Question

This is trivial I know but I’m so used to OOP languages. I’m trying to figure out how to write out each name/value in either one alert or many, just so I can verify the data

var dCookieNameValuePairs = {};

for (i = 0; i < cookieValues.length; i++)
{
    var akeyValuePair = aCookieValues[i].split("=");
    dCookieNameValuePairs[keyValuePair[0]] = keyValuePair[1];
}

// display each name value pair testing
for (i = 0; i < dCookieNameValuePairs.length; i++)
{
    alert("Name: " + dCookieNameValuePairs[] + "Value: " + 
}

I’m stuck at the second for loop…I am not sure how to iterate through the dictionary and then focus on each name/value to spit it back.

Answer 1

You want to use for..in for enumerating through a dictionary/map.

for ( var prop in dCookieNameValuePairs ) {
   if ( dCookieNameValuePairs.hasOwnProperty( prop ) ) {
       alert( dCookieNameValuePairs[prop] )
   }
}

I may have typo’d. Only use .length when you are dealing with an array [] or a custom array-like object that you defined to have .length populated.
