Re: zoom to bounding box url for SDK

[ Edited ]

You can place it anywhere to a script which is loaded by the Portal, so e.g. HelloWorld.js, or other custom script. Of course do not embed any irrelevant code inside such as creating the Hello World button, I left it there by mistake.


This is the fully working code. I have rewritten the parameter getter because this one looks better :-)


window.onload = function () {

function getURLParameter(name) {
  return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search) || [null, ''])[1].replace(/\+/g, '%20')) || null;

function zoomToBBox() {
    bbox = getURLParameter("bounds");
    if (bbox == null) return;
    bbox = bbox.split(",");

    //sample points in EPSG:4326
    var bottomLeftCorner = { x: bbox[0], y: bbox[1] },
        topRightCorner = { x: bbox[2], y: bbox[3] };

        points: [bottomLeftCorner, topRightCorner],
        sourceCrsId: "EPSG:4326", 
        targetCrsId: $GP.crs.getCurrent(),
    }, function (transformationResult) {
        // get BBOX in form minx, miny, maxx, maxy
        var points = transformationResult.points,
            bbox = [points[0].x, points[0].y, points[1].x, points[1].y];
            bbox: bbox
        }, function () {
            // display information

Re: zoom to bounding box url for SDK

This works great!  Map redraws in the correct spot after portal loads.
