谷歌 Map 缩放控件和标记消失

提问于

我在谷歌 Map 上遇到了两个非常奇怪的问题，这些问题似乎只发生在Chrome / Mac和Chrome / Windows上

  • 如果单击位于科罗拉多州的第一个引脚并尝试平移 Map ，将鼠标向右移动，您会发现缩放控件将开始消失 . 我已经尝试用max-width修复它：无;所以这不是同一个bug .

  • 如果单击位于Skopje的右侧标记，您会注意到标记将在缩放级别20处消失

更新：如果我在Chrome上禁用硬件加速，这两个错误都是固定的，所以我认为这比谷歌 Map 更多的是Chrome问题 .

这是一个重现问题的jsfiddle链接http://jsfiddle.net/sokarovski/rx74P/2/

var posSkopje = new google.maps.LatLng(42.007652282715,21.372894287109034);
var posColorado = new google.maps.LatLng(38.960487365723,-104.76946258545001);

google.maps.visualRefresh = false;
var map = new google.maps.Map(document.getElementById("map_canvas"), {
    center: new google.maps.LatLng(0, 0),
    zoom: 3,
    mapTypeId: google.maps.MapTypeId.HYBRID,
    maxZoom: 20
});

var markerSkopje = new CustomMarker('img.svg');
markerSkopje.setPosition(posSkopje);
markerSkopje.setMap(map);

var markerColorado = new CustomMarker('img.svg');
markerColorado.setPosition(posColorado);
markerColorado.setMap(map);

var zoomOnClick = function(arg1) {
    map.setCenter(this.getPosition());
    map.setZoom(22);
}

google.maps.event.addListener(markerColorado, 'open', jQuery.proxy(zoomOnClick, markerColorado));
google.maps.event.addListener(markerSkopje, 'open', jQuery.proxy(zoomOnClick, markerSkopje));

    这个帖子很老了，但问题仍然存在 . 对于其他人，磕磕绊绊;你可以这样做：

    从谷歌制作Markermanager.js的本地副本并修改此行（第107行）

    From:

    me.maxZoom_ = opt_opts.maxZoom || 19;

    To:

    me.maxZoom_ = opt_opts.maxZoom || 21;

    代码中的一些问题看看这个

    //=========== > Custom Marker Class
function CustomMarker(opts) {
    this.location_ = null;
    this.div_ = null;
    this.inner_ = null;
    this.opts = {
        image:      null
    }
    this.constructor = function(image) {
        this.inner_ = document.createElement('img');
        jQuery(this.inner_).addClass('thumb').click(jQuery.proxy(this.onPinClick, this));
        if (image) this.setImage(image);
    }
    this.setPosition = function(ll) {
        this.location_  = ll;
    }
    this.getPosition = function() {
        return this.location_;
    }
    this.onAdd = function() {
        var div = document.createElement('div');
        div.style.border = "none";
        div.style.borderWidth = "0px";
        div.style.position = "absolute";
        div.appendChild(this.inner_);
        this.div_ = div;
        var panes = this.getPanes();
        panes.overlayMouseTarget.appendChild(div);
    }
    this.onPinClick = function(e) {
        google.maps.event.trigger(this, 'open');
    }
    this.draw = function() {
        var overlayProjection = this.getProjection();
        if (overlayProjection) {
            var pixPosition = overlayProjection.fromLatLngToDivPixel(this.location_);
            this.div_.style.left = (pixPosition.x ) + "px";
            this.div_.style.top = (pixPosition.y) + "px";
        }
    }
    this.setImage = function(image) {
        this.inner_.src = image;
    }
    this.constructor.apply(this, arguments);
}
CustomMarker.prototype = new google.maps.OverlayView();
//=========== > Initialization 
var posSkopje = new google.maps.LatLng(42.007652282715,21.372894287109034);
var posColorado = new google.maps.LatLng(38.960487365723,-104.76946258545001);

var map = new google.maps.Map(document.getElementById("map_canvas"), {
    center: new google.maps.LatLng(0, 0),
    zoom: 3,
    mapTypeId: google.maps.ROADMAP,
    maxZoom: 20
});

var markerSkopje = new CustomMarker('http://www.gnhl.ca/images/pushed-pin-hi.png');
markerSkopje.setPosition(posSkopje);
markerSkopje.setMap(map);

var zoomOnClick = function(arg1) {
    map.setCenter(this.getPosition());
    map.setZoom(20);
}

google.maps.event.addListener(markerSkopje, 'open', jQuery.proxy(zoomOnClick, markerSkopje));
