javascript - 从 jquery 插件打印选定的选项

标签 javascript jquery css jsp plugins

我正在尝试在我的 jsp 网站上使用 Jquery 电影座位选择插件。该插件运行良好，我可以选择座位。

我的问题是，因为我不知道 Jquery，所以我无法在我的 jsp 页面上打印用户选择的座位。

请帮我在jsp页面上打印用户选择的座位。这样我就可以使用它们存储在我的 derby 数据库中。

HTML

  <div class="demo">
    <div id="seat-map">
        <div class="front">SCREEN</div>                
    </div>

    <div class="booking-details">


        <p>Seat: </p>
        <ul id="selected-seats"></ul>
        <p>Tickets: <span id="counter">0</span></p>
        <p>Total: <b>Rs.<span id="total">0</span></b></p>

                    <a href="ticketValidation"><input type="button" value="BUY" class="checkout-button"/></a>

        <div id="legend"></div>
    </div>
    <div style="clear:both"></div>

J查询:

最佳答案

我可能会建议您使用 jQuery 对话框插件 ( dialog )，加上 jsPDF为了在打印按钮上生成一个对话框，其中包含与您选择的座位相关的 html 的 pdf 版本。

结果是这样的: enter image description here

片段是:

var price = 120; //price
var sc;

//sum total money
function recalculateTotal(sc) {
  var total = 0;
  sc.find('selected').each(function () {
    total += price;
  });

  return total;
}

$(function () {
  var $cart = $('#selected-seats'), //Sitting Area

      $counter = $('#counter'), //Votes
      $total = $('#total'); //Total money

  sc = $('#seat-map').seatCharts({
    map: [  //Seating chart
      'aaaaaaaaaa',
      'aaaaaaaaaa',
      'aaaaaaaaaa',
      'aaaaaaaaaa',
      'aaaaaaaaaa',
      'aaaaaaaaaa',
      'aaaaaaaaaa',
      'aaaaaaaaaa',
      'aaaaaaaaaa',

    ],
      naming: {
      top: false,
      getLabel: function (character, row, column) {
      return column;
      }
      },
      legend: { //Definition legend
      node: $('#legend'),
      items: [
      ['a', 'available', 'Avail'],
    ['a', 'unavailable', 'Sold']
    ]
  },
                                 click: function () { //Click event
    if (this.status() == 'available') { //optional seat
      $('<li>R' + (this.settings.row + 1) + ' S' + this.settings.label + '</li>')
      .attr('id', 'cart-item-' + this.settings.id)
      .data('seatId', this.settings.id)
      .appendTo($cart);

      $counter.text(sc.find('selected').length + 1);
      $total.text(recalculateTotal(sc) + price);

      return 'selected';
    } else if (this.status() == 'selected') { //Checked
      //Update Number
      $counter.text(sc.find('selected').length - 1);
      //update totalnum
      $total.text(recalculateTotal(sc) - price);

      //Delete reservation
      $('#cart-item-' + this.settings.id).remove();
      //optional
      return 'available';
    } else if (this.status() == 'unavailable') { //sold
      return 'unavailable';
    } else {
      return this.style();
    }
  }
});
//sold seat
sc.get(['1_2', '4_4', '4_5', '6_6', '6_7', '8_5', '8_6', '8_7', '8_8', '10_1', '10_2']).status('unavailable');
