Sure, a creator of a document can just add date field to the document and stop there. However, it would be nice to assist someone who will fill document later by putting current date to the date field.
In most cases this will be just what is expected. I won't go into details of how to create a date field. Let's focus on the Javascript part only. So, we need to put current date into a date field there is three fields actually, one for day, month and year. Here is the script:.
Using a string for all this code is probably not very convenient because of need to escape quotes. And editing such code later might be painful because of lack of formatting. Let's put a text file with code into application resources and use another overload of CreateJavaScriptAction method.
Please notice that I am using an overload of util. This should be taken into account if you are going to support anything other than Adobe Reader. Another approach is to implement custom code that does the same as util.
Please also notice that code populates a field only if it's empty. Without this additional check a following scenario might occur: a person fills the document, saves it but next time the document is opened all date fields are reset with current date. Suppose you want to ensure that day and year are numbers. It's easy. Let's use following code for this:. This new array of strings will repeat n-times the number of columns in the pdf table.
The repetition will depend on how the pdf was structured, perform pre-inspection of your pdf. What is JavaScript? Editors For JavaScript. How to Start with JavaScript? Display Prompt box using JavaScript.

This answer should be upvoted a lot more, pdfmake is so much more robust than jspdf. However just a side note, it is wrapper around PDFKit library.
From comparing the two playgrounds, to me it seems that jsPDF is more targeted at "graphic" PDF creation, whereas pdfmake is targeted more at generating well-formatted "plain" documents, it seems to have a lot more options for generic text formatting. Is this IE friendly? It works in both Node and the browser, and supports a bunch of stuff that other libraries do not: Embedding subsetted fonts, with support for unicode.
Lots of advanced text layout stuff columns, page breaking, full unicode line breaking, basic rich text, etc. Coming soon: see the fontkit branch if you're interested. More graphics stuff: gradients, etc. Built with modern tools like browserify and streams. Usable both in the browser and node. Isn't this a server side library? I think the discussion is on the client side js library. PDFKit works in both Node and the browser as mentioned in the answer.
See the link to a browser demo. Does this compress images? I am working on a web app that functions similar to camscanner and I am looking for PDF creation through javascript to leverage the compression and multi page format.
I've been using PDFKit recently and although it has a few glitches it does work well and is very solid. I would recommend it. Kpym Kpym 3, 1 1 gold badge 18 18 silver badges 17 17 bronze badges.
