javascript - 将 Javascript 变量写入 - 无需 onclick

Question

这是最新的

有人知道为什么这不会重定向吗？

 function onGeoSuccess(event)
{
    document.getElementById("Latitude").value =  event.coords.latitude; 
    document.getElementById("Longitude").value = event.coords.longitude;
    document.getElementById("location").href = "track.cfm?track=s&Lat=" + event.coords.latitude + "&Long=" + event.coords.longitude;

var redirectUrl = "track.cfm?track=s&Lat=" + event.coords.latitude + "&Long=" + event.coords.longitude; 

}

function redirect() 
{ 
    window.location.href = redirectUrl; 
} 
setTimeout(redirect,15000); 

我陷入了大脑放屁模式，似乎无法将 javascript 变量写入 A anchor href。有想法吗？我确信我错过了一些简单的东西......

所以 Javascript 正在将 GPS 拉到下面 - 工作正常......

我需要它来将纬度和经度填充到 anchor href...没有“onclick” - 需要自动填充...

所以:

 <a href="page.htm?Lat=javascript(latitude)&Long=javascript(longitude)">GPS Location</a>

 javascript(latitude) - is variable I need to pull from below Javascript
 javascript(longitude) - is variable I need to pull from below Javascript

  <script type="text/javascript"> 
   function getLocationConstant()
{
    if(navigator.geolocation)
    {
        navigator.geolocation.watchPosition(onGeoSuccess,onGeoError);   
    } else {
        alert("Your browser or device doesn't support Geolocation");
    }
}

// If we have a successful location update
function onGeoSuccess(event)
{
    document.getElementById("Latitude").value =  event.coords.latitude; 
    document.getElementById("Longitude").value = event.coords.longitude;

}

// If something has gone wrong with the geolocation request
function onGeoError(event)
{
    alert("Error code " + event.code + ". " + event.message);
}

   </script>

<a href="" id="location">GPS Location</a>

<script>
function onGeoSuccess(event)
{
    document.getElementById("Latitude").value =  event.coords.latitude; 
    document.getElementById("Longitude").value = event.coords.longitude;

    document.getElementById("location").href = "page.htm?Lat=" + event.coords.latitude + "&Long=" + event.coords.longitude;
}
</script>
