Phonsent

Google and Baidu can crawl the web page content data contained in JavaScript. Yes, you read that right. Not only Google, but also Baidu search engine. Luckily Baidu didn't let me down. 

The biggest problem with the web page generated by JavaScript is that the web page content is written into the JavaScript code, which makes crawler unable to read the content in JS when accessing the web page, so nothing is captured.
