How can I use URL parameters in my web application?
You can use URL parameters to pass data to your web application. They are added to the URL after a question mark, like this: ?key=value
.
Can you give me an example of how to retrieve these parameters in JavaScript?
Sure! You can use URLSearchParams
in JavaScript. For example:
const params = new URLSearchParams(window.location.search);
const value = params.get('key');
What if I have multiple parameters?
You can simply separate them with an ampersand. For example: ?key1=value1&key2=value2
. You can retrieve them the same way using URLSearchParams
.
Are there any limitations to using URL parameters?
Yes, URL parameters have a size limit (usually around 2000 characters) and should not contain sensitive information.
