只读属性 Range.endOffset 返回代表 Range 结束位置在 Range.endContainer 中的偏移值的数字。
如果 endContainer 的 Node 类型为 Text, Comment，或 CDATASection，偏移值是 endContainer 节点开头到 Range 末尾的总字符个数。对其他类型的 Node ， endOffset 指 endContainer 开头到 Range 末尾的总 Node 个数。如需修改 endOffset 的值， 使用 Range.setEnd 方法。
语法
endRangeOffset = range.endOffset;
示例
var range = document.createRange(); range.setStart(startNode,startOffset); range.setEnd(endNode,endOffset); endRangeOffset = range.endOffset;
