我使用jQuery UI创建了一个jQuery手风琴。
有三个窗格,每个窗格都有一张Google地图。
第一个窗格的地图正确加载,但第二个和第三个窗格的地图无法正确加载。
根据其他StackOverflow线程的建议,我决定在激活窗格时调用map resize和centering函数。
$(document).ready(function(){
$('.the-map').each(function(){
render_map( $(this) );
});
$(function() {
$("#contact-maps").accordion({
collapsible:true,
activate:function (event, ui){
google.maps.event.trigger(map, "resize");
center_map( map );
}
});
});
})(jQuery);
但是,调整大小和居中功能仅适用于最后(第三个)窗格而不适用于第二个窗格。
更新:以下是jsFiddle:http://jsfiddle.net/360sb2bc/
我错过了什么?
答案 0 :(得分:2)
您只在其中一个地图对象上调用google.maps.trigger(map,'resize')
。
working fiddle(创建一个map
个对象数组,并在手风琴改变时调用所有这些对象的调整大小)
