getBaseURL（）javascript调用函数在href =“quot;" [英] getBaseURL() javascript call function in a href=""

问题描述

我在html页面中通过javascript调用基础url，我想添加基础url来调用链接

例如。

< a href =getBaseURL（）/ filepath / index.html>页面< / a>


javascript如下：

  function getBaseURL（）{
 var url = location.href; //包含querystring的整个网址 - 另外：window.location.href; 
 var baseURL = url.substring（0，url.indexOf（'/'，14））; （baseURL.indexOf（'http：// localhost'）！= -1）{
 //本地主机的基本URL 
 var url = location.href; 
 
 if // window.location.href; 
 var pathname = location.pathname; // window.location.pathname; 
 var index1 = url.indexOf（pathname）; 
 var index2 = url.indexOf（/，index1 + 1）; 
 var baseLocalUrl = url.substr（0，index2）; 
 
返回baseLocalUrl +/; 
} 
 else {
 //根域Url为域名
返回baseURL +/; 
} 
 
} 
  

编辑

它只是从有问题的域中获取任何基本网址。另外，我从教程中获得了这段代码，所以任何需要较少处理的建议都会非常好，谢谢。

大家好，感谢您的回答，但是，我正在寻找调用html标签的函数，如< a href =getURL（）/ filepath / file.html>< / a> 。这就是问题出在哪里，我不确定如何做到这一点

解决方法

  function getBaseURL（）{
 return location.protocol +//+ location.hostname + 
（location.port& &：+ location.port）+/; 
} 
  

编辑：解决了Mike Samuel在非标准端口上的观点。

I am calling the based url through javascript in a html page and I want to add the base url to call a link

eg.

<a href="getBaseURL()/filepath/index.html">Page</a>

The javascript is as follows:

function getBaseURL() {
    var url = location.href;  // entire url including querystring - also: window.location.href;
    var baseURL = url.substring(0, url.indexOf('/', 14));

    if (baseURL.indexOf('http://localhost') != -1) {
        // Base Url for localhost
        var url = location.href;  // window.location.href;
        var pathname = location.pathname;  // window.location.pathname;
        var index1 = url.indexOf(pathname);
        var index2 = url.indexOf("/", index1 + 1);
        var baseLocalUrl = url.substr(0, index2);

        return baseLocalUrl + "/";
    }
    else {
        // Root Url for domain name
        return baseURL + "/";
    }

}

EDIT

Its just to get any base URL from the domain in question. Also, I got this code from a tutorial so any suggestions that will require less processing would be great thanks

SECOND EDIT

Hi All thanks for your answers so far, however, I am looking to call the function to the html tag as in <a href="getURL()/filepath/file.html></a>. This is where the problem lies, I am unsure how to do that

解决方案

function getBaseURL () {
   return location.protocol + "//" + location.hostname + 
      (location.port && ":" + location.port) + "/";
}

Edit: Addressed Mike Samuel's point on nonstandard ports.
