{{ APIRef("History API") }}

The state read-only property of the {{domxref("PopStateEvent")}} interface represents the state stored when the event was created.

Practically it is a value provided by the call to {{domxref("history.pushState()")}} or {{domxref("history.replaceState()")}}

Value

An object, or null.

Examples

The code below logs the value of state when using the {{domxref("History.pushState","pushState()")}} method to push a value to the history.

// Log the state of
addEventListener("popstate", (event) => {
  console.log("State received: ", event.state);
});

// Now push something on the stack
history.pushState({ name: "Example" }, "pushState example", "page1.html");
history.pushState(
  { name: "Another example" },
  "pushState example",
  "page1.html"
);

This will log:

State received: { name: "Example" }
State received: { name: "Another example" }
