Methods Details

decodeURI(encodedURI)

Decodes a URI previously encoded with encodeURI or another similar routine.

Parameters String encodedURI ;

Returns String

Sample

var str = "http://www.mysite.com/my code.asp?name=[cool]";
var encoded = encodeURI(str);
var decoded = decodeURI(encoded);
application.output(encoded);//http://www.mysite.com/my%20code.asp?name=%5bcool%5d
application.output(decoded);//http://www.mysite.com/my code.asp?name=[cool]

decodeURIComponent(encodedURI)

Decodes a URI component previously created by encodeURIComponent or by a similar routine.

Parameters String encodedURI ;

Returns String

Sample

var str = "my code.asp?name=[cool]";
var encoded = encodeURIComponent(str);
var decoded = decodeURIComponent(encoded);
application.output(encoded); //my%20code.asp%3fname%3d%5bcool%5d
application.output(decoded); //my code.asp?name=[cool]

encodeURI(URI)

Encodes a URI by replacing certain characters with escape sequences.

Parameters String URI ;

Returns String

Sample

var str = "http://www.mysite.com/my code.asp?name=[cool]";
var encoded = encodeURI(str);
var decoded = decodeURI(encoded);
application.output(encoded);//http://www.mysite.com/my%20code.asp?name=%5bcool%5d
application.output(decoded);//http://www.mysite.com/my code.asp?name=[cool]

encodeURIComponent(URI)

Encodes a URI component by replacing all special characters with their corresponding UTF-8 escape sequences.

Parameters String URI ;

Returns String

Sample

var str = "my code.asp?name=[cool]";
var encoded = encodeURIComponent(str);
var decoded = decodeURIComponent(encoded);
application.output(encoded); //my%20code.asp%3fname%3d%5bcool%5d
application.output(decoded); //my code.asp?name=[cool]

eval(expression)

Evaluates JavaScript code passed as a string. Returns the value returned by the evaluated code.

Parameters String expression ;

Returns Object

Sample

eval("var x = 2 + 3;");
application.output(x); // prints: 5.0

isFinite(n)

Returns true if the given number is a finite number.

Parameters Number n ;

Returns Boolean

Sample

application.output(isFinite(1)); // prints: true
application.output(isFinite(Infinity)); // prints: false
application.output(isFinite(isNaN)); // prints: false

isNaN(value)

The NaN property indicates that a value is 'Not a Number'.

Parameters Object value ;

Returns void

Sample

isNaN( value )

isXMLName(name)

Returns true if the given name can be used as a valid name for an XML element or attribute.

Parameters String name ;

Returns Boolean

Sample

application.output(isXMLName("good_name")); // prints: true
application.output(isXMLName("bad name")); // because of the space, prints: false

parseFloat(text)

Makes a floating point number from the starting numbers in a given string.

Parameters String text ;

Returns Number

Sample

parseFloat('string')

parseInt(text)

Makes a integer from the starting numbers in a given string in the base specified.

Parameters String text ;

Returns Number

Sample

parseInt('0774')

parseInt(text, radix)

Makes a integer from the starting numbers in a given string in the base specified.

Parameters String text ; Number radix ;

Returns Number

Sample

parseInt('0774' , 8)

uneval(obj)

Returns the string representation behind a given object.

Parameters Object obj ;

Returns String

Sample

application.output(uneval(isNaN)); // prints something like: function isNaN() { [native code for isNaN, arity=1] }
