[英]Dynamically Change select option when checkboxes are selected
更改單擊復選框時的選擇選項,我有8個復選框的列表,它動態地計數已選中的復選框,例如,如果我單擊1個復選框,它將顯示Number of Credits Selected:1,如果我單擊2個復選框,它將顯示將會顯示“所選的學分數量”:2並很快,
在復選框下面,我具有選擇選項。我想在選中復選框時動態更改選擇選項。例如:如果我單擊兩個復選框,則我的選擇選項應更改為2 selected,依此類推。
有人可以幫助我實現這一目標!
謝謝!

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;
});
});
只需將以下行添加到您的click event
$('.form-control').val(total + " selected");
因此,您更新的代碼將是:
$('input[type="checkbox"]').click(function() {
var total = ($('.no_of_credits:checked').length) + 0;
$(".print_no_of_credits").html("<h1>Number Of Credits Selected : " + total + "</h1>").length;
$('.form-control').val(total + " selected");
});
UPDATED FIDDLE
更新資料
您可以將var total
計算修改為
var total=$('.no_of_credits:checked').length
