Upload image using javascript

Question

I\'m trying to get image as Object of javascript on the client side to send it using jQuery

Answer 1

This is what I use and it works great for me. I save the image as a blob in mysql. When clicked, the file upload dialog appears, that is why i set the file input visibility to hidden and set its type to upload image files. Once the image is selected, it replaces the existing one, then I use the jquery post method to update the image in the database.

     

     




  $('img#logo').click(function(){                           
    $('#logoupload').trigger('click');
    $('#logoupload').change(function(e){

      var reader = new FileReader(),
           files = e.dataTransfer ? e.dataTransfer.files : e.target.files,
            i = 0;

            reader.onload = onFileLoad;

             while (files[i]) reader.readAsDataURL(files[i++]);

              });

                function onFileLoad(e) {
                        var data = e.target.result;
                          $('img#logo').attr("src",data);
                          //Upload the image to the database
                           //Save data on keydown
                            $.post('test.php',{data:$('img#logo').attr("src")},function(){

                            });
                            }

                        });
