自定义表单提交按钮

Question

我正在为MailChimp列表创建自定义订阅按钮。我似乎无法将按钮与表单输入法链接起来。

var subscribe_button = document.querySelector(".fi-mail");

subscribe_button.addEventListener('click', function(){
	subscribe_button.classList.remove("fi-mail");
  subscribe_button.classList.add("fi-check");
});

Answer 1

看看这个答案，因为我认为这很好地回答了您的问题：（Is it safe to use anchor to submit form?）。

简短答案：以下任何一种方法都可以代替锚标签。

try(/*initialize resources here*/) { }

或

<input type="submit" value="Submit!" />
