Comments on: jQuery snippet to get all input values /jquery-snippet-to-get-all-input-values/ Web development notes and commentary from Ryan Stille Sun, 28 Oct 2012 15:34:27 +0000 hourly 1 https://wordpress.org/?v=6.1.1 By: Ryan /jquery-snippet-to-get-all-input-values/comment-page-1/#comment-2981 Sun, 28 Oct 2012 15:34:27 +0000 /?p=1121#comment-2981 Interesting suggestion Nathan. I just played with .serialize() a little, and confirmed that you can give it a class. For my use, I need to know if a specific group of fields on the form was filled in. So I tried using this:

var allValues = $("input.someClass").serialize();

The problem is that it returns a string regardless if the fields are filled in or not. So I don’t see an easy way to use this to determine if the fields were filled in.

Update: Ah, I just thought of a way this could be used. I could find out the length of a serialized empty form, then compare that, like:


var emptyLength = 56; // determined when the form was built
var allValues = $("input.someClass").serialize();
if (allValues.length > emptyLength) {
// then I know the fields were filled in
}

I mean, your method is good too, just seems like it does a lot more than it needs.
