[英]Jquery mobile form response page does not download content from pageinit until refresh of page
[英]jQuery Mobile page does not show content until I Refresh
为什么我的带有两个“移动”页面的html页面必须刷新或移动一些小边缘才能在其中显示我的地图? 请参阅我的小提琴或以下代码:
我有一个包含两个jQuery Mobile页面的移动页面文档(html)。 1.要求您知道您的位置的登录页面。 2. OpenLayers3地图页面,它将打开您的位置并在打开时将地图居中。
我的麻烦是:地图将建立并且将以该位置为中心,但是直到我调整大小后刷新“地图”边缘或浏览器窗口后才会渲染。 我怀疑这与页面事件有关,但不确定。
我有缺少的财产吗?

您可以使用pagecontainer小部件的show事件:
http://api.jquerymobile.com/pagecontainer/#event-show
更新了FIDDLE
var x, y;
$(document).on("pagecreate","#homePage", function(){
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(showPosition);
}
});
$(document).on( "pagecontainershow", function( event, ui ) {
if (ui.toPage.prop("id") == "mapPage"){
makeMap();
}
});
function showPosition(position) {
var positThing = $('#myFooterPosit');
positThing.text('lat: ' + position.coords.latitude + " : " + " long: " + position.coords.longitude);
x = position.coords.latitude;
y = position.coords.longitude;
}
function makeMap() {
try {
var map = new ol.Map({
target: 'map',
layers: [
new ol.layer.Tile({
title: 'OSM',
type: 'base',
visible: true,
source: new ol.source.OSM()
})],
view: new ol.View({
center: ol.proj.transform([y, x], 'EPSG:4326', 'EPSG:3857'),
zoom: 14
})
});
} catch (e) {
alert(e.message);
}
}
