-
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create
with type "text".
- Possible parent array combinations are:
-
{number|function} x
{number|function} y
{String|function} str
- Parent elements for text elements.
x and y are the coordinates of the lower left corner of the text box. The position of the text is fixed, x and y are numbers. The position is variable if x or y are functions.
The text to display may be given as string or as function returning a string. There is the attribute 'display' which takes the values 'html' or 'internal'. In case of 'html' a HTML division tag is created to display the text. In this case it is also possible to use ASCIIMathML. Incase of 'internal', a SVG or VML text element is used to display the text.
- See:
- JXG.Text
- Examples:
// Create a fixed text at position [0,1].
var t1 = board.create('text',[0,1,"Hello World"]);
// Create a variable text at a variable position.
var s = board.create('slider',[[0,4],[3,4],[-2,0,2]]);
var graph = board.create('text',
[function(x){ return s.Value();}, 1,
function(){return "The value of s is"+s.Value().toFixed(2);}
]
);
