[英]Google maps listener event acts like a click even though it is a mouseover
我正在添加這兩個google.maps.event.addListener事件
google.maps.event.addListener(markerAcademicCenter, "mouseover", function (e) {
markerIconAcademicCenter.url = 'MapIcons/Circle32.png'
});
google.maps.event.addListener(markerAcademicCenter, "mouseout", function (e) {
markerIconAcademicCenter.url = 'MapIcons/Circle64.png'
});
在已經具有點擊事件的標記下方。
google.maps.event.addListener(markerAcademicCenter, "click", function (e) {
$(".campusMapInfoPanel > div").appendTo($(".InfoStorageDiv"));
$(".InfoPanelAcademicCenter").appendTo($(".campusMapInfoPanel"));
this.setZIndex(google.maps.Marker.MAX_ZINDEX + 1);
setZoomWhenMarkerClicked();
CampusMap.setCenter(markerAcademicCenter.getPosition());
});
這些事件上方的markerIconAcademicCenter.url
已設置為Circle64。 我希望頁面以較大的圓圈(64x64)加載,當我將鼠標懸停並離開標記區域時會來回切換。
我有兩個問題
function buildingFocus(markerName) {google.maps.event.trigger(markerName, "click");}
會重置圖標,就好像它是mouseout事件一樣。 為了進一步測試這種意外行為,我一次注釋了每個事件。 為了弄清楚實際上正在發生什么,我首先將初始圖像更改為clear.png。
當我取出mouseover事件時,在頁面加載后我第一次單擊建築事件或菜單鏈接時,圖像沒有改變。 在刪除mouseover事件之前,單擊菜單作為頁面加載后的第二次單擊,將圖標更改為mouseout圖像,但是現在單擊建築物會導致這種情況。
當我拿出mouseout事件時,單擊建築物是第一次將鼠標圖標更改為鼠標懸停圖像,然后再次單擊任一區域則沒有任何作用。 如果在第一次或以后單擊時單擊菜單鏈接,則圖像沒有變化,但是單擊建築物后,圖像就發生了變化。
當我取出click事件時,圖像從未改變。 就其本身而言,click事件在兩個位置都可以正常工作。
嘗試使用這個:
google.maps.event.addListener(markerAcademicCenter, "mouseover", function (e) {
markerIconAcademicCenter.setIcon('url to icon');
});
而不是下面的代碼:
google.maps.event.addListener(markerAcademicCenter, "mouseover", function (e) {
markerIconAcademicCenter.url = 'MapIcons/Circle32.png'
});
這樣可以解決鼠標懸停和鼠標懸停時圖標大小更改的問題。
標記的圖標不是MVCObject,API將不會觀察到圖標屬性的更改。
您必須修改圖標的url
,然后調用setIcon
以應用更改:
google.maps.event.addListener(markerAcademicCenter, "mouseover", function (e) {
var icon = this.getIcon();
icon.url = 'url/to/icon';
this.setIcon(icon);
});
但是我不建議這樣做,當您將圖標用於多個標記時,更改url
(或其他屬性)將影響原始圖標markerIconAcademicCenter
(標記使用對原始對象的引用)。 您最好使用修改后的網址創建一個副本:
google.maps.event.addListener(markerAcademicCenter, "mouseover", function (e) {
var icon = this.getIcon(),copy={};
for(var k in icon){
copy[k]=icon[k];
}
copy.url= 'url/to/icon';
this.setIcon(copy);
});
您可以檢查下面的代碼,以便您清楚我的意思:
