如何用innerHTML替換document.write

我想用document.write替換innerHTML。但是當我嘗試時它不會創建鏈接。我不知道我是如何構建路徑變量的問題，因此它不會將鏈接正確打印出來。現在它不會打印出任何鏈接。如何用innerHTML替換document.write

<!DOCTYPE html> 
<html lang="en"> 

<script> 

    var path = ""; 
    var href = document.location.href; 
    var s = href.split("/"); 
    for (var i=2;i<(s.length-1);i++) { 
     path+="<a class='crumb' href=\""+href.substring(0,href.indexOf("/"+s[i])+s[i].length+1)+"/\">"+s[i]+" </a>"; 
    } 
    i=s.length-1; 
    path+="<a class='crumb' href=\""+href.substring(0,href.indexOf(s[i])+s[i].length)+"\">"+s[i]+" </a>"; 
    var url = path; 
    //document.getElementById(".breadcrumb").innerHTML = url; 
    document.write(url); 

</script>

請編輯您的問題，以便爲包括[最小，完整，可驗證的示例]（http://stackoverflow.com/help/mcve ）。 – MJH

這不能工作'document.getElementById（'。breadcrumb'）' – antoni

你的腳本標籤位於html中？顯示html –

<div id ="breadcrumb"> </div> <script> var path = ""; var href = document.location.href; var s = href.split("/"); for (var i=2;i<(s.length-1);i++) { path+="<a class='crumb' href=\""+href.substring(0,href.indexOf("/"+s[i])+s[i].length+1)+"/\">"+s[i]+" </a>"; } i=s.length-1; path+="<a class='crumb' href=\""+href.substring(0,href.indexOf(s[i])+s[i].length)+"\">"+s[i]+" </a>"; var url = path; document.getElementById('breadcrumb').innerHTML = url; //document.write(url); </script>
