我在这里看到了这个脚本,它完全符合我的需要,我正在构建一个 Jquery 移动网站,我想要的是只在单击按钮时才显示地图
我发现很难上班。
var map,
currentPosition,
directionsDisplay,
directionsService,
destinationLatitude = latt,
destinationLongitude = lonn;
function initializeMapAndCalculateRoute(lat, lon)
{
directionsDisplay = new google.maps.DirectionsRenderer();
directionsService = new google.maps.DirectionsService();
currentPosition = new google.maps.LatLng(lat, lon);
map = new google.maps.Map(document.getElementById('map_canvas'), {
zoom: 25,
center: currentPosition,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
directionsDisplay.setMap(map);
var currentPositionMarker = new google.maps.Marker({
position: currentPosition,
map: map,
title: "Current position"
});
// calculate Route
calculateRoute();
}
function locError(error) {
// the current position could not be located
}
function locSuccess(position) {
// initialize map with current position and calculate the route
initializeMapAndCalculateRoute(position.coords.latitude, position.coords.longitude);
}
function calculateRoute() {
var targetDestination = new google.maps.LatLng(destinationLatitude, destinationLongitude);
if (currentPosition != '' && targetDestination != '') {
var request = {
origin: currentPosition,
destination: targetDestination,
travelMode: google.maps.DirectionsTravelMode["DRIVING"]
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setPanel(document.getElementById("directions"));
directionsDisplay.setDirections(response);
/*
var myRoute = response.routes[0].legs[0];
for (var i = 0; i < myRoute.steps.length; i++) {
alert(myRoute.steps[i].instructions);
}
*/
$("#results").show();
}
else {
$("#results").hide();
}
});
}
else {
$("#results").hide();
}
}
$(document).live("pagebeforeshow", "#detailPage", function() {
// find current position and on success initialize map and calculate the route
navigator.geolocation.getCurrentPosition(locSuccess, locError);
});
我将它包装在一个单击事件中,当我单击时没有任何反应,浏览器控制台报告 - 未捕获类型错误:对象 #map-button 没有方法“单击”
('#map-button').click(function(){
// Code for map goes here
});
的HTML
<div data-role="page" id="detailPage">
<div data-role="header">
<h1>Detail Page</h1>
</div>
<div data-role="content">
<div id="itemDetails"></div>
<button id="map-button">Get Direction</button>
</div>
<div id="map_canvas" style="height:300px; width:100%"></div>
<div id="results" style="display:none;">
<div id="directions"></div>
</div>
<div data-role="footer">
<h4>Footer</h4>
</div>
</div>
我只希望在单击按钮后显示地图。任何帮助将不胜感激。
