由 血红的双手。 提交于 2021-02-07 10:45:25
问题 I'm using cheerio, request and Node.js. When I run the script below, it outputs names in a wrong order. I believe that it's caused by asynchronous nature of it, how can I make it work in the "right" order?

问题 I am writing an application in node.js that will navigate to a website, click a button on the website, and then extract certain pieces of data from the website. All is going well except for the button-clicking aspect. I cannot seem to simulate a button click. I'm extremely new at this, so I'd appreciate any suggestions y'all have! Sadly I've scoured the internet looking for a solution to this issue and have been unable to find one. I have used .click() and .bind('click, ...) in a .js file
