如何读取AngularJS文件？ [英] How to read a file in AngularJS?

问题描述

是否有可能在AngularJS读取文件？我想将文件放入一个HTML5画布作物。我想用指令？

Hey guys, is it possible to read files in AngularJS? I want to place the file into an HTML5 canvas to crop. I was thinking of using a directive?

这是javscript code我希望把我的指令：

This is the javscript code I want to put into my directive:

function readURL(input) {

    if (input.files && input.files[0]) {
        var reader = new FileReader();

        reader.onload = function (e) {
            $('#blah').attr('src', e.target.result);
        }

        reader.readAsDataURL(input.files[0]);
    }
}

谢谢！

推荐答案

是的，指令是一个正确的方式，但它看起来有点不同：

Yes , directives is a right way, but it looks little bit different:

.directive("ngFileSelect",function(){    
  return {
    link: function($scope,el){          
      el.bind("change", function(e){          
        $scope.file = (e.srcElement || e.target).files[0];
        $scope.getFile();
      });          
    }        
  }
