I'm trying to avoid the "Cannot open page. Safari cannot open the page because the address is invalid." 我试图避免“无法打开页面.Safari无法打开页面,因为地址无效。” type messages on things like iPod/iPad etc.
输入iPod / iPad等信息。
Thanks. 谢谢。
On desktop Skype uses the "callto:" spec instead of "tel:" 在桌面上Skype使用“callto:”规范而不是“tel:”
I think you could use css for this. 我想你可以用css来做这件事。
Just add some @media rules: 只需添加一些@media规则:
.telClass { display: none; }
.callToClass { display: block; }
@media only screen and (max-device-width: 480px) {
.tel-class { display: block; }
.call-to-class { display: none; }
}
Then you could define two elements in html: 然后你可以在html中定义两个元素:
<a href="tel:555555555" class="tel-class">Call us on 555555555</a>
<a href="callto:555555555" class="call-to-class">Call us on 555555555</a>
For a more complex code you could add some javascript code to check if the device is a handheld one: 对于更复杂的代码,您可以添加一些JavaScript代码来检查设备是否为手持设备:
if( /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent) ) {
var callToArray = document.getElementsByClassName('call-to-class');
callToArray.forEach(function(c) {
c.parentElement.removeChild(c);
});
}
