javascript - Exclusive selecting list elements -

-

मेरे पास एक अनोर्ड सूची है: 

  & lt; ul & gt; & Lt; li एनजी-क्लास = "{'सक्रिय': चयनित}" एनजी-क्लिक = "चयनित =! सिल्क्टेड" & gt; स्टफ़ 1 & lt; / li & gt; & Lt; li ng-class = "{'सक्रिय': चयनित}" एनजी-क्लिक = "चयनित =! सिल्क्टेड" & gt; स्टफ 2 & lt; / li & gt; & Lt; li एनजी-क्लास = "{'सक्रिय': चयनित}" एनजी-क्लिक = "चुने गए =! सिल्क्टेड" & gt; स्टफ़ 3 & lt; / li & gt; & Lt; / ul & gt;

मैं एक सूची आइटम को उपयोगकर्ता को चुनने के लिए एक क्लास को लागू करना चाहता हूं। केवल एक आइटम उस समय एक ही वर्ग हो सकता है इस दृष्टिकोण के लिए सबसे अच्छा कोणीय-इश तरीका क्या है? लगभग एक दर्जन तत्व हैं या तो, मैं प्रत्येक आइटम के लिए एक नया चर घोषित नहीं करना चाहता हूं।

< P> प्रत्येक आइटम के लिए एक संपत्ति सेट करें: 

  & lt; ul & gt; & Lt; li ng-class = "{'सक्रिय': चयनित == 1}" एनजी-क्लिक = "चयनित = 1" & gt; सामग्री 1 & lt; / li & gt; & Lt; li ng- वर्ग = "{'सक्रिय': चयनित == 2}" एनजी-क्लिक = "चयनित = 2" & gt; सामग्री 2 & lt; / li & gt; & Lt; li ng-class = "{'सक्रिय': चयनित == 3}" एनजी-क्लिक = "चयनित = 3" & gt; सामग्री 3 & lt; / li & gt; & Lt; / ul & gt;

python - Strange behavior using PyQt4's 'pyqtSlot' decorator before another decorator -

-
I have a strange problem with using the QtCore.pyqtSlot decorator in front of the function decorated with a different decorator. The problem below shows this problem, it immediately provides a low QT program with a single button. When pressing a button, the following happens: (1) The signal 'signal_A' and 'signal_B' sequence are connected to method_A and method_B ​​respectively. (2) signal_A and signal_B signals are emitted. (3) The required behavior is that the method_A and method_B ​​are executed. However, it turns out that both signal_A and signal_B trigger method_A, or method_B ​​(oddly, this is nondeterministic, and different for each part of the program!). It appears to be a bug. This issue is present when PyQt4 binding is used in Qt. It is not present when using PySide (use the '-pyside' parameter to verify) I have seen both problems in Python 2 and 3, and both in Windows and Linux This issue is related to the insertion of a decorator be...

c# - UnhandledExceptionMode.ThrowException for AppDomain.UnhandledException -

-
I want to set unhandledExceptionMode.ThrowException for current AppDomain and not only for application threads. An exception from the second thread should also be handled by my current Donan_Unimated exception handler. Is it possible? Here's my code: Fixed class program {/// & lt; Summary & gt; Main entry point for the application /// & lt; / Summary & gt; [STAThread] static zero major () {applications Set unhandled exception mode (unwanted exception. Throws up); AppDomain.CurrentDomain.UnhandledException + = New UnrestrictedExceptionEndception (CurrentDomain_UnhandledException); Application.EnableVisualStyles (); Application.SetCompatibleTextRenderingDefault (wrong); Application.Run (New Form 1 ()); } Static Zero CurrentDomain_UnhandledException (Object Sender, UnhandledExceptionEventArgs E) {File.AppendAllText ("Log.txt", (Exception) e.ExceptionObject). Message + environment. Newline); }} Maybe you search for the behavior provided by Applic...

I'm trying to kill a process using a CMD command line from my C # application, but when I start the application does not happen anything. .. When I try to kill with a command prompt, I get the message: "Access denied" I tried to run as my app administrator and the process was killed. How can I not always use "Run as administrator"? Code: System.Diagnostics.Process process = new System.Diagnostics.Process (); System.Diagnostics.ProcessStartInfo startInfo = New system. Diagnostics.
