When working on web development projects, you might encounter the need to manipulate URLs in JavaScript. One common task is to remove the domain from the location.href value. This can be useful for various reasons, such as constructing relative URLs or extracting specific parts of the URL for further processing.
To remove the domain from the location.href in JavaScript, you can follow a simple process using string manipulation techniques. The location.href property in JavaScript contains the complete URL of the current page, including the protocol, domain, path, and query parameters. If you only want to extract the path and query parameters without the domain, you can use the following steps.
First, you need to access the location.href property, which is a string representing the complete URL of the current page. You can do this by simply referencing the location.href property in your JavaScript code.
const currentURL = window.location.href;Once you have the complete URL stored in a variable, you can proceed to remove the domain part. Since the domain is usually followed by the first forward slash ('/'), you can use the indexOf() method to find the position of the first '/' character after the protocol specifier '://'.
const domainIndex = currentURL.indexOf('://') + 3;
const pathAndQuery = currentURL.substring(currentURL.indexOf('/', domainIndex));In the code snippet above, we first determine the index of the first character after the '://' protocol specifier. By adding 3 to this index, we skip past the domain part and start extracting the path and query parameters using the substring() method.
Finally, the 'pathAndQuery' variable will contain the path and query parameters extracted from the complete URL without the domain part. You can now use this value in your JavaScript code for further processing or manipulation.
console.log(pathAndQuery);By logging the 'pathAndQuery' variable to the console, you can verify that the domain has been successfully removed from the location.href value, leaving only the path and query parameters.
In summary, removing the domain from the location.href in JavaScript involves accessing the complete URL, finding the position of the domain part, and extracting the path and query parameters using string manipulation methods. This can be helpful when you need to work with relative URLs or extract specific parts of the URL for further processing in your web development projects.
I hope this how-to guide has been informative and useful for your JavaScript programming needs. Feel free to explore more string manipulation techniques and experiment with different approaches to achieve your desired outcomes. Happy coding!
