Determine if an object hierarchy possesses a specified attribute

When passing a set of options as an object like this:

var options={
    sortRules:[
        {...}, // rule 1
        {...}, // rule 2
        // etc.
    ],
    filterRules:[
        {...}, // rule 1
        {...}, // rule 2
        // etc.
    ],
    etc.
};

The main issue at hand is determining the most efficient way to check if any rule within the object hierarchy contains an "encodedName" property. If such a property exists, I need to promptly retrieve a dictionary of codes via a Web service. However, if no "encodedName" property is present, then the dictionary is unnecessary.

Is there a faster method than looping through all objects and sub-objects in search of the "encodedName" property? One alternative idea could involve using JSON.stringify to convert the object into a string and then utilizing indexOf to look for the specific "encodedName" string. Would this approach be more efficient than iterating through sub-objects?

Answer №1

To address this situation, I propose implementing two different rule sets: one including the encodedName property and one without. By analyzing the category associated with each rule, you can determine if the specific property is included or not.

Another approach would be to utilize a recursive function that systematically searches through all properties to uncover the desired property.

Answer №2

To solve this problem, you can loop through the options object and then check each of its properties (sortRules, filterRules) to see if it contains the desired property.

for(var key in options){
    if(options[key].hasOwnProperty("name"){...}
}

This should handle it effectively.

I also discovered that each rules property is an array, so the best approach is to iterate through it.
