javascript - 选定的文本索引

Question

我正在尝试使用 javascript/jquery 查找文本索引，但我没有得到确切的解决方案。

考虑文本是这样的......

 Hi all. hello world. Hi all. Hello world.Hi all. hello world. Hi all. Hello world.Hi all. hello world. Hi all. Hello world.Hi all. hello world. Hi all. Hello world.Hi all. hello world. Hi all. Hello world.Hi all. hello world. Hi all. Hello world.Hi all. hello world. Hi all. Hello world.Hi all. hello world. Hi all. Hello world.Hi all. hello world. Hi all. Hello world.Hi all. hello world. Hi all. Hello world.

如何获取任意行中所选“Hello”单词的确切位置？ 我尝试了indexOf，但它给了我第一个hello文本索引。 请任何人提出解决方案。

提前致谢。
