How can I select a hidden field by value?

Answer 1

$('input:hidden[value=\'3\']');

Answer 2

Using jQuery Selectors, you can target your element by a certain attribute matching the desired value:

$('input[value="Whatever"]');

This way you are targeting an input element, by the attribute value that is equal to the desired value.

EDIT 5/14/2013: According to an answer below, this no longer works as of jQuery 1.9.

Answer 3

Note: Since jQuery 1.9 the input[value="banana"] selector is no longer valid, because 'value' of the input is technically not an attribute. You need to use the (far more difficult to read) .filter

E.g.

$("input").filter(function () {
    return this.value === "banana";
});
