HTML：
<div ng-controller="TopMenuCtrl">
<button class="btn" ng-click="isCollapsed = !isCollapsed">Toggle collapse</button>
<input type="file" ng-model="filepick" ng-change="pickimg()" multiple />
<output id="list"></output>
</div>
JavaScript的：
angular.module('plunker',['ui.bootstrap']);
function TopMenuCtrl($scope) {
$scope.pickimg = function() {
alert('a');
};
}
首先，在HTML中，定义Javascript for forchange，如下所示：
<input ng-model="photo"
onchange="angular.element(this).scope().file_changed(this)"
type="file" accept="image/*" />
$scope.file_changed = function(element) {
$scope.$apply(function(scope) {
var photofile = element.files[0];
var reader = new FileReader();
reader.onload = function(e) {
// handle onload
};
reader.readAsDataURL(photofile);
});
};
