如何创建多维数组/对象在jquery和传递通过AJAX post [英] how to create multidimensional array / object in jquery and pass via AJAX post
问题描述
我创建了一个订单表单,其中包含用户可以购买的订单项目表。输入使用数据属性来存储项目名称和每件的价格,如:
I am creating an order form that has a table of order items users can purchase. The inputs are using data attributes to store the items name and price per piece like so:
<input type="text" class="input-small quantity-input" data-pid="<?php echo $p['id']; ?>" data-min="<?php echo $p['min_qty']; ?>" data-max="<?php echo $p['max_qty']; ?>" data-price="<?php echo $p['price']; ?>" data-name="<?php echo $p['product_name']; ?>" placeholder="quantity...">
除了如何遍历每个数量输入项目并将其添加到多维数组,我可以通过AJAX发送。我目前有以下代码,但是当我对$ _POST值做一个print_r它说:禁止的关键字符:新鲜的罗非鱼文件
I have everything figured out except for how to iterate over each quantity-input item and add it to a multidimensional array that I can send via an AJAX Post. I currently have the following code, but when I do a print_r on the $_POST value it says: Disallowed Key Characters: Fresh Tilapia Filets
$("#ccform").validate({
rules: {
firstName: { required: true },
lastName: { required: true },
email: {
required: true,
email: true,
},
cardNumber: { required: true },
expMonth: { required: true },
expYear: { required: true },
cvv: { required: true },
address: { required: true },
city: { required: true },
state: { required: true },
zipcode: { required: true },
phone: { required: true },
},
submitHandler: function() {
var siteUrl = $('#siteUrl').val();
var orderItems = [];
$('.quantity-input').each(function(){
var orderItem = $(this).attr('data-name');
var priceEach = $(this).attr('data-price');
var qty = $(this).val();
if(qty != '') {
obj = {};
obj[orderItem] = orderItem;
obj[priceEach] = priceEach;
obj[qty] = qty;
orderItems.push(obj);
}
});
var pickupLocation = $('input[name="pickup"]:checked').val();
var pickupPrice = $('#hidePickupPrice').val();
var subtotal = $('#hideSubtotal').val();
var tax = $('#hideTax').val();
var total = $('#hideTotal').val();
var firstName = $('#firstName').val();
var lastName = $('#lastName').val();
var email = $('#email').val();
var cardNumber = $('#cardNumber').val();
var expMonth = $('#expMonth').val();
var expYear = $('#expYear').val();
var cvv = $('#cvv').val();
var address = $('#address').val();
var address2 = $('#address2').val();
var city = $('#city').val();
var state = $('#state').val();
var zipcode = $('#zipcode').val();
var phone = $('#phone').val();
$.ajax({
type: "POST",
url: siteUrl + "frontend/pay",
data: ({ 'orderItems': orderItems, 'pickupLocation': pickupLocation, 'pickupPrice': pickupPrice, 'subtotal': subtotal, 'tax': tax, 'total': total, 'firstName': firstName, 'lastName': lastName, 'email': email, 'cardNumber': cardNumber, 'expMonth': expMonth, 'expYear': expYear, 'cvv': cvv, 'address': address, 'address2': address2, 'city': city, 'state': state, 'zipcode': zipcode, 'phone': phone}),
success: function(data) {
alert('done!');
}
});
},
});
我通常不会进入Jquery这么多,所以它可能只是一个noob问题,格式化jquery对象。此外,我使用Codeigniter的PHP框架。 您可以在这里查看直播版本

到澄清,这是我需要帮助的代码的区域。它不是创建多维对象/数组:
To clarify, this is the area of the code I need help with. It is not creating a multi dimensional object / array:
var orderItems = [];
$('.quantity-input').each(function(){
var orderItem = $(this).attr('data-name');
var priceEach = $(this).attr('data-price');
var qty = $(this).val();
if(qty != '') {
obj = {};
obj[orderItem] = orderItem;
obj[priceEach] = priceEach;
obj[qty] = qty;
orderItems.push(obj);
}
});
推荐答案
您需要引用您的密钥:
obj['orderItem'] = orderItem;
obj['priceEach'] = priceEach;
obj['qty'] = qty;
或使用点符号:
obj.orderItem = orderItem;
obj.priceEach = priceEach;
obj.qty = qty;
没有引号或圆点符号的说法:
Without the quotes/dot notation its like saying:
obj['Fresh Tilapia Filets'] = 'Fresh Tilapia Filets';
obj['$2.99'] = '$2.99';
obj[10] = 10;
因为它使用相同的名称评估变量。
Because its evaluating the variables with the same name.
