Class RangeElement
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
Range 元素
封装了 Element
的封装容器,可能具有开始偏移量和结束偏移量。借助这些偏移,Text
元素中的一组字符可以在搜索结果、文档选择和命名范围中表示。

getElement()
获取与此 RangeElement
相对应的 Element
。
const rangeElement = DocumentApp.getActiveDocument().getSelection().getRangeElements()[0];
// Log debug information about a range element.
Logger.log(`Element type: ${rangeElement.getElement().getType()}`);
if (rangeElement.isPartial()) {
Logger.log(`The character range begins at ${rangeElement.getStartOffset()}`);
Logger.log(
`The character range ends at ${rangeElement.getEndOffsetInclusive()}`,
);
} else {
Logger.log('The entire range element is included.');
}
返回
Element
- 与此 RangeElement
对应的元素
授权
使用此方法的脚本需要获得以下一个或多个范围的授权:
-

-

getEndOffsetInclusive()
获取范围元素中部分范围的结束位置。如果元素是 Text
元素,并且 isPartial()
返回 true
,则偏移量为范围中最后一个字符之前的字符数(即范围中最后一个字符的索引);在任何其他情况下,此方法都会返回 -1
。
返回
Integer
- 对于 Text
元素,是范围中最后一个字符之前的字符数;对于其他元素,为 -1

getStartOffset()
获取范围元素中部分范围的起始位置。如果元素是 Text
元素,并且 isPartial()
返回 true
,则偏移量为范围开始之前的字符数(即范围中第一个字符的索引);在任何其他情况下,此方法都会返回 -1
。
返回
Integer
- 对于 Text
元素,是范围开始前面的字符数;对于其他元素,是 -1
授权

isPartial()
确定此范围元素是涵盖整个元素,还是仅涵盖元素字符的部分选择。您可以分别使用 getStartOffset()
和 getEndOffsetInclusive()
确定部分范围元素范围的开始和结束。
返回
Boolean
- 如果部分包含该元素,则为 true
;如果不包含,则为 false
