Use JSON output from Flickr to display images from search

I need to display the images on my site from a JSON request.

I have the JSON:

https://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=6a970fbb976a06193676f88ef2722cc8&text=sampletext&sort=relevance&privacy_filter=1&safe_search=1&per_page=5&page=1&format=json&nojsoncallback=1

And I have the format I need to put the photo URL in: https://www.flickr.com/services/api/misc.urls.html

But I don't know how I would loop through that, I found some examples similar, but I am still having trouble seeing what I need.

I am using JavaScript/jQuery to pull the info.

I figure I would have this in a loop.

CurrentPhotoUrl = 'https://farm'+CurrentPhotoFarm+'.staticflickr.com/'+CurrentPhotoServer+'/'+CurrentPhotoId+'_'+CurrentPhotoSecret+'_n.jpg'

But each of those variables would need to be populated with an value from the element. I would need to loop through all 5 elements that are in the JSON.

Any help on how to create this loop would be greatly appreciated.

I'm not sure if this is the best solution but its is something someone suggested and it worked.

const requestURL = 'https://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=6a970fbb976a06193676f88ef2722cc8&text=sampletext&sort=relevance&privacy_filter=1&safe_search=1&per_page=5&page=1&format=json&nojsoncallback=1'

$.ajax(requestURL)
  .done(function (data) {
    data.photos.photo.forEach(function (currentPhoto) {

      console.log('https://farm'+currentPhoto.farm+'.staticflickr.com/'+currentPhoto.server+'/'+currentPhoto.id+'_'+currentPhoto.secret+'_n.jpg')

    })
  })

Varun's solution worked for me as well. I don't know which one is better but I thought I would post this as well since it looks like they were done fairly differently.

This answer assumes your json data will not change. So inside a .js file, set your json to a variable. 

var json = <paste json here>;
// the photos are inside an array, so use forEach to iterate through them
json.photos.photo.forEach((photoObj) => {
    // the photo will render via an img dom node
    var img = document.createElement('img');
    var farmId = photoObj.farm;
    // you can fill out the rest of the variables ${} in the url
    // using the farm-id as an example
    img.src = `https://farm${farmId}.staticflickr.com/${serverId}/${id}_${secret}.jpg`
    // add the image to the dom
    document.body.appendChild(img);
}

Inside your html file that contains a basic html template, load this javascript file via a script tag, or just paste it inside a script tag.

If you want to get the json from the web page and assuming you have the jquery script loaded...

$.ajax({
        type: 'GET',
        url: <flicker_url_for_json>,
        success: (response) => {
            // iterate through json here
        },
        error: (error) => {
            console.log(error);
        }
    });

Try this code

var n = JSON.parse(x)  //x is the json returned from the url.
var _s = n.photos.photo;
for(var z = 0 ; z < n.photos.photo.length ; z++)
{
   var CurrentPhotoUrl = 'https://farm'+_s[z]['farm']+'.staticflickr.com/'+_s[z]['server']+'/'+_s[z]['id']+'_'+_s[z]['secret']+'_n.jpg'
   console.log(CurrentPhotoUrl);  
}

Edit ( With actual JQUERY AJAX call )

    var n ='';
 $.ajax({url: "https://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=6a970fbb976a06193676f88ef2722cc8&text=sampletext&sort=relevance&privacy_filter=1&safe_search=1&per_page=5&page=1&format=json&nojsoncallback=1", success: function(result){

        console.log(result);
        n = result;
        var _s = n.photos.photo;
        for(var z = 0 ; z < n.photos.photo.length ; z++)
        {
           var CurrentPhotoUrl = 'https://farm'+_s[z]['farm']+'.staticflickr.com/'+_s[z]['server']+'/'+_s[z]['id']+'_'+_s[z]['secret']+'_n.jpg'
           console.log(CurrentPhotoUrl);  
        }  


    }});

Output:
