This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The URLSearchParams.keys() method returns an iterator allowing to go through all keys contained in this object. The keys are USVString objects.

Note: This method is available in Web Workers.

Syntax

searchParams.keys();

Return value

Returns an iterator.

Example

// Create a test URLSearchParams object 
var searchParams = new URLSearchParams("key1=value1&key2=value2"); 

// Display the key/value pairs 
for(var key of searchParams.keys()) { 
  console.log(key); 
}

The result is:

key1
key2
