目前在让 jQuery Mobile 和 Leaflet 一起玩时遇到问题。我似乎无法让传单在“pageinit”上调整地图的大小,而是在左上角的一个小框中弹出。
缩放级别也不正确。我已经尝试设置超时和 invaidateSize 方法,但我仍然遇到问题。我也在使用固定的页眉和页脚,控件被它们挡住了视线。这是页面的代码
<div data-role="page" data-theme="d" id="eventMap" data-add-back-btn="true">
<div data-role="header" data-position="fixed" data-id="pageheader">
<h1>Find Events</h1>
</div>
<div data-role="content" class="ui-content">
<div id="mapcanvas"></div>
</div>
<div data-role="footer" data-position="fixed" data-id="pagefooter">
<div data-role="navbar">
<ul>
<li><a href="eventmap.php" class="ui-btn-active">Map</a></li>
<li><a href="eventlist.php">List</a></li>
</ul>
</div>
</div>
<script type="text/javascript">
function resize() {
var content, contentHeight, footer, header, viewportHeight;
window.scroll(0, 0);
header = $(":jqmData(role='header'):visible");
footer = $(":jqmData(role='footer'):visible");
content = $(":jqmData(role='content'):visible");
viewportHeight = $(window).height();
contentHeight = viewportHeight - header.outerHeight() - footer.outerHeight();
$(":jqmData(role='content')").first().height(contentHeight);
return $("#mapcanvas").height(contentHeight);
};
$('#eventmap').live('pageinit orientationchange resize', resize);
$('#eventMap').live('pageinit', function() {
//MAP
var tiles, map;
map = new window.L.Map('mapcanvas');
tiles = new L.TileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {maxZoom: 18, attribution: 'Eventi8'});
map.addLayer(tiles);
map.locateAndSetView(16);
map.on('locationfound', onLocationFound);
function onLocationFound(e) {
var circle = new L.Circle(e.latlng, 30);
map.addLayer(circle);
var url = 'inc/eventdistancejson.php?lat='+e.latlng.lat+'&long='+e.latlng.lng+'&radius=30';
$.getJSON(url, function (data) {
$.each(data.events, function(i, event){
var location = new L.LatLng(event.location.lat, event.location.lng);
var marker = new L.Marker(location);
marker.bindPopup('<div style="text-align: center; margin-left: auto; margin-right: auto;"><h3>' + event.name + '</h3> <p><a href="event.php?eid='+event.id+'">Event Link</a></p></div>', {maxWidth: '360'});
map.addLayer(marker);
});
});
}
// Remake Map
setTimeout(function(){
map.invalidateSize();
}, 1);
});
</script>
</div>
谢谢你提供的所有帮助。我也遇到了在错误页面上加载 JSON 并且 pageinit 事件被触发两次的问题,但那是另一个问题!
