如何使移动用户可点击动态电话号码

How to make dynamic phone number clickable for mobile users

本文关键字：动态 电话号码 何使 移动 用户      更新时间：2023-09-26

我的网站上有通过 JavaScript 自动插入的电话号码，以显示默认电话号码（在主 JavaScript 中定义），或者如果网页通过包含电话号码的 URL 字符串访问，则更改为可变电话号码 - 例如： 

http:www.website.com?tfid=8005551212

我需要做的是使移动用户可单击电话号码，以便无论出现哪个电话号码，他们都可以单击它，它将呼叫电话号码。

我知道，如果您用带有 tel： 属性的锚点包装电话号码，它将启动点击呼叫功能，但是如何编写标签以允许传递电话号码变量？ 例如： 

可变电话号码">可变电话号码

你是这个意思吗？请重写您的脚本以不使用 document.write。如果您在页面加载后调用其中一个函数，它将擦除页面。

document.getElementById("phonenumber").innerHTML='<a href="tel:'+phone_number+'">'+phone_number+'</a>';

像这样，使用您的原始代码

<div id="phonenumber">Call:  </div>

function getPhone() {
   var phone = get_named_cookie("MM_TrackableNumber");
   if (phone == null) phone = "8885551313";
   return formatnumber(phone);
}
window.onload=function() {
  document.getElementById("phonenumber").innerHTML+=getPhone();
}

   function pixelfire(debug) {
       var phone_number = getVar("phone_number");
       var keyword = getVar("keyword");
