How to change data sent via ajax?

Question

JavaScript

Below in the function there is such a thing json['total'] - it stores

{success: "Shopping cart updated!", total: "Items: 0 ($0)"}
success: "Shopping cart updated!"
total: "Items: 0 ($0)"

How can I change json['total'] to store something like this

{success: "Shopping cart updated!", total: "Items: 0 ($0)"}
success: "Shopping cart updated!"
total: "Items: 0 "
price: "$0"

'remove': function(key) {
    $.ajax({
      url: 'index.php?route=checkout/cart/remove',
      type: 'post',
      data: 'key=' + key,
      dataType: 'json',		
      success: function(json) {
        $('#cart > button').html('<svg class="icon icon-cart">'+ json['total']);

        if (getURLVar('route') == 'checkout/cart' || getURLVar('route') == 'checkout/checkout') {
          location = 'index.php?route=checkout/cart';
        } else {
          $('#cart > ul').load('index.php?route=common/cart/info ul li');
        }
      }
    });
  }

There is a controller

<?php 
<?php 
class ControllerExtensionModulePopupCart extends Controller {

  public function index() {
    $this->load->language('common/cart');
    $this->language->load('extension/module/popupcart');

    $data['text_price'] = $this->language->get('text_price');
    $data['text_total'] = $this->language->get('text_total');
    
    
    
    if (file_exists('catalog/view/theme/'.$this->config->get($this->config->get('config_theme') . '_directory').'/stylesheet/popupcart.css')) {
      $this->document->addStyle('catalog/view/theme/'.$this->config->get($this->config->get('config_theme') . '_directory').'/stylesheet/popupcart.css?ver=1.6.1');

Answer 1

var test = {success: "Корзина покупок обновлена!", total: "Товаров: 0 (0 руб.)"};
test.price = test.total.replace(/.*\((.*)\)/, '$1');
test.total = test.total.replace(/\(.*\)/, '');
console.log(test);

//[object Object] {
//  price: "0 руб.",
//  success: "Корзина покупок обновлена!",
//  total: "Товаров: 0 "
}
