Set value of hidden field in a form using jQuery's ".val()" doesn't work

Question

:text will fail for a input with a type value of hidden. It's also much more efficient to just use:

$("#texens").val("tinkumaster");

ID attributes should be unique on a web page, make sure yours are as this may contribute to any problems you're having, and specifying a more complicated selector just slows things down and doesn't look as neat.

Example at http://jsbin.com/elovo/edit, using your example code at http://jsbin.com/elovo/2/edit

If you're having trouble setting the value of a hidden field because you're passing an ID to it, this is the solution:

Instead of $("#hidden_field_id").val(id) just do $("input[id=hidden_field_id]").val(id). Not sure what the difference is, but it works.

Finally, I have found a solution and it's a simple one:

document.getElementById("texens").value = "tinkumaster";

Works like a charm. No clue why jQuery does not fall back to this.

I had same problem. oddly enough google chrome and possibly others (not sure) did not like

$("#thing").val(0);

input type="hidden" id="thing" name="thing" value="1" />

(no change)

$("#thing").val("0");

input type="hidden" id="thing" name="thing" value="1" />

(no change)

but this works!!!!

$("#thing").val("no");

input type="hidden" id="thing" name="thing" value="no" />

CHANGES!!

$("#thing").val("yes");

input type="hidden" id="thing" name="thing" value="yes" />

CHANGES!!

must be a "string thing"

$('input[name=hidden_field_name]').val('newVal');

worked for me, when neither

$('input[id=hidden_field_id]').val('newVal');

nor

$('#hidden_field_id').val('newVal');

did.
