Tstringlist class is a pair of the most factory used in Delphi, we look at the detailed usage of tstringlist here together. Let's start by listing several properties to be discussed:1, CommaText2, Delimiter Delimitedtext3, Names Values Valuefromindex Tstrings is an abstract class that, in actual development, is the most applied except for the basic type. Tstringlist Common Methods and properties: Var List:tstringlist; I:integer; Begin List: = tstringlist.create; List.add (' Strings1 '); Add

Tstrings is an abstract class that, in actual development, is the most applied except for the basic type.General usage We all know, now to discuss some of its advanced usage.Let's start by listing several properties to be discussed:1, CommaText2, Delimiter Delimitedtext3, Names Values ValuefromindexLet's look at the first one: CommaText. How to use it? To speak in code:Constconstr:string = ' aaa,bbb,ccc,ddd ';VarStrs:tstrings;I:integer;BeginSTRs: =

Deferred Helper (3132)When is a helper method for delaying object deferred. var DFD = $. Deferred (); Create a deferred object DFD. Done (); Dfd.fail (); Used: $.when (). done (); $.when (). fail ();The return value of when, is a lingering object.Source: Return Deferred.promise ();As an example: when you can wait for multiple lingering objects to succeed, the trigger succeeds.Example: (1)Success must be successful for more than one. function aaa () {var DFD = $.

the prototype chain of another object.For differences between the two methods, see JavaScript isPrototypeOf vs instanceof usage. Only use prototype chain for inheritance Disadvantages: 1. The prototype property of the reference type value will be shared by the instance; 2. When creating a child-type instance, parameters cannot be passed to the super-Type constructor. functionFather(){this.name ="father";this.friends = ['aaa','bbb'];}functionSon(){}So
