javascript - to apply word wrap for the long dynamic text

I am working on angularjs application with jsPDF API to export the content to the PDF file. I have a issue when the text is long to show in the PDF, when the text is long plete sentence is not shown in the generated PDF as seen in the demo link below. I want to apply word wrap so that all the content is displayed in the PDF file.

Check the online demo here :

Code demo:

 var app = angular.module("app", []);

 app.controller("myController", ["$scope",
   function($scope) {
   
   $scope.export = function() {

       // var pdf = new jsPDF('landscape');
       var pdf = new jsPDF('p','pt','a4');
        var pdfName = 'test.pdf';

        var options = {   pagesplit: true};

        var $divs = $('.myDivClass')                
        var totalDiv = $divs.length -1;     
        var currentRecursion=0;

        function recursiveAddHtmlAndSave(currentRecursion, totalRecursions){
            //Once we have done all the divs save the pdf
            if(currentRecursion==totalRecursions){
                pdf.save(pdfName);
            }else{
                currentRecursion++;
                pdf.addPage();
                pdf.fromHTML($('.myDivClass')[currentRecursion], 15, 20, options, function(){
                    recursiveAddHtmlAndSave(currentRecursion, totalRecursions)
                });
            }
        }

        pdf.fromHTML($('.myDivClass')[currentRecursion], 15, 20, options, function(){
            recursiveAddHtmlAndSave(currentRecursion, totalDiv);
        });
    }
   }
 ]);

I have checked the API, and there is splitTextToSize(..) as shown here Word wrap in generated PDF (using jsPDF)? but confused to apply the same in my existing code, as if you see my js code shown above $scope.export i'm iterating the div's to get the dynamic data and then called pdf.save(pdfName). Can anyone provide the solution, Online demo link is also shared.

PS:I may have text, images,and any other html tags in my div(myDivClass).

is using jspdf necessary, you can use html2pdf, have a look at it – Sagar Commented Nov 14, 2017 at 4:53
Yes I have to use jsPDF fromHTML() method, even addHTML() method of jsPDF has many drawbacks so I cannot use it. I already tried html2PDF and it has got its own drawbacks. Poor quality of PDF pared to the one generated using jsPDF fromHTML() and even html2PDF is not recognizing few css elements. jsPDF fromHTML() is supporting wordwrap using splitTextToSize(..) but I could not able to figure it out how to apply in my existing code..Any inputs? @Sagar Bhattacharya – user7833845 Commented Nov 14, 2017 at 5:11
i will need to check – Sagar Commented Nov 14, 2017 at 5:17
sure, thanks. I found this link stackoverflow./questions/24272058/… . Few answers in the shared link are good but unable to apply the same for my dynamic data shown in the js code above. @Sagar Bhattacharya – user7833845 Commented Nov 14, 2017 at 5:20
hey @user7833845 I posted a solution for you , please implement and test if the solution works for you – Sagar Commented Nov 14, 2017 at 17:23

Well I got a quick workaround for your solution , we can set a width of the page and then the long text gets printed inside the pdf and no content breaks out of the pdf , just update your options in the script.js to this :

var options = {   pagesplit: true,'width': 550}

and this will do the work for you

@Sagar is correct. I just set the width of page dynamicly

var doc = new jsPDF(orientation, 'pt', 'a4', true);// orientation could be 'p' (portrail) or 'l' (landscape)

var a4Width = Number(doc.internal.pageSize.getWidth()); //page width is now based on the orientation

doc.fromHTML($('#yourTarget').html(), 0, 0, {
    pagesplit: true,
    'width': a4Width
});
