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
v 1
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
