HTML 电子邮件按钮

Question

这里非常新，所以我确信我错过了一些明显的东西，但我想要一个 HTML 按钮，用于打开用户本机电子邮件客户端，并预先填充“收件人：”字段。

<form>
  <button class="button-21"  action="mailto:[email protected]" type="submit"> Contact</button>
</form> 

这是随附的 CSS：

.button-21 {
  align-items: center;
  appearance: none;
  background-color: #3eb2fd;
  background-image: linear-gradient(1deg, #4f58fd, #149bf3 99%);
  background-size: calc(100% + 20px) calc(100% + 20px);
  border-radius: 100px;
  border-width: 0;
  box-shadow: none;
  box-sizing: border-box;
  color: #ffffff;
  cursor: pointer;
  display: inline-flex;
  font-family: CircularStd, sans-serif;
  font-size: 1rem;
  height: auto;
  justify-content: center;
  line-height: 1.5;
  padding: 6px 20px;
  position: relative;
  text-align: center;
  text-decoration: none;
  transition: background-color 0.2s, background-position 0.2s;
  user-select: none;
  -webkit-user-select: none;
  touch-action: manipulation;
  vertical-align: top;
  white-space: nowrap;
}

.button-21:active,
.button-21:focus {
  outline: none;
}

.button-21:hover {
  background-position: -20px -20px;
}

.button-21:focus:not(:active) {
  box-shadow: rgba(40, 170, 255, 0.25) 0 0 0 0.125em;

Answer 1

action 是表单的提交属性。您应该将操作属性从按钮移至表单。

.button-21 {
  align-items: center;
  appearance: none;
  background-color: #3eb2fd;
  background-image: linear-gradient(1deg, #4f58fd, #149bf3 99%);
  background-size: calc(100% + 20px) calc(100% + 20px);
  border-radius: 100px;
  border-width: 0;
  box-shadow: none;
  box-sizing: border-box;
  color: #ffffff;
  cursor: pointer;
  display: inline-flex;
  font-family: CircularStd, sans-serif;
  font-size: 1rem;
  height: auto;
  justify-content: center;
  line-height: 1.5;
  padding: 6px 20px;
  position: relative;
  text-align: center;
  text-decoration: none;
  transition: background-color 0.2s, background-position 0.2s;
  user-select: none;
  -webkit-user-select: none;
  touch-action: manipulation;
  vertical-align: top;
  white-space: nowrap;
}

.button-21:active,
.button-21:focus {
  outline: none;
}

.button-21:hover {
  background-position: -20px -20px;
}

.button-21:focus:not(:active) {
  box-shadow: rgba(40, 170, 255, 0.25) 0 0 0 0.125em;
}

<form action="mailto:[email protected]">
  <button class="button-21" type="submit">Contact</button>
</form>
