Directions Question

[jaykapalczynski]

I am using this: Directions | ArcGIS API for JavaScript 3.23 

2 QUESTIONS:

Is there a way to do a map click and record the XY in the To and From fields instead of entering an address or using the GPS locator? 

• Can I add parameters to the widget for XY To and From?
• I can add a button to capture the XY into a variable but dont know if I can push that variable value to the To and From before running the widget

How do I clear the directions after the widget is run.  Looking for a clear all

I got the answer to my 2nd question....I used the parameter showClearButton

Still looking for the first question regarding adding XY from map click

Jay,

  Sure just click the button I outlined in the image:

Boy I feel stupid...thanks

I wonder if you could set the innerhtml of each text box, their id's are esri_dijit_Search_1_input and esri_dijit_Search_2_input?

Jay,

I have done this a few different ways.  The first I create a context menu of the clicked location with one of the selections being adding the point to your directions.  The second uses a button to click that adds the location to driving directions.  The third method uses the current vehicle position and a call location.  Both locations are added as stops and driving directions are calculated.

Here is the code I used:

// context menu
function createMapMenu() {
 // Creates right-click context menu for map
 mapMenu = new Menu({
 onOpen: function(box) {
 // Lets calculate the map coordinates where user right clicked.
 // We'll use this to create the graphic when the user clicks
 // on the menu item to "Add Point"
 menuLocation = getMapPointFromMenuPosition(box); 
 }
 });
 
 mapMenu.addChild(new MenuItem({label: "Copy lat,lon to Clipboard", onClick: copyCoordinates}));
 mapMenu.addChild(new MenuSeparator());
 mapMenu.addChild(new MenuItem({label: "Copy Address to Clipboard", onClick: copyAddress}));
 mapMenu.addChild(new MenuSeparator());
 mapMenu.addChild(new MenuItem({label: "Display Street View", onClick: displayMenuStreetView}));
 mapMenu.addChild(new MenuSeparator());
 mapMenu.addChild(new MenuItem({label: "Add Driving Directions Stop", onClick: addDrivingDirectionsStop}));
 mapMenu.addChild(new MenuSeparator());
 mapMenu.addChild(new MenuItem({label: "Identify Features", onClick: menuIdentify}));
 mapMenu.addChild(new MenuSeparator());
 mapMenu.addChild(new MenuItem({label: "Find Prefire Plans", onClick: menuFindPrefirePlans}));
 mapMenu.startup();
 mapMenu.bindDomNode(map.container);
}
function addDrivingDirectionsStop() {
 reverseLocator.locationToAddress(menuLocation, 200, addAddressedStop);
}
function addAddressedStop(e) {
 var mstop = {name: e.address.Address, feature: {geometry: {x: menuLocation.x, y: menuLocation.y, spatialReference: {wkid: 102100}}, attributes: {info: "stop"}}};
 directions.addStop(mstop);
}
// button with xy data directions
function directionsButton() {
 $("#btnUnitDirections" + unitText).data('btnUnitDirections'+unitText, {pt: unitPoint, info: "Vehicle: " + unitText});
 $("#btnUnitDirections" + unitText).on('click', updateDirectionsLocation);
}
function updateDirectionsLocation(evt) {
 var id = evt.currentTarget.id;
 var data = $("#" + id).data(id);
 var latLng = data.pt;
 var pt = webMercatorUtils.geographicToWebMercator(latLng);
 var info = data.info;
 var stopObject = {name: info, feature: {geometry: {x: pt.x, y: pt.y, spatialReference: {wkid: 102100}}, attributes: {info: info}}};
 directions.addStop(stopObject);
}
function callDrivingDirections() { 
 // create driving directions from the unit to the call 
 // create the vehicle stop
 var vPt = webMercatorUtils.geographicToWebMercator(myUnitPoint);
 var vstop = {name: "Current Vehicle Location...", feature: {geometry: {x: vPt.x, y: vPt.y, spatialReference: {wkid: 102100}}, attributes: {info: myUnitInfo}}};
 directions.addStop(vstop);
 // create the call stop
 var cPt = webMercatorUtils.geographicToWebMercator(myCallPoint);
 var cstop = {name: myCallInformation, feature: {geometry: {x: cPt.x, y: cPt.y, spatialReference: {wkid: 102100}}, attributes: {info: myCallInformation}}};
 directions.addStop(cstop);
 directions.zoomToFullRoute();

 I hope this is helpful!
