在嵌套数组中按键查找

递归是您的朋友。我更新了该函数以说明属性数组：

function getObject(theObject) {    var result = null;    if(theObject instanceof Array) {        for(var i = 0; i < theObject.length; i++) { result = getObject(theObject[i]); if (result) {     break; }}    }    else    {        for(var prop in theObject) { console.log(prop + ': ' + theObject[prop]); if(prop == 'id') {     if(theObject[prop] == 1) {         return theObject;     } } if(theObject[prop] instanceof Object || theObject[prop] instanceof Array) {     result = getObject(theObject[prop]);     if (result) {         break;     } }         }    }    return result;}
