我正在尝试遍历数组对象。我想只返回整个对象，只有匹配类型的记录与我输入的字符串匹配＆＃39;类型＆＃39;当密钥匹配我在函数中传递的密钥时键入对象，在这种情况下是函数计费。我在react中编写一个javascript函数，它接受一个数组和字符串作为参数。 我无法正确匹配密钥。
如果str是＆＃39; Billing＆＃39;，则应返回所有类型为Billing的记录。
getAddress(arrayObj, str) {
for(let add in arrayObj) {
if(arrayObj[add].type === str) {
return arrayObj[add];
}
return null;
}
}
let billAddress = this.getAddress(this.address, 'Billing');
这是我的数组对象：
this.address=[

答案 0 :(得分：4)
如果我理解正确，这对于数组的.filter方法来说是个好例子。只需传入一个函数，当字符串符合您的要求时返回true，如下所示：
getAddress(arrayObj, str) {
return arrayObj.filter(x => x.type === str);
}
或者，如果您只想找到第一场比赛而不是所有比赛，那么您可以使用.find代替：
// This version returns either the first object that matches the type,
// or undefined if there were no matches.
getAddress(arrayObj, str) {
return arrayObj.find(x => x.type === str);
}
请参阅此代码段以获取示例：

您的原始功能具有正确的概念。但是你在第一场比赛后不应该回来，对吗？这是else if (donorGender != "Male" && donorGender != "Female" && donorGender != "Trans Male" && donorGender != "Trans Female" && donorGender != "Queer" && donorGender != "Different")
的作用。你正在寻找一个数组，所以<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFrameworks>netstandard1.4;net40;net45</TargetFrameworks>
</PropertyGroup>
中的元素然后返回那个数组。
return也是一个不错的选择。在我看来，更好，因为它是更清晰的代码。
Array#push
