How to Encode JavaScript Objects for GET Requests?

Encoding JavaScript Objects for GET Requests

In web development, it's often necessary to pass data from a JavaScript application to a server using a GET request. However, JavaScript objects cannot be directly included in URLs. They must be encoded into a string.

Solution:

One straightforward method to encode JavaScript objects for GET requests is to use the following helper function:

serialize = function(obj) {
  var str = [];
  for (var p in obj)
    if (obj.hasOwnProperty(p)) {
      str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
    }
  return str.join("&");
}

Example Usage:

To use this function, simply pass an object as an argument and it will return an encoded string. For instance:

console.log(serialize({
  foo: "hi there",
  bar: "100%"
}));
// Output: foo=hi%20there&bar=100%

Result:

This function encodes the object's properties (key-value pairs) into a string suitable for inclusion in a URL query string. Each property is encoded using encodeURIComponent() for proper formatting.
