Does a form reset button fire a select elements onChange event?

问题

I have a form with some select elements that have onChange events attached to them. I would like the event to fire even when someone clicks the form reset button.

My question is: does resetting a form fire a select elements onChange event?

Here is a simple example in jQuery

<script type="text/javascript">
    $('.myselect').change(function() {
        // do something on change
    });
</script>

<form action="/" method="post">
    <select class="myselect" name="select1">
        <option value="1">First</option>
        <option value="2">Second</option>
    </select>
    <select class="myselect" name="select2">
        <option value="1">First</option>
        <option value="2">Second</option>
    </select>
    <!-- When this is clicked I would like it fire the change event -->
    <input type="reset" value="Reset" /> 
    <input type="submit" value="Save" />
</form>

Thanks!

There is an onReset tag for forms, so you could do something like:

<script type="text/javascript">
    var changeFunc = function() {
        // do something on change.
    };
    $('.myselect').change(changeFunc);
</script>

<form onReset="changeFunc()" action="/" method="post">
    <select class="myselect" name="select1">
        <option value="1">First</option>
        <option value="2">Second</option>
    </select>
    <select class="myselect" name="select2">
        <option value="1">First</option>
        <option value="2">Second</option>
    </select>
    <!-- When this is clicked I would like it fire the change event -->
    <input type="reset" value="Reset" /> 
    <input type="submit" value="Save" />
</form>

This method is called before the reset happens, though so it can be tricky. I guess so you can do an "Are you sure?" box. Tossing a setTimeout in the reset function seems to do the trick.

Jack M.'s answer is working good. Here is another approach for doing the same. Hope it will help somebody.

Write code/events which you wanted to call in middle of this function. I have tested this. Working good.

$(document).ready(function() {
    $("input:reset").click(function() {       // apply to reset button's click event
        this.form.reset();                    // reset the form

        // call your functions to be executed after the reset      

         return false;                         // prevent reset button from resetting again
    });
});
