The underlying JavaScript code
var brd = JXG.JSXGraph.initBoard('jxgbox',{boundingbox: [-1,10,7,-1], axis:false, keepaspectratio:false});
// Vertical line at x=3
var A = brd.create('point', [2, 5], {strokeWidth:1, dash:2});
brd.create('text', [3, 8, function () { return 'X(A) = ' + A.X(); }]);
brd.on('update', function () {
document.getElementById('out').innerHTML = 'X(A) = ' + A.X();
});
<div id="out"></div>
