# TXDocumentViewer Object

> Legacy browser-global entry point for the TX Text Control Document Viewer. The browser exposes this namespace as `window.TXDocumentViewer`. Before initialization it provides the init() method. After initialization it references the same object as the most recently created DocumentViewerController while retaining the `init()` method for compatibility. The controller's public methods, properties, and namespaces are therefore available directly through `window.TXDocumentViewer` after initialization. Modern integrations should use the ES module or the DocumentViewerElement custom element instead.

### Description

Legacy browser-global entry point for the TX Text Control Document Viewer. The browser exposes this namespace as `window.TXDocumentViewer`. Before initialization it provides the [init()](https://docs.textcontrol.com/ds-server/reference/javascript-document-viewer/txdocumentviewer/llms-full.txt) method. After initialization it references the same object as the most recently created [DocumentViewerController](https://docs.textcontrol.com/ds-server/reference/javascript-document-viewer/documentviewercontroller/llms-full.txt) while retaining the `init()` method for compatibility. The controller's public methods, properties, and namespaces are therefore available directly through `window.TXDocumentViewer` after initialization. Modern integrations should use the ES module or the [DocumentViewerElement](https://docs.textcontrol.com/ds-server/reference/javascript-document-viewer/documentviewerelement/llms-full.txt) custom element instead.

### Syntax

```javascript
TXDocumentViewer
```

### Examples

The following example demonstrates `TXDocumentViewer` in a practical Document Viewer workflow. The TXDocumentViewer JavaScript object provides a public API to manipulate the document viewer via JavaScript functions in the browser.

```javascript
TXDocumentViewer.addEventListener("annotationsChanged", function() {
    console.log("The Document Viewer annotations changed.");
});
```

## In This Section

- [Javascript: TXDocumentViewer.init Method](https://docs.textcontrol.com/ds-server/reference/javascript-document-viewer/txdocumentviewer/init-method/llms-full.txt): Initializes a controller through the legacy browser-global API. The method creates a DocumentViewerController for the supplied container. If `viewerSettings.documentData` is provided, the document is loaded during initialization. The global then references the same controller instance and keeps this method available as `TXDocumentViewer.init()`. The controller's public API can subsequently be accessed directly through `TXDocumentViewer`.
