javascript - jQuery's val() is not working on a hidden field -


i have hidden field in page so:

<hidden id="tsdayschedule01" value="7.50"></hidden>

when try access following code, alert returns blank: 

alert($("#tsdayschedule01").val());

now when use attr("value") below, works without issue: 

alert($("#tsdayschedule01").attr("value"));

lastly, point out have other non-hidden text fields within page work without issue using val().

i have better understanding going on here. have explanation?

<hidden/> isn't valid html element. if you're wanting hidden input you'd use:

<input type="hidden" />

jquery's .val() method works on input, select , textarea elements. work you, change <hidden/> element to:

<input type="hidden" id="tsdayschedule01" value="7.50" />
