how to bypass print dialog box using javascript or JQuery..? - javascript

Normally window.print() is used printing webpage, it trigger print dialog box of browser.
Now my question is how can we bypass this printing dialog box and directly print the web page? is there any way by I could avoid to click on OK button?

Nowdays I believe you could avoid the print dialog from any application by using some cloud printing REST API. So far I only know of PrintNode and Google Cloud Print:
https://www.printnode.com/docs/api/curl/
https://developers.google.com/cloud-print/docs/appInterfaces
Hope this helps.

Is there any way to verify whether a print popup is displaying in Chrome browser using C# Selenium? If JavaScript can be used how to use it?

In C# Selenium, after clicking on a button a print preview popup will appear as in the attached image. In case of failure this will not appear and I will use the page elements to find that the test case is failed.
Now in the success scenario, I need to check whether a print preview popup is appeared or not. If YES i need to click on CANCEL button in that print preview popup and verify the page content which is behind the popup. Unfortunately Selenium doesn't identifies the content behind the popup until the popup appears..
Can anyone help me out to solve this problem in C# Selenium.

How can I programmatically save HTML/CSS as a PDF using javascript/jquery?

I'm using OS X and I see on chrome that I can Save as PDF in the print window if I set the destination to "Save as PDF". Does this functionality exist in Windows?
Is there any way I can take advantage of this and have it save to PDF with just a click of a button? How can I open up the print page and save that as a PDF? Can I set the default destination to "Save as PDF" and then programmatically click the "Save" button?
Edit: I have tried to use jsPDF but was unable to pull the CSS.
there is also an option to print PDF on Windows 10.
This javascript code opens a print dialog:
window.print();
I have used PhantomJS before to render PDFs from webpages programmatically. You'd have to write a PhantomJS script to accomplish that but they have helpful examples documented.
jsPDF is a good tool for this.
This question is a possible duplicate of Download a div in a HTML page as pdf using javascript, which provides a demo and sample usage for jsPDF.

Password protect a generated PDF from page

I'm currently using PHP for retrieving data and the JavaScript print function for my inventory reports and my staff saves it in pdf form. This is the sample output:
Everything works perfectly but I have a security issue. I want my staff to not be able to open the pdf, thus securing it with a password.
Is there, by any chance, a way to do this? Like whenever they click a button, instead of the print dialog box (ctrl+ P) opening, it will directly open a save to dialog box and it will automatically have a password so that I can be the only one who can view and print it.
Or is there a PDF library for this?
Any help would be much appreciated.
Found a library and it works as expected.

Explaining
am click print button in HTML page: Yes you will have to click on print button to request the browser to perform an action
next automatically open google chrome print window: Of course, it will be opened as printer/page settings will be asked even in ms word same thing happens while printing it asks for preferred printer & page
and again click print button: Finally you will be asked to submit your confirmation
Understand the whole process & please being on SO don't make a wish
you need to develop desktop based application that connect your web to your computer..
so your web cant request directly to your desktop program instead via browser...
you can use java applets to do that...

How do I put a link to a webpage in a JScript Alert dialog box?

I would like to put a link to a webpage in an alert dialog box so that I can give a more detailed description of how to fix the error that makes the dialog box get created.
How can I make the dialog box show something like this:
There was an error. Go to this page to fix it.
wwww.TheWebPageToFix.com
Thanks.
You can't. Alert boxes don't support html. You should display the error as part of the page, it's nicer than JS alerts anyway.
You can't - but here are some options:
window.open() - make your own dialog
Use prompt() and instruct the user to copy the url
Use JavaScript to just navigate them to the url directly (maybe after using confirm() to ask them)
Include a div on your page with a [FIX IT] button and unhide it
Use JavaScript to put a fix it URL into the user's clipboard (not recommended)
If you really wanted to, you could override the default behavior of the alert() function. Not saying you should do this.
Here's an example that uses the YUI library, but you don't have to use YUI to do it:
YUI-based alert box - replace your ugly JavaScript alert box
You could try asking them if they wish to visit via window.prompt:
if(window.prompt('Do you wish to visit the following website?','http://www.google.ca'))
location.href='http://www.google.ca/';
Also, Internet Explorer supports modal dialogs so you could try showing one of those:
if (window.showModalDialog)
window.showModalDialog("mypage.html","popup","dialogWidth:255px;dialogHeight:250px");
else
window.open("mypage.html","name","height=255,width=250,toolbar=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no,modal=yes");
Or use window.open and put the link there.
Even if you could, alert() boxes are generally modal - so any page opened from one would have to open in a new window. Annoying!
alert("There was an error. Got to this page to fix it.\nwww.TheWebPageToFix.com");
That's the best you can do from a JavaScript alert(). Your alternative option is to try and open a new tiny window that looks like a dialog. With IE you can open it modal.
