= {Base: _ withObject,PropertyName: 'foo'}; Function calls in the actual parameters of a catch statement are similar: In this case, the catch object is added to the frontend of the scope, that is, before the active object or global object. However, this particular behavior was identified as a bug in the ECMA-262-3, which was fixed in the new ECMA-262-5. After the fix, in a specific activation object, this points to the global object.

Chapter 5 data-centric-Data Access (3), Chapter 5 Access5.1.3 free operation-serialization and deserialization In Android development, apart from common text and XML files, data is often transmitted or accessed through serialization and deserialization. Android serialization objects can be implemented in two ways: Serializable interface or Parcelable interface. T

no choice. If time passes, you will not have it. Some people may postpone the decision because they cannot make the decision. The delay decision is often the worst. The delay decision is postponed and the time is quietly lost, but you do not have any accumulation on the road, it's a waste of time. This is also called the donkey who starved to death in the licorice room" Chapter 3 how to effectively remem

bug in the ECMA-262-3, which was fixed in the new ECMA-262-5. After the fix, in a specific activation object, this points to the global object. Instead of catch objects.Copy codeThe Code is as follows: try {Throw function (){Alert (this );};} Catch (e ){E (); // _ catchObject-in ES3, global-fixed in ES5}// On ideaVar eReference = {Base: _ catchObject,PropertyName: 'E'};// But, as this is a bug// Then this value is forced to global// Null => globalVar

Rewrite the example summarized in chapter 3 of sharp jQuery The Code is as follows: Script Var x = 10; Var y = 10; $ ("A. tooltip"). mouseover (function (e ){ This. myTitle = this. title; This. title = ""; This. imgTitle = this. myTitle? This. myTitle: "No title "; Var tooltip =" "+ This. imgTitle +" " $ ("Body"). append (tooltip ); $ ("# Tooltip" ).css ({ "Top": + (e. pageY +

Ruby processes single quotes and double quotes differently. (1) double quotation marks can be applied to escape characters (2) strings in double quotation marks can be replaced by # {varname}. For global variables or instance variables, the {} symbol is not required. ------ I don't quite understand the differences between the two variables Nil is also an object in Ruby, but it means nothing. The statement of Ruby's control structure does not have a scratch sign. End indicates the end. T

Section 3 analyzes the SWT Design Principles Returned directory In the first chapter, we have introduced that SWT uses the local control library provided by the underlying operating system. It is only a Java interface for the interaction between the program and the underlying system. The lifecycle of a local control is like a mirror of a Java control object: When a Java Control is created, the local contro

3.2 pairs (pair) and stripes (stripe) A common practice of synchronization in mapreduce programs is to adapt data to the execution framework by building complex keys and values. We have covered this technology in the previous chapter, that is, "package" the total number and count into a composite value (for example, pair) from Mapper to combiner and then to Cer. Based on previous publications (54,94), this section describes two common design patterns

a very important concept in WCF and the most important way to extend it. A contract is a consensus between the server and the client on a certain aspect. It is a bilateral protocol, and the behavior is a way for the client or the server to implement a certain function locally, is a unilateral action. Contract behaviors and operation behaviors are defined as attributes and applied to the operation methods of contract interfaces/classes, contract interfaces, and service types respectively, the en

certain operations, such as an AJAX request. The Peek method can help you control a monitoring property or dependency property without having to create dependencies.In the following example, the dependency property reloads a monitoring property named Currentpagedata with the Ajax method and the other two monitoring property parameters. When pageindex changes, the dependency property is updated, but the change in SelectedItem is ignored because it is controlled by the Peek method. In this case,
