InputEvent.getTargetRanges() - Web APIs 编辑

The getTargetRanges() method of the InputEvent interface returns an array of static ranges that will be affected by a change to the DOM if the input event is not canceled.

Syntax

var staticRanges[] = inputEvent.getTargetRanges()

Parameters

None.

Return value

An array of StaticRange objects.

Examples

Feature Detection

The following function returns true if beforeinput, and thus getTargetRanges, is supported.

function isBeforeInputEventAvailable() {
  return window.InputEvent && typeof InputEvent.prototype.getTargetRanges === "function";
}

Basic usage

The following example selects a contenteditable element and utilises the beforeinput event to log the result of getTargetRanges().

const editableElem = document.querySelector('[contenteditable="true"]');

editableElem.addEventListener('beforeinput', (e) => {
    const targetRanges = e.getTargetRanges();
    console.log(targetRanges);
})
