How to loop through json objects using Jquery or javascript

These days handling json object is very essential in all kinds of applications , this post would help you to do that in very easy way .There are many way to handle json and some of them are described bellow .My aim is to help around the newbees here in json and javascript .


following code snippet will help you to call a remote end point and loop through the response json using jquery

Using Jquery


$.getJSON(requestURL, {
'apikey' : apiKey,
if (data.results && data.results.length > 0) {

$.each(data.results, function(i, rep) {
// do looping stuff here - i=index and rep is value
});

} else {
// else part
}
});


'zip' : zipcode,
}, function(data){

in pure java script we can loop through json object in two ways. If we are not concern about the order in which loop through we can go for a for each loop . Some other situations we must need to keep the order or we mus loop in sequential order in that case we must use standard for loop as given bellow


var info = {
"full_name" : "sudeep cv",
"title" : "Java developer",
"links" : {
    "blog"     : "http://iviewsource.com",
    "facebook" : "https://www.facebook.com/sudeepcv90",
"twitter"  : "https://twitter.com/sudeepcv",
"github"  : "https://github.com/sudeepcv",
"web"  : "http://sudeep-cv.tk/"
}
};

var output = "";

for ( key in info.links ) {
if (info.links.hasOwnProperty(key)) {

console.log( info.links[key] );

} //if the links has the key property
} // for...go through each link


or


for (var i = 0; i <= info.links.length; i++) {
for (key in info.links[i]) {
if (info.links[i].hasOwnProperty(key)) {

console.log( info.links[i][key] );

} // hasOwnProperty check
} // for each object
} //for each array element
