我把源码中的 getEditorRange, setSelectionFocus 扒下来实现了

const getEditorRange = (vditor):Range => {
    let range: Range;
    const element = vditor[vditor.currentMode].element;
    if (getSelection().rangeCount > 0) {
        range = getSelection().getRangeAt(0);
        if (element.isEqualNode(range.startContainer) || element.contains(range.startContainer)) {
            return range;
        }
    }
    if (vditor[vditor.currentMode].range) {
        return vditor[vditor.currentMode].range;
    }
    element.focus();
    range = element.ownerDocument.createRange();
    range.setStart(element, 0);
    range.collapse(true);

    return range;
};

const setSelectionFocus = (range: Range) => {
    const selection = window.getSelection();
    selection.removeAllRanges();
    selection.addRange(range);
}

我为什么要扒下来？一开始我是采用导入的方式的

import { getEditorRange } from 'vditor/src/ts/util/selection';

引用 getEditorRange 后提示我找不到 VDITOR_VERSION，然后我引用如下

import { VDITOR_VERSION } from 'vditor/src/ts/constants';
import { getEditorRange } from 'vditor/src/ts/util/selection';

还是报错。。。。无奈只好 copy 到方法中来了

求更好的实现方法
