您好，我想知道是否有一种方式预览图像之前我上传他们使用angularjs？我使用这个库。

谢谢。这里是我的代码：
template.html
<div ng-controller="picUploadCtr">
<form>
<input type="text" ng-model="myModelObj">
<input type="file" ng-file-select="onFileSelect($files)" >
<input type="file" ng-file-select="onFileSelect($files)" multiple>
</form>
</div>
controller.js
.controller('picUploadCtr',function($scope,$http,$location,userSettingsService) {
$scope.onFileSelect = function($files) {
//$files: an array of files selected,each file has name,size,and type.
for (var i = 0; i < $files.length; i++) {
var $file = $files[i];
$http.uploadFile({
url: 'server/upload/url',//upload.PHP script,node.js route,or servlet uplaod url)
data: {myObj: $scope.myModelObj},file: $file
}).then(function(data,status,headers,config) {
// file is uploaded successfully
console.log(data);
});
}
}
OdeToCode posted great service这个东西。所以使用这个简单的指令，你可以轻松地预览，甚至看到进度条：
原文链接：https://www.f2er.com/ajax/160874.html.directive("ngFileSelect",function(){
return {
link: function($scope,el){
el.bind("change",function(e){
$scope.file = (e.srcElement || e.target).files[0];
$scope.getFile();
});
}
}
它在所有现代浏览器中工作！
