History.state

The History.state property returns an any value representing the state at the top of the history stack. This is a way to look at the state without having to wait for a popstate event.

Syntax

let currentState = history.state;

The value of the state property is null until you call pushState() or replaceState().

Examples

The code below logs the value of history.state before using the pushState() method to push a value to the history. The next line logs the value to the console again, showing that history.state now has a value.

// Should be null because we haven't modified the history stack yet
console.log(`History.state before pushState: ${history.state}`);

// Now push something on the stack
history.pushState({name: 'Example'}, "pushState example", 'page3.html');

// Now state has a value.
console.log(`History.state after pushState: ${history.state}`);
