javascript - Scaling text to fit in Famo.us Surface -

-

यहाँ सतह है 

  this.gymNameSurface = नई सतह ({size: [true, जिम [1] "", " ''), संपत्तियों: {पृष्ठभूमि का रंग: 'काला', फ़ॉन्टआकार: "2em", लाइनहाइट: '72 पीएक्स'}})   
 ऐसे मामलों में जिम का नाम एक निश्चित # के अंतर्गत है वर्ण, '2em' सही आकार है उदाहरणों में जब जिम का नाम एक निश्चित # वर्णों के ऊपर है, तो यह बहुत बड़ा है।  
 मैं सतह के अंदर पाठ के फ़ॉन्ट आकार को गतिशील रूप से कैसे बदलूं, कहना है, मुझे सतह की चौड़ाई होना & gt; window.innerWidth / 2?  
 धन्यवाद   
 
 
 आप इसे सादे जेएस के साथ कर सकते हैं :  
  var fontsize = "2em"; // कम टेक्स्ट - बड़ा फ़ॉन्ट अगर (this.options.data.gymName.properties.gymName.length & gt; 32) {fontsize = "1.4em"; // अधिक टेक्स्ट - छोटे फ़ॉन्ट आकार}   
 फिर आपकी सतह के गुणों पर:  
  गुण: {... fontSize: fontsize, ...}

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
