Given a post title, how to get the permalink of the post in javascript code?

[Unparalleled-Calvin]

I am writing my hexo plugin whose tag format looks like {% book_card [post_title] %}. I am confused about how to get the permalink of the post because I want to generate a hyperlink to my post from the title given by the user.
I have noticed that hexo offers tags like post_link to help users convet title to link, but js code can't utilize this gadget. Do you have any ideas ? Any help will be appreciated, thx.

btw, the version I'm using now is 6.3.0.

Thank you for your reply!

const log = require('hexo-log')({ 'debug': false, 'slient': false });

...

function tagTemplate(book_name, author_name, read_time, short_comment, pic_path) {
    hexo.locals.get('posts').forEach((v, i) => {
        log.info(v.title);
    })
    tag = `...`
    return tag
}

hexo.extend.tag.register('book_card', function (args) {
    let [book_name, author_name, read_time, short_comment, pic_path] = args
    return tagTemplate(book_name, author_name, read_time, short_comment, pic_path)
})

...

Here are a few of lines in my code. When I use hexo cl && hexo s to restart the engine, the log only prints part of my posts' titles maybe 2 or 3. I guess it is caused by concurrent processing or some processing order. What should I do now?
