jQuery 和 Canvas.toDataURL
我正在编写一个脚本,其中一小部分涉及获取画布并将其转换为可下载的图像。为此,我这样做:
var thumb_jpeg = thumbnail.toDataURL("image/jpeg");
$("#" + options.dest).attr('src',thumb_jpeg);
...其中缩略图是画布标签,选项.dest 是 img id 的名称。
这段代码在 Chrome 中完美运行,但当我在 Firefox 中尝试时,Firebug 会抛出此错误:
Security error" code: "1000
var thumb_jpeg = thumbnail.toDataURL("image/jpeg");
我会链接到整个脚本,但所有内容都托管在我的计算机上。有谁知道这可能意味着什么?
谢谢! 杰夫
I'm working on a script, and a small part of that involves taking a canvas and converting it to a downloadable image. To do this, I do:
var thumb_jpeg = thumbnail.toDataURL("image/jpeg");
$("#" + options.dest).attr('src',thumb_jpeg);
...where thumbnail is a canvas tag and options.dest is the name of an img id.
This code works perfectly in Chrome, but when I try it in Firefox, Firebug throws up this error:
Security error" code: "1000
var thumb_jpeg = thumbnail.toDataURL("image/jpeg");
I would link to the whole script, but everything is hosted on my computer. Does anyone have any idea what this might mean?
Thanks!
Jeff

我相信这可能是因为您将其托管在您的计算机上。您是直接在本地文件系统上工作还是在 MAMP 或 WAMP 等本地服务器上工作?我之前曾弹出过此安全代码,当我将文件从硬盘驱动器移动到服务器时,问题得到了缓解。
I believe it may be because you have it hosted on your computer. Are you working directly from your local filesystem or are you working on a local server like MAMP or WAMP? I had this security code pop up on me before and it was alleviated when I moved my files from my hard drive on to a server.
朋友,这个方法非常有效:
