更改单击复选框上的选择选项，我有8个复选框的动态列表，它会选中复选框，例如，如果我单击1复选框，它将显示所选的积分数：1，如果我点击2复选框将显示所选的积分数：2，很快，
在复选框下方我有选择选项，我想在选中复选框时动态更改选项 例如：如果我单击两个复选框，我的选择选项应更改为2选择，依此类推。
有人可以帮助我实现它！
谢谢！

JQUERY
$(document).ready(function()
{
$('input[type="checkbox"]').click(function()
{
var total = ($('.no_of_credits:checked').length)+0;
$(".print_no_of_credits").html( "<h1>Number Of Credits Selected : "+total+"</h1>" ).length;
});
});
答案 0 :(得分：2)
只需将以下行添加到click event
$('.form-control').val(total + " selected");
所以你的更新代码是：
$('input[type="checkbox"]').click(function() {
var total = ($('.no_of_credits:checked').length) + 0;
$(".print_no_of_credits").html("<h1>Number Of Credits Selected : " + total + "</h1>").length;
$('.form-control').val(total + " selected");
});

UPDATED FIDDLE
<强>更新
您可以将var total计算修改为
var total=$('.no_of_credits:checked').length
