Question

http://coding.pressbin.com/18/Display-a-Google-Map-when-you-hover-over-location-text/我正在按照本教程了解如何在文本上显示谷歌地图。是的，但它出现在错误的地方。看，地图显示在页面底部。当我将鼠标悬停在地图图像上时，div本身与工作图像相比没有任何属性。

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>

我的浏览器中有什么：

<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>

我迷失在div部分。请帮忙！

Answer 1

这对我有用：

<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>

这是实现它的jQuery：

// 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);
 }

我知道这篇文章很老但我觉得如果有人偶然发现并正在寻找更新的例子，那可能会有用。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得它的使用有点困难。最后，地图的固定大小在今天的响应世界中不起作用。希望这有助于某人！

在页面中的任意位置添加#mapHolder，并根据自己的喜好设置样式：

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

将链接放置在页面中的任何位置，以便在鼠标悬停时显示地图：

 <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();            
});
