Question

I am trying to figure out how I can get a property value from a jsonObject by giving a property name

well, let’s say I have the object

var jsonObj = eval('{"key1":"value1","key2":"value2"}');

and I want to get a value by using a method

function getPropertyValue(key){
 return jsonObj.key;
}

alert(getPropertyValue("key1"));

I know that I can get the value by using jsonObj.Key but I want to do it by use a method

Is it possible?

For one: Parse your JSON using the correct methods and avoid using eval:

var jsonObj = JSON.parse( '[{"key1":"value1","key2":"value2"}]' );

And your method can look like this:

function getPropertyValue(key){
 return jsonObj[ key ];
}
