如何将html div转换成图像,然后保存为gif或png格式?

时间:2022-12-06 21:21:48

I have tried figuring out a multitude of coded div to image methods on * and across the internet. The codes aren't working for me, because none of methods are exactly what I need and I'm screwing up the code with my modifications to fit what I need.

我尝试过在*和internet上找到大量的编码div到图像方法。代码对我不起作用,因为没有一个方法是我所需要的,我用我的修改把代码搞砸了,以满足我的需要。

Anyway, a few minutes ago I found someone who is actually applying the code to divs that are set up like mine. Please take a look at his/her tool (it's what I am doing just with a few more images):

不管怎样,几分钟前我找到了一个人,他实际上是在用和我一样的代码来创建div。请看看他/她的工具(这是我用更多的图片做的):

http://kpomservices.com/html5canvas/indexsucc.html

http://kpomservices.com/html5canvas/indexsucc.html

and his/her blueprint (source file):

及其蓝图(源文件):

view-source:http://kpomservices.com/html5canvas/indexsucc.html

查看源代码:http://kpomservices.com/html5canvas/indexsucc.html

This is what I did:

这就是我所做的:

  1. I copied the scripts from the source file (found after </body> tag):

    我从源文件中复制了脚本(在标签后):

    <script src="js/html2canvas.js"></script> <script src="js/base64.js"></script> <script src="js/canvas2image.js"></script> <script type="text/javascript" src="js/jquery-1.4.2.min.js"></script>

    < script src = " js / html2canvas。js " > < /脚本> < script src = " js / base64。js " > < /脚本> < script src = " js / canvas2image。js " > < /脚本> <脚本type = " text javascript src=" js / jquery-1.4.2.min.js "> < /脚本>

  2. I pasted it into my header file above the </head>.

    我将它粘贴到上面的头文件中。

  3. I replaced all src="" with complete urls (they aren't hosted on my servers yet, because I'm testing to see if this will even work for me first).
  4. 我用完整的url替换了所有src="" "(它们还没有托管在我的服务器上,因为我正在测试这是否会首先对我起作用)。
  5. I copied the function script from http://kpomservices.com/HTML_to_Canvas.php:

    我从http://kpomservices.com/HTML_to_Canvas.php复制了函数脚本:

    function convert() {
                    dom = document.getElementById('watch');
    
                    // execute the html2canvas script
                    var script,
                    $this = this,
                    options = this.options,
                    runH2c = function(){
                        try {
                            var canvas =     window.html2canvas([ document.getElementById('watch') ], {
                                onrendered: function( canvas ) {
    
                                /*
                                canvas is the actual canvas element,
                                to append it to the page call for example
                                */
                                window.open(canvas.toDataURL());
                                //document.body.appendChild( canvas );
                                }
                            });
                        } catch( e ) {
                            $this.h2cDone = true;
                            log("Error in html2canvas: " + e.message);
                        }
                    };
    
                    if ( window.html2canvas === undefined && script === undefined ) {
                    } else {.
                        // html2canvas already loaded, just run it then
                        runH2c();
                    }
                }
    
  6. I pasted it, as is, between <script></script> tags in the header file.

    我将它粘贴到头文件中的标记之间。

  7. I replaced both (2) instances document.getElementById('watch') with my div id name: document.getElementById('captme').

    我用div id名:document.getElementById('watch')替换了(2)两个实例document.getElementById('captme')。

  8. I copied and pasted the displaybox styling from the source file and pasted it before the </head> in header file (I also tried adding it to the css file only, but that didn't work, either):

    我复制并粘贴了源文件中的displaybox样式,并在头文件中的之前粘贴了它(我还尝试将它添加到css文件中,但这也不起作用):

    <style>
    #displaybox {
    z-index: 10000;
    filter: alpha(opacity=50); /*older IE*/
    filter:progid:DXImageTransform.Microsoft.Alpha(opacity=50); /* IE */
    -moz-opacity: .50; /*older Mozilla*/
    -khtml-opacity: 0.5;   /*older Safari*/
    opacity: 0.5;   /*supported by current Mozivalidate-textlla, Safari, and Opera*/
    background-color:#000000;
    position:fixed; top:0px; left:0px; width:100%; height:100%; color:#FFFFFF; text-align:center; vertical-align:middle;
    }
    </style>
    

8) I copied and pasted just these two lines from the source file (I don't need the other two buttons) into the index file after <?php get_header(); ?>:

8)我在 :

<div id="displaybox" style="display: none;"></div>
<input type="button" value="View As Image" onClick="javascript:return convert();">

9) I copied and pasted this line from the source file into the index file after the <div id="captme">:

9)在

后,我将这一行从源文件复制粘贴到索引文件中:

<canvas id="localcanvas" style="display:none" width=500 height=500></canvas>

10) All that and nothing works. I can click on the button but it renders nothing.

所有的这些都不起作用。我可以点击按钮,但它什么也不显示。

What went wrong? Thanks for any guidance you share!

到底是哪里出了错?谢谢大家的指导!

This is working for me. It renders picture from div solnePuzzle and post to PHP script via ajax post. In PHP script save.php, I base_64 decode and save content via file_put_content to img.

这对我很有效。它从div solnePuzzle呈现图片,并通过ajax post将图片发布到PHP脚本。在PHP脚本中保存。我通过file_put_content解码并将内容保存到img。

html2canvas js

html2canvas js

function capture() {
    $("#solnePuzzle").html2canvas({
        onrendered: function (e) {
            $("#img_val").val(e.toDataURL("image/png"));
            var t = $("#myForm").serializeArray();
            $.ajax({
                url: "save.php",
                type: "POST",
                dataType: "json",
                data: {
                    box: box,
                    form: t
                },
                success: function (e) {
                    alert(e.text)
                }
            })
        }
    })
}

This is working for me. It renders picture from div solnePuzzle and post to PHP script via ajax post. In PHP script save.php, I base_64 decode and save content via file_put_content to img.

这对我很有效。它从div solnePuzzle呈现图片,并通过ajax post将图片发布到PHP脚本。在PHP脚本中保存。我通过file_put_content解码并将内容保存到img。

html2canvas js

html2canvas js

function capture() {
    $("#solnePuzzle").html2canvas({
        onrendered: function (e) {
            $("#img_val").val(e.toDataURL("image/png"));
            var t = $("#myForm").serializeArray();
            $.ajax({
                url: "save.php",
                type: "POST",
                dataType: "json",
                data: {
                    box: box,
                    form: t
                },
                success: function (e) {
                    alert(e.text)
                }
            })
        }
    })
}
