通过嵌套对象属性循环

Question

我想检查一个嵌套对象中的空值，我将如何循环通过嵌套的属性？

for (var propt in updatedInputs) { 

    if (updatedInputs[propt] == "") this.cancelSubmit(); 

    // check for nested properties 
    if (updatedInputs.hasOwnProperty(propt)) { 

    // loop through nested properties here 

    } 
} 

样本对象：

Object {contacts: Array[5]} 
    contacts: Array[5] 
    0: "04354355" 
    1: "24349878779" 
    2: "wqewqewqeqw" 
    3: "wqewqeqwe" 
    4: ""

好啊，那我认为它会做你现在想要什么。

function iterObj(obj) { 

    for (var key in obj) { 
    console.log(key + ': ' + obj[key]); 
    if (obj[key] !== null && typeof obj[key] === "object") { 
     // Recurse into children 
     iterObj(obj[key]); 
    } 
    } 
}
