由于转换函数，AJAX JSON解析错误？

Question

我有一个函数，在单击按钮后，遍历每个选定元素，通过$ .ajax检索数据，然后将json数据写入新窗口。

当我只选择一个元素时，它的效果非常好。但是，如果我选择多个，我会在JSON数据的第1行第1列收到＆＃34; SyntaxError：JSON.parse：意外字符＆＃34;。

编辑:: 我在.tpl文件中找到了一个函数，当省略时，页面加载时没有解析错误。我使用此函数将字符串转换为货币。如何重写此功能以便我仍然可以使用它？它在像array_walk这样的地方调用（$ product_total，＆＃34; convertCurrencyStringtoNumber＆＃34;）;

function convertCurrencyStringtoNumber(&$item, $key) {
    $currency = 'USD';
    $formatter = new NumberFormatter('en_US', NumberFormatter::CURRENCY);
    $item = $formatter->parseCurrency($item, $currency);
}

AJAX功能：

$('#print_depositreport').on('click', function() {
    var order_ids = [];
    $('.selected').each(function() {
        if ($(this).attr('checked')) {
            order_ids.push($(this).attr('title'));
        }
    });
    var new_window = window.open();
    $.ajax({
        url: 'index.php?route=sale/order_entry/depositreport&token=<?php echo $token; ?>',
        type: 'GET',
        dataType: 'json',
        data: 'order_id=' + order_ids + '&type=print',
        success: function(json) {
            new_window.document.write(json);
            new_window.document.close();
            new_window.focus();
            new_window.document.write(htmlPage);
            new_window.close();
        },
        error: function(xhr,j,i) {
            alert(i);
        }
    });
});
