cocos2d JS function types to each other (string, shape, float, Boolean)

Work busy days, near time to draw some space to share their own learning JS a little note notes to do a bit of record, big God do not spray, thank you!

1. Conversion of strings

1 varFound =false;2Console.log (Found.tostring ());//Output False3 4 varNUM1 = 10;5 varNUM2 = 10.0;6Console.log (Num1.tostring ());//output "Ten"7Console.log (Num2.tostring ());//output "Ten"8 9Console.log (Num2.tostring ());//Output binary form "1010"TenConsole.log (Num2.tostring ());//output octal form "seven" OneConsole.log (Num2.tostring ());//output hexadecimal form "A"

2. Conversion of int of integer type

1 varNUM1 = parseint ("12345red");//back to 123452 varnum2 = parseint ("0xA");//return ten3 varnum3 = parseint ("56.9");//back to4 varNUM4 = parseint ("Red");//returns a value that NaN indicates is not valid for conversion5 varNUM5 = parseint ("10", 2);//returns the binary number 2 (the second argument is the cardinality, which indicates the value of the binary)6 varNUM6 = parseint ("10", 8);//returns octal number 87 varNUM7 = parseint ("10", 10);//returns a decimal number of ten8 varNUM8 = parseint ("AF", 16);//returns the hexadecimal number 175

3. Conversion of floating-point type

1 varnum3 = Parseflost ("12345red");//back to 123452 varnum3 = Parseflost ("0xA");//return NaN3 varnum3 = Parseflost ("11.2");//Back to 11.24 varnum3 = Parseflost ("11.22.33");//back to 11.225 varnum3 = Parseflost ("0102");//back to 1026 varnum3 = Parseflost ("Red");//return NaN

4. Conversion of compulsory type

(1), Boolean (value)----converts the given value to a Boolean type

1     varB1 = Boolean ("");//false-an empty string2     varB2 = Boolean ("Hello");//true-Non-empty string3     varB3 = Boolean (50);//true-not 0 digits4     varB4 = Boolean (NULL);//False-null5     varB5 = Boolean (0);//false-06     varB6 = Boolean ({name: ' Tony '});//true-Object

Note: The Boolean function can convert any type to a Boolean type

(2), number (value)----convert the given value to a tree value

1     varNUM1 = Number (false);//02     varnum2 = Number (true);//13     varnum3 = number (undefined);//NaN4     varNUM4 = Number (NULL);//05     varNUM5 = number ("1.2");//1.26     varNUM6 = Number ("12");// A7     varNUM7 = Number ("1.2.3");//NaN8     varNUM8 = number ({name: ' Tony '});//NaN9     varNUM9 = number (50);// -

Note: The number function can convert any type to a numeric type, null means no value, undefined represents an undeclared variable, or a variable that has been declared but not assigned, or an object that does not exist

(3), string (value)----converts the given value to a string

1     var str1 = String (null);    // "NULL" 2     var str2 = String ({name: ' Tony '});    // "[Object Object]"

Note: The string function can convert any type to a string type
