I have 2 frames in one page like this ( home.html ) <frameset rows="50%, 50%"> <frame id="treeContent" src="treeContent.html" /> <frame id="treeStatus" src="treeStatus.html" /> </frameset> and then in one frame ( treeStatus.html ) I have something like <body style="margin: 0px"> <div id="statusText">Status bar for Tree</div> </body> I want from the top window to manipulate the div located in the child frame via jquery (e.g show and hide).

Difference between contentDocument and contentWindow javascript iframe/frame access properties

阅读更多关于 Difference between contentDocument and contentWindow javascript iframe/frame access properties

What is the difference between these two properties (contentDocument and contentWindow)? Is there any difference in the way they acces the content in the frame/iframe? Is there any performance issues? Should I use contentXXXXX.document.getElementsBy... or contentXXXXX.getElementsBy... ? I've been searching around in the web but haven't found too much information and before I did a big research I thought I could ask the great community here at stackoverflow. As a comment I'm doing a script that counts inputs on a web page, accessing all levels of frames or iframes and adding those inputs found

Objective-C check if subviews of rotated UIViews intersect?

阅读更多关于 Objective-C check if subviews of rotated UIViews intersect?

I don't know where to start with this one. Obviously CGRectIntersectsRect will not work in this case, and you'll see why. I have a subclass of UIView that has a UIImageView inside it that is placed in the exact center of the UIView: I then rotate the custom UIView to maintain the frame of the inner UIImageView while still being able to perform a CGAffineRotation. The resulting frame looks something like this: I need to prevent users from making these UIImageViews intersect, but I have no idea how to check intersection between the two UIImageViews, since not only do their frames not apply to

问题 I am using ffmpeg to get some jpg from my video at a specific rate (one screenshot every 5 seconds) with this command : ffmpeg -i source -f image2 -r 1/5 %d.jpg This works and give me sequential filenames : 1.jpg 2.jpg 3.jpg 4.jpg What if I need to know at which time those screenshots have been taken ?

Setting unicode characters in java frames

阅读更多关于 Setting unicode characters in java frames

问题 How to display unicode characters (e.g. japanese) in the title of a JFrame in java swing in a Windows XP m/c without the Japanese language pack? It looks like setting the title text to Japanese unicode characters and the font to MS Mincho is not enough. While this is all you need to do to display unicode characters in Swing labels? 回答1: "without the Japanese language pack" ? It seems you have to at least download the language font ... The font is the only thing that needs to be installed on

ios10: viewDidLoad frame width/height not initialized correctly

阅读更多关于 ios10: viewDidLoad frame width/height not initialized correctly

Since upgrading to XCode8 GM and ios10, all of my views created via Interface Builder are not being initialized correctly until much much later than expected. This means in viewDidLoad, cellForRowAtIndexPath, viewWillAppear, etc, the frame size is set to {1000,1000} for every view. At some point they seem to correct, but its far too late. The first problem encountered is with common rounding of corners failing across the board: view.layer.cornerRadius = view.frame.size.width/2 Further problems are showing for anything that relies on frame size to do calculations in the code.
