在joomla php中，我可以使用$this->baseurl来获得基本路径，但我想在jquery中获得基本路径。
基本路径可以是以下示例中的任意一个:
http://www.example.com/
http://localhost/example
http://www.example.com/sub/example
例子也可能改变。

获取基本url 从js调用控制器
function getURL() {
var windowurl = window.location.href;
var baseUrl = windowurl.split('://')[1].split('/')[0]; //split function
var xhr = new XMLHttpRequest();
var url='http://'+baseUrl+'/url from controller';
xhr.open("GET", url);
xhr.send(); //object use to send
xhr.onreadystatechange=function() {
if(xhr.readyState==4 && this.status==200){
//console.log(xhr.responseText); //the response of the request
document.getElementById("id from where you called the function").innerHTML = xhr.responseText;
}
}
}
其他回答
var getUrl = window.location;
var baseurl = getUrl.origin; //or
var baseurl = getUrl.origin + '/' +getUrl.pathname.split('/')[1];
但你不能说CodeIgniter(或php joomla)的baseurl()将返回相同的值，因为可以更改这些框架的.htaccess文件中的baseurl。
例如:
如果你在本地主机上有一个。htaccess文件:
RewriteEngine on
RewriteBase /CodeIgniter/
RewriteCond $1 !^(index.php|resources|robots.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]
$this->baseurl()将返回http://localhost/CodeIgniter/
获取基本url 从js调用控制器
function getURL() {
var windowurl = window.location.href;
var baseUrl = windowurl.split('://')[1].split('/')[0]; //split function
var xhr = new XMLHttpRequest();
var url='http://'+baseUrl+'/url from controller';
xhr.open("GET", url);
xhr.send(); //object use to send
xhr.onreadystatechange=function() {
if(xhr.readyState==4 && this.status==200){
//console.log(xhr.responseText); //the response of the request
document.getElementById("id from where you called the function").innerHTML = xhr.responseText;
}
}
}
window.location.origin+"/"+window.location.pathname.split('/')[1]+"/"+page+"/"+page+"_list.jsp"
几乎和Jenish的答案一样，但更短一点。
这将得到base url
var baseurl = window.location.origin+window.location.pathname;
如果有人想把它分解成一个非常健壮的函数
function getBaseURL() {
var loc = window.location;
var baseURL = loc.protocol + "//" + loc.hostname;
if (typeof loc.port !== "undefined" && loc.port !== "") baseURL += ":" + loc.port;
// strip leading /
var pathname = loc.pathname;
if (pathname.length > 0 && pathname.substr(0,1) === "/") pathname = pathname.substr(1, pathname.length - 1);
var pathParts = pathname.split("/");
if (pathParts.length > 0) {
for (var i = 0; i < pathParts.length; i++) {
if (pathParts[i] !== "") baseURL += "/" + pathParts[i];
}
}
return baseURL;
}
