parent

So my list looks something like this: <div="list"> <ul> <li class="page item">Parent 1 <ul> <li class="page item">Child of Parent 1 and Parent of Grandchild <ul> <li class="page item">Grandchild</li> </ul> </li> </ul> </li> </ul> </div> This is through Wordpress' list_wp_pages along with a custom CSS suckerfish-like dropdown CSS code. Nothing can be changed in the unordered list itself, so I need to find a way to add a CSS style to only child pages that are also parents (Child of a Parent 1...). I've been trying to add an arrow icon only to child pages that have child pages of their own. I

This question already has an answer here: Can inner classes access private variables? 5 answers The title already says a lot, but basically what i want to do is the following(Example): I have a class called A, and another class inside a called B, like so: class A { int a; class B { void test() { a = 20; } }; }; As you can see my goal is for class B to have access to class A, as it is a nested class.

I'm trying to write an if statement where if one of the elements has it's display set to "none", I want the parent element to also display "none"... This is the code I'm trying, which doesn't work... /* tried this first */ if($('#prevx a').attr('display') == 'none') { $(this).parent().attr('display','none'); } /* and then this */ if($('#prevxa > a').attr('display') == 'none') { $('#prevxa').attr('display','none'); } The markup looks like this: <ul> <li class="navnext" id="nextxa"> <a id="nextx" href="#"><img src="/images/next.png"/></a> </li> <li class="navprev" id="prevxa"> <a id="prevx" href

This question already has an answer here: Is there a CSS parent selector? 31 answers In the following example: <div class="section"> <div class="row">...</div> <div class="row"> <- bottom margin here needs to be 0 -> <div class="section"> <div class="row">...</div> <div class="row">...</div> </div> </div> </div> .row { margin-bottom:10px; } If div .row is parent of div .section reset bottom margin to 0. I can do this with jquery, but is there a way to do it in css? At the moment there is no way in CSS to select the parent element of another element. However, in CSS4 there is the :has pseudo

In a java program, I create a file with File temp = new File("temp"); temp.createNewFile(); Then for some reason when I write File pDir = temp.getParentFile(); and pDir is null. I actually want to write File pDir = temp.getParentFile().getParentFile(); but that throws a null pointer exception. You need a file with a path for that, try getAbsoluteFile. File pDir = temp.getAbsoluteFile().getParentFile(); You're creating a file called temp, but it has no path, so there will be no parent path. If you want to put the file in the current directory: File temp = new File(System.getProperty("user.dir")

I want to access variables of a form from another form. On clicking a button inside my Main form, I want to set my Main form as Parent, then bring up another form (child form) wherein I will access variables of the Main form. My click handler is as follow: private void btnSystem_Click(object sender, EventArgs e) { Form_EnterPassword EP = new Form_EnterPassword(); EP.Parent = this; //error: Top-level control cannot be added to a control EP.ShowDialog(); } It compiles fine without any error. However, when I run the Main form and click on the System button, it throws me an exception. I do
