TherangeEnd property of theTextFormat interface indicates the end position of the text range that needs to be formatted with the given text format.

The following example shows how to use thetextformatupdate event'srangeStart andrangeEnd properties to determine the range of text that needs to be formatted. Note that the event listener callback in this example is only called when using an IME window to compose text.

html

<div></div>

#editor {  height: 200px;  background: #eeeeee;}

const editorEl = document.getElementById("editor");const editContext = new EditContext(editorEl);editorEl.editContext = editContext;editContext.addEventListener("textformatupdate", (e) => {  const formats = e.getTextFormats();  for (const format of formats) {    console.log(      `IME wants to apply formatting between ${format.rangeStart} and ${format.rangeEnd}.`,    );  }});
