Javacript document.write catch


If you're dealing with 3rd party scripts, simply replacing document.write to capture the output and stick it in the right place isn't good enough, since they could change the script and then your site would break.
writeCapture.js does what you need (full disclosure: I'm the author). It basically rewrites the script tags so that each one captures it's own document.write output and puts it in the correct place. The usage (using jQuery) would be something like:
$(document.body).writeCapture().append('<script type="text/javascript" src="http://3rdparty.com/foo.js"></script>');
Here I'm assuming that you want to append to the end of the body. All jQuery selectors and manipulation methods will work with the plugin, so you can inject it anywhere and however you want. It can also be used without jQuery, if that is a problem.

JS ekrano screenshot paėmimas ir siuntimas į serverį

http://permadi.com/2010/10/html5-saving-canvas-image-data-using-php-and-ajax/
http://www.jedox.com/en/screen-shot-web-via-javascript-saving-back-server
https://html2canvas.hertzen.com/
html to canvas alternatyva: http://cburgmer.github.io/rasterizeHTML.js/ taip pat https://github.com/Irrelon/html-to-canvas

function saveViaAJAX()
{
var testCanvas = document.getElementById("testCanvas");
var canvasData = testCanvas.toDataURL("image/png");
var postData = "canvasData="+canvasData;
var debugConsole= document.getElementById("debugConsole");
debugConsole.value=canvasData;

//alert("canvasData ="+canvasData );
var ajax = new XMLHttpRequest();
ajax.open("POST",'testSave.php',true);
ajax.setRequestHeader('Content-Type', 'canvas/upload');
//ajax.setRequestHeader('Content-TypeLength', postData.length);


ajax.onreadystatechange=function()
{
if (ajax.readyState == 4)
{
//alert(ajax.responseText);
// Write out the filename.
document.getElementById("debugFilenameConsole").innerHTML="Saved as<br><a target='_blank' href='"+ajax.responseText+"'>"+ajax.responseText+"</a><br>Reload this page to generate new image or click the filename to open the image file.";
}
}

ajax.send(postData);
}


Tačiau mums reikia html versti į canvas, naudojant html2canvas.js
function takeScreenShot(){
html2canvas(window.parent.document.body, {
onrendered: function(canvas) {
var cand = document.getElementsByTagName('canvas');
if(cand[0] === undefined || cand[0] === null){
}else{
//cand[0].remove();
document.body.removeChild(cand[0]);
}
document.body.appendChild(canvas);
}
});
}




Server side:
<?php
if (isset($GLOBALS["HTTP_RAW_POST_DATA"]))
{
  // Get the data
  $imageData=$GLOBALS['HTTP_RAW_POST_DATA'];
  // Remove the headers (data:,) part.
  // A real application should use them according to needs such as to check image type
  $filteredData=substr($imageData, strpos($imageData, ",")+1);
  // Need to decode before saving since the data we received is already base64 encoded
  $unencodedData=base64_decode($filteredData);
  //echo "unencodedData".$unencodedData;
  // Save file. This example uses a hard coded filename for testing,
  // but a real application can specify filename in POST variable
  $fp = fopen( 'test.png', 'wb' );
  fwrite( $fp, $unencodedData);
  fclose( $fp );
}
?>
