自定义HTML标签：JS编译错误为userType dataLayer推

Question

我一直在尝试适应现有的（&工作标签），如果你愿意更高效/优雅一点。

所以情况是，我们有一种通过GTM自定义HTML标签将userType推入dataLayer的方法。不过，我试图发布标签时遇到了编译错误。

这里的标签：

<script> 
(function() { 
var ipaddress;; 
var type = 'external'; 
try { 
    jQuery.getJSON('https://ipinfo.io', function(data) { 
    ipaddress = data.ip; 
    var internal = [ 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address" 
    ]; 
    var userType = internal.indexOf(ipaddress) == -1 ? ‘external’ : ‘internal’; 
    } 
    if (ipaddress) { 
     window.dataLayer.push({ 
     event: 'ipResolved', 
     ipaddress: ipaddress, 
     userType: userType 
     }); 
    } 
    }); 
} catch(e) { 
    window.dataLayer.push({ 
    event: 'ipResolved', 
    ipaddress: 'N/A', 
    iplocation: 'N/A' 
    }); 
} 
})(); 
</script> 

任何人都可以揭示我要去哪里错了一些轻？我觉得我太靠近了，所以我看不到明显的。

你的JS有一些小错误：

• 错误报价。这是‘代替'
• 一个不必要}

。工作版本在这里：

(function() { 
var ipaddress; 
var type = 'external'; 
try { 
    jQuery.getJSON('https://ipinfo.io', function(data) { 
    ipaddress = data.ip; 
    var internal = [ 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address", 
     "IP address" 
    ]; 
    var userType = internal.indexOf(ipaddress) == -1 ? 'external' : 'internal'; 

    if (ipaddress) { 
     window.dataLayer.push({ 
     event: 'ipResolved', 
     ipaddress: ipaddress, 
     userType: userType 
     }); 
    } 
    }); 
} catch(e) { 
    window.dataLayer.push({ 
    event: 'ipResolved', 
    ipaddress: 'N/A', 
    iplocation: 'N/A' 
    }); 
} 
})();
