Schedulecontainer').append(formItem); 
}); 

$(document).on('click', '#ScheduleaddRow', function() { 
    var lens = counter++; 
    var cloneForm = $('.clone').last().clone(); 
    var cloneNum = $('.clone').length; 
    cloneForm.removeClass('clone-'+cloneNum).addClass('clone-' + (cloneNum+1)); 
    var date = cloneForm.find('[name^="txtSchedule"]').val(); 
    cloneForm.find('[name^="txtSchedule"]').val(addOneMonth(date)); 
    cloneForm.find('[name^=txtSchedule]')[0].name = "txtSchedule" + (lens+1); 
    cloneForm.find('[name^=txtScheduleAmountPay]')[0].name = "txtScheduleAmountPay" + (lens+1); 

$('#Schedulecontainer').append(cloneForm); 
}) 

function addOneMonth(date) { 
var d = new Date(date); 
d.setMonth(d.getMonth() + 1); 
return d.getFullYear() + '-' + ("0" + ((d.getMonth() + 1))).slice(-2) + '-' + ("0" + (d.getDate())).slice(-2); 
}
