Get attribute value of hidden form element

Question

I´m using Postman to automate some tests. I need to get the value of the value attribute on the hidden field with the name "execution":

<form class="app-form" method="post" id="fm1" action="login" _lpchecked="1">
    <input type="hidden" name="execution" value="633ffc0f">
</form>

In postman, there´s only cheerio available for this. I´ve tried variations of the following, but none is working:

$('input#execution').attr("value");
$('input[name=execution]').attr("value");
$('input[type=hidden]').attr("value");
$(':hidden#execution').attr("value");
$('input:hidden[name=execution]').attr("value");

Many thanks!

Answer 1

input[name=execution] does work fine for me

console.log($('input[type=hidden]').attr("value"));
console.log($('input[type=hidden]').val());

<form class="app-form" method="post" id="fm1" action="login" _lpchecked="1">
    <input type="hidden" name="execution" value="633ffc0f">
</form>

Answer 2

This is how you get value

const executionValue = $('input[name="execution"]').val();
console.log(executionValue);
