问题 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

问题 is it possible to use Java Reflection to print out the attributes of a parent class. 回答1: Yes, you could do something like this: Class<?> parentClass = getClass().getSuperclass(); Field[] fields = parentClass.getDeclaredFields(); for (Field field : fields) { System.out.println("field: " + field.getName()); } Method[] methods = parentClass.getDeclaredMethods(); for (Method method : methods) { System.out.println("method: " + method.getName()); } 回答2: Given an appropriately permissive security

How to find a parent with a known class in jQuery?

耗尽温柔 提交于 2019-11-26 21:30:55
I have a <div> that has many other <div> s within it, each at a different nesting level. Rather than give every child <div> an identifier, I rather just give the root <div> the identifier. Here’s an example: <div class="a" id="a5"> <div class="b"> <div class="c"> <a class="d"> </a> </div> </div> </div> If I write a function in jQuery to respond to class d and I want to find the ID for its parent, class a , how would I do this? I cannot simply do $('.a').attr('id'); , because there are multiple class a s. I could find its parent’s parent’s parent’s ID but that seems of poor design, slow, and

Parent(), faster alternative?

问题 I am working with a dashboard of divs and each div it has a tree of which the buttons are. Every time I have to know which the id of that div is so I am using parent() alot. Mostly I am doing $(this).parent().parent().parent() to find the ID of div so I can set variables to it. The app is based on the id's of each div. Is it consider slow to use parent() up to 3 times but pretty much on every function? Is there any other alternative? I am looking for something like benchmarks-style which

How to call a parent method from child class in javascript?

问题 I've spent the last couple of hours trying to find a solution to my problem but it seems to be hopeless. Basically I need to know how to call a parent method from a child class. All the stuff that I've tried so far ends up in either not working or over-writing the parent method. I am using the following code to set up OOP in javascript: // SET UP OOP // surrogate constructor (empty function) function surrogateCtor() {} function extend(base, sub) { // copy the prototype from the base to setup

Import from sibling directory

问题 I have a Python class called "ClassA" and another Python class which is supposed to import ClassA which is "ClassB". The directory structure is as follows: MainDir ../Dir ..../DirA/ClassA ..../DirB/ClassB How would I use sys.path so that ClassB can use ClassA? 回答1: You really should be using packages. Then MainDir is placed at a point in the file system on sys.path (e.g. .../site-packages), then you can say in ClassB: from MainDir.Dir.DirA import ClassA # which is actually a module You just

Why does appending a <script> to a dynamically created <iframe> seem to run the script in the parent page?

不打扰是莪最后的温柔 提交于 2019-11-26 16:02:54
I'm attempting to create an <iframe> using JavaScript, then append a <script> element to that <iframe>, which I want to run in the context of the <iframe>d document. Unfortunately, it seems I'm doing something wrong - my JavaScript appears to execute successfully, but the context of the <script> is the parent page, not the <iframe>d document. I also get a 301 Error in Firebug's "Net" tab when the browser requests iframe_test.js , though it then requests it again (not sure why?) successfully. This is the code I'm using (live demo at http://onespot.wsj.com/static/iframe_test.html ): iframe_test

using postmessage to refresh iframe&#39;s parent document

问题 I have a greasemonkey script that opens an iframe containing a form from a different sub-domain as the parent page. I would like to refresh the parent page when the iframe refreshes after the form submission I am at the point where I can execute a function when the iframe refreshes, but I cannot get that function to affect the parent document. I understand this is due to browser security models, and I have been reading up on using postMessage to communicate between the two windows, but I

Make div (height) occupy parent remaining height

若如初见. 提交于 2019-11-26 14:19:19
http://jsfiddle.net/S8g4E/ I have a container div with two children. The first child has a given height. How can I make the second child to occupy the "free space" of the container div without giving a specific height? In the example, the pink div should occupy also the white space. Similar to this question: How to make div occupy remaining height? But I don't want to give position absolute . Expanding the #down child to fill the remaining space of #container can be accomplished in various ways depending on the browser support you wish to achieve and whether or not #up has a defined height.

How do I set the working directory of the parent process?

As the title reveals it, we are writing a Unix-style shell utility U that is supposed to be invoked (in most cases) from bash. How exactly could U change the working directory of bash (or parent in general)? P.S. The shell utility chdir succeeds in doing exactly the same, thus there must be a programmatic way of achieving the effect. Don't do this. FILE *p; char cmd[32]; p = fopen("/tmp/gdb_cmds", "w"); fprintf(p, "call chdir(\"..\")\ndetach\nquit\n"); fclose(p); sprintf(cmd, "gdb -p %d -batch -x /tmp/gdb_cmds", getppid()); system(cmd); It will probably work, though note that Bash's pwd
