Array object in jQuery

Question

I have array object in jquery.

array=[];
array{Id:user.Id,Date:user.Date};

Now am going to pass this array object to my handler file which have n number of users. In success function now am going to change the Date for the array only for the particular user. For that i have to find whether array has the user, if yes i have to change the date. So,

if (jQuery.inArray(user.Id, array)) {
// code have to done
}

If my above code is right, Can anyone tell me how to change the date value of the user or tell me any-other simplified way?

Answer 1

jQuery.inArray() won't find the item in this way.

I recommend to use jQuery.each() instead, because unfortunately jQuery does not provide a find function for arrays.

jQuery.each(array, function(index, data) {
 if (data.Id === user.Id) {
 data.Date = newDate;
 return false; // this stops the each
 }
});

Using this method: jQuery.inArray("Q", arrData); You can get the index of you object in array. After that get the object from index and update it.
