Why do all the select boxes require two clicks to open the drop-down menu when the function is activated?

After implementing this code on my webpage, I noticed an issue where all select boxes required two clicks from the user to open the drop-down menu. The first click seemed to set focus on the box, and only on the second click would the drop-down actually appear. When I removed the code, the behavior changed and users were able to open the drop-down with just one click.

I'm not sure what needs to be fixed or modified to prevent this two-click issue, especially since I am using IE 7 and avoiding jQuery as a solution. It seems like there might be a workaround involving CSS focus.

Thank you for any assistance you can provide.


function v9_form() {
    // Function content goes here
}

Answer №1

Internet Explorer has a known issue where it doesn't display dropdown choices if you modify the style using the onfocus event.

An alternative solution is to utilize the onfocusin event for Internet Explorer:

y[i].onfocusin = function() { this.style.backgroundColor = '#FFFFC4'; }

According to MSDN:

This event fires just before setting focus on an element.

Another approach is to employ the :focus CSS selector, though in this case, you are limited to working with CSS alone and cannot implement complex Javascript logic.

Answer №2

Seems like you've run into a problem with this bug.

It appears to be related to some unusual behavior in IE. The linked answer suggests a workaround that may help, although it seems quite bulky for the issue at hand (specifically designed for older versions of IE). Another alternative could be utilizing a CSS pseudo class (as mentioned in the previous answer), or simply removing the feature altogether for users on IE<8.
