角度上传多个文件

angularjs

我遇到的情况是，我有一个表格，其中有一行，其中有两个文本字段条目，我必须上载该行的文件，并且这种行可以是“
N”，然后是可以在整个表单中输入的主文件，而这些文件是表单的一部分，我必须在单击保存按钮后立即提交所有这些文件。

我有点被ng-upload困扰，它需要一个api调用，而对于这种形式，我真的不能超过一个api调用。示例html代码如下：

<!DOCTYPE html>

<html>



<head>

  <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />

  <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

  <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

</head>



<body>



  <form editable-form name="xyzForm" ng-submit="create(model)">

    <label>Tags: </label><input class="col-xs-12 col-md-12" ng-model="model.tags" type="text" name="Tags">

    <label>Notes: </label> <input class="col-xs-12 col-md-11" ng-model="model.notes" type="text" name="notes">

    <table class=" col-xs-3 col-md-11 table" border="1px solid red;">

      <thead>

        <tr>

          <th>Product</th>

          <th>Manufacturer</th>

          <th>Location</th>

          <th>Specification</th>

          <th></th>

        </tr>

      </thead>

      <tbody>

        <tr ng-repeat="itemRow in item.singleItem">

          <td><input type="text" class="xdTextBox" name="itemRow.name" ng-model="model.itemRow[$index].name" /></td>

          <td><input type="text" class="xdTextBox" name="itemRow.manufacturer" ng-model="model.itemRow[$index].manufacturer" /></td>

          <td><input type="text" class="xdTextBox" name="itemRow.location" ng-model="model.itemRow[$index].location" /></td>

          <td><i class="pull-left glyphicon glyphicon-upload"><input type="file" name="itemRow.doc" ng-model="model.itemRow[$index].doc" multiple=false></i></td>

          <td><i class="pull-left glyphicon glyphicon-remove"></i></td>

        </tr>



      </tbody>

      </span>

    </table>



    <label>Product Spec: </label><input type="file" ng-model="prefabdoc" multiple="true" ngf-maxsize="15000000" />

  </form>



</body>

这是文件值绑定指令示例..

http://plnkr.co/edit/B13t84j5IPzINMh1F862?p=preview

js代码是：

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

app.controller('MainCtrl', function($scope) {
  $scope.name = 'World';
  $scope.files = []; 
  $scope.upload=function(){
    alert($scope.files.length+" files selected ... Write your Upload Code");

  };
});


app.directive('ngFileModel', ['$parse', function ($parse) {
    return {
        restrict: 'A',
        link: function (scope, element, attrs) {
            var model = $parse(attrs.ngFileModel);
            var isMultiple = attrs.multiple;
            var modelSetter = model.assign;
            element.bind('change', function () {
                var values = [];
                angular.forEach(element[0].files, function (item) {
                    var value = {
                       // File Name 
                        name: item.name,
                        //File Size 
                        size: item.size,
                        //File URL to view 
                        url: URL.createObjectURL(item),
                        // File Input Value 
                        _file: item
                    };
                    values.push(value);
                });
                scope.$apply(function () {
                    if (isMultiple) {
                        modelSetter(scope, values);
                    } else {
                        modelSetter(scope, values[0]);
                    }
                });
            });
        }
    };
}]);

HTML代码是：

<!DOCTYPE html>
<html ng-app="myApp">

  <head>
    <meta charset="utf-8" />
    <title>AngularJS Plunker</title>
    <script>document.write('<base href="' + document.location + '" />');</script>
    <link href="style.css" rel="stylesheet" />
    <script data-semver="1.4.3" src="https://code.angularjs.org/1.4.3/angular.js" 
        data-require="angular.js@1.4.x"></script>
    <script src="app.js"></script>
  </head>

  <body ng-controller="MainCtrl">
    <p>Hello {{name}}!</p>
    <input type="file" ng-file-model="files" multiple />
    <button type="button" ng-click="upload()">Upload</button>

    <p ng-repeat="file in files">
      {{file.name}}
    </p>
  </body>

</html>
