Question

客户要求我在此处重新设置Flash模块：http://www.bendelcorp.com/toolscalculators.html

除压力/真空计算外，一切正常。如果单击该选项卡并在psi字段中输入一个数字，然后单击“计算”，则会使用NaN（不是数字）填充所有字段。

以下是旧版ActionScript：

on (release, keyPress "<Enter>") {
gotoAndStop("pressure/vacuum", 5);
if (inchofwater != "") {
    inchofwaterResult = Number(inchofwater);
    psiResult = Number(inchofwater)*0.03609119066;
    inchofmercuryResult = Number(inchofwater)*0.07348242091;
    barResult = Number(inchofwater)*0.0024884;
    milimeterofmercuryResult = Number(inchofwater)*1.866453491;
    torrResult = Number(inchofwater)*1.866453491;
    meterofwaterResult = Number(inchofwater)*.02537461824;
}

}
}

我会在这里感谢一些帮助。

感谢。

Answer 1

if (inchofwater != "")

所有这一切都是测试，如果inchofwater是一个空字符串，而不是它是否计算为数字。数字（“a”）不是空字符串，但毕竟它 NaN。在尝试将其作为字符串转换之前，inchofwater的值是多少？

同样，您在投入的其他原始值是什么，因为您认为用户输入符合您的期望？

Answer 2

问题在于计算。列出了一些没有相应字段的元素，并且在运行计算之前未将值设置为0，因此我在页面加载时添加了重置，然后正确计算了内容。

为什么闪存计算会导致NaN？
