Question

我正在开发自己的第一个自定义shopify网站，但我试图添加功能。

我需要使用文本类型而不是数字类型来实现购物车数量的+/-数字增量（以删除向上箭头，黎明箭头）。

这是HTML输入标签

    <input type="number" id="updates_{{ item.key }}"
    value="{{ item.quantity }}" min="0" pattern="[0-9]*"
    data-quantity-item="{{ forloop.index }}">

Answer 1

input[type="number"] {
  -webkit-appearance: textfield;
  -moz-appearance: textfield;
  appearance: textfield;
}

input[type=number]::-webkit-inner-spin-button,
input[type=number]::-webkit-outer-spin-button {
  -webkit-appearance: none;
}

.number-input {
  border: 2px solid #ddd;
  display: inline-flex;
}

.number-input,
.number-input * {
  box-sizing: border-box;
}

.number-input button {
  outline:none;
  -webkit-appearance: none;
  background-color: transparent;
  border: none;
  align-items: center;
  justify-content: center;
  width: 3rem;
  height: 3rem;
  cursor: pointer;
  margin: 0;
  position: relative;
}

.number-input button:before,
.number-input button:after {
  display: inline-block;
  position: absolute;
  content: '';
  width: 1rem;
  height: 2px;
  background-color: #212121;
  transform: translate(-50%, -50%);
}
.number-input button.plus:after {
  transform: translate(-50%, -50%) rotate(90deg);
}

.number-input input[type=number] {
  font-family: sans-serif;
  max-width: 5rem;
  padding: .5rem;
  border: solid #ddd;
  border-width: 0 2px;
  font-size: 2rem;
  height: 3rem;
  font-weight: bold;
  text-align: center;
}

<div class="number-input">
  <button onclick="this.parentNode.querySelector('input[type=number]').stepDown()" ></button>
  <input class="quantity" min="0" name="quantity" value="1" type="number">
  <button onclick="this.parentNode.querySelector('input[type=number]').stepUp()" class="plus"></button>
</div>

您可以使用CSS执行此操作：

input[type="number"]::-webkit-outer-spin-button, input[type="number"]::-webkit-inner-spin-button {
-webkit-appearance: none;
margin: 0;
}
input[type="number"] {
-moz-appearance: textfield;
}

    <input type="number" id="updates_{{ item.key }}"
    value="{{ item.quantity }}" min="0" pattern="[0-9]*"
    data-quantity-item="{{ forloop.index }}">
