检查< a href =" tel:5555555">被支持 [英] Check if <a href="tel:5555555"> is supported
问题描述
是否可以检查浏览器是否支持电话号码超链接?
EG:检查
< a href =tel:555555555>拨打我们555555555<一个>
可以使用。
我是试图避免无法打开页面,Safari无法打开页面,因为地址无效。如iPod / iPad等类型的消息。
谢谢。
p>在桌面上,Skype使用callto:规范而不是tel:我认为你可以使用css。
只需添加一些@media规则:
.telClass {display:none; }
.callToClass {display:block; }
@media只有屏幕和(最大设备宽度:480px){
.tel-class {display:block; }
.call-to-class {display:none; }
}
然后你可以在html中定义两个元素:
$ b
< a href =tel:555555555class =tel-class> Call us on 555555555< / a>
< a href =callto:555555555class =call-to-class>致电555555555< / a>
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是手持设备:
$ b $
if(/ Android | webOS | iPhone | iPad | iPod | BlackBerry | IEMobile | Opera Mini / i.test(导航器。 userAgent)){
var callToArray = document.getElementsByClassName('call-to-class');
callToArray.forEach(function(c){
c.parentElement.removeChild(c);
});
}
还有一个很好的答案 ,通过 ghepting 了解如何检测Skype是否已安装或不。
Is it possible to check if a phone number hyperlink is supported by a browser? EG: Check if
<a href="tel:555555555">Call us on 555555555</a>
will work.
I'm trying to avoid the "Cannot open page. Safari cannot open the page because the address is invalid." type messages on things like iPod/iPad etc.
Thanks.
On desktop Skype uses the "callto:" spec instead of "tel:"
I think you could use css for this.
Just add some @media rules:
.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:
<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:
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);
});
}
Also there is a nice answer here by ghepting on how to to detect if skype is installed or not.
