Copy Code code as follows:
/* Array */
Array.reverse ()///array reverse sort, into a new array.
Array.Sort ()///Sort the array into a new array by character.
S=array.push ("str1", "str2")//Add array from back, s to add record
S=array.pop ()//delete array from the back, s for deleted records
S=array.shift ()//remove array from front, s for deleted records
S=array.unshift ("str1", "str2")//Add array from front, s to add record
S=array.splice (3,2, "AA", "BB")//starts with the third of the array, deletes two arrays backwards, and adds a new array at that location. s to add a record
S=array.slice (2,4)//starts from the second after the array, takes the fourth, and the array itself does not change.
S=ar1.concat (AR2)//Add the array Ar2 to the array Ar1, generating the new array S.
S=array.join ("#")//The array element is concatenated with a #, forming a string and returning to S.
/* Function/*
Sample:function Test (ARG1,ARG2)
Use:test ("ddd", "SSS", "FFF")
Test.arity://function set number of parameters (return value).
Test.length://function set number of parameters (return value).
Test.caller://Call function for Test () (return function, IE support).
Test.apply (obj, [Arg1, arg2])//makes the specified object (obj) have properties and methods of test.
Test.call (obj, arg1, arg2)//makes the specified object (obj) have properties and methods of test.
Arguments://Actual number of arguments passed in (array returned).
Arguments.callee://currently executing function (return function).
(new Test). Constructor://View the construction (return function) of the new instance (test ()).
/* String */
Str.slice (3,-5)//starts at the end of the third string and takes the first 5 (bottom fifth). Parameter two needs to be greater than parameter one, or negative.
Str.substring (3,6)//starts after the third string and takes the 6th one.
STR.SUBSTR (3,6)//starts after the third string and takes 6 characters backwards.
Str.charcodeat (4)//Returns the 10 encoding of the 5th string.
Str.charat (4)//returns a 5th string.
Str.tolowercase ()//all converted to lowercase characters.
Str.touppercase ()//all converted to uppercase characters.
Str.split (",")//Use "," splits the string and returns an array.
Str.search ("AAA")//Find the position of AAA in the string, commonly used with regular expressions.
Str.indexof ("AAA")//Find the position of AAA in the string.
Str.lastindexof ("AAA")//begins by looking for the position where "AAA" appears in the string.
Str.match ("AAA")//"AAA" removed from STR, returns null or array, and is used in conjunction with regular expressions.
Str.replace ("AAA", "BBB")//Replace the first "triple" with "BBB" and use it in conjunction with regular expressions.
String.fromCharCode (39080)//Returns the character generated by a 10-encoded encoding.
Str1=str2.concat (STR3)//Add STR3 to str2 to generate a new string str1.
