    return eval("(" + result + ")");
}

function legworkAct() {
    var location = getLocation();
    if (!location) {
        //无法登陆
        return;
    }
    var latlon = location.latitude + "," + location.longitude;
    document.getElementById("latlon").value = latlon;
    document.getElementById("legworkForm").submit();
}

</script>

java代码

<div style="display: none;">
<form id="legworkForm" method="post" action="">
