How to put a bind-value and an onchange in the same input checkbox?

how to put a bind-value and an onchange in the same input checkbox? The attribute 'onchange' is used two or more times for this element. Attributes must be unique (case-insensitive). The attribute 'onchange' is used by the '@bind' directive attribute. First off, you usually don't bind to the value attribute.

What is checkbox's value in HTML input element?

(Only the HTMLInputElement ’s checked IDL attribute is updated.) Note: Unlike other input controls, a checkboxes value is only included in the submitted data if the checkbox is currently checked. If it is, then the value of the checkbox's value attribute is reported as the input's value.

How to reference the checkbox by its ID?

Reference the checkbox by it's id and not with the # Assign the function to the onclick attribute rather than using the change attribute var checkbox = $ ("save_" + fieldName); checkbox.onclick = function (event) { var checkbox =; if (checkbox.checked) { //Checkbox has been checked } else { //Checkbox has been unchecked } };

Why do I have to click on a checkbox?

This is because if the checkbox has focus, clicking the label takes the focus away from it, firing the change event with the old value, and then the click happens setting the new value and setting focus back on the checkbox. Very confusing. But you can avoid all of that unpleasantness if you use click instead.
