Is it possible to save a google chart as an image?

由 余生长醉 提交于 2019-12-02 20:55:36
I am making an application in which I would need to save the google chart as an image . All I am using is tomcat, servlets and javascript. Is there a way to save the following generated chart as an image? (refer to code at the end of post). The idea is that user would see this chart and then would have the option of uploading it to his facebook profile. I am not sure if this will be uploadable to facebook in its native format or will be needed to be saved as a jpg. <html> <head> <script type="text/javascript" src="https://www.google.com/jsapi"></script> <script type="text/javascript"> google

How to save HTML5 canvas?

由 十年热恋 提交于 2019-12-02 18:29:05
Currently I am using Canvas2Image to save the content of my HTML5 canvas. It doesn't appear to work in Google Chrome, however. Any ideas on how to work around the issue are welcome. :) canvas.toDataURL() appears to work fine in Chrome, so it may be a library issue. The "convert canvas to image" functionality seems to work, though. use this code <html> <head> <script src="base64.js" type="text/javascript"></script> <script src="canvas2image.js" type="text/javascript"></script> </head> <body> <input type="button" id="savecanvas" value="Save Image" onclick="savecanvasfile()"/> </body> </html>

What's the best way to save a complete webpage on a linux server?

由 故事扮演 提交于 2019-12-02 18:28:29
I need to archive complete pages including any linked images etc. on my linux server. Looking for the best solution. Is there a way to save all assets and then relink them all to work in the same directory? I've thought about using curl, but I'm unsure of how to do all of this. Also, will I maybe need PHP-DOM? Is there a way to use firefox on the server and copy the temp files after the address has been loaded or similar? Any and all input welcome. Edit: It seems as though wget is 'not' going to work as the files need to be rendered. I have firefox installed on the server, is there a way to

Everytime the button is clicked it will added the content that is typed at that moment in the 'database'. The only demand of the saved

Get the html of the javascript-rendered page (after interacting with it)

由 断了今生、忘了曾经 提交于 2019-12-02 17:41:22
I would like to be able to save the state of the html page after I've interacted with it. Say I click a checkbox, or the javascript set the values of various elements. How can I save the "javascript-rendered" page? Thanks. That should do and will grab the ALL page not just the body console.log(document.getElementsByTagName('html')[0].innerHTML); Grant In Chrome (and apparently Firefox), there is a special copy() method that will copy the rendered content to the clipboard. Then you can do whatever you want by pasting it to your preferred text editor. https://developers.google.com/chrome
