JavaScript DOM 没有响应
[英]JavaScript DOM doesn't respond
问题描述
我正在尝试制作迷你交付项目。 这是计算运费的页面。 它会计算保险价格和运费，但不会在“总计”部分中汇总。 在输出中，它写下NaN$ ，仅此而已。 我尝试了我所知道的，也使用了互联网但无法解决这个错误。 这里有什么错误？ 为什么不总结呢？ （不要介意设计）

total.innerHTML=parseInt(insurance)+parseInt(transportation);
这条线是问题所在。 保险和运输是 DOM 元素，而不是字符串。 您可能打算在他们的 innerHTML 上调用 parseInt
total.innerHTML=parseInt(insurance.innerHTML)+parseInt(transportation.innerHTML);
