我有類似JavaScript來提取的兄弟姐妹,然後將數據發送到Django的
<tbody id="order_table">
<tr class="list">
<td data-status="old" class="food_name">food1</td>
<td class="quantity">1</td>
<td class="price">$10.00</td>
<td><button type="button" class="btnIncrement btn"> <span class="fa fa-plus"></span></button></td>
</tr>
<tr class="list">
<td data-status="old" class="food_name">food111</td>
<td class="quantity">1</td>
<td class="price">$10.00</td>
<td><button type="button" class="btnIncrement btn"> <span class="fa fa-plus"></span></button></td>
</tr>
<tr class="list">
<td data-status="new" class="food_name">food11</td>
<td class="quantity">1</td>
<td class="price">$10.00</td>
<td><button type="button" class="btnIncrement btn"> <span class="fa fa-plus"></span></button></td>
</tr>
<tr class="list">
<td data-status="new" class="food_name">food12</td>
<td class="quantity">1</td>
<td class="price">$10.00</td>
<td><button type="button" class="btnIncrement btn"> <span class="fa fa-plus"></span></button></td>
</tr>
</tbody>
我想提取每個new
項的食品名稱,數量及價格,並付諸陣列,最後發送到Django的由ajax .. 訂單並不重要 這就是我想要的。
[[food11, 1, 10.00], [food12, 1, 10.00]]
如果沒有新的項目存在,就會返回
[]
我真的不能看着辦吧。所以我想一些幫助。非常感謝你
