我从 ajax 页面加载标记和折线,索引页面上显示的每个请求数据,现在我想在从 ajaxPage 获取新数据之前清除数据(标记、折线、...)
索引页:
var gmarkers = [];
var map = null;
function initialize() {
var myOptions = {
zoom: 15,
center: new google.maps.LatLng(35, 53),
// mapTypeControlOptions: {style: google.maps.MapTypeControlStyle.DROPDOWN_MENU},
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
google.maps.event.addListener(map, 'click', function() {
infowindow.close();
});
}
var infowindow = new google.maps.InfoWindow(
{
size: new google.maps.Size(150,50)
});
function myclick(i) {
google.maps.event.trigger(gmarkers[i], "click");
}
function createMarker(latlng, name, html) {
var contentString = html;
var marker = new google.maps.Marker({
position: latlng,
map: map,
zIndex: Math.round(latlng.lat()*-100000)<<5
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(contentString);
infowindow.open(map,marker);
});
// save the info we need to use later for the side_bar
gmarkers.push(marker);
}
Ajax 页面(record2.php):
var polylines = [];
var beaches = [
['Bondi Beach',10,15, 4],
['Coogee Beach',11,16, 5],
['Cronulla Beach',13,15, 3],
['Manly Beach',13,17, 2],
['Maroubra Beach',12,10, 1]
];
for (var i = 0; i < beaches.length; i++) {
var beach = beaches[i];
var myLatLng = new google.maps.LatLng(beach[1], beach[2]);
// var polylines = new google.maps.LatLng(beach[1], beach[2]);
polylines.push(new google.maps.LatLng(beach[1], beach[2]));
var marker = createMarker(myLatLng,"This place",beach[0])
}
var routes = new google.maps.Polyline({
path: polylines,
strokeColor: "#FF0000",
strokeOpacity: 0.6,
strokeWeight: 4
});
routes.setMap(map);
问题:在加载新数据之前清除折线、标记等的简单方法ajax page
?
/--- 编辑 ---/
我检查了Google Maps API v3 的答案:如何删除所有标记?但只是来自请求页面的第一个请求是响应,下一个请求将不起作用,我想我错误地添加了清晰的地图功能
从索引调用 AjaxPage:
$(document).ready(function(){
$('#loader').hide();
$("#search_button").click(function() {
$('#loader').fadeIn(200);
$('#login_group').slideUp(200);
$.post("record2.php", {
time: $('#login_username').val()
}, function(response){
setTimeout("finishAjax('login_group', '"+escape(response)+"')", 200);
});
return false;
});
});
function finishAjax(id, response){
$('#loader').slideUp(300);
$('#'+id).html(unescape(response));
$('#'+id).fadeIn(200);
}
