How do I Scroll parent page to top when child page is click within iframe?

阅读更多关于 How do I Scroll parent page to top when child page is click within iframe?

When someone clicks on a link within an iframe (child page), how do I get the parent page to scroll to the top? The issue is the child page will remain in the same spot of the page, because the iframe has a lot of height larger than the parent page. Please note: the parent and child pages are on different sub domains. I created a demo to show this: http://www.apus.edu/_test/iframe/index.htm Evan The trick is to append the following onload="window.parent.parent.scrollTo(0,0)" to the iframe and that should do it! Using JavaScript within the iframe, reference the parent and call the scroll()

Win32 window Owner vs window Parent?

阅读更多关于 Win32 window Owner vs window Parent?

In Win32 programming, what is the difference between a window's parent and a window's owner? I thought I had it figured out, then I came across this code: SetWindowLong(handle, GWL_HWNDPARENT, foo); This actually sets the window's owner, not the parent - despite the GWL_HWNDPARENT being used. Are the terms parent/owner interchangeable, or is there actually a difference? Owner is the Window* responsible for a control or dialog (for example, responsible for creating/destroying the window). Parent is the next-senior window* to a control or dialog in the window chain, but isn't actually

How to create a delphi form containing multiple 'child' forms that can be moved/sized and show activated

阅读更多关于 How to create a delphi form containing multiple 'child' forms that can be moved/sized and show activated

问题 I've created a form that hosts one or more 'child' forms. In my edit mode, each child form shows its border and caption bar allowing it to be moved and sized (a bit like the old MDI app). Out of my edit mode, the borders disappear and the child forms are fixed in position. For my simple demo, I'm creating the child forms thus: procedure TForm1.Button1Click(Sender: TObject); var Frm : TForm; begin Frm := TForm3.Create( Self ); Frm.Parent := Self; Frm.Visible := True; The result is a layout

jQuery select descendants, including the parent

阅读更多关于 jQuery select descendants, including the parent

问题 Consider the following HTML: <div class="foo" id="obj"> I should be changed red <div class="bar" style="color:black;"> I should not be changed red. <div class="foo">I should be changed red.</div> </div> </div> Given a DOM element obj and an expression, how do I go about selecting any children and possibly obj ? I'm looking for something similar to "select descendants" but also including the parent, if it matches the expression. var obj = $("#obj")[0]; //wrong, may include siblings of 'obj' $(

How to override a LESS mixin variable based on a parent's variable

阅读更多关于 How to override a LESS mixin variable based on a parent's variable

I am a newbie, so be gentle. I am sure my terminology is incorrect too: suppose I have my own jumbotron override: .jumbotron { background-color: #ff4400; } and then I want to have a custom override of that where I inherit the above class and only override its background color using its color as a parameter to "lighten()". I can't figure out the syntax: .Myjumbotron { .jumbotron; /* not sure what goes below for "parent.background-color" */ background-color: lighten(parent.background-color, 30%); } Harry LESS allows you to define variables. So you can define a variable for the parent's color and

I have a folder called "April reports" that contains a folder for each day of the month. Each folder then contains another folder which contains PDF files: April reports ├─01-04-2018 │ └─dayreports │ ├─approved.pdf │ └─unapproved.pdf │ ├─02-04-2018 │ └─dayreports │ ├─approved.pdf │ └─unapproved.pdf ╎ ╎ └─30-04-2018 └─dayreports ├─approved.pdf └─unapproved.pdf The PDFs have the same name for each day so the first thing I want to do is move them up one level so that I can use the folder name containing the date to rename each file so that it will contain the date. The script I have tried is this

Forwarding child control MouseMove events to the parent seamlessly

阅读更多关于 Forwarding child control MouseMove events to the parent seamlessly

问题 I have a custom UserControl that I am drawing using the GDI+. It is a transparent control which draws small shapes on top of the parent control. All the parent window does is creates the control, gives it a Rectangle in which to draw itself, and then it receives events if the user clicks on the non-transparent areas. The drawing part works perfectly, but right now what I need to do is to as seamlessly as possible forward all MouseMove, MouseClick, etc. events to the parent control IF those
