多个 OR 字符串 [英] Multiple OR Strings

问题描述

我不知道如何在 If 语句中传递多个字符串.

I cannot find out how to pass multiple strings in an If statement.

这是我的代码:

    var date = new Date();

    if (document.getElementById("postcode-entry").value == ("G74" || "G75")) {
        if (date.getHours() < 8 ) {
            window.alert("Sorry we are not open at the moment, please try again later.");
        } else {
            window.open("http://http://stackoverflow.com");
        }
    } else {
        window.alert("Sorry we do not Delivery to your area, please collect from store");
    }

我该怎么做?

推荐答案

短语 ("G74" || "G75") 强制对每个字符串进行布尔计算，并且两者都将始终返回 true.

The phrase ("G74" || "G75") forces a boolean evaluation on each string, and both will return true always.

所以你需要做这样的事情:

So you would need to do something like this:

var myvar = document.getElementById("postcode-entry").value;

if(myvar === "G74" || myvar === "G75")
