Image wont load when clicked for larger image

2019-08-26 08:26发布

For the assignment I'm doing, you need to get a modal pop out to have larger sizes of the photo appear and you can also click the x to go back. The x wont go back for me and I also can't seem to load the images. Is there anything wrong with my code that I'm missing? I've been staring at my code for ages now. Also we have to make a recently viewed page where the thumbnails are small. Whatever ones you click to enlarge and to appear on the side bar in little thumbnails. Does anyone have any clue how to do this? I can't seem to find any tutorials on it :(

$(function() {
  $(".request").on("click", function() {
    let searchText = $(this).children().text();
    let API_KEY = "MY API KEY";
    let tennisStr = "https://api.flickr.com/services/rest/?method=flickr.photos.search&tags=" + searchText + "&per_page=15&format=json&nojsoncallback=1&api_key=" + API_KEY;
    let photos = [];
    let nrequest;
    let nreceived;

    $.get(tennisStr, function(data) {
      fetchPhoto(data);
    });

    function fetchPhoto(data) {
      nrequest = data.photos.photo.length;
      nreceived = 0;
      for (let i = 0; i < data.photos.photo.length; i++) {
        let photoObj = {
          id: data.photos.photo[i].id,
          title: data.photos.photo[i].title
        }
        photos.push(photoObj);
        getSizes(photoObj);
      }

      function getSizes(photoObj) {
        let getSizesStr = "https://api.flickr.com/services/rest/?method=flickr.photos.getSizes&format=json&nojsoncallback=1&api_key=" + API_KEY + "&photo_id=" + photoObj.id;
        $.get(getSizesStr, function(data) {
          nreceived++;
          photoObj.file = data.sizes.size[3].source;
          photoObj.full = data.sizes.size[data.sizes.size.length - 1].source;
          if (nreceived == nrequest) {
            display(photos);
          }
        });
      }

      function display(photos) {
        let htmlStr = "";
        for (let i = 0; i < photos.length; i++) {
          htmlStr += `<figure data-full="${photos[i].full}"><img src = "${photos[i].file}"><figcaption>${photos[i].title}</figcaption></figure>`;
        }
        $("#flickrphoto").html(htmlStr);
        $('figure').each(function (index){
            $(this).click(function(){
                $('#modal-container').css('display', 'block');
                $('modal-content').attr('src', $(this).attr('data-full'));
            });
        });
        $("#modal-close").click(function(){

            $('#modal-content').attr('src', '');

Also is there any reason that flexbox would push the photos over the other two columns?

Thanks for your help! :)

You forgot the # in the jQuery selector function.

Change $('modal-content') to $('#modal-content').


In order to render the recent viewed images I've updated the getSizes function like this:

function getSizes(photoObj) {
  let getSizesStr = "https://api.flickr.com/services/rest/?method=flickr.photos.getSizes&format=json&nojsoncallback=1&api_key=" + API_KEY + "&photo_id=" + photoObj.id;
  $.get(getSizesStr, function(data) {
    nreceived++;
    photoObj.thumbnail = data.sizes.size[2].source; // "label": "Thumbnail",
    photoObj.file = data.sizes.size[3].source; // "label": "Small",
    photoObj.full = data.sizes.size[data.sizes.size.length - 1].source; // "label": "Original",
    if (nreceived == nrequest) {
      display(photos);
    }
  });
}

As you can see, I've added photoObj.thumbnail:

photoObj.thumbnail = data.sizes.size[2].source;

I declared a global array variable called viewedImages to store the recent viewed images.

let viewedImages = [];

I've added a new function to render the recent viewed images called showViewedImages():

function showViewedImages() {
  var len = viewedImages.length, html = "";
  for (var i = 0; i < len; i++) {
    html += "<li><img src=\"";
    html += viewedImages[i];
    html += "\" /></li>";
  }
  $("#viewedImagesList").html(html);
}

Throug the https://api.flickr.com/services/rest/?method=flickr.photos.getSizes&format=json&nojsoncallback=1&api_key=39417c145483a7fb3ee91c5fe5bc93fe&photo_id=41465072422 URL method you get all you need.

This is the JSON response:

Something like this:

$(function() {

    $.get(tennisStr, function(data) { // jQuery.get() method wich runs $.ajax() function with GET request type by default.
      fetchPhoto(data); // Inside the anonymous function call the fetchPhoto function with the current data from the API url requested. 
    });

    function fetchPhoto(data) {

        }
        photos.push(photoObj);

        $.get(getSizesStr, function(data) {
          nreceived++;
          photoObj.thumbnail = data.sizes.size[2].source; // "label": "Thumbnail",

        }
        $("#flickrphoto").html(htmlStr);
        $('figure').each(function(index) {
