javascript - jQuery Find class and store it as a Variable -

-

मेरे पास कुछ & lt; div & gt; है, जिनमें समयरेखा -वर्ष - और फिर जुड़ा वर्ष।

मैं वर्ष के साथ कक्षा को खोजने की कोशिश कर रहा हूं और वर्ष को एक चर में निकालने के लिए div । 

  & lt; div class = "jsn-bootstrap3 टाइमलाइन-ईवेंट टाइमलाइन-वर्ष -2012" & gt; वर्ष और लेफ्टिनेंट; / div & gt; & Lt; div वर्ग = "जेएसएन-बूटस्ट्रैप टाइमलाइन-ईवेंट समयरेखा-वर्ष -2011" & gt; वर्ष और लेफ्टिनेंट; / div & gt;    
 
 
 इसे करने का एक तरीका  text  विधि का उपयोग कर रहा है और थोड़ा नियमित रूप से व्यय: 
 
  $ ('[class * = "time-year-year"])। पाठ (कार्य () {वापसी $ (यह) .text () +' ' + This.className.match (/ समय-वर्ष - (\ d +)? /) [1];});  
 
 डेमो: 
 
 लेकिन अगर आप इस पर गए तो आप अपना कोड क्लीनर बना सकते हैं: 
 
  & lt; div class = "jsn -बूटस्ट्रैप 3 समयरेखा-घटनाएं "डेटा-वर्ष =" 2012 "& gt; वर्ष & lt; / div & gt; & Lt; div वर्ग = "जेएसएन-बूटस्ट्रैप टाइमलाइन-ईवेंट" डेटा-वर्ष = "2011" & gt; वर्ष & lt; / div & gt;  
 
 और फिर: 
 
  $ ('। टाइमलाइन-ईवेंट')। पाठ (फ़ंक्शन () {वापसी $ (यह) .text () + '' + $ (यह) .डेटा ('वर्ष');});  
 
 या इस मामले में सिर्फ सीएसएस के साथ ईवेंट: 
 
  .timeline-events: {content: '' attr (डेटा-वर्ष) के बाद; }  
 
 सीएसएस डेमो:

winforms - C# Form - Property Change -

-
I have a form that has a property named car A class with many properties. The Properties is being displayed on the current car on the basis of some user actions that are being displayed. So I have to know whether the property has been allocated or set to zero. I'm aware of INotifyPropertyChanged , but in my case I'm not sure that since this change I have changed my car properties car do not want to monitor the property. Any idea how to accomplish this? In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
