js callack still returning undefined ---

[wasiu razak]

hi , am have tried all possible ways to make this work , but it seem to not work 

the idea is pass each ,news item to the citifmonlinedetail() to get the detail info and pass to json ,and send to database 

var url3 = 'http://citifmonline.com/category/news/';

function citifmonlineDetail(url, callback) {

setTimeout(function() {

request(url, function(error, response, html) {

var detail = "";

if (!error) {

$ = cheerio.load(html);

$('.entry p').each(function(index, paragraphs) {

console.log($(paragraphs).text());

var a = $(paragraphs).text();

detail = detail.concat(a + " ");

});

callback(detail);

}

});

}, 3000);

}

request(url3, function(error, response, html) {

if (!error) {

$ = cheerio.load(html);

$('div.post-listing article').each(function(index, listings) {

var image = $(listings).find('.post-thumbnail a img');

var title = $(listings).find('.post-title a');

var description = $(listings).find('.entry p');

var link = $(title).attr('href');

// var details = 

var metadata = {

image: $(image).attr('src'),

title: $(title).text(),

url: $(title).attr('href'),

description: $(description).text(),

detail:citifmonlineDetail(link, function(result) { // here we pass each news item link to get the detail news information

var value = result;

return value;

}),

};

console.log("---------------------------------------------------------------------------");

console.log(metadata);

});

}

});

running only citifmonlinedetail() 

alone works , but combination of my overall logic return json with only the detail object returning  undefined and later spits it out corrupting my json object concatenation ,any help is very appreciated

Hi!

You cannot set metadata.detail using the return value of citifmonlineDetail function.

You must:

var metadata = {

// initialize, skipping detail

};

// then set the detail using the callback

citifmonlineDetail(link, function (result) {

     metadata.detail = result;

// then in this callback, you can use the console

    console.log("----");

    console.log(metadata); // or console.dir(metadata) or console.log(JSON.stringify(metadata, null, 4)

});
