javascript - jQuery plugin template -


I'm getting this template to build a jQuery plugin

but I do not understand the code, Why declare the plugin as a method of jQuery object, and then we declare the plugin as a method of object $ .fn, why did we do this?

Adding the plugin to $ enables you to write: 

  var $ el = $ ("myselector"); $ .myplugin ($ el, {something: "options", second: "one"});

Writing the plugin in $ .fn enables you to write: 

  $ (".myselector"). Myplugin ({some: "options", second: "one"});

नक्शा = नया बफर्ड इमेज [चौड़ाई] [ऊंचाई]; के लिए (int i = 0; i & lt; height; i ++) {for (int j = 0; j & lt; चौड़ाई; j ++) {if (charMap [j] [i] == पर्वत। इंडेंटफार्म) {if (j + 1 & lt ; चौड़ाई और amp; amp; j-1 & gt; = 0) {if (charMap [j-1] [i]! = पर्वत। इंडेंटिफ़ायर & amp; amp; & amp; amp; charMap [j + 1] [i]! = पर्वत। इंडेंटफार्म) {नक्शा [जे] [आई] = टाइल ग्रिड [1] [10]; }} और {नक्शा [जे] [आई] = टाइल ग्रिड [8] [10]; }}} यह कोड है जिसे मैं सेल के चारों ओर प्रत्येक टाइल को चेक करके 2 डी सर की जांच करने के लिए उपयोग कर रहा हूं लेकिन मुझे लगता है कि किसी को भी सोच रहा हूँ मदद कर सकता है? मुझे संदेह है कि आपको NullPointerException को charMap [j] से प्राप्त हो रहा है [ I] == पर्वत। इंडेंटिफ़ायर लाइन। सुनिश्चित करें कि आप ज्योफ द्वारा सुझाए गए दोनों मानचित्रों के लिए आंतरिक सरणियों को प्रारंभ करते हैं।

python - Assemble mpeg file unable to play in mediaplayer -

I am currently working on a school project and I think that is to gather some problems with the MPEG file I The scope of my project is: 1) Split the MPEG file into pieces of many fixed sizes. 2) Collecting some of them and leaving some part.

asp.net - MVC [HandleError] HandleErrorAttribute called twice when using global logging -

In an MVC3 web application, I was using Public Static Zero Global Filter Filter (GlobalFilterCollection filter) In order to implement global error handling, where the user was shown 'Error' view, if there was no exception, an exception occurred. For a particular view, I also wanted to display a different error view, if by decorating the method with [HandleError (View = "SpecialError")] Unwanted exceptions occurred. It works fine. Then I want to add global logging to unsociable exceptions. I created a custom handle error feature with the logging code: Public class MyHandleErrorAttribute: HandleErrorAttribute {The public override zero over exponence (exception context context) {// code to log code code. Xxation (reference); }} And instead of using this attribute name, register global filter and method decoration has been updated. It usually works, but when there is an exception method that is decorated with MyHandleError (see = "special error...
