我有网上商店,我希望用户通过更改glyphicon-shopping-cart颜色来了解产品是否已经在购物车中。这是我尝试过的:
´´´
$.ajax({
type: 'GET',
url: '/api/Selections',
dataType: 'json',
headers: {
'Authorization': 'Bearer ' + localStorage.getItem('accessToken')
},
success: function (data) {
$.each(data, function (i, val) {
if (val.Language == 'Suomi' && val.Season == '1/2020') {
//luodaan taulukko, johon arvot tuodaan halutuista sarakkeista
selection +=
'<tr >' +
"<td hidden>" + val.BookID + "</td>" +
"<td>" + val.ISBN + "</td>" +
"<td>" + val.Author + "</td>" +
"<td>" + val.BookName + "</td>" +
"<td>" + val.Publisher + "</td>" +
"<td>" + val.Price + "€ </td>" +
"<td><a href='#'><span class='glyphicon glyphicon-shopping-cart'></span></a></td>" +
"<td id='inCart'></td>" +
'</tr>';
// Change glyphicon color if product is in cart
$(function () {
$.ajax({
type: 'GET',
url: '/api/carts',
dataType: 'json',
success: function (cart) {
$.each(cart, function (i, cartdata) {
if (cartdata.CompanyID == JSON.parse(localStorage.getItem('userName')) && cartdata.IsInCart == true && val.ISBN == cartdata.ISBN) {
$(".glyphicon-shopping-cart").css("color", "#29d646");
// This in not working, all glyphicons change color
}
})
}
})
});
}
});
´´´
此代码的问题是表中的所有字形都改变颜色,而不仅是购物车ISBN与表ISBN匹配的行。现在,我将在单击按钮时执行此操作,但是当用户转到另一个页面时,这些颜色会消失。我尝试使用localStorage,但那里存在同样的问题。怎么办还是有其他方法可以做到这一点?
您正在选择所有glyphicon-shopping-cart来匹配当前图标,您可以插入数据ID并进行匹配,因为我看不到val.ISBN和cartdata.ISBN的结果,我将举个例子来说明它的外观
"<td><a href='#'><span class='glyphicon glyphicon-shopping-cart' data-id="+val.ISBN+"></span></a></td>" +
if (cartdata.CompanyID == JSON.parse(localStorage.getItem('userName')) && cartdata.IsInCart == true && val.ISBN == cartdata.ISBN) {
$(".glyphicon-shopping-cart[data-id="+val.ISBN+"]").css("color", "#29d646");
