在悬停链接或文本上显示谷歌地图

问题描述：

http://coding.pressbin.com/18/Display-a-Google-Map-when-you-hover-over-location-text/我正在关注如何在文本上显示Google地图的本教程。是的，但它出现在一个错误的地方。看，地图显示在页面的底部。当我悬停地图图片时，div本身没有与工作区相比的属性。在悬停链接或文本上显示谷歌地图

工作代码：

<div style="position: absolute; left: 678px; top: 170px; z-index: 999; display: none; padding: 1px; margin-left: 5px; background-color: rgb(51, 51, 51); width: 302px; box-shadow: 0pt 1px 10px rgba(0, 0, 0, 0.5);"> 
<a target="new" href="http://maps.google.com/maps?q=Brookhaven, PA&z=11"> 
<img border="0" src="http://maps.google.com/maps/api/staticmap?center=Brookhaven, PA&zoom=12&size=300x300&sensor=false&format=png&markers=color:blue|Brookhaven, PA"> 
</a> 
</div>

是什么在我的浏览器：

<div style="display: none;"> 
<a target="new" href="http://maps.google.com/maps?q=4417 Edgmont Avenue, 19015&z=11"> 
<img border="0" src="http://maps.google.com/maps/api/staticmap?center=4417 Edgmont Avenue, 19015&zoom=16&size=300x300&sensor=false&format=png&markers=color:blue|4417 Edgmont Avenue, 19015"> 
</a> 
</div>

我失去了对DIV部分。请帮忙！

这对我来说是什么在起作用：

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> 
<head> 
<title>jQuery Test Script</title> 
</head> 
<body> 
<span class="mapThis" place="600 Forbes Ave, Pittsburgh, PA 15282" zoom="16">Duquesne University</span> is located in the great town of <span class="mapThis" place="Pittsburgh, PA" zoom="12">Pittsburgh</span> in the great state of <span class="mapThis" place="Pennsylvania" zoom="6">Pennsylvania</span>. 
<script src="jquery-ui-1.8.16.custom/js/jquery-1.6.2.min.js"></script> 
<script src="scripts/test_script.js"></script> 
</body> 
</html>

这里的jQuery来做到这一点：

// JavaScript Document 
$(document).ready(function() { 
var cursorX; 
var cursorY; 
if (window.Event) { 
    document.captureEvents(Event.MOUSEMOVE); 
} 
document.onmousemove = getCursorXY; 
$(".mapThis").each(function() { 
    var dPlace = $(this).attr("place"); 
    var dZoom = $(this).attr("zoom"); 
    var dText = $(this).html(); 
    $(this).html('<a onmouseover="mapThis.show(this);" style="text-decoration:none; border-bottom:1px dotted #999" href="http://maps.google.com/maps?q=' + dPlace + '&z=' + dZoom + '">' + dText + '</a>'); 
}); 
}); 
var mapThis=function(){ 
var tt; 
var errorBox; 
return{ 
    show:function(v){ 
    if (tt == null) { 
    var pNode = v.parentNode; 
    pPlace = $(pNode).attr("place"); 
    pZoom = parseInt($(pNode).attr("zoom")); 
    pText = $(v).html(); 
    tt = document.createElement('div'); 
    $(tt).html('<a href="http://maps.google.com/maps?q=' + pPlace + '&z=11" target="new"><img border=0 src="http://maps.google.com/maps/api/staticmap?center=' + pPlace + '&zoom=' + pZoom + '&size=300x300&sensor=false&format=png&markers=color:blue|' + pPlace + '"></a>'); 
    tt.addEventListener('mouseover', function() { mapHover = 1; }, true); 
    tt.addEventListener('mouseout', function() { mapHover = 0; }, true); 
    tt.addEventListener('mouseout', mapThis.hide, true); 
    document.body.appendChild(tt);  
} 
fromleft = cursorX; 
fromtop = cursorY; 
fromleft = fromleft - 25; 
fromtop = fromtop - 25; 
tt.style.cssText = "position:absolute; left:" + fromleft + "px; top:" + fromtop + "px; z-index:999; display:block; padding:1px; margin-left:5px; background-color:#333; width:302px; -moz-box-shadow:0 1px 10px rgba(0, 0, 0, 0.5);"; 
tt.style.display = 'block'; 
}, 
hide:function(){ 
tt.style.display = 'none'; 
tt = null; 
} 
}; 
}(); 
function getCursorXY(e) { 
cursorX = (window.Event) ? e.pageX : event.clientX + (document.documentElement.scrollLeft ? document.documentElement.scrollLeft : document.body.scrollLeft); 
cursorY = (window.Event) ? e.pageY : event.clientY + (document.documentElement.scrollTop ? document.documentElement.scrollTop : document.body.scrollTop); 
}

