get source and name of selected file with angularjs

Question

Is there a way to get name, path and size of selected file in input field using angularJS, before uploading it?

<input type="file" ng-model="fileContent" on-read-file="showContent($fileContent)" />

$scope.showContent = function($fileContent){

    $scope.content = $fileContent;

};

Can anyone help to solve this please?

The HTML5 File API will give you a File object for each file that you're attempting to upload. This File object will have a size and name property which will give you the file size in bytes and the name of the file.

There's no property for the physical path to the file on the users machine, though.

You can read more about this on MDN: https://developer.mozilla.org/en-US/docs/Using_files_from_web_applications

More information on the File object here: https://developer.mozilla.org/en-US/docs/Web/API/File

Here's a working example: http://jsfiddle.net/fmeLz9cd/

Given an input of type file with an id fileSelected, here's an example of accessing the properties through the File API:

 $('#fileSelected').on('change', function (evt) {
    var files = $(evt.currentTarget).get(0).files;

    if(files.length > 0) {
        $('#fileName').text(files[0].name);
        $('#fileSize').text(files[0].size);
        $('#filePath').text($('#fileSelected').val());
    }
});

Update

Since you've requested an AngularJS specific example, here's the same code working in an angular app:

http://jsfiddle.net/vyc6jq84/1/

<div ng-app="fileDemo">
    <input type="file" fd-input />
</div>

var app = angular.module('fileDemo', []);

app.directive('fdInput', [function () {
    return {
        link: function (scope, element, attrs) {
            element.on('change', function  (evt) {
                var files = evt.target.files;
                console.log(files[0].name);
                console.log(files[0].size);
            });
        }
    }
}]);
