phantomjs using open () function to open multiple

问题:

PhantomJS is asynchronous

I got an array of links in the first page，and I need to link each. so I wrote a test. As follows

code :

console.log('Loading a web page');

var page = require('webpage').create();
page.open('http://cd.house.qq.com/', function() {
    var ua = page.evaluate(function() {
        var link = new Array();
        var len =  document.body.getElementsByTagName("object").length;
        for( var i = 0; i < len; i++ ){
            link[i] = document.body.getElementsByTagName("object")[i].nextSibling.getAttribute("href");
        }
        return link;
    });
    console.log(ua.length);

    page.open(ua[0], function(){
        console.log('000000000');
    }); 
    page.open(ua[1], function(){
        console.log('11111111');
    });
});

print :

$ phantomjs p.js 
Loading a web page
9
11111111

Q: when Asynchronous, why do not perform array 0