在他的网站上的教程示例中，他没有将鼠标监听器添加到代码中，但是，我发现我t在完整的代码中。 –

这次完美的作品。非常感谢！ – woninana

我知道这个职位是旧的，但我想这可能是有用的，如果有人绊倒这正在寻找一个更新的例子。虽然答案中的代码工作正常，但它不是以jQuery友好格式编写的。我还发现事件监听器的配置方式使它有点困难。最后，地图的固定大小在今天的响应式世界中不起作用。希望这可以帮助别人！在你的页面

<div id='mapHolder' style='whatever you want'></div>

将链接的任何地方，你当鼠标滑过显示什么内容的地图：

在您的网页和风格，随时随地添加#mapHolder根据自己的喜好

<a class="mapthis" place="properly formatted address" zoom="12">MAP</a>

jQuery的：

$(document).on("mouseenter", ".mapthis", function(e) { 
    var desiredMapWidthPercent = .8; 
    var mapWidth = Math.round($(window).width() * desiredMapWidthPercent); 
    var aspectRatio = mapWidth/$(window).height(); 
    var mapHeight = Math.round($(window).height() * aspectRatio); 
    var boxWidth = mapWidth; 
    var boxHeight = mapHeight; 
    var scale = 1; 
    var pZoom = parseInt($(this).attr("zoom")); 
    var pPlace = $(this).attr("place"); 
    if((mapHeight > 640) || (mapWidth > 640)){ 
     mapHeight = Math.round(mapHeight/3.5); 
     mapWidth = Math.round(mapWidth/3.5); 
     scale = 2; 
     if(((mapHeight) > 1280) || ((mapWidth) > 1280)){ 
      mapHeight = 640; 
      mapWidth = 640; 
      boxWidth = 1280; 
      boxHeight = 1280; 
     }else{ 
      boxWidth = mapWidth * 2; 
      boxHeight = mapHeight * 2; 
     } 
    } 
    var fromleft = Math.max(0, ((($(window).width() - boxWidth)/2) + $(window).scrollLeft()))+'px'; 
    var fromtop = Math.max(0, ((($(window).height() - boxHeight)/2) + $(window).scrollTop()))+'px'; 
    var pText = $(this).html(); 
    $('#mapHolder').html('<a href="https://maps.google.com/maps?q=' + pPlace + '&z=11" target="new"><img border=0 src="https://maps.google.com/maps/api/staticmap?center=' + pPlace + '&zoom=' + pZoom + '&size='+mapWidth+'x'+mapHeight+'&scale='+scale+'&sensor=false&format=png&markers=color:blue|' + pPlace + '"></a>'); 
    $('#mapHolder').css({position:'absolute',top:fromtop,left:fromleft, width:boxWidth, z-index:'999'}); 
    $('#mapHolder').show(); 
}); 
$(document).on("mouseleave", ".mapthis", function(e) { 
    if($(e.relatedTarget).closest('#mapHolder').length){ 
     $("#mapHolder").on("mouseleave", function(e) { 
      $('#mapHolder').hide(); 
     }); 
     return; 
    } 
    $('#mapHolder').hide();    
});
