我的html文档中有两个脚本，一个是外部脚本，一个是内部脚本。我想将它们组合到一个外部javascript文件中。不幸的是，当我将内部脚本放在外部脚本中时，内部脚本功能似乎不起作用。我不明白为什么不会。
下面的组合脚本分为内部和外部内容。
//INTERNAL SCRIPT
var x = 0, y = 0,
vx = 0, vy = 0,
ax = 0, ay = 0;
var points;
var sphere = document.getElementById("sphere");
var counting = false;
var counter = 0;
var numberOne;
if (window.DeviceMotionEvent != undefined) {
window.ondevicemotion = function(e) {
ax = event.accelerationIncludingGravity.x * 5;
ay = event.accelerationIncludingGravity.y * 5;
document.getElementById("counterSpan").innerHTML = Math.round(counter*10)/10;
//document.getElementById("accelerationX").innerHTML = Math.round(e.accelerationIncludingGravity.x * 10)/10;
//document.getElementById("accelerationY").innerHTML = Math.round(e.accelerationIncludingGravity.y * 10)/10;
//document.getElementById("accelerationZ").innerHTML = Math.round(e.accelerationIncludingGravity.z * 10)/10;
var moveX = Math.round(e.accelerationIncludingGravity.x * 10)/10;
//var moveY = Math.round(e.accelerationIncludingGravity.y * 10)/10;
//var moveZ = Math.round(e.accelerationIncludingGravity.z * 10)/10;
if(moveX > 5 || moveX < -5) {
counting = true;
//alert(counting);
if(counter < 100){counter+=0.01;}
}
if ( e.rotationRate ) {
//document.getElementById("rotationAlpha").innerHTML = Math.round(e.rotationRate.alpha * 10)/10;
//document.getElementById("rotationBeta").innerHTML = Math.round(e.rotationRate.beta * 10)/10;
//document.getElementById("rotationGamma").innerHTML = Math.round(e.rotationRate.gamma * 10)/10;
}
}
$( "#btnEnergize" ).click(function() {
numberOne = $("#numberOne").val();
alert(numberOne);
localStorage.setItem('points',numberOne);
if (numberOne <= counter){
counter-=numberOne;
}
else {
alert("Not enough Energize points");
}
});
setInterval( function() {
var landscapeOrientation = window.innerWidth/window.innerHeight > 1;
if ( landscapeOrientation) {
vx = vx + ay;

如果你看一下你的外部代码，它就是一个简写的jQuery ready事件处理程序。由于您的内部代码与DOM交互，因此您应该确保它也在相同的事件处理程序上下文中运行。
可能您的内部代码位于页面底部的onload函数内，或者可能位于其自己的ready事件处理程序中，您忘记将其考虑在内。
