I really would love to do this so they can share their results with others. I don't want them to "copy" the results because they can easily change that. If they change what it says in the image, oh well. This will open a new tab or window with the 'screenshot', allowing the user to save it. There is no way to invoke a 'save as' dialog of sorts, so this is the best you can do in my opinion.
This is an expansion of Dathan's answerusing html2canvas and FileSaver. This code block waits for the button with the id btnSave to be clicked. When it is, it converts the widget div to a canvas element and then uses the saveAs FileSaver interface via FileSaver. An example of this working is available at this fiddle. I wrote a universal function to get a screenshot. Keep in mind console. If you wish to have "Save as" dialog, just pass image into php script, which adds appropriate headers.
You can't take a screen-shot: it would be an irresponsible security risk to let you do so.
However, you can:. Take a look at htmlshot packagethen, check deeply the client side section:. It will then create a screenshot of just that div. There is more examples here solving how to capture HTML elements. For full disclosure I am the API creator. It's to simple you can use this code for capture the screenshot of particular area you have to define the div id in html2canvas.
As far as I know you can't do that, I may be wrong. However I'd do this with php, generate a JPEG using php standard functions and then display the image, should not be a very hard job, however depends on how flashy the contents of the DIV are.
What you can do for every result create a screenshot, save it somewhere and point the user when clicked on save result.
This canvas can then be saved as a regular image file. Note the commented section for Safari. A bit later I found an universal solution that works in both Firefox and Safari:. Full source code and a live demo are available in this repository. First of all, even before getting to canvas, custom fonts are not picked up in some browsers.
So, I can conclude that creating a screenshot canvas of a web-page is not reliable or cross-browser enough at the moment. Sadly, this functionality is not available from the page JS. Declaration of VAR and some other stuff. How'd you manage that one? Zuck: People just submitted it. Zuck: I don't know why. Zuck: They "trust me" Zuck: Dumb fucks.
We will also learn about file handling using php.
Take webpage screenshot using HTML5 and jQuery
In this php file we will write script to receive a post request and once we receive a post request we will do file handling to store screenshot data to a json file name data. So, in the above php script what we are doing is we are checking post request.
So if there is a post request then check if data. Now we will create a screenshot. To do this we will write a simple jquery function to read the json file and retrieve the screenshot. Above we wrote a simple jquery function to read the json file and appended the all the screenshots in div element which we targeted using the class name.

Decided today to make an implementation of it into sending feedbacks like you described. The script allows you to create feedback forms which include a screenshot, created on the client's browser, along with the form. It does not require any rendering from the serveras the whole image is created on the client's browser.
I really would love to do this so they can share their results with others. If they change what it says in the image, oh well. This code block waits for the button with the id btnSave to be clicked.

I managed to detect tab switching, and also browser switching through window. Questions: I try to make a horizontal scrolling inside a div. Scrolling happens as the user scrolls the page. Somehow I manage to scroll the div, but it does not look pleasant. Questions: I have defined a data template with the components which are retrieving user input data and then I am downloading it in form of a text file.The script allows you to take "screenshots" of webpages or parts of it, directly on the users browser.
The library should work fine on the following browsers with Promise polyfill :. As each CSS property needs to be manually built to be supported, there are a number of properties that are not yet supported.
It does not require any rendering from the serveras the whole image is created on the clients browser. However, as it is heavily dependent on the browser, this library is not suitable to be used in nodejs. It doesn't magically circumvent any browser content policy restrictions either, so rendering cross-origin content will require a proxy to get the content to the same origin.
As previously mentioned, in order to create a screenshot of an element of your DOM, we'll use the html2canvas library.
You can download this library with NPM using the following command:.
Therefore if you want to create a screenshot of your entire website, you need to pass the body element of your document as first argument of the html2canvas function. As it returns a Promise, you need to add the then function that will be executed once the exportation is ready. In this example, the screenshot will be generated in png format and it will be shown in a new window once it's ready:.
You may need to add the download screenshot feature to your app. For this you will need the FileSaver plugin in your document, read more about this plugin in the official Github repository here. The FileSaver plugin will allow you to generate a download from a Blob directly in the browser. To download the generated screenshot there are 2 options:. With HTML5, the canvas introduced the new method canvas. The method however is not available in all browsers, but there's a Polyfill in case you decide to use it in this way.
If you don't want to mess with a lot of polyfills in case your app needs to provide support for outdated browsers, convert directly the base64 image to a Blob and then save it with FileSaver you will need to mess up with more code though.
Once this is done it is easy to capture a HTML element. You just need to pass the CSS selector of the element you wish to capture to the target parameter. To do this look at the source of the target webpage. An example of which is shown below.
This will contain all of the contents of the features div and nothing else. Often you want to capture page content after the user has interacted with it in some way, for instance after filling out a form. GrabzIt enables you to do this by providing the ConvertPage method. This method must be called on a web page accessible on the internet.
The example creates a copy of the source of a webpage updates it with any form values and passes it to GrabzIt to be converted. As we only want to capture the div divSectionas shown above we are passing that as a target.
However you could not specify the JSON parameters and capture the whole webpage as it has been updated by the user.
Depending on the nature of the website you are capturing you may also use this approach to capture content that is behind a login.
