我似乎无法获得这些if语句按预期工作.无论我输入"字符串答案",它总是跳转到第一个IF语句,其中条件设置为仅在答案正好为"n"或"N"时执行块或者答案恰好为"y"的块或"Y".如果你输入任何其他内容,它应该返回0.
// Game Recap function, adds/subtracts player total, checks for deposit total and ask for another round
int gameRecap() {

answer.clear();

cout << "The winner of this Game is: " << winner << endl;
cout << "Player 1 now has a total deposit of: " << deposit << " credits remaining!" << endl;

我发布了以下javascript代码作为fiddle.这是非常基本的,在IE11和Chrome中运行良好,但FireFox悄然抛弃了我的float设置.当我使用FireBug检查元素时,它们都没有float设置它们的样式.
为什么？
浏览网页时,我得到的模糊印象是它与width需要设置的地方有关,但在哪里？如果这是问题,我有没有办法在Firefox中执行此操作而不知道容器的宽度？
var titleElem = document.createElement("div");
titleElem.innerHTML = "Testing";
titleElem.setAttribute("unselectable", "on");
titleElem.style.border = "0px transparent";
titleElem.style.width = "auto";
titleElem.style.float = "left";
titleElem.style.whiteSpace = "nowrap";
titleElem.style.overflow = "hidden";
titleElem.style.position = "relative";
document.body.appendChild(titleElem);
rangeElem = document.createElement("div");
rangeElem.setAttribute("unselectable", "on");
rangeElem.style.width = "auto";
rangeElem.style.border = "0px transparent";
rangeElem.style.float = "right";
rangeElem.style.whiteSpace = "nowrap";
rangeElem.style.overflow = "hidden";
rangeElem.style.position = "relative";
rangeElem.style.fontSize = "x-small";
rangeElem.style.paddingRight = "5px";
rangeElem.className = "rangeDiv";
rangeElem.innerHTML = "<i>[1234 - 5678]</i>";
document.body.appendChild(rangeElem);
这是我的代码:
function setActualDate()
{
var d1 = new Date();
var y = d1.getFullYear();
var d = d1.getDate();
var m1 = d1.getMonth() + 1;
var m2 = d1.getMonth();
document.getElementById('entryDate').value = (y+"-"+m1+"-"+d);
document.getElementById('selectedYear').value = y;
document.getElementById('selectedMonth').value = ("0"+m2);
}
</script>
</head>
<body onload="setActualDate()">

请注意，我也在使用轨道控制。
我使用以下代码将相机的位置设置为 x=-2000：
camera.position.x=-2000;
camera.position.z=4000;
当我这样做时，相机会移动位置，但仍然指向 (0,0,0)，导致外观倾斜。所以我假设我需要给它一个向量
camera.up = new THREE.Vector3(0,1,0); //keeps the camera horizontal
camera.lookAt(new THREE.Vector3(2000,0,0)); //should point the camera straight forward
请注意，我仍在尝试找到有关如何设置lookAt 工作的良好解释。
我期待使用if语句来检查e.currentTarget.id是否不等于"alert"或"history",这是行不通的.还有另一种方法可以检查这种情况的两种情况吗？
var buttons = elt.find(":submit,:button,.clickable");
buttons.unbind("click");
buttons.click(function (e) {
put({ "tag": "click", "id": e.currentTarget.id});
if(e.currentTarget.id != "alert" || e.currentTarget.id != "history"){
$(".hide_on_click").hide();
}
});
给定N = A%B,如何找到A%C的值,其中B> C.给出N和C的值,但不给出A.
有没有办法找到这个？
我试图找到用户输入的数字的罪,例如1.5.我已经在计算器上完成了它并且它可以工作,但代码不起作用.
这是代码:
package msd1;
import java.util.Scanner;
public class Part3
{
public static void main(String[] args)
{
Scanner scanner = new Scanner(System.in);
System.out.println("Enter a number");
double Height = scanner.nextDouble();
double Angle = Height/2;
double asine = Math.asin(Angle);
System.out.println("Arcsine of " + Angle + " = " + asine);
}
}
