闲来无事爬了下通讯录 试手 jsdom

var jsdom = require(‘jsdom‘)
    ,fs = require(‘fs‘)
process.stdin.setEncoding(‘utf8‘);

var html = ‘‘
process.stdin.on(‘readable‘, function() {
    var chunk = process.stdin.read();
    if (chunk !== null) html += chunk
});
var userlist = require(‘./userlist.json‘)
    ,userHash = JSON.parse(JSON.stringify(userlist) )

process.stdin.on(‘end‘, function() {

    process.stdout.write(‘\n‘);
    jsdom.env(html,
      function (errors, window) {
        var list = []
        var l = window.document.querySelectorAll(‘#userlist tr‘)
        for (var i = 0 ; i < l.length ;i ++ ){
            var li = l[i].getElementsByTagName(‘td‘)
            if (!li || li.length < 8) continue
            var user_id = li[0].textContent
            var user = {
                "name" : li[2].textContent
                , "dep" : li[4].textContent

                , "phone" : li[6].textContent
                , "qq" : li[7].textContent.trim()
                }
            if (user_id in userlist ) {
                delete userHash[user_id]
                continue
            }
            user.join = +new Date()
            userlist[user_id] = user
            process.stdout.write(‘\n 入职:‘ + JSON.stringify(user))

        }

            fs.writeFile(‘./leaves.json‘ , JSON.stringify(leaves ,null , 4) )
            process.stdout.write(‘\n  离职:‘ + quits)
        }
        fs.writeFile(‘./userlist.json‘ , JSON.stringify(userlist ,null , 4) )
        process.stdout.write(‘\nend‘);
      }
    )
})
