这是我的代码。现在我正在使用类col-sm-6更改div的属性，单击一个按钮，使用jquery转动display：none。单击另一个按钮我将其更改回块，但模式不会打开。背景变暗但窗口无法打开。基本上最外层的div显示：none然后显示：block。但模式永远不会改变。什么是可能的解决方案。提前谢谢。
<div class="col-sm-6 col-md-4" id="challange">

如果您愿意，可以尝试使用此代码。
<?php
interface BookOffer {
function generateCoupon();
function generateDiscount();
}
class VintageBookOffer implements BookOffer {
function generateCoupon() {
return "VINTAGECOUPONCODE";
}
function generateDiscount() {
return 10.0;
}
}
class NewBookOffer implements BookOffer {
function generateCoupon() {
return "NEWBOOKCOUPONCODE";
}
function generateDiscount() {
return 5.0;
}
}
class OfferGenerator {
function generateOffer($bookType) {
if($bookType == "vintage") {
$bookObject = new VintageBookOffer();
}
else if($bookType == "newbook") {
$bookObject = new NewBookOffer();
}
return $bookObject;
}
}
$bookType1 = "vintage";
$bookType2 = "newbook";
$offerGenerator = new OfferGenerator();
$bookOffer1 = $offerGenerator->generateOffer($bookType1);
$bookOffer2 = $offerGenerator->generateOffer($bookType2);
echo "You chose book type " . $bookType1 . ". Your coupon code is " . $bookOffer1->generateDiscount() . ", and your discount is " . $bookOffer1->generateCoupon();
echo "You chose book type " . $bookType2 . ". Your coupon code is " . $bookOffer2->generateDiscount() . ", and your discount is " . $bookOffer2->generateCoupon();
?>
