百度地图第一次加载错位，拖动地图后地图标注显示正确。

部分代码如下：

jQuery(document).ready(function () {

var whpSession = $.parseJSON(getCookie("whpSession")); //获取session

if (whpSession == "" || whpSession == null) {
alert("请先登录!");
window.location.href = "../../login.html";
} else {
if (mylx == "gl") { $('#username').text(whpSession["UserName"]); } else {
$('#username').text(whpSession["企业名称"]);
}
}
App.init();
$('.page-container').css("height", $(window).height() - 42 - 35);
$('#allmap').css("height", $(window).height() - 42 - 35 - 255 - 85);
$("#tooslsHeight").click(function () {
if ($(this).hasClass("collapse")) {
$('#allmap').height(function (n, c) {
return c + 190;
});
} else {
$('#allmap').height(function (n, c) {
return c - 190;
});
}
});

addMarker(point, k, v); //添加标注
map.centerAndZoom(point, 20);
// map.setViewport(ply.getPath()); //调整视野
});
}
else {
alert("无标注信息!");
}
});

});
