javascript 变量在初始化后未定义

Question

我有下面的代码，它太简单了

var Height = <%= Height %>,
    _height;                       

console.log(Height); // in my test, I got 800

    if(Height > 800){      

        _height = 450;
    }
    else {
       _height = 330;
    }
    console.log(_height); // it will log 'undefined'

什么部分是错误的？

Answer 1

您的拼写错误(缺少字母)

heigh = 450;

所以，尝试下面的代码:

var Height = <%= Height %>,
        _height;                       

    console.log(Height); // in my test, I got 800

        if(Height > 800){      

            _height = 450;
        }
        else {
           _height = 330;
        }
        console.log(_height);
