我创建了一个电话号码认证系统。用户输入他们的电话号码，并向电话发送代码，用户在网站上输入该代码，以及这些代码的验证方式。我想捕获他们在网站上输入的号码。我在div下创建了一个cookie “电话”来捕捉电话号码。我想在谷歌地图上使用标记显示所有用户的位置，我希望谷歌地图标记显示分配给该用户的个人电话号码，因此在我的其他文件中，我创建了一个具有cookie值的变量。然后我制作了变量的标记标签，我认为电话号码会出现，但标记标签没有显示。我不知道该怎么办，如果有人能帮我这个，我会非常感激。{{3 }}

Answer 1

查看代码后，我意识到您应该使用document.cookie = document.getElementById("phone").innerHTML;来使用document.cookie = "PhoneNumber="+document.getElementById("phone").value;来获取输入值。因此，解决问题所需要做的就是将.innerHTML更改为.value并为Cookie声明一个名称，否则它将无法保存为Cookie。

使用.innerHTML将获取元素中的所有HTML，而.value将获取用户键入/选择的内容。

希望这有助于解决您的问题。

为div创建cookie
