Javascript select onchange='this.form.submit()'

I have a form with a select and a few text inputs. I'd like the form to be submitted when the select is changed. This works fine using the following:

onc开发者_开发知识库hange="this.form.submit()"

However, if the form also contains a submit button, then the form does not submit when the select is changed. I'm guessing some kind of conflict.

What are my options here?

Should I use something like $(this.form).trigger("submit") instead?

You should be able to use something similar to:

$('#selectElementId').change(
    function(){
         $(this).closest('form').trigger('submit');
         /* or:
         $('#formElementId').trigger('submit');
            or:
         $('#formElementId').submit();
         */
    });

My psychic debugging skills tell me that your submit button is named submit.
Therefore, form.submit refers to the button rather than the method.

Rename the button to something else so that form.submit refers to the method again.

If you're using jQuery, it's as simple as this:

 $('#mySelect').change(function()
 {
     $('#myForm').submit();
 });

There are a few ways this can be completed.

Elements know which form they belong to, so you don't need to wrap this in jquery, you can just call this.form which returns the form element. Then you can call submit() on a form element to submit it.

  $('select').on('change', function(e){
    this.form.submit()
  });

Bind them using jQuery and make jQuery handle it: http://jsfiddle.net/ZmxpW/.

$('select').change(function() {
    $(this).parents('form').submit();
});

Use :

<select onchange="myFunction()">

    function myFunction() {
        document.querySelectorAll("input[type=submit]")[0].click();
    }
