Center / Zoom Scatter Map
Introduction
The following article will explain how to center and zoom scatter map.
Purpose/Benefits
This script allows you to center and zoom a map according to a given latitude and longitude.
Example
In the Example below we want to center the map to China and set the zoom to 8.
Steps
STEP 1 - FIND LATITUDE AND LONGITUDE
You can find the latitude and longitude using google maps
STEP 2 - ADD WIDGET SCRIPT
/********************************************************/
/********Set and Center a Map**********/
/********************************************************/
__first_load__ = true;
widget.on("beforeviewloaded", function (widget, args){
var map = args.options.map;
window.map = map;
});
widget.on("domready", function (widget, args){
if (__first_load__){
setTimeout(function () { window.map.setView([39, 116], 8);}, 500);
}
__first_load__ = false;
});For multi-map support, please use the following syntax instead:
widget['__first_load__'] = true;
widget.on("beforeviewloaded", function (w, args){
var map = args.options.map;
window['map_'+w.oid] = map;
});
widget.on("domready", function (w, args){
if (widget['__first_load__'] ){
setTimeout(function () { window['map_'+w.oid].setView([39, 116], 8);}, 1000);
}
widget['__first_load__'] = false;
} );Updated 03-02-2023
