如何查看 javascript 中对象内的值是否相同 "line"

Question

不确定如何解决这个问题，但我想看看两个值是否相同 'line'

var inventory_needed = [
    { section: "hardware",          supplies: "hammers"                       },
    { section: "plumbing",          supplies: "pipes"                         },
    { section: "garden",            supplies: "grass seeds"                   },
    { section: "cleaning supplies", supplies: ["hand sanitizer", "detergent"] },
    { section: "appliances",        supplies: ["fridges", "dishwashers"]      } 
];

我想尝试的伪代码

if(section.value && supplies.value in the same line) {
    return true;
}
else {
    return false;
}

//example 1
if("appliances" && "fridges" in the same line) {
    return true; //would return true
}
else {
    return false;
}

//example 2
if("plumbing" && "fridges" in the same line) {
    return true; 
}
else {
    return false; //would return false
}

在同一行中，您的意思似乎是在数组中的同一对象内定义。如果那是正确的，方法是这样的：

function inTheSameLine(section, supplies){
    return inventory_needed.some(obj => {
        return obj.section === section && (
            obj.supplies === supplies || (
               Array.isArray(obj.supplies) && obj.supplies.includes(supplies)
            )
        );
    });
}

JavaScript数组some函数returns如果数组中的任何一个元素满足条件则为真
