It can only be used in the context of a web app that uses\n[`IFRAME`](/apps-script/reference/html/sandbox-mode#properties).\nIt is not intended for use with sidebars and dialogs in an add-on or\ncontainer-script context. For more information, see the\n[guide to using browser\nhistory in web apps](/apps-script/guides/web#web_apps_and_browser_history). \n\n### Methods\n\n| Method | Return type | Brief description |\n|----------------------------------------------------------------------|-------------|----------------------------------------------------------------------------------------------------------------------|\n| [push(stateObject, params, hash)](#push(Object,Object,String)) | `void` | Pushes the provided state object, URL parameters and URL fragment onto the browser history stack. |\n| [replace(stateObject, params, hash)](#replace(Object,Object,String)) | `void` | Replaces the top event on the browser history stack with the provided state object, URL parameters and URL fragment. |\n| [setChangeHandler(function)](#setChangeHandler(Function)) | `void` | Sets a callback function to respond to changes in the browser history |\n\nDetailed documentation\n----------------------\n\n### `push(stateObject, params, hash)`\n\nPushes the provided state object, URL parameters and URL fragment onto the browser history\nstack. The state object is a simple JavaScript Object that is defined by the developer and can\ncontain any data relevant to the app's current state. This method is analogous to the\n[pushState()](https://developer.mozilla.org/en-US/docs/Web/API/History_API#The_pushState()_method)\nJavaScript method. \n\n### Index.html\n\n```html\nvar now = new Date();\nvar state = {\n 'timestamp': now.getTime()\n};\nvar params = {\n 'options': \"none\"\n};\ngoogle.script.history.push(state, params, \"anchor1\");\n```\n\n#### Parameters\n\n| Name | Type | Description |\n|---------------|----------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `stateObject` | `Object` | An developer-defined object to be associated with a browser history event, and which resurfaces when the state is popped. Typically used to store application state information (such as page data) for future retrieval. |\n| `params` | `Object` | An object containing URL parameters to associate with this state. For example, `{foo: \"bar\", fiz: \"baz\"}` equates to `\"?foo=bar&fiz=baz\"`. Alternatively, arrays can be used: `{foo: [\"bar\", \"cat\"], fiz: \"baz\"}` equates to `\"?foo=bar&foo=cat&fiz=baz\"`. If null or undefined, the current URL parameters are not changed. If empty, the URL parameters are cleared. |\n| `hash` | `String` | The string URL fragment appearing after the '#' character. If null or undefined, the current URL fragment is not changed. If empty, the URL fragment is cleared. |\n\n*** ** * ** ***\n\n*** ** * ** ***\n\n### `replace(stateObject, params, hash)`\n\nReplaces the top event on the browser history stack with the provided (developer-defined) state\nobject, URL parameters and URL fragment. This is otherwise identical to\n[push()](#push(Object,Object,String)). \n\n### Index.html\n\n```html\nvar now = new Date();\nvar state = {\n 'timestamp': now.getTime()\n};\nvar params = {\n 'options': \"none\"\n};\ngoogle.script.history.replace(state, params, \"anchor1\");\n```\n\n#### Parameters\n\n| Name | Type | Description |\n|---------------|----------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `stateObject` | `Object` | An developer-defined object to be associated with a browser history event, and which resurfaces when the state is popped. Typically used to store application state information (such as page data) for future retrieval. |\n| `params` | `Object` | An object containing URL parameters to associate with this state. For example, `{foo: \"bar\", fiz: \"baz\"}` equates to `\"?foo=bar&fiz=baz\"`. Alternatively, arrays can be used: `{foo: [\"bar\", \"cat\"], fiz: \"baz\"}` equates to `\"?foo=bar&foo=cat&fiz=baz\"`. If null or undefined, the current URL parameters are not changed. If empty, the URL parameters are cleared. |\n| `hash` | `String` | The string URL fragment appearing after the '#' character. If null or undefined, the current URL fragment is not changed. If empty, the URL fragment is cleared. |\n\n*** ** * ** ***\n\n### `setChangeHandler(function)`\n\nSets a callback function to respond to changes in the browser history. The callback function\nshould take only a single [event object](#eventObject) as an argument.\n\n### Index.html\n\n```html\ngoogle.script.history.setChangeHandler(function (e) {\n console.log(e.state);\n console.log(e.location.parameters);\n console.log(e.location.hash);\n\n // Adjust web app UI to match popped state here...\n});\n```\n\n#### Parameters\n\n| Name | Type | Description |\n|------------|------------|----------------------------------------------------------------------------------------------------------------------------------|\n| `function` | `Function` | a client-side callback function to run upon a history change event, using the [event object](#eventObject) as the only argument. |\n\n#### Event object\n\n| Fields ||\n|--------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `e.state` | The state object associated with the popped event. This object is identical to the state object that used in the corresponding [push()](#push(Object,Object,String)) or [replace()](#replace(Object,Object,String)) method that added the popped state to the history stack. ``` {\"page\":2, \"name\":\"Wilbur\"} ``` |\n| `e.location` | A [location object](/apps-script/guides/html/reference/url#locationObject) associated with the popped event ``` {\"hash\":\"\", \"parameter\":{\"name\": \"alice\", \"n\": \"1\"}, \"parameters\":{\"name\": [\"alice\"], \"n\": [\"1\", \"2\"]}} ``` |\n\n*** ** * ** ***"]]
