jQuery access input hidden value

Question

How can I access tag\'s value attribute using jQuery?

Answer 1

Watch out if you want to retrieve a boolean value from a hidden field!

For example:

(An input like this will be rendered by ASP MVC if you use @Html.HiddenFor(m => m.SomeBoolean).)

Then the following will return a string 'False', not a JS boolean!

var notABool = $('#SomeBoolean').val();

If you want to use the boolean for some logic, use the following instead:

var aBool = $('#SomeBoolean').val() === 'True';
if (aBool) { /* ...*/ }
