为什么这个javascript代码不起作用？ [英] Why this javascript code doesn't work?

问题描述

各位大家好，我正在开发Reversi（奥赛罗）游戏，我遇到了一个场景，我将在板上发现空位，我写了（最后），但这并不准确。



请访问 http://jsfiddle.net/huL3qoa3/ [ ^ ]看到它。



点击在董事会的任何地方，都会显示一个警告，如果该位置是否为空，它运行不正常，有什么问题？



请帮助我。



感谢宝贵的时间。



TIA。

推荐答案

可能是因为你的布尔返回被反转了？我将其更改为以下内容并且能够使其正常工作。我使用术语工作非常宽松，因为我相信你在代码中还有其他一些问题。

probably because you have your boolean returns reversed?? I changed it to the following and was able to get it "working". I am using the term "working" very loose because I believe you have some other problems in the code.

function IsEmpty(x, y) {
    var Temp1 = document.getElementsByTagName("img");
    var i;

    var xx, yy;
    xx = (x * 50) - 50 + ("px");
    yy = (y * 50) - 50 + ("px");

    for (i = 0; i < Temp1.length; i++) {
        if (Temp1[i].style.left != xx && Temp1[i].style.top != yy) {
            Empty = false;
        } else {
            Empty = true;
            break;
        }
    }

    return Empty;
}

我只是通过改变&&到||在以下函数中：

I solved it myself simply by changing && to || in following function:

function IsEmpty(x,y)
{
var Temp1=document.getElementsByTagName("img");
var i;

var xx,yy;
xx=(x*50)-50+("px");
yy=(y*50)-50+("px");

for(i=0;i<Temp1.length;i++)
{

if(Temp1[i].style.left!=xx || Temp1[i].style.top!=yy )
{
Empty=true;
}
else
{
Empty=false;
break;
}


}
