Use YQL to resolve the front-end crawl page and resolve

When writing code today, in order to save back-end performance, you want to use a front-end browser to crawl a page and parse out some of the content.

Because cross-domain is involved, it is necessary to use the JSONP, but JSONP need to return JSON format, and we need to crawl the content of a Web page, so the direct use of JSONP will be an error. So we need to use YQL to help us parse the HTML content into JSON format.

1 $.ajax ({  2    URL: "HTTP://QUERY.YAHOOAPIS.COM/V1/PUBLIC/YQL" 3  , type: ' Jsonp ' ) 4  , data: {  5    Q: "SELECT * from HTML where url=\" Http://www.baidu.com/\ "",  6< /c11>    format: "JSON" 7   }  8  , Success:  (resp) + = { 9    Console.log (resp)   });

The URL is fixed, the address for the YQL service, and format is the one you want to parse. Q is the YQL statement, where HTML is the pre-conversion format.
