点击链接后我需要在bootstrap 3模式框中加载谷歌地图.js api并使用谷歌地图初始化方法打开模态框:
HTML:
<input id="lat" class="text-input form-control" type="text" size="24" name="lat">
<input id="lon" class="text-input form-control" type="text" size="24" name="lon">
<a data-toggle="modal" href="#myModal" class="btn btn-primary">Launch modal</a>
<div class="modal" id="myModal">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title">Modal title</h4>
</div>
<div class="modal-body">Location:
<input type="text" id="us2-address" style="width: 200px" />Radius:
<input type="text" id="us2-radius" />
<div id="us2" style="height: 400px;"></div>Lat.:
<input type="text" id="us2-lat" />Long.:
<input type="text" id="us2-lon" />
</div>
<div class="modal-footer"> <a href="#" data-dismiss="modal" class="btn">Close</a> <a href="#" class="btn btn-primary" id="save-changes">Save changes</a>
</div>
</div>
</div>
</div>
JS:
var stillPresent = false;
function initialize() {
if (stillPresent == false) {
$('#us2').locationpicker({
location: {
latitude: 46.15242437752303,
longitude: 2.7470703125
},
radius: 300,
inputBinding: {
latitudeInput: $('#us2-lat'),
longitudeInput: $('#us2-lon'),
radiusInput: $('#us2-radius'),
locationNameInput: $('#us2-address')
}
});
stillPresent = true;
$("#save-changes").click(function() {
$("#lat").val($('#us2-lat').val());
$("#lon").val($('#us2-lon').val());
$('#myModal').modal('hide');
});
}
}
function loadScript() {
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = 'http://maps.google.com/maps/api/js?sensor=false&libraries=places&callback=initialize';
document.body.appendChild(script);
}
$(function () {
$('#myModal').on('shown.bs.modal', function (e) {
loadScript();
});
})
在modalbox中点击保存更改后,我添加了两个用于保存经度和纬度的输入。在第一次location picker工作正常,但点击保存更改后返回到模态框位置选择器不起作用,拖动长和拉不改变 !!
如何解决这个问题?!

答案 0 :(得分:2)
因为您每次显示模式时都在调用loadScript
,所以每次都会包含Google Maps API。这将在您的网页上产生不可预测的结果。
您需要做的是包括Google Maps API一次(使用标记以避免多次加载),然后在显示Bootstrap模式时调整Google Map的大小。
使用这个问题的答案: Showing a Google Map in a modal created with Twitter Bootstrap
然后,您可以使用此代码执行所需操作:
var googleMapsLoaded = false;
function loadScript() {
if (!googleMapsLoaded) {
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = 'http://maps.google.com/maps/api/js?sensor=false&libraries=places&callback=initialize';
document.body.appendChild(script);
googleMapsLoaded = true;
}
}
$(function() {
$('#myModal').on('shown.bs.modal', function (e) {
loadScript();
var map = $('#us2').locationpicker('map').map;
var currentCenter = map.getCenter();
google.maps.event.trigger(map, "resize");
map.setCenter(currentCenter);
});
});
