移除HTML5 input在type="number"时的上下小箭头
- 在chrome下：
input::-webkit-outer-spin-button,input::-webkit-inner-spin-button{ -webkit-appearance: none !important; margin: 0; }- Firefox下：
input[type="number"]{ -moz-appearance:textfield;}- 第二种方案：
- 将type="number"改为type="tel"，同样是数字键盘，但是没有箭头。
@media screen and (orientation: portrait) { /*竖屏 css*/ } @media screen and (orientation: landscape) { /*横屏 css*/ } //判断手机横竖屏状态：window.addEventListener("onorientationchange" in window ? "orientationchange" : "resize", function() { if (window.orientation === 180 || window.orientation === 0) { alert('竖屏状态！'); } if (window.orientation === 90 || window.orientation === -90 ){ alert('横屏状态！'); } }, false); //移动端的浏览器一般都支持window.orientation这个参数，通过这个参数可以判断出手机是处在横屏还是竖屏状态。 -
