我想知道是否有人可以帮助我。
我正在使用下面的代码将图片加载到HTML页面上,这些页面与当前的“位置”和“用户”ID相关。
<div id="galleria">
<?php
$dirlist = getFileList($galleryPath, true);
$x = 0;
foreach($dirlist as $file) {
if((preg_match("/\.jpg$/", $file['name'])) or (preg_match("/\.jpeg$/", $file['name'])) or (preg_match("/\.png$/", $file['name'])) or (preg_match("/\.bmp$/", $file['name'])) or (preg_match("/\.gif$/", $file['name']))) {
echo "<img src='{$file['name']}' />";
$x = 1;
}
}
if ($x == 0) {
echo "<img src='images/noimage.jpg' />";
}
?>
</div>
这很好用,但我在这两个方面遇到了困难。我试图只显示第一张图像并将该图像放在“Infowindow”而不是主页面上。但我必须绝对诚实,并说我甚至不确定从哪里开始。我花了几天时间来达到这一点。
以下代码是脚本中的提取,用于创建标记和Infowindow。
downloadUrl("loadlocationfinds.php?locationid=<?php echo $lid?>", function(data) {
var xml = data.responseXML;
var markers = xml.documentElement.getElementsByTagName("marker");
var bounds = new google.maps.LatLngBounds();
for (var i = 0; i < markers.length; i++) {
var findid = markers[i].getAttribute("findid");
var locationid = markers[i].getAttribute("locationid");
var findosgb36lat = markers[i].getAttribute("findosgb36lat");
var findosgb36lon = markers[i].getAttribute("findosgb36lon");
var findcategory = markers[i].getAttribute("findcategory");
var point = new google.maps.LatLng(
parseFloat(markers[i].getAttribute("findosgb36lat")),
parseFloat(markers[i].getAttribute("findosgb36lon")));
var html = "<span class='h3 orange'><strong>" + 'Item Found: ' + "</strong></span><br>" + finddescription + "<br>";
var icon = customIcons[findcategory] || {};
var marker = new google.maps.Marker({
map: map,
position: point,
title: 'Click to view details',
icon: icon.icon,
shadow: icon.shadow,
formfindosgb36lat: findosgb36lat,
formfindosgb36lon: findosgb36lon,
formfindcategory: findcategory,
});
bounds.extend(point);
map.fitBounds(bounds);
bindInfoWindow(marker, map, infoWindow, html);
google.maps.event.addListener(marker, "click", function() {
document.getElementById('findosgb36lat').value = this.formfindosgb36lat;
document.getElementById('findosgb36lon').value = this.formfindosgb36lon;
document.getElementById('findcategory').value = this.formfindcategory;
});
}
});
}
function bindInfoWindow(marker, map, infoWindow, html) {
google.maps.event.addListener(marker, 'click', function() {
infoWindow.setContent(html);
infoWindow.open(map, marker, html);
});
}
我只是想知道是否有人可以看一下这个并提供一些帮助,以便我只能在'Infowindwow'中显示第一张图片。
非常感谢和最诚挚的问候
答案 0 :(得分:0)
图像被添加到信息窗口的html中
即
........................
var html = "<span class='h3 orange'><strong>" + 'Item Found: ' + "</strong></span><br>" + finddescription + "<br>";
html+= "<img src=\"image.jpg\" alt=\"My Image\" height=\"Ypx\" width=\"Xpx\"><br>";
........................
X 和 Y 是整数
