How to re-center a map using jquery-ui-map

javascriptjquerygoogle-mapsjquery-ui-map

提问by Andreas Jung

Using jquery-ui-map.

使用 jquery-ui-map。

I am loading data through JSON with some marker and the latitude/longitude of the new center of the map (location finder application).

我正在通过带有一些标记和地图新中心(位置查找器应用程序)的纬度/经度的 JSON 加载数据。

var origin = new google.maps.LatLng(data.origin.latitude, data.origin.longitude)

// adding the marker for the new origin works
$('#map_canvas').gmap('addMarker', {'position': origin});

// does not work
$('#map_canvas').gmap('center', '49, 7');

// does not work
$('#map_canvas').gmap('center', origin);

// does not work
$('#map_canvas').gmap('center', {'position': origin});

All of the three center calls fail:

所有三个中心呼叫都失败了:

Uncaught TypeError: Cannot call method 'apply' of undefined
$.a.$.fn.(anonymous function)jquery.ui.map.js:46
b.extend.eachjquery.js:35
b.fn.b.eachjquery.js:28
$.a.$.fn.(anonymous function)jquery.ui.map.js:40
(anonymous function)@@geosearch:477
c.extend.handleSuccessjquery.js:144
c.extend.ajax.w.onreadystatechange

What is the canonical way here?

这里的规范方式是什么?

Use this:

用这个:

$('#map_canvas').gmap('get','map').setOptions({'center':origin});

There are two ways, either get the map and use the native setter:

有两种方法,要么获取地图,要么使用原生 setter:

var map = $("#map_canvas").gmap("get", "map");
map.setCenter(origin);

Or you use the plugin option setter

或者你使用插件选项设置器

$("#map_canvas").gmap("option", "center", origin);

回答by Roberto

with panTo, you can re-center the map

使用 panTo,您可以将地图重新​​居中

jQuery('#map_canvas').gmap.panTo(new google.maps.LatLng('0.00','0.00'));

回答by ilConfa

you must use 'option'before position centering...

您必须'option'在位置居中之前使用...

...like example below (I used button click event and some other option):

...就像下面的例子(我使用了按钮点击事件和其他一些选项):

$("#button").click( function(){
var latLng = new google.maps.LatLng(data.origin.latitude, data.origin.longitude);
$('#map_canvas').gmap('option', 'center', latLng);
$('#map_canvas').gmap('option', 'zoom', 7);     
$('#map_canvas').gmap('addMarker', {position: latLng,bounds: false});   
});

hope help you.

希望能帮到你。
