Learning jQuery

Today, I needed to display images received from a JSON file. The JSON file has only the path of the images. So in this post, find jQuery code to display or load images received from JSON file.

Consider, below is the JSON file content. It has products list with name and its image path.

{
   "products": [
      {
         "name": "Levis Blue Denim",
         "imgPath": "images/prods/levisbluedemin01.jpg"
      },
      {
         "name": "Pepe Black Jeans",
         "imgPath": "images/prods/pepeblackjeans01.jpg"
      },
      {
         "name": "Pepe Blue Jeans",
         "imgPath": "images/prods/pepebluejeans01.jpg"
      }
  ]
}

First, read the JSON file using $.getJSON function and then iterate through the received json result. Within the loop, fetch the imgPath property value, set it as image source to <img> tag and append it to a variable.

And once all the products are processed then add the variable value to DOM element in which images needs to be displayed.

$(document).ready(function () {
  var jsonURL = "productList.json";
  $.getJSON(jsonURL, function (json) 
  {
    var imgList= "";

    $.each(json.products, function () {
      imgList += '<li><img src= "' + this.imgPath + '"></li>';
    });

   $('#dvProdList').append(imgList);
  });
});
