The forEach() method of the URLSearchParams interface allows iteration through all values contained in this object via a callback function.

Note: This feature is available in Web Workers.

Syntax

Parameters

callback: A callback function that is executed against each parameter, with the param value provided as its parameter.

Return value

Examples

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

// Log the values
searchParams.forEach(function(value, key) {
  console.log(value, key);
});

The result is:
