Hi,

I would like to know, how can we get the length of an Object using jquery. I have tried using object.length property, but it gives me result as undefined.
Below is my code where i have been able to get the keys and their values, but what i am looking is to get the length of my object.

jQuery.each(c, function(name, value) { 
alert(name + ": " + value); 
});

Any help is appreciated.

Thanks.

0	Hi Nratz83 , As per your query i understand that you are looking to for loop an array or collection..please find the below block of code..may it help you.. Put it in your script block and check.. $(document).ready(function () //this function is needed to display on page load.. { var test = new Array(); //declare an empty array var test = new Array("Ravi", "Ramesh", "Rockesh"); //assign values to it $.each(test, function (i) //for loop an array here i=index of an array { alert(test[i]); }) }); Thanks & Regards, Ravindra M (Success Always Depends on Dedication & Commitment) Nratz83, if this helps please login to Mark As Answer. \| Alert Moderator

0	You can use length to get the length of any array. e.g: new Array("A", "B", "C").length // will give you 3. As you said object, which kind of object it is. Is it a jSON string that you are trying to iterate? In that case, you can use eval() / JSONStringify() to convert the string to jSON and then you can use length property . Hope it will help you :) Nratz83, if this helps please login to Mark As Answer. \| Alert Moderator
