[Hexo] how do I call the variables provided by Hexo in the page javascript?

excuse me:
about the use of Hexo blog template variables.
how do I call the variables provided by Hexo in the page javascript? Such as "page.title".
tried to use the interpolation method "{{}}" himself, but failed.
also hope to get an answer, thank you!
