Possible elements:

Construction Description
A(1,1) Point with name 'A' at the position (1,1)
ZY(0.5|1) Point with name 'ZY' at the position (0.5,1)
]AB[ straight line through the points A and B
[AB[ ray through the points A and B, stopping at A
]AB] ray through the points A and B, stopping at B
[AB] segment through the points A and B
g=[AB] segment through the points A and B, named by 'g'
k(A,1) circle with midpoint A and radius 1
k(A,B) circle with midpoint A through the point B on the circle line
k(A,[BC]) circle with midpoint A and radius defined by the length of the (not necessarily existing) segement [BC]
k_1=k(A,1) circle with midpoint A and radius 1, named by 'k_1'

The different elements have to be separated by semicolon.

The JavaScript code

var board, construction = [];
board = JXG.JSXGraph.initBoard('box', {grid:true, boundingbox:[-1,6,11,-3], keepaspectratio:true, axis:true});

function construct() {
    var t = document.getElementById('input').value;
    construction.push(board.construct(t));
}
