javascript array index problem! -


var a = नया सरणी (); एक [1] = 'ए'; बी [10] = 'बी'; console.log (क); / [अपरिभाषित, "ए", अपरिभाषित, अपरिभाषित, अपरिभाषित, अपरिभाषित, अपरिभाषित, "बी"] / मैं अपरिभाषित तत्व को निकालना चाहता हूं लेकिन प्रक्रिया क्या है ?? < / P>

सबसे पहले, jQuery का इससे कोई लेना-देना नहीं है।

दूसरा, सरणियाँ "ऑटोफ़िल्ल्ड" हैं यदि आप सूचकांक 10 को परिभाषित करते हैं, तो सभी इंडेक्सस 0 - 9 स्वचालित रूप से कब्जा कर लिया जाएगा, बस जावास्क्रिप्ट एरेज़ का काम करने का तरीका।

< P> आप जो खोज रहे हैं वह शायद एक ऑब्जेक्ट है: 

  var a = {}; एक [1] = 'ए'; एक [10] = 'बी';

या 

  var a = {1: 'ए', 10: 'बी'};

Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
