html，css，从gif文件执行javascript
[英]html, css, execute javascript from a gif file
问题描述
I would like to know if it's possible to execute javascript from embedded .gif file . 
我想知道是否可以从嵌入式.gif文件执行javascript。 I can make rewrite to a php file to seem as a gif file and execute the code from there but I'm not faimilar with css/html therefore I was wondering if there is any trick to make seem there is embedded a picture but to execute javascript . 我可以重写为php文件，看起来像是gif文件，然后从那里执行代码，但是我对css / html不太熟悉，因此我想知道是否有任何技巧可以使似乎嵌入了图片但可以执行javascript。 I tried img src attribute but is not working as the browser seems to consider it just a simple picture... 我尝试了img src属性，但由于浏览器似乎认为它只是一张简单的图片而无法正常工作...

GIF compression is lossy and is not suitable for code. GIF压缩有损，不适合代码。 However, the javascript hacker Jacob Seidelin implemented something very similar using pngs: http://blog.nihilogic.dk/2008/05/compression-using-canvas-and-png.html 但是，JavaScript黑客Jacob Seidelin使用png实现了一些非常相似的东西： http : //blog.nihilogic.dk/2008/05/compression-using-canvas-and-png.html

Not directly answering your question, but you can embed JavaScript into SVG. 您可以直接将JavaScript嵌入SVG，而不必直接回答您的问题。 Although not most browsers support SVG, but most SVG viewers support JavaScript. 虽然不是大多数浏览器都支持SVG，但是大多数SVG查看器都支持JavaScript。
