Wikitude将值从java传递到JavaScript，以便在AR.RelativeLocation中使用它
我将一个整数从java传递到javascript，现在我想使用该值来更改对象的高度 我将a添加到RelativeLocationWikitude将值从java传递到JavaScript，以便在AR.RelativeLocation中使用它,javascript,android,wikitude,Javascript,Android,Wikitude,我将一个整数从java传递到javascript，现在我想使用该值来更改对象的高度 我将a添加到RelativeLocationvar location=新的AR.RelativeLocation（null，8，0，a） 问题是它忽略了我传递的值，即10，并将a作为0。我知道从这个var e=document.getElementById（'loadingMessage'）正确传递的值显示高度：10 Javascript代码： var World = { loaded: false,
var location=新的AR.RelativeLocation（null，8，0，a）

请记住Model.onload是异步的。我的假设是，事情发生的顺序是：init（）->createModelAtLocation（）->java sets altitude->worldLoaded（）
要避免这种情况，您可以采取以下措施：
var World = {
location: null,
...
World.location = new AR.RelativeLocation(null, 8, 0, a);
...
};
function setAltitude(altitude){
World.location.altitudeDelta = altitude;
}

我试过了，但是现在模型和高度都显示不出来了。对于此行World.location.altitudeDelta=海拔我也试过World.location.a=海拔得到了同样的结果。我试过了，但是现在模型和高度都没有显示出来。对于此行World.location.altitudeDelta=海拔我也试过World.location.a=海拔并得到相同的结果。
