How to get individual values of a variable while using foreach in jquery

Question

I have used a function in jquery that gets all the values from the server side and then on the basis of these values, perform some validations client side. Below is the code that I have used

AOT.View.AssetMarkTrustTrust.prototype.validateSubmit = function () {    
var result = false;
var message = '';
result = applicationView.GetCardEmbossings();//this method will get the values from the server side

if (result != null)
    $.each(result, function () {
        if ((result.CardEmbossingLine1.Length > 26) ||
                   (!string.IsNullOrEmpty(result.CardEmbossingLine2) && result.CardEmbossingLine2.Length > 26) && !result.Suppress) {
            AOT.Utility.displayWarning("Please use Card/Check Editor to specify name that will be printed on card, 26 characters max.");
            return false;
        }
    });

if (!result && !AOT.Utility.isNullEmptyUndefined(message)) {
    AOT.Utility.displayWarning(message, '');
}
return result;

};

Problem is that when I check the length of the value CardEmbossingLine1, it shows as undefined. But, there are values under the object result. I cannot fulfil the condition as different values under the object are undefined due to which the condition is not getting fired. Please let me know where am I missing.

Thanks

put a console.log after the code : result = applicationView.GetCardEmbossings(); and analyze the structure of the object — Rahul Gupta, Jun 09 '14 at 09:49
`applicationView.GetCardEmbossings();` is this making an ajax call? — Abhitalks, Jun 09 '14 at 09:50

Try $.each(result, function (index, item) { if ((item.CardEmbossingLine1.Length... — , Jun 09 '14 at 09:56

The function in "each" can take 2 parameters which is set when jquery iterates thru ur result object.See code below

if (result != null)
$.each(result, function (index,eachResult) {
    if ((eachResult.CardEmbossingLine1.Length > 26) ||
               (!string.IsNullOrEmpty(eachResult.CardEmbossingLine2) && eachResult.CardEmbossingLine2.Length > 26) && !eachResult.Suppress) {
        AOT.Utility.displayWarning("Please use Card/Check Editor to specify name that will be printed on card, 26 characters max.");
        return false;
    }
});
