Javascript: access to an object's member by name -

-

मेरे पास themesData नामक ऑब्जेक्ट है: 

  var themesData = {} ThemesData.a = {कुंजी: "मान"}; ThemesData.b = {कुंजी: "अन्य मान"};

... और मैं अपने नाम से सदस्यों में से एक का उपयोग करना चाहता हूं। मुझे एक स्ट्रिंग मिलती है जिसमें "a" या "b" होता है और मैं उचित सदस्य का मान प्राप्त करना चाहता हूं।

मुझे उस पर कुछ मदद करने में खुशी होगी।

themesData ["a"]। कुंजी आपकी आवश्यकता है और यह themesData के बराबर है A.key , फिर भी "सरणी अनुक्रमणिका शैली" नोटेशन आपको डायनामिक रूप से सूचकांक नामों को बनाने की अनुमति देता है।
