I want same to do with javaScript. This must be really simple but i could not find the way . please help thanks in advance



There’s a couple of ways you can do this. The easiest method is to just call that function:

var Chkinput = document.getElementById("laneFilter");
Chkinput .onchange();

If you need it to simulate the real event in full, or if you set the event via the html attribute or addEventListener/attachEvent, you need to do a bit of feature detection to correctly fire the event:

if ("createEvent" in document) {
    var evt = document.createEvent("HTMLEvents");
    evt.initEvent("change", false, true);
