当我点击鼠标时,我试图从该位置的内容可编辑div中提取单个单词.例如:

Lorem ipsum dolor sit amet, cons|ectetur adipiscing elit. Cras vestibulum gravida

            var caretPos = 0, containerEl = null, sel, range;
            if (window.getSelection) {
                sel = window.getSelection();
                if (sel.rangeCount) {
                    range = sel.getRangeAt(0);
                    if (range.commonAncestorContainer.parentNode == this) {
                        caretPos = range.endOffset;
                    }
                }
            } else if (document.selection && document.selection.createRange) {
                range = document.selection.createRange(); …
