如何在网站中进行深层链接

问题描述

<a class="grey-text text-lighten-3" target="_blank" href="javascript:void(0);" onclick="document.write(yourOS())">Instagram</a>



function yourOS() {
var ua = navigator.platform.toLowerCase();
if (ua.indexOf("android") != -1) {
    document.write(.link("instagram://user?username=owendunnigan"));
} else {
    .link("http://www.instagram.com/OwenDunnigan");
}
}

我正在尝试将应用程序深层链接到我的网站，但我不知道如何将其转到计算机上的常规旧Instagram，然后转到Android或iOS设备上的应用程序。我知道链接有效，因为我分别尝试了它们。

I am trying to deep link apps into my website, but I can't figure out how to have it go to regular old Instagram on the computer, but then go to the app on Android or iOS device. I know that the links work because I tried them out individually.

推荐答案

我将以不同的方式来处理。而不是onclick检查源，我将执行此onload。因此：

I would approach this in a different manner. Instead of onclick checking the source, I would do this onload. So:

    <script>
    function onLoad(){
       var urlLink = "http://www.instagram.com/OwenDunnigan";
       var urlLink2 = "http://www.twitter.com/OwenDunnigan";
       var urlLink3 = "http://www.facebook.com/OwenDunnigan";
       var ua = navigator.userAgent.toLowerCase();
       var isAndroid = ua.indexOf("android") > -1;
       if(isAndroid) {
          urlLink = "instagram://user?username=owendunnigan";
          urlLink = "twitter://user?username=owendunnigan";
          urlLink = "facebook://user?username=owendunnigan";
       }
       document.getElementById('yourLink').setAttribute('href', urlLink);
       document.getElementById('yourLink2').setAttribute('href', urlLink2);
       document.getElementById('yourLink3').setAttribute('href', urlLink3);
    }
    window.onload = onLoad;
    </script>

    <a id="yourLink" class="grey-text text-lighten-3" target="_blank">Link</a>

我在我的android设备/笔记本电脑上对此进行了测试，并且对两者均有效。

I tested this on my android device / laptop and it worked for both.

编辑：肮脏的方式。您可以通过具有onload函数的函数来调用传递变量来制作更具有OOP风格的样式，但是为了简单起见，这可以解决问题。

Down and dirty way. You could make a more OOP style by having a function for the onload function to call passing in the variables, but for simplicity, this does the trick.

Edit2：

<script>
        function getMobileOperatingSystem() {
           var userAgent = navigator.userAgent || navigator.vendor || window.opera;
           if( userAgent.match( /iPad/i ) || userAgent.match( /iPhone/i ) || userAgent.match( /iPod/i ) )
           {
              return 'iOS';
           }
           else if( userAgent.match( /Android/i ) )
           {
              return 'Android';
           }
           else
           {
              return 'unknown';
           }
        }

        function onLoad(){
           var urlLink1 = "http://www.instagram.com/OwenDunnigan";
           var urlLink2 = "http://www.twitter.com/OwenDunnigan";
           var urlLink3 = "http://www.facebook.com/OwenDunnigan";
           switch(getMobileOperatingSystem()){
               case 'Android':
                    urlLink1 = "instagram://user?username=owendunnigan";
                    urlLink2 = "twitter://user?username=owendunnigan";
                    urlLink3 = "facebook://user?username=owendunnigan";
                    break;
               case 'iOS':
                    urlLink1 = "instagram://user?username=owendunnigan";
                    urlLink2 = "twitter://user?username=owendunnigan";
                    urlLink3 = "facebook://user?username=owendunnigan";
                    break;
               default:
                    break;
            }
           document.getElementById('yourLink1').setAttribute('href', urlLink1);
           document.getElementById('yourLink2').setAttribute('href', urlLink2);
           document.getElementById('yourLink3').setAttribute('href', urlLink3);
        }
        window.onload = onLoad;
        </script>

        <a id="yourLink1" class="grey-text text-lighten-3" target="_blank">Link1</a>
        <a id="yourLink2" class="grey-text text-lighten-3" target="_blank">Link2</a>
        <a id="yourLink3" class="grey-text text-lighten-3" target="_blank">Link3</a>

清理代码并从此处滚动功能：
您可以通过简单地扩展detect函数并添加case语句来添加其他系统。当然，我没有添加通常情况下的默认case语句，但是我首先调用了变量，因此我认为没有理由重置它们，但是您可以做很多事情。让我知道这是否行不通。

Cleaned up the code and rolled in the function from here: Detecting iOS / Android Operating systemYou can add other systems by simply expanding the detect function and adding case statements. Granted, I didn't add a default case statement which you normally do, but I invoked the variables first, so no reason to reset them in my opinion, but you could do a lot more with it. Let me know if this doesn't work.
