The JavaScript code

The point "p0" controls the movement of the line. Of course, p0 should be hidden.

var brd = JXG.JSXGraph.initBoard('jxgbox', {boundingbox: [-10, 10, 10, -10], axis: true, grid: false});
var p0 = brd.createElement('point', [0,0], {name:'T'});
var p1 = brd.createElement('point', [7, 5], {name:'A'});
var p2 = brd.createElement('point', [5, 7], {name:'B'});
var l = brd.createElement('line', [p1,p2], {name:''});
var t = brd.createElement('transform', [function(){return p0.X();},function(){return p0.Y();}], {type:'translate'});

function startAnimation1() {
function startAnimation2() {
<span onClick="startAnimation1()" style="color:blue">Click here, to start animation 1</span>
<span onClick="startAnimation2()" style="color:red">Click here, to start animation 2</span>
