How to change algorithms (ch.disable=true) in the JS graphhopper-client

Hi,

Using GH’s JS client demo and Route Optimization API for discussion:

graphhopper/directions-api-js-client/blob/master/js/demo.js

var iconObject = L.icon({
    iconUrl: './img/marker-icon.png',
    shadowSize: [50, 64],
    shadowAnchor: [4, 62],
    iconAnchor: [12, 40]
});

$(document).ready(function (e) {
    jQuery.support.cors = true;

    $(".tab-content").css("display", "none");
    $(".tabs-menu a").click(function (event) {
        // event.preventDefault();
        showTab($(this));
    });

    function showTab(thisDiv) {
        thisDiv.parent().addClass("current");
        thisDiv.parent().siblings().removeClass("current");
        var tab = thisDiv.attr("href");

When instantiating a new GraphHopper.Routing object, how do you set ch.disable=true or the weighting? I want to enable turn restrictions and dynamically change the vehicle profile for a travelling salesman application I’m prototyping.

Thank you

You can provide these parameters per request:

ghRouting.doRequest({weighting:"fastest", ch: {disabled: true}}).
then(function(json) {
    ...
}).catch(function(err) {
   ...
});
