如何使用AngularJS获取SVG图像的路径id

Question

我正在尝试使用AngularJS和Jquery找到SVG图像的路径ID，但是下面的代码不起作用。有什么建议吗？

var app = angular.module("myApp", []);
app.controller('uiCtrl', function($scope,$http) {
 $scope.list1 = {img : 'https://dev.w3.org/SVG/tools/svgweb/samples/svg-files/gallardo.svg'};

});


  document.querySelector('object').addEventListener('load',function(){
        var p = this.contentDocument.documentElement.querySelectorAll('path');
        for(i=0;i<p.length;i++){
         p[i].addEventListener('click', function(){ 
              alert("PATH ID"+this.id+"…")
            });
        }
    });

#previewImg{
border : 1px solid;
}

</div>
