How to extract the root website URL using JavaScript for redirection purposes

I am facing an issue with redirecting to the Login page from every page on my website after session timeout. I attempted to set the window location to the login page using the following code:

var ParentUrl = encodeURIComponent(window.parent.location.href);
document.location.href = "/Login.aspx?ReturnUrl=" + ParentUrl;

However, I found that the use of "~" is not supported in this context. My Login page is located under the root folder of my website.

For example: *http://server/website/*Login.aspx

Is there a way to retrieve this URL using JavaScript?

Thank you,

Inbal.

javascript asp.net window.location

Answer №1

If you want to retrieve the parent URL and then encode it, you can simply use window.location.origin. Once you have the parent URL encoded, you can easily append it to a login URL for redirection purposes.

var parentUrl = encodeURIComponent(window.location.href),
    loginUrl = window.location.origin + "/login.html?redirect=" + parentUrl;

window.location.href = loginUrl;

For consistent functionality across different browsers, it's advisable to utilize window.location as it is both readable and writable on all compliant browsers. On the other hand, document.location may be read-only on certain browsers like Internet Explorer.

function retrieveURL() { 
    var parts = window.location.href.split("/"); 
    delete parts[parts.length - 1]; 
    return parts.join("/"); 
}

This method can be implemented as follows:

document.location.href = retrieveURL() + "Login.appx?ReturnUrl=";

The distinction between my function and the initial response is that while a "/" will lead to server/page redirection, my code directs (in your provided URL example) to server/website/page.

Why do we need to use the tilde (~) symbol? Upon closer examination, it appears that removing it may resolve the issue. Consider the following revised code snippet:

document.location.href = "/Login.appx?ReturnUrl=" + ParentUrl;

[UPDATE] In response to the initial comment...

I propose a slight modification to the code that may resolve the issue:

function getLoginPage() {
    var urlParts = document.location.href.split("/");
    return "/" + urlParts[2] + "/" + urlParts[3] + "/Login.aspx";
}

document.location.href = getLoginPage() + "?ReturnUrl=" + ParentUrl;

It is important to note that the section "/website" contains server-side information that cannot be determined solely by JavaScript.

Therefore, it is necessary to transmit this information from the server to the client. One efficient way to achieve this is by passing the complete URL "http://server/website" in one go.

I adjusted the solution provided by PerKristian to suit my specific needs,

function fetchBaseUrl() {
    var regex = new RegExp(/^.*\/\/[^\/]+/);
    return regex.exec(window.location.href);
}

It captures everything until the first single /

My usual practice is to create a file named "settings.js" where I keep all the settings for my application. For instance:

settings = { "root": "myAppRoot/" /*, ... */ };

Then, in my script, I can make a call like this:

myDynamicDiv.load("/" + settings.root + "urlPart1/urlPart2/app"
