.load（）在ipad上不起作用 [英] .load() does not work on ipad

问题描述

我有简单的脚本来检查图像，但它在我的ipad 5.1上无法正常工作。在图像中我收到jpg的流，因此加载必须在每个帧上工作（如在大型野生动物园中），但在ipad中它只会触发一次。可能有些建议吗？

I have simple script to check image, but it is not working properly on my ipad with ios 5.1. In image i receive stream of jpg's, so load must work on each frame (as in big safari), but in ipad it fires only once. May be some suggestions?

$('#image').load(function(){
    console.log(new Date().getTime(););
});

与图像一起使用时加载事件的注意事项

Caveats of the load event when used with images

开发人员尝试的常见挑战解决使用 .load（）的快捷方式是在图像（或
图像集合）完全加载时执行一个函数。有几个已知的警告，其中
应该注意这一点。这些是：

A common challenge developers attempt to solve using the .load() shortcut is to execute a function when an image (or collection of images) have completely loaded. There are several known caveats with this that should be noted. These are:

• 它不能一致地工作也不能可靠地跨浏览器


• 它没有'如果图像src设置为与之前相同的src，则在WebKit中正确触发


• 它没有正确地冒泡DOM树


• 可以停止为已经存在于浏览器缓存中的图像触发

• It doesn't work consistently nor reliably cross-browser
• It doesn't fire correctly in WebKit if the image src is set to the same src as before
• It doesn't correctly bubble up the DOM tree
• Can cease to fire for images that already live in the browser's cache
