语法错误已修复。Dreamweaver 说我在第 52 行的代码中有错误。我看不出有什么问题?也许这与我的 if 和 else 语句不起作用这一事实有关。
IF 和 ELSE 语句已修复。如果我单独测试 if 和 else 语句,它们可以正常工作,但是当我运行整个文档时,它们不会运行。有人可以告诉我错误和我的 if/else 语句不起作用是否相关,或者是否还有其他问题。
<script>
var car1=new Object();
car1.Name="Rusty";
car1.Speed="1px", 40;
car1.Distance=0;
var car2=new Object();
car2.Name="Dusty";
car2.Speed="2px", 40;
car2.Distance=0;
var car3=new Object();
car3.Name="Crankshaft";
car3.Speed="4px", 40;
car3.Distance=0;
function runRusty(){
setInterval(function(){moveRusty()},40);
function moveRusty(){car1.Distance=car1.Distance +1
document.getElementById("rusty").style.marginLeft=car1.Distance + "px"
};
};
function runDusty(){
setInterval(function(){moveDusty()},40);
function moveDusty(){car2.Distance=car2.Distance +1
document.getElementById("dusty").style.marginLeft=car2.Distance + "px"
};
};
function runCrankshaft(){
setInterval(function(){moveCrank()},40);
function moveCrank(){car3.Distance=car3.Distance +1
document.getElementById("crankshaft").style.marginLeft=car3.Distance + "px"
};
};
function winLose () {if (document.getElementById("rusty").style.marginLeft="900px"){
alert("Winner is Rusty!");
clearInterval(runRusty);
}
else if(document.getElementById("dusty").style.marginLeft="900px"){
alert("Winner is Dusty!");
clearInterval(runDusty);
}
else if(document.getElementById("crankshaft").style.marginLeft="900px"){
alert("Winner is Crankshaft!");
clearInterval(runCrankshaft);
};
};
</script>
编辑:
if 和 else 语句现在可以工作,因为我更改了全局声明我的函数并稍微更改了它们。代码现在看起来像这样:
var car1=new Object();
car1.Name="Rusty";
car1.Speed=1;
car1.Distance=0;
var car2=new Object();
car2.Name="Dusty";
car2.Speed=2;
car2.Distance=0;
var car3=new Object();
car3.Name="Crankshaft";
car3.Speed=4;
car3.Distance=0;
var moveRusty;
var moveDusty;
var moveCrankShaft;
function runRusty(){
moveRusty=setInterval(function(){
car1.Distance=car1.Distance + car1.Speed;
document.getElementById("rusty").style.marginLeft=car1.Distance + "px";
winLose();
},40);
};
function runDusty(){
moveDusty=setInterval(function(){
car2.Distance=car2.Distance + car2.Speed;
document.getElementById("dusty").style.marginLeft=car2.Distance + "px";
winLose();
},40);
};
function runCrankshaft(){
moveCrankShaft=setInterval(function(){
car3.Distance=car3.Distance + car3.Speed;
document.getElementById("crankshaft").style.marginLeft=car3.Distance + "px";
winLose();
},40);
}
function winLose () {
if (car1.Distance >= 900){
alert("Winner is Rusty!");
car1.Distance = 0;
car1.Speed = 0;
car2.Distance = 0;
car2.Speed = 0;
car3.Distance = 0;
car3.Speed = 0;
}
else
if(car2.Distance >= 900){
alert("Winner is Dusty!");
car1.Distance = 0;
car1.Speed = 0;
car2.Distance = 0;
car2.Speed = 0;
car3.Distance = 0;
car3.Speed = 0;
}
else
if(car3.Distance >= 900){
alert("Winner is Crankshaft!");
car1.Distance = 0;
car1.Speed = 0;
car2.Distance = 0;
car2.Speed = 0;
car3.Distance = 0;
car3.Speed = 0;
}
};
clearInterval(moveRusty);
clearInterval(moveDusty);
clearInterval(moveCrankShaft);
现在一切正常。所有警报都会发生,并且汽车的位置会被重置。但是我所有的 clearInterval() 都不起作用。我不知道 clearInterval() 是否正确使用。我想要做的是重置页面,以便我可以再次运行“游戏”。现在,唯一的方法是刷新页面。我已经仔细检查了我是如何声明我的 setInterval() 以及我如何在我的 clearInterval() 中调用它们的,就我而言,这是对的吗?
