我试图遍历数组对象。我只想返回整个对象，其中记录的类型与我输入的字符串相匹配，如果它与对象中的“type”键相匹配，那么当键与我在函数中传递的键相匹配时（在本例中为billing）。我正在react中编写一个javascript函数，它以数组和字符串作为参数。 我无法正确匹配钥匙 如果str为“Billing”，则应返回类型为Billing的所有记录遍历数组对象Javascript,javascript,arrays,reactjs,Javascript,Arrays,Reactjs,我试图遍历数组对象。我只想返回整个对象，其中记录的类型与我输入的字符串相匹配，如果它与对象中的“type”键相匹配，那么当键与我在函数中传递的键相匹配时（在本例中为billing）。我正在react中编写一个javascript函数，它以数组和字符串作为参数。 我无法正确匹配钥匙 如果str为“Billing”，则应返回类型为Billing的所有记录 getAddress(arrayObj, str) { for(let add in arrayObj) {

如果我理解正确，这将是数组的
.filtergetAddress(arrayObj, str) {
return arrayObj.filter(x => x.type === str);
}
。查找：
// 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);
}
