Archive widget has stopped working.

[EXL]

When I choose a month nothing happens.

In previous versions of WordPress, <select> form was filled with the onchange property:

<select id="archives-dropdown-2" name="archive-dropdown" onchange="document.location.href=this.options[this.selectedIndex].value;">

This worked perfectly.

Now JavaScript function is being used, which seems to work incorrect in my WordPress installation:

<script type="text/javascript">
/* <![CDATA[ */
(function() {
	var dropdown = document.getElementById( "archives-dropdown-3" );
	function onSelectChange() {
		if ( dropdown.options[ dropdown.selectedIndex ].value !== '' ) {
			document.location.href = this.options[ this.selectedIndex ].value;
		}
	}
	dropdown.onchange = onSelectChange;
})();
/* ]]> */
</script>

Most likely this bug was introduced in this commit: ​https://github.com/WordPress/WordPress/commit/bba488f2b7fc241b03063fefc58a1db479e977d6#diff-f1b15459db03501d704506f19d778693R107

P.S. I use these settings:

Hi @EXL, welcome to WordPress Trac! Thanks for the report.

Looks like there is a mismatch between archives-dropdown-2 in the older code and archives-dropdown-3 in the newer function, however I could not reproduce the issue on a clean install.

After creating two Archives widgets on the same page (getting archives-dropdown-2 and archives-dropdown-3 ID attributes, respectively), choosing a month in either of them work as expected for me. Tested with the latest stable versions of Google Chrome and Microsoft Edge.

1. Which browser are you using?
2. Could you provide the steps to reproduce the issue on a clean install?
3. Do you have a live page example where the widget doesn't work as expected?
4. Does the similar JS code in the Categories widget​ work for you?

@SergeyBiryukov
I'm sorry. The error was found in my own template.

No worries, thanks for the follow-up.
