-
HTML :

<button onclick="pdfdownload()" class="btn btn-success"><i class="fa fa-download" ></i> Download PDf</button>
<div class="table-responsive" id="exportthis">
this is demo text
</div>

Javascript:

<script src="https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.22/pdfmake.min.js"></script>
  <script src="https://cdnjs.cloudflare.com/ajax/libs/html2canvas/0.4.1/html2canvas.min.js"></script>

 <script type="text/javascript">

function pdfdownload ()

 {
html2canvas(document.getElementById('exportthis'), {
            onrendered: function (canvas) {
                var data = canvas.toDataURL();
                var docDefinition = {
                    content: [{
                        image: data,
                        width: 500,
                    }]
                };
                pdfMake.createPdf(docDefinition).download("<?php echo $view_invoice[0]['lease_invioce_ino'];?>.pdf");
            }
        });
}
</script>




Using angular js:
File :script.js
var app = angular.module("app", []);

 app.controller("listController", ["$scope",
   function($scope) {
     $scope.data=  [{"agence":"CTM","secteur":"Safi","statutImp":"operationnel"}];
     
     $scope.export = function(){
        html2canvas(document.getElementById('exportthis'), {
            onrendered: function (canvas) {
                var data = canvas.toDataURL();
                var docDefinition = {
                    content: [{
                        image: data,
                        width: 500,
                    }]
                };
                pdfMake.createPdf(docDefinition).download("test.pdf");
            }
        });
     }
   }
 ]);
