Question

我正在使用下面的脚本将产品添加到购物车并删除，其中我显示计数添加了多少和删除后剩余多少...在我的脚本中当我删除计数时没有显示并且刷新后的页数是显示我错过了逻辑......

// Cart add remove functions
var cart = {
    'add': function(product_id, quantity) {
        $.ajax({
            url: 'index.php?route=checkout/cart/add',
            type: 'post',
            data: 'product_id=' + product_id + '&quantity=' + (typeof(quantity) != 'undefined' ? quantity : 1),
            dataType: 'json',
            beforeSend: function() {
                $('#cart > button').button('loading');
            },
            complete: function() {
                $('#cart > button').button('reset');
            },          
            success: function(json) {
                $('.alert, .text-danger').remove();

                if (json['redirect']) {
                    location = json['redirect'];
                }

                if (json['success']) {
                    $('#content').parent().before('<div class="alert alert-success"><i class="fa fa-check-circle"></i> ' + json['success'] + '<button type="button" class="close" data-dismiss="alert">&times;</button></div>');

                    // Need to set timeout otherwise it wont update the total
                    setTimeout(function () {
                        $('#cart > button').html('<span id="cart-total"><i class="fa fa-shopping-cart"></i> ' + json['total'] + '</span>');
                    }, 100);

                    $('html, body').animate({ scrollTop: 0 }, 'slow');

                    $('#cart > ul').load('index.php?route=common/cart/info ul li');
                }
            }
        });
    },
    'update': function(key, quantity) {
        $.ajax({
            url: 'index.php?route=checkout/cart/edit',
            type: 'post',
            data: 'key=' + key + '&quantity=' + (typeof(quantity) != 'undefined' ? quantity : 1),
            dataType: 'json',
            beforeSend: function() {
                $('#cart > button').button('loading');
            },
            complete: function() {
                $('#cart > button').button('reset');
            },          
            success: function(json) {
                if( json['total']){
                    var total= json['total'];

                else{
                    var total="";
                }
                // Need to set timeout otherwise it wont update the total
                setTimeout(function () {
                    $('#cart > button').html('<span id="cart-total"><i class="fa fa-shopping-cart"></i> ' + json['total'] + '</span>');
                }, 100);

                if (getURLVar('route') == 'checkout/cart' || getURLVar('route') == 'checkout/checkout') {
                    location = 'index.php?route=checkout/cart';

                if (getURLVar('route') == 'checkout/cart' || getURLVar('route') == 'checkout/checkout') {

    }

我认为你需要在“删除”部分修改你的代码：改变如下：

 setTimeout(function () {
                    $('#cart > button').html('<i class="fa fa-shopping-basket"></i>Cart<span id="cart-total">' + total + '</span>');
                }, 100);

到下面：

setTimeout(function () {
                    $('#cart > button').html('<span id="cart-total"><i class="fa fa-shopping-cart"></i> ' + json['total'] + '</span>');
                }, 100);

添加到购物车和删除计数的产品丢失，同时删除opencart中的项目
