我的google地图中有一堆带有infowindows的标记。
最初我将内容设置为<input type="text" ...>
和提交按钮。在提交按钮的onclick="return submitForm();"
上,我调用了一个函数,该函数应该改变它所执行的信息窗口的内容。但当我关闭infowindow并再次打开它时,文本正在重置。我怎么能留下来?
infowindow.setContent("This HTML content is being reset after reopening the infowindow");
infowindow.open(map, marker);
非常感谢!

编辑:
初始化:
function addCoordinate(lat, lon, text){
var marker = new google.maps.Marker({
position: (new google.maps.LatLng(lat, lon)),
title: '#' + path.getLength(),
map: map,
icon: image3
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent('<input type="text" id="wpname" value="'+ name +'" style="width:200px"><input type="hidden" id="wplat" value="'+ lat +'"><input type="hidden" id="wplon" value="'+ lon +'"><input type="submit" value="OK" onclick="return submitForm();"><br>'+ text +'<br><a href="javascript:removeCoordinate('+lat+', '+lon+');">Remove</a>');
infowindow.open(marker.get('map'), marker);
});
}
要调用的函数:
function submitForm() {
infowindow.setContent("This HTML content is being reset after reopening the infowindow");
infowindow.open(map, marker);
}
每当我点击提交按钮时,内容应该从表单更改为“此HTML内容正在重置[...]”。当我关闭infowindow并再次打开它时,仍然应该显示消息“此HTML内容正在重置[...]”。
现在正使用提交按钮将其设置回表单。

您必须以与所点击的标记相关的方式存储内容。最好的方法是将其直接存储为标记的属性(并在submitForm
更新此标记属性)
function initialize() {
var goo = google.maps,
map = new goo.Map(document.getElementById("map-canvas"), {
center: new goo.LatLng(-34.397, 150.644),
zoom: 8
}),
infowindow = new google.maps.InfoWindow;
function addCoordinate(lat, lon, text) {
var node = document.createElement('div'),
marker = new goo.Marker({
position: (new goo.LatLng(lat, lon)),
map: map,
content: node
});
node.innerHTML =
'<input type="text" id="wpname" value="' + name + '" style="width:200px">' +
'<input type="hidden" id="wplat" value="' + lat + '">' +
'<input type="hidden" id="wplon" value="' + lon + '">' +
'<input type="submit" value="OK" ><br>' + text +
'<br><a href="#">Remove</a>';
function submitForm() {
marker.set('content', 'This marker has been stored');
goo.event.trigger(marker, 'click')
}
function removeCoordinate() {
marker.setMap(null);
}
goo.event.addDomListener(node.querySelector('input[type=submit]'), 'click', submitForm)
goo.event.addDomListener(node.querySelector('a'), 'click', removeCoordinate)
goo.event.addListener(marker, 'click', function() {
infowindow.setContent(this.get('content'));
infowindow.open(marker.get('map'), marker);
});
}
goo.event.addListener(map, 'click', function(e) {
addCoordinate(e.latLng.lat(), e.latLng.lng(), 'some text');
});
window['alert']('click on the map to add a marker')
}
google.maps.event.addDomListener(window, 'load', initialize);
