javascript - XMLHttpRequest doesn't work asynchronously -

-

यह मेरा JS 

  var req = new XMLHttpRequest (); req.open ( 'पोस्ट', '/ कुछ-स्थान', true); Req.send ("सर्वर-पक्ष संसाधित करने के लिए एक स्ट्रिंग"); Var resp = req.responseText;

समस्या यह है कि यह काम नहीं करती। जब भी मैं प्रतिक्रिया देखने के लिए console.log (resp) का उपयोग करता हूं, यह एक खाली स्ट्रिंग है।

लेकिन जब मैं दूसरी पंक्ति को req.open ('POST', '/ some-location', गलत) में परिवर्तित कर देता हूं; , resp संसाधित परिणाम मैं async को झूठे में सेट नहीं करना चाहता, हालांकि।

क्या मुझे यह देखकर एक योजना जावास्क्रिप्ट है कि मैं क्या गलत कर रहा हूं?

यह काम नहीं करता क्योंकि यह एक AJAX अनुरोध नहीं है आपको AJAX का उपयोग करना चाहिए यह बहुत जटिल नहीं है और आप

पर निर्देश पा सकते हैं।

c# - How to know the number of Threads created and limit the Tasks accordingly -

-
It is very clear that with task as async / await Instead of calling the asynchronous call threads , my question is: Is there a way to monitor threads while completing these tasks? This is because I can decide an optimal number of times for the thread that the thread does not eat too many CPU cycles at the same time (the CPU is intensive to handle the work). We take an example below (output is also mentioned) Although the program is completed in 5 seconds, but it has two threads (id = 1,4 ) if I increase the number of 6 instead of 2, then it creates 4 threads I know that this is the CLR thread OS thread (which is 4 in my machine Are), but I would like to know how they are mapped O (with actions) and use the same CPU. Is there any way to get it? Test code Fixed zero main (string [] args) {RunTasksWithDelays (). ); } Static async Task Run Task with Dislay () {Stopwatch S = Stopwatch. Startup (); Console.light line ("thread id =" + thread.content.trade.manag...
