example, we want to develop a plugin, make a special edit box, when it is clicked, then alert the contents of the current edit box. You can do this:$.fn.extend ({alertwhileclick:function () {$ (this). Click (function () { Alert (This). Val ()); }); } });$ ("#input1"). Alertwhileclick (); On the page is:$ ("#input1") is a jquery instance, and when it calls the Member method Alertwhileclick, it implements the extension, which pops up the contents of the current edit each time it is clicked.jque

To change the scope of a variable within a function, you can use the global statement.

Lambda Basics
Not lambda?
Lambda broken?
A lambda function is also called an anonymous function. That is, the function has no specific name. Let's take a look at the simplest example:

2. Read files
3. Write files
In python, file operations can be implemented through open functions, which is indeed similar to fopen in C. Obtain a file object through the open function, and then call the read (), write () and other methods to read and write the object.
1. Open
After opening a file using open, remember to call the close () method of the file object. For example, you can use the try/finally statement to ensure that the file can be closed
