What are the properties and methods of regular expressions in Flex programming
This article mainly introduces the attributes and methods of regular expressions in Flex programming. It is very detailed and has a certain reference value. Friends who are interested must read it!
Flex programming-- regular expression
The RegExp class allows the use of regular expressions (that is, patterns that can be used to search for and replace text in strings).
You can create a new RegExp object by using the newRegExp () constructor or by assigning RegExp text to a variable:
Varpattern1:RegExp=newRegExp ("test-\\ d", "I")
Varpattern2:RegExp=/test-\ dplani
Common attributes of regular expressions in Flex programming
Attribute definition party
Constructor:Object
A reference to the constructor of a class object or a given object instance. Object
Dotall:Boolean
◆ specifies the dot character (.) in the regular expression pattern. Whether it matches the newline character. RegExp
Extended:Boolean
◆ specifies whether to use extended mode for regular expressions. RegExp
Global:Boolean
◆ specifies whether global matching is used for regular expressions. RegExp
IgnoreCase:Boolean
◆ specifies whether the regular expression ignores case. RegExp
LastIndex:Number
Specifies the index position in the string to start the next search. RegExp
Multiline:Boolean
◆ specifies whether the m (multiline) flag is set. RegExp
Prototype:Object
◆ 's reference to the prototype object of a class or function object. Object
Source:String
◆ specifies the pattern portion of the regular expression. RegExp
Common methods of regular expressions in Flex programming
Method definition square
◆ RegExp (re:String,flags:String)
Allows you to use two strings to construct regular expressions. RegExp
◆ exec (str:String): Object
Performs a regular expression search in the given string str. RegExp
◆ hasOwnProperty (name:String): Boolean
Indicates whether the specified property has been defined for the object. Object
◆ isPrototypeOf (theClass:Object): Boolean
Indicates whether an instance of the Object class is in the prototype chain of the object specified as a parameter. Object
◆ propertyIsEnumerable (name:String): Boolean
Indicates whether the specified property exists and can be enumerated. Object
◆ setPropertyIsEnumerable (name:String,isEnum:Boolean=true): void
Sets the availability of the dynamic properties of the loop operation. Object
◆ test (str:String): Boolean
Tests whether the regular expression matches in the given string str. RegExp
