我在这个应用程序中有三个问题。
第一个问题是，在我们打开应用后关闭应用时，show按钮的名称不会更改为“show offer”。
第二次，该应用不会阻止用户点击第二个和第三个按钮。他只能点击一个优惠，但现在用户可以点击每个优惠。
第三次，用户可以通过点击一次突出显示新的优惠，然后他可以隐藏突出显示，但不能再次突出显示它，从不。感谢任何帮助。
//// hide offer before the Dom is loaded
//$('ul').hide()
$(document).ready(function() {
function showHideOffer() {
$('ul').slideToggle();
}
//click to show offers
$('.card').on('click', '.showOffers', showHideOffer, function() {
$('.showOffers').html('Hide Offers');
});
//click to hide offers - change name to show offers doesn't work!!
$('.card').on('click','.showOffers', showHideOfferfunction() {
$('.showOffers').html('Show Offers');
});
// click to book, to show info and close button and span
$('li').on('click', 'button', function(){
var offerName = $(this).closest('.tour').data('name');
var offerPrice = $(this).closest('.tour').data('price')
var message = $('<ol class="breadcrumb"><li class="breadcrumb-item active" style="color:#3CB371">Success! You have booked '+offerName+' offer for '+offerPrice+'!</li></ol>');
$(this).closest('.tour').append(message);
$(this).prev().closest('.details').remove();
$(this).remove();
});
// filter new offers by clicking a "new" button
$('#buttons').on('click','.filterNew', function() {
$('.tour').filter('.newOffer').addClass('highlightnew');
$('.highlightpopular').removeClass('highlightpopular');
//click second time and the highlight is hidden
$('#buttons').on('click', '.filterNew', function() {
$('.highlightnew').removeClass('highlightnew');
});
});
// filter by popular offers
$('#buttons').on('click', '.filterPopular', function() {
$('.tour').filter('.popular').addClass('highlightpopular');
$('.highlightnew').removeClass('highlightnew');
});

第一期解决：在此结帐： 将代码更改为
$('.card').on('click', '.showOffers', showHideOffer, function() {
//$('.showOffers').html('');
$(this).text( $(this).text() == 'Hide Offers' ? "Show Offers" : "Hide Offers");
});
代替：
$('.card').on('click', '.showOffers', showHideOffer, function() {
$('.showOffers').html('Hide Offers');
});
//click to show offers
$('.card').on('click', '.showOffers', showHideOffer, function() {
//$('.showOffers').html('');
$(this).text( $(this).text() == 'Hide Offers' ? "Show Offers" : "Hide Offers");
});
//click to hide offers - change name to show offers doesn't work!!
$('.card').on('click','.showOffers', showHideOffer);
// click to book, to show info and close button and span
$('li').on('click', 'button', function(){
var offerName = $(this).closest('.tour').data('name');
var offerPrice = $(this).closest('.tour').data('price')
var message = $('<ol class="breadcrumb"><li class="breadcrumb-item active" style="color:#3CB371">Success! You have booked '+offerName+' offer for '+offerPrice+'!</li></ol>');
$(this).closest('.tour').append(message);
$(this).prev().closest('.details').remove();
$(this).remove();
});
// filter new offers by clicking a "new" button
$('#buttons').on('click','.filterNew', function() {
$('.tour').filter('.newOffer').addClass('highlightnew');
$('.highlightpopular').removeClass('highlightpopular');
//click second time and the highlight is hidden
$('#buttons').on('click', '.filterNew', function() {
$('.highlightnew').removeClass('highlightnew');
});
});
// filter by popular offers
$('#buttons').on('click', '.filterPopular', function() {
$('.tour').filter('.popular').addClass('highlightpopular');
$('.highlightnew').removeClass('highlightnew');
});
function showHideOffer() {
$('ul').slideToggle();

To Resolve your first issue modify your function like below
var ValuesShowOrHidden = 0;
$('.card').on('click', '.showOffers', showHideOffer, function () {
if (ValuesShowOrHidden == 0) {
$('.showOffers').html('Hide Offers');
ValuesShowOrHidden = 1;
}
else if (ValuesShowOrHidden==1) {
$('.showOffers').html('Show Offers');
ValuesShowOrHidden = 0;
}
});
对于第二期，请在函数中尝试以下修改
$('li').on('click', 'button', function () {
var offerName = $(this).closest('.tour').data('name');
var offerPrice = $(this).closest('.tour').data('price')
var message = $('<ol class="breadcrumb"><li class="breadcrumb-item active" style="color:#3CB371">Success! You have booked ' + offerName + ' offer for ' + offerPrice + '!</li></ol>');
$(this).closest('.tour').append(message);
$(this).prev().closest('.details').remove();
$(this).remove();
$('li').unbind("click");
});
