使用 jquery 添加到购物车
我正在使用这个 jquery 脚本:
$(document).ready(function(){
$("#basketItemsWrap li:first").hide();
$(".productPriceWrapRight a img").click(function() {
var productIDValSplitter = (this.id).split("_");
var productIDVal = productIDValSplitter[1];
var productX = $("#productImageWrapID_" + productIDVal).offset().left;
var productY = $("#productImageWrapID_" + productIDVal).offset().top;
if( $("#productID_" + productIDVal).length > 0){
var basketX = $("#productID_" + productIDVal).offset().left;
var basketY = $("#productID_" + productIDVal).offset().top;
} else {
var basketX = $("#basketTitleWrap").offset().left;
var basketY = $("#basketTitleWrap").offset().top;
}
var gotoX = basketX - productX;
var gotoY = basketY - productY;
var newImageWidth = $("#productImageWrapID_" + productIDVal).width() / 3;
var newImageHeight = $("#productImageWrapID_" + productIDVal).height() / 3;
$("#productImageWrapID_" + productIDVal + " img")
.clone()
.prependTo("#productImageWrapID_" + productIDVal)
.css({'position' : 'absolute'})
.animate({opacity: 0.4}, 100 )
.animate({opacity: 0.1, marginLeft: gotoX, marginTop: gotoY, width: newImageWidth, height: newImageHeight}, 1200, function() {
$(this).remove();
$("#notificationsLoader").html('<img src="images/loader.gif">');
$.ajax({
type: "POST",
url: "funzioni-carrello.asp",
data: { productID: productIDVal, action: "addToBasket"},
success: function(theResponse) {
if( $("#productID_" + productIDVal).length > 0){
$("#productID_" + productIDVal).animate({ opacity: 0 }, 500);
$("#productID_" + productIDVal).before(theResponse).remove();
$("#productID_" + productIDVal).animate({ opacity: 0 }, 500);
$("#productID_" + productIDVal).animate({ opacity: 1 }, 500);
$("#notificationsLoader").empty();
} else {
$("#basketItemsWrap li:first").before(theResponse);
$("#basketItemsWrap li:first").hide();
$("#basketItemsWrap li:first").show("slow");
$("#notificationsLoader").empty();
}
}
});
});
});
$("#basketItemsWrap li img").live("click", function(event) {
var productIDValSplitter = (this.id).split("_");
var productIDVal = productIDValSplitter[1];
$("#notificationsLoader").html('<img src="images/loader.gif">');
$.ajax({
type: "POST",
url: "funzioni-carrello.asp",
data: { productID: productIDVal, action: "deleteFromBasket"},
success: function(theResponse) {
$("#productID_" + productIDVal).hide("slow", function() {$(this).remove();});
$("#notificationsLoader").empty();
}
});
});
});
然后我有这样的函数调用:
<div id="basketWrap">
<div id="basketTitleWrap">
<h2>Carrello </h2>
</div>
<div id="basketItemsWrap">
<ul>
<li></li>
<%
'dim getBasket
getBasket() %>
</ul>
</div>
</div>
我如何修改它,以便如果篮子是空的,它会显示一条消息“您的篮子是空的”。当您添加第一个产品时,该信息会消失;如果您从购物篮中删除所有产品,该信息会重新出现
i'm using this jquery script:
$(document).ready(function(){
$("#basketItemsWrap li:first").hide();
$(".productPriceWrapRight a img").click(function() {
var productIDValSplitter = (this.id).split("_");
var productIDVal = productIDValSplitter[1];
var productX = $("#productImageWrapID_" + productIDVal).offset().left;
var productY = $("#productImageWrapID_" + productIDVal).offset().top;
if( $("#productID_" + productIDVal).length > 0){
var basketX = $("#productID_" + productIDVal).offset().left;
var basketY = $("#productID_" + productIDVal).offset().top;
} else {
var basketX = $("#basketTitleWrap").offset().left;
var basketY = $("#basketTitleWrap").offset().top;
}
var gotoX = basketX - productX;
var gotoY = basketY - productY;
var newImageWidth = $("#productImageWrapID_" + productIDVal).width() / 3;
var newImageHeight = $("#productImageWrapID_" + productIDVal).height() / 3;
$("#productImageWrapID_" + productIDVal + " img")
.clone()
.prependTo("#productImageWrapID_" + productIDVal)
.css({'position' : 'absolute'})
.animate({opacity: 0.4}, 100 )
.animate({opacity: 0.1, marginLeft: gotoX, marginTop: gotoY, width: newImageWidth, height: newImageHeight}, 1200, function() {
$(this).remove();
$("#notificationsLoader").html('<img src="images/loader.gif">');
$.ajax({
type: "POST",
url: "funzioni-carrello.asp",
data: { productID: productIDVal, action: "addToBasket"},
success: function(theResponse) {
if( $("#productID_" + productIDVal).length > 0){
$("#productID_" + productIDVal).animate({ opacity: 0 }, 500);
$("#productID_" + productIDVal).before(theResponse).remove();
$("#productID_" + productIDVal).animate({ opacity: 0 }, 500);
$("#productID_" + productIDVal).animate({ opacity: 1 }, 500);
$("#notificationsLoader").empty();
} else {
$("#basketItemsWrap li:first").before(theResponse);
$("#basketItemsWrap li:first").hide();
$("#basketItemsWrap li:first").show("slow");
$("#notificationsLoader").empty();
}
}
});
});
});
$("#basketItemsWrap li img").live("click", function(event) {
var productIDValSplitter = (this.id).split("_");
var productIDVal = productIDValSplitter[1];
$("#notificationsLoader").html('<img src="images/loader.gif">');
$.ajax({
type: "POST",
url: "funzioni-carrello.asp",
data: { productID: productIDVal, action: "deleteFromBasket"},
success: function(theResponse) {
$("#productID_" + productIDVal).hide("slow", function() {$(this).remove();});
$("#notificationsLoader").empty();
}
});
});
});
Then i've the function call like this:
<div id="basketWrap">
<div id="basketTitleWrap">
<h2>Carrello </h2>
</div>
<div id="basketItemsWrap">
<ul>
<li></li>
<%
'dim getBasket
getBasket() %>
</ul>
</div>
</div>
How can i modify this so that if the basket is empty it displays a message saying “your basket is empty.” This disappears when you add the first product, and would reappear if you removed all products from your basket

从空篮子开始,如下所示:
当您的物品列表为空时,您将
display:none;
应用于#itemlist
,如果它已满display: none;
到#empty
div 和display:block;
到#itemlist
。当您使用类似
class="hidden"
的内容时,您只需切换类即可。另外,您可以通过
.html()
操作购物篮的内部 HTML。编辑:
使用上面给出的标记,添加到您的函数中:
以下代码:(
您也可以使用一些转换。)
并在 add-product 函数中添加 ajax 调用的成功部分:
start out with you empty basket, something like this:
when your itemlist is empty, you apply
display:none;
to the#itemlist
, if its filleddisplay:none;
to the#empty
div anddisplay:block;
for the#itemlist
.When you use something like
class="hidden"
you simply could toggle the classes.ALtnernatively, you could manipulate the innerhtml of your basket via
.html()
.EDIT:
with the markup given above, add to your function:
the following code:
(you could use some transition, too.)
And to the success-part of you ajax call in the add-product function you add:
