Question

我有2个问题，我希望用户回答，并希望console.log将这些答案放在一起。我已经成功完成了1个问题，但无法弄清楚如何获得2个问题。我知道我还很遥远，但这是我到目前为止的成就。

        var EventType = prompt("What kind of Event are you attending?");
        var tempFahr = prompt("What is the temperature?");

        if( EventType == "semi-formal" ) {
           console.log("Wear a polo ");
        } else if( EventType == "casual" ) {
           console.log("Wear something comfy ");
        } else if( EventType == "formal" ) {
           console.log("Wear a suit");
        } else {
           console.log("Wear nothing!");
        }


        if( tempFahr <= 70 ) {
           console.log("It is hot outside!");
        } else if( tempFahr >= 54 ) {
           console.log("It's chilly outside!");
        } else if( tempFahr < 54 + >70 ) {
           console.log("It is pleasant outside");
        } else {
           console.log("Who cares about the weather,");
        }

有两种方法可以解决此问题，但最简单的方法可能只是将其分配给结果变量。

    var EventType = prompt("What kind of Event are you attending?");
    var tempFahr = prompt("What is the temperature?");

    var recommendedClothing
    if( EventType == "semi-formal" ) {
       recommendedClothing = "Wear a polo ";
    } else if( EventType == "casual" ) {
       recommendedClothing = "Wear something comfy ";
    } else if( EventType == "formal" ) {
       recommendedClothing = "Wear a suit";
    } else {
       recommendedClothing = "Wear nothing!";
    }

    var weatherAssessment
    if( tempFahr <= 70 ) {
       weatherAssessment = "It is hot outside!";
    } else if( tempFahr >= 54 ) {
       weatherAssessment = "It's chilly outside!";
    } else if( tempFahr < 54 || tempFahr > 70 ) {
       weatherAssessment = "It is pleasant outside";
    } else {
       weatherAssessment = "Who cares about the weather,";
    }

    console.log(recommendedClothing + ' ' + weatherAssessment)

修改

其他一些注释，因为看来您可能仍在学习（顺便问一下第一个大问题！）

为变量选择一个一致的大小写（我可能会将EventType重命名为eventType，因此与tempFahr的大小写相同）
54 + >70可能不符合您的期望。查看逻辑运算符，即&&和||

尝试从提示输入console.log 2输入
