Javascript Question

How do you pass a single quote through a URL?

I'm using Node.js:

var s = 'Who\'s that girl?';
var url = 'http://graph.facebook.com/?text=' + encodeURIComponent(s);

request( url, POST, ...)


This does not work! And Facebook cuts off my text...

Full code:

function postToFacebook(fbid, access_token, data, next){
var uri = 'https://graph.facebook.com/'+String(fbid)+'/feed?access_token='+access_token;
var uri += '&' + querystring.stringify(data);
request({
'method':'POST',
'uri': uri,
},function(err,response,body){
next();
});
};


app.get('/test',function(req,res){
var d = {
'name':'Who\'s that girl?',
'link': 'http://example.com',
'caption': 'some caption...',
'description': 'some description...',
'picture': 'http://i.imgur.com/CmlrM.png',
};
postToFacebook(req.user.fb.id, req.user.fb.accessToken, d);
res.send('done');
});


Facebook gets a blank post on the wall. No text shows. Nothing.

When I log my URI, it is this:

https://graph.facebook.com/1290502368/feed?access_token=2067022539347370|d7ae6f314515c918732eab36.1-1230602668|GtOJ-pi3ZBatd41tPvrHb0OIYyk&name=Who's%20that%20girl%3F&link=http%3A%2F%2Fexample.com&caption=some%20caption...&description=some%20description...&picture=http%3A%2F%2Fi.imgur.com%2FCmlrM.png


Obviously if you take a look at that URL, you see that the single quote is not being encoded correctly.

I'm doing a similar thing (also with Node.js) and first tried using JavaScript's built-in escape() function, but it didn't really work.

Here's how I ended up getting search to work. It might just be a fluke:

 function doMySearch(showTitle) {
     showTitle = escapeShowTitle(showTitle)
     var url = "http://graph.facebook.com/search?q=" + showTitle + "&type=page"
     doSomethingWith(url)
}

function escapeShowTitle(title) {
    title = title.replace(/'/g, "")
    title = escape(title)
    return title
}

doMySearch("America's Funniest home Videos")
