The Main Interface

This code contains the interface of the application. To create this just write these block of code inside the text editor and save this as index.html.

  1. <!doctype html>
  2. <html lang="en">
  3. <head>
  4. <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1"/>
  5. <link rel="stylesheet" type="text/css" href="css/bootstrap.css "/>
  6. </head>
  7. <nav class="navbar navbar-default">
  8. <div class="container-fluid">
  9. <a class="navbar-brand" href="">Sourcecodester</a>
  10. </div>
  11. </nav>
  12. <div class="col-md-3"></div>
  13. <div class="col-md-6 well">
  14. <h3 class="text-primary">Javascript - How to Upload Images Using jQuery</h3>
  15. <hr style="border-top:1px dotted #ccc;"/>
  16. <div id = "preview" style = "width:500px; height :300px; border:1px solid #000;"></div>
  17. <input type = "file" id = "file" name = "photo" accept="image/*"/>
  18. </center>
  19. </div>
  21. <script src="js/jquery-3.2.1.min.js"></script>
  22. <script src="js/script.js"></script>
  23. </body>
  24. </html>

Creating the Script

This code contains the script of the application. This code will upload the image file and display as a preview for checking. To do this just copy and write these block of codes as shown below inside the text editor and save it as script.js inside the js folder.

  1. $(document).ready(function(){
  2. $pic = $('<img id = "image" width = "100%" height = "100%"/>');
  3. $("#file").change(function(){
  4. var files = !!this.files ? this.files : [];
  5. if(!files.length || !window.FileReader){
  6. $("#image").remove();
  7. }
  8. if(/^image/.test(files[0].type)){
  9. var reader = new FileReader();
  10. reader.readAsDataURL(files[0]);
  11. reader.onloadend = function(){
  12. $pic.appendTo("#preview");
  13. $("#image").attr("src", this.result);
  14. }
  16. }
  17. });
  18. });
