Pdf download javascript

Portable Document Format is also has many rarely used features. We are all accustomed to the text and images in PDF documents, but this is only a subset of what the format offers. PDF has set of features for creating documents that could change their contents in response to reader actions. One of such features is the ability to use Javascript in PDF documents.

Here is a traditional "Hello World" sample for a start. Please note that I'll use C and Docotic. Pdf library for the samples. You can download source code of all the samples at the end of the article. You should see something like on the following screenshot if you open the PDF created by the sample in Adobe Reader:. PDF supports actions. It is something that is done when an event occurs. For example, clicking on a link in a PDF document outline might trigger an action that cause viewer to open a page in the document:.

There are different types of actions defined. One of the types is Javascript actions. An action of this type can be created using PdfDocument. CreateJavaScriptAction method. The method accepts Javascript code. Then the action can be attached to the OnOpenDocument event. In most situations, this will mean creating a folder-level trusted function. The following code defines such a function that performs only the save operation. This is a full working example, but it could also be used in a larger automation script.

The inputs to this function provide the document object, path and file name. All three are important for creating a generic function for saving a file. For example, inside the folder-level function the keyword "this" may or may not be the current document. The meaning of "this" depends on the calling context, which is unknown.

So it is very important to include the document object, "oDoc," even if the function is meant to be used on the current PDF. If anything goes wrong with the save, such as a bad input parameter, then the "saveAs" function will throw an exception. The user should never see the alert box because the code calling this function should only pass in good parameters. Once created, this folder-level function can be called from anywhere in the Acrobat JavaScript context, including from a script inside a PDF.

They provide important supporting information and examples, especially the Device Independent File Path Format article. UnsupportedValueError: Value is unsupported.

What is the secret to making this work? Thanks for getting back to me. I have created a form in live cycle with a save button that, when clicked, automatically names the. In order for this to work, the code that saves the file needs to be placed in a folder-level JavaScript file. Then, code in the form can generate the file name based on the field values and pass it to the folder-level code. Is there a way for JavaScript to use content from a Field as the file name? Hello, Is it possible to save to the current users profile folder i.

HI all! Just to make sure I read this right. If I create a livecylce form that has javascript in it to populate drop downs or such , if a user has adobe reader prior to XI, the javasscript will not save in the form when they saving it using readed.

You need to learn about programming and JavaScript. Phil Peacock, The problem with Reader Extensions is that they are specific to different versions of Acrobat.
