Previously, the Chrome Extension Video Download Helper has been accepted by Google Web Store and Utopian. Today, I have spent some time adding the support of parsing the video URLs from pearvideo.com

Check the HTML source from:

http://www.pearvideo.com/video_1050733

We can see that the video source is in the text of Javascript code:

Therefore, we can customize the search using Regular expression, the JS code has been added to the plugin:

    if (domain.includes("pearvideo.com")) {
        if (!ValidURL(video_url)) {
            var re = /srcUrl="([^"\']+)"/gi;
            var found = re.exec(html);                        
            var video_url_arr = [];
            while (found != null) {
                var tmp_url = CheckURL(found[1]);
                if (ValidURL(tmp_url)) {
                    video_url_arr.push(tmp_url);    
                }                            
                found = re.exec(html);
            }
            if (valid_domain) {                
                if (video_url_arr.length > 0) {
                    chrome.runtime.sendMessage({
                        action: "getSource",
                        source: JSON.stringify(video_url_arr)
                    });                          
                } else {
                    chrome.runtime.sendMessage({
                        action: "getSource",
                        source: JSON.stringify(CheckURL(video_url))
                    });                              
                }
            }
        }
    }
