在angularjs中使用$ dirty以便在编辑表单时进行检查

我试图通过写一些字段来检查我的表单是否正在编辑.我读过$ dirty应该为这个任务工作,但我无法弄清楚我在这里缺少什么:

<!DOCTYPE html>
<html lang="en">
<script src= "http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
<body>

<div ng-app="myApp" ng-controller="formCtrl">
  <form name = "myForm" novalidate>
    First Name:<br>
    <input type="text" ng-model="user.firstName"><br>
    Last Name:<br>
    <input type="text" ng-model="user.lastName">
    <br><br>
    <button ng-click="reset()">RESET</button>
  </form>
  <p> is Form dirty? {{isDirty}}<p>
  <p>form = {{user }}</p>
  <p>master = {{master}}</p>
</div>

<script>
var app = angular.module('myApp', []);
app.controller('formCtrl', function($scope) {
    $scope.master = {firstName:"John", lastName:"Doe"};
    $scope.reset = function() {
        $scope.user = angular.copy($scope.master);
    };
    $scope.reset();
    $scope.isDirty = $scope.myForm.$dirty;
});
</script>

</body>
</html>

我试图在用户修改表单时将标志isDirty设为true.谢谢

使用angularjs在浏览器的新窗口中打开PDF

我是角度js的新手,我希望在按下按钮后在浏览器的新窗口中打开PDF文档.

我$http.get()在前端发出GET请求,在后端有一个Java休息服务,它响应GET并生成PDF.我希望在浏览器上打开这个PDF.

如果无法以这种方式打开PDF,那么至少用AngularJs打开任何PDF,我该怎么做？

@GET
@Path("/printPdf")
public Response printService(){

//generates the pdf

File reportFile = new File(filePath);
String name = reportName + "." + "pdf";
ResponseBuilder response = Response.ok(new     TemporaryFileInputStream(reportFile));
response.header("Content-Disposition", "attachment; filename=" + name);
response.header("Content-Type", "application/pdf");
response.header("Access-Control-Expose-Headers", "x-filename");
response.header("x-filename", name);

return response.build();
}

这就是后端在休息服务中生成响应的内容.
