Passing data between frames with Javascript

由 陌路散爱 提交于 2019-12-01 12:34:52
问题 I've setup a simple example at http://ryanmalin.co.uk/frames/ If you press "add" it will paste the form data from the left frame into the right frame. When I change the right frames URL to that of another domain Firebug throws an error and it doesn't work. The error shown is: Error: Permission denied to access property 'document' Is it possible to copy data from one pre-filled form on my domain to a form on another domain using frames/javascript? I believe it is an anti-spam measure built

Disable Cookies Inside A Frame/Iframe

由 允我心安 提交于 2019-12-01 04:32:52
Is there any way to programatically disable cookies being created by a page displayed inside of a frame/iframe? Or to generalise further, is it possible to programatically disable javascript running on such a page? Thanks, DLiKS with iframe sandbox attribute (html5) it will be possible (implemented in chrome) http://dev.w3.org/html5/spec/Overview.html#attr-iframe-sandbox NullUserException already answered what you can do today without browser support The only way you could change that for an external website you have no control over is to retrieve the pages using a server-side script, filter

问题 Im trying to edit existing movie with added effects on top thus I need ability to scan all movie frames, get them as UIImage, apply effect and then either update that frame or write it into new movie.

1、获取 子页面 的 window 对象 在父页面中，存在如下两个对象 window.frames document.iframeElement.contentWindow 可以获取到 子页面 window 对象 // iframe id document.getElementById('menuIframe').contentWindow // iframe name window.frames['menuIframe'].window // iframe index 当前窗体的第几个 iframe window.frames[1].window 既然拿到了 window 对象，那函数和DOM就到手了。 2、子 iframe 获取 父页面 window.parent 对象 window.top对象 // 判断当前页面是否是 iframe 或 顶级页面 window.parent == window window.top == window window.parent 即为当前页面的上一级页面的 window 对象，如果当前页面已是 顶层 页面，则 window.parent 就是自己。 3、小实例 <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <

OpenCV frame capture from AVI

由 百般思念 提交于 2019-11-30 21:44:52
I am working on a project with openCV 2.2. I need to do processing on each frame of an AVI file but when I run my code it only grabs the first frame of the file. The CV_CAP_PROP_POS_FRAMES does not seem to be working. Any ideas why not? CvCapture* capture = cvCaptureFromAVI("test1.avi"); IplImage *img = 0; if (!cvGrabFrame(capture)) { printf("Error: Couldn't open the image file.\n"); return 1; } int numFrames = (int) cvGetCaptureProperty(capture, CV_CAP_PROP_FRAME_COUNT); int posFrame = 1; for(int i =0; i <= numFrames; i++){ cvSetCaptureProperty(capture, CV_CAP_PROP_POS_FRAMES, i); posFrame =

问题 I need to open all frames from Tiff image in WPF into memory and then delete the source. And after that I eventually need to render that image (resized according to window size).

What causes Chrome Timeline Frame to have so much empty white space

由 谁说胖子不能爱 提交于 2019-11-30 04:42:16
Sometimes when I Inspect Element in Google Chrome I find that I have some large frames, but they are filled with white space. Anyone know what often causes such large amounts of empty space? I have seen timers cause issues with extending the frames length but in the example below I am unsure why a frame would be so large. Would love some help minimizing these This is documented here , see the 'About clear or light-gray frames' section. 'Clear frames' in question are described there as Idle time between display refresh cycles. According to this video , clear bar indicates browser waiting for a
