我正在使用Yii 框架和 Yii egmap extension开发交互式地图。当用户单击如图所示的复选框时，我想刷新地图（ajax）：
我只能使用以下代码在服务器端（刷新整个页面）执行此操作：
<?php
Yii::app()->clientScript->registerScript('filterscript',"
$('#filter_all').click(function() {
$(\"input[name='filter\[\]']\").prop('checked', this.checked);
window.location.href = 'http://' + window.location.host + window.location.pathname + '?tags=sale,rent,residential,commercial,agricultural';
});
$(\"input[name='filter\[\]']\").click(function() {
var tags = '?tags=';
var tmp=new Array();
$('#filter_all').prop('checked', !$(\"input[name='filter\[\]']:not(:checked)\").length);
$('input[type=checkbox]').each(function () {
if (this.checked)
tmp.push($(this).val());
});
tags += tmp.join(',');
window.location.href = 'http://' + window.location.host + window.location.pathname + tags;
});
$('#filter_all').prop('checked', !$(\"input[name='filter\[\]']:not(:checked)\").length);
",CClientScript::POS_READY);
?>
并且地图是使用带有以下代码的 EGMap 扩展生成的：
<?php
// Get latlong from location-aware web browser saved in cookie
if (isset($_COOKIE['latlng'])){
list($lat,$long) = explode(',',htmlentities(htmlspecialchars(strip_tags($_COOKIE['latlng']))));
}else{
$lat = 3.159553312559541;
$long = 101.71481802016604;
}
Yii::import('ext.gmap.*');
$gMap = new EGMap();
$gMap->setJsName('map');
$gMap->zoom = 10;
$mapTypeControlOptions = array(
'sensor'=>true,
'position'=> EGMapControlPosition::LEFT_BOTTOM,
'style'=>EGMap::MAPTYPECONTROL_STYLE_DROPDOWN_MENU
);
$gMap->mapTypeControlOptions= $mapTypeControlOptions;
$gMap->setWidth('100%');
$gMap->setHeight(500);
$gMap->setCenter($lat, $long);
$icon = new EGMapMarkerImage("http://".$_SERVER['HTTP_HOST'].Yii::app()->baseUrl."/images/bighouse.png");
$icon->setSize(32, 37);
$icon->setAnchor(16, 16.5);
$icon->setOrigin(0, 0);
// Status label

$condition = '';

$info_window = new EGMapInfoWindow('<div style="height:'.$win_height.'">'.
$prop_photo.
substr($prop['description'],0,40).'...'.'<br />'.
'Price: '.$prop['price'].'<br />'.
'Email: '.$email_img.'<br />'.
'Tel: '.$prop['contact_phone'].'<br />'.
$status_label.' Added: '.$prop['date_upload'].'<br />'.
$links.
'</div>');
$marker = new EGMapMarker($prop['latitude'], $prop['longitude'], array('title' => $prop['title'],'icon'=>$icon));
$marker->addHtmlInfoWindow($info_window);
$gMap->addMarker($marker);
}
}
$gMap->renderMap();
?>
所有这些代码都在视图文件中。地图由 id 的 html 元素中的 EGMap 扩展生成EGMapContainer0。知道如何在单击复选框的情况下通过 ajax 刷新地图吗？
谢谢。
