force form submit button click with jquery

Question

Trying to trigger the submit functionality from JQuery. what am I doing wrong? In theory, this should work. I've tried about 4 different ways though.

I have tried

$('input#submit').trigger("click");

$( form:first ).submit();

$( form:first ).trigger("submit");

$('form#databaseActionForm').submit();

NOTHNG HAS WORKED (YET)?!

Answer 1

There are 2 issues here, 1 is a typo in the element name form , you have it as from .

Another is the name/id of the submit button, it should not be submit as it will override the default submit property(the function) of the form element

<input type="submit" id="bsubmit" name="bsubmit" value="submit" style="position: absolute; left: -9999px; width: 1px; height: 1px;" tabindex="-1" />

Then just use the below snippet to submit the form

$('#databaseActionForm').submit();

Demo: Fiddle

Answer 2

I think the problem is you misspelled "form" as "from". Check the syntax highlighting. After that, any of these will work:

$('form#databaseActionForm').submit();

$('#databaseActionForm').submit(); // referencing the form's ID

document.databaseActionForm.submit(); // referencing the form's NAME
