麻烦让我的鼠标悬停在标记上工作

-1

我在下面创建了我的代码，并在最后使用了mouseover影响，但它不起作用。我把它放在错误的地方吗？我似乎无法得到它的工作。最终，我希望获得某种类型的信息，但每次都要一步一步地尝试让基本工作先行。麻烦让我的鼠标悬停在标记上工作

请提供[最小，完整，测试和可读示例]（HTTP：//计算器.com/help/mcve）问题。我得到一个JavaScript的发布代码：'未捕获的ReferenceError：contentString没有定义' – geocodezip

我已经添加了我的工作的其余部分，将给你一个工作脚本，只是没有任何鼠标悬停，我想 – Kev

它不会在定义'contentString'之前有任何鼠标悬停，这是infowindow中显示的内容，如果它是空/空，没有infowindow ... – geocodezip

您需要：

定义contentString
联想与信息窗口内容的标记。这样做的一种方法是匿名函数关闭，如在此相关问题Google Maps JS API v3 - Simple Multiple Marker Example中，或者使用明确的createMarker函数，如下面的示例中所示。

注：这种做法只会大约10个地址后，它会运行到地理编码速率限制工作。

function createMarker(latlng, html, map) { 
    var infowindow = new google.maps.InfoWindow({ 
    content: html 
    }); 
    var marker = new google.maps.Marker({ 
    map: map, 
    position: latlng 
    }); 
    marker.addListener('mouseover', function() { 
    infowindow.open(map, this); 
    }); 
    marker.addListener('mouseout', function() { 
    infowindow.close(); 
    }); 
}

代码片断：

var markers = []; 
 

 
function createMarker(latlng, html, map) { 
 
    var infowindow = new google.maps.InfoWindow({ 
 
    content: html 
 
    }); 
 
    var marker = new google.maps.Marker({ 
 
    map: map, 
 
    position: latlng 
 
    }); 
 
    marker.addListener('mouseover', function() { 
 
    infowindow.open(map, this); 
 
    }); 
 
    marker.addListener('mouseout', function() { 
 
    infowindow.close(); 
 
    }); 
 
    markers.push(marker); 
 
} 
 

 
//declare namespace 
 
var up206b = {}; 
 

 
//declare map 
 
var map; 
 

 
function trace(message) { 
 
    if (typeof console != 'undefined') { 
 
    console.log(message); 
 
    } 
 
} 
 

 
up206b.initialize = function() { 
 
    var latlng = new google.maps.LatLng(52.136436, -0.460739);

    }; 
 
    map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); 
 
    up206b.geocode(); 
 
} 
 

 
var geocoder = new google.maps.Geocoder();

    for (var i = 0; i < markers.length; i++) { 
 
    markers[i].setMap(null); 
 
    } 
 
    markers = []; 
 
    var bounds = new google.maps.LatLngBounds(); 
 
    var addresses = [$('#address').val(), $('#address2').val()]; 
 

 
    addresses.forEach(function(address) { 
 
    if (address) {
