Element Detail
Input
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create with type "input".

Possible parent array combinations are:
{number|function} x
{number|function} y
{String} value
{String} label

Parent elements for input 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 default value of the input element may be given as string.

The label of the input element may be given as string.



Examples:
 // Create an input element at position [1,4].
 var input = board.create('input', [0, 1, 'sin(x)*x', 'f(x)='], {cssStyle: 'width: 100px'});
 var f = board.jc.snippet(input.Value(), true, 'x', false);
 var graph = board.create('functiongraph',[f,
         function() {
           var c = new JXG.Coords(JXG.COORDS_BY_SCREEN,[0,0],board);
           return c.usrCoords[1];
         },
         function() {
           var c = new JXG.Coords(JXG.COORDS_BY_SCREEN,[board.canvasWidth,0],board);
           return c.usrCoords[1];
         }
       ]);

 board.create('text', [1, 3, '<button onclick="updateGraph()">Update graph</button>']);

 var updateGraph = function() {
     graph.Y = board.jc.snippet(input.Value(), true, 'x', false);
     graph.updateCurve();
     board.update();
 }
