Answer 1

I solved my problem with Friend's Help. My solution is:

Notice: I set Timeout 10000(10 seconds) for complete load page.

var page = require('webpage').create();

page.open("https://sample.com", function(){
    page.evaluate(function(){
        var i = 0,
        oJson = jsonData,
        sKey;
        localStorage.clear();

        for (; sKey = Object.keys(oJson)[i]; i++) {
            localStorage.setItem(sKey,oJson[sKey])
        }
    });

    page.open("https://sample.com", function(){
        setTimeout(function(){
         page.render("screenshoot.png") 
            // Where you want to save it    
           console.log(page.content); //page source
            // You can access its content using jQuery
            var fbcomments = page.evaluate(function(){
                return $("body").contents().find(".content") 
            }) 
            phantom.exit();
        },10000)
    });    
});

localStorage for a particular domain is only available when you open a page on that domain. You can

1. open some URL on the domain you're interested in,
2. change localStorage according to your needs,
3. open your target URL on the same domain.

This can look like this:

page.open("https://sample.com/asdfasdf", function(){
    page.evaluate(function(){
        localStorage.setItem("something", "whatever");
    });

    page.open("https://sample.com", function(){
        setTimeout(function(){
            // Where you want to save it    
            page.render("screenshoot.png")  
            // You can access its content using jQuery
            var fbcomments = page.evaluate(function(){
                return $("body").contents().find(".content") 
            }) 
            phantom.exit();
        },1000)
    });    
});

It's also possible not to open a full page in step 1. You can also use dummy page with some URL.

page.setContent("", "https://sample.com"); // doesn't actually open any page

page.evaluate(function(){
    localStorage.setItem("something", "whatever");
});

page.open("https://sample.com", function(){
    setTimeout(function(){
        // Where you want to save it    
        page.render("screenshoot.png")  
        // You can access its content using jQuery
        var fbcomments = page.evaluate(function(){
            return $("body").contents().find(".content") 
        }) 
        phantom.exit();
    }, 1000)
});
