How to Generate Image from html using js?

This tutorial is about generating the image from the HTML. You can just create the HTML and put this code after your code, and it will generate the image from your HTML. Below is the easy step to generate the image from custom HTML.

Step 1)

Create one PHP file like index.php as below.

<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Html To Image</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"> </script>
<script src="https://files.codepedia.info/files/uploads/iScripts/html2canvas.js"> </script>
<div class="bingo-box bingo-green generatedata" id="generatedata1" data-id="1">
<div class="number-row number-row1">
<div class="number number1">1</div>
<div class="number number2">2</div>
<div class="number number4">4</div>
<div class="number number5">5</div>
<div class="number number5">9</div>
</div>
</div>
<script>
        $(document).ready(function() {
            var getCanvas;
            $( ".generatedata" ).each(function( index ) {
                var dataid = $( this ).attr("id");
                var catid = $( this ).data("id");
                var datafid = parseInt(index) + parseInt(1);
                var element = $("#"+dataid);
                html2canvas(element, {
                    onrendered: function(canvas) {
                        getCanvas = canvas;
                        var imgageData = getCanvas.toDataURL("image/png");
                        var newData = imgageData.replace(/^data:image\/png/, "data:application/octet-stream");
                        $.ajax({
                          type: "POST",
                          url: "upload.php",
                          data: {
                             imgBase64: newData
                          }
                        }).done(function(o) {
                          console.log('saved');
                        });
                    }
                });
            });
        });
    </script>

Create another page like upload.php

<?php
$catid = $_POST['catid'];
$folderPath = "upload_img/";
$image_parts = explode(";base64,", $_POST['imgBase64']);
$image_type_aux = explode("image/", $image_parts[0]);
$image_type = $image_type_aux[1];
$image_base64 = base64_decode($image_parts[1]);
$filename = uniqid() . '.png';
$file = $folderPath . $filename;
file_put_contents($file, $image_base64);
?>

Step 3)

Now Just run the index.php file in your browser; this will generate the image in the folder.

Can I just say what a relief to discover a person that
genuinely knows what they are talking about
online. You actually understand how to bring a problem to light and make
it important. A lot more people must read this and understand this side of the story.
I can’t believe you aren’t more popular since you certainly have the gift.

I’m impressed, I have to admit. Rarely do I come across a
blog that’s both educative and entertaining, and let
me tell you, you’ve hit the nail on the head. The issue is
an issue that too few men and women are speaking intelligently about.
Now i’m very happy I stumbled across this in my search for something relating to this.
