Temporary code implemented for IE8 is causing the dropdown login field to lose focus

I have encountered an issue with my code in IE8. Whenever I move the mouse around in the dropdown login field, it loses focus and disappears about 70% of the time. After debugging, I discovered that this problem is related to a certain placeholder code:

Update: Interestingly, the problem persists across various placeholder plugins I've tried. Removing these plugins resolves the issue.

$(document).ready(function() {

    if ( !("placeholder" in document.createElement("input")) ) {
        $("input[placeholder], textarea[placeholder]").each(function() {
            var val = $(this).attr("placeholder");
            if ( this.value == "" ) {
                this.value = val;
            }
            $(this).focus(function() {
                if ( this.value == val ) {
                    this.value = "";
                }
            }).blur(function() {
                if ( $.trim(this.value) == "" ) {
                    this.value = val;
                }
            })
        });

        // Clear default placeholder values on form submit
        $('form').submit(function() {
            $(this).find("input[placeholder], textarea[placeholder]").each(function() {
                if ( this.value == $(this).attr("placeholder") ) {
                    this.value = "";
                }
            });
        });
    }

});

Answer №1

Have you considered modifying your event handling to use 'mouseenter' and 'mouseleave' for the dropdown instead of 'focus' and 'blur'? This approach tends to be more consistent on older versions of Internet Explorer. It's also recommended to attach the event directly to the 'dropdown' div rather than the 'input' element.

To implement these changes, you can update your code as follows:

$(function() {
    var dropdown = $('div.login div.dropdown')
        .on('mouseenter', function() {
            dropdown.css('display', 'block');
        })
        .on('mouseleave', function() {
            dropdown.removeAttr('style');
        });
});

Example:

$(function(){
    $('#main_header .login li').hover(function(){
        $(this).find('.dropdown').show();
    },function(){
        $(this).find('.dropdown').hide();
    });
});

Please Note: I have also tidied up and corrected some coding issues in your JavaScript code...

This script is used to add a placeholder feature across all browsers by leveraging Modernizr for detection:

Check out the Demo here: http://jsfiddle.net/4D7Gt/

var placeholderOnBlur = function () {
    var input = $(this);

    if (input.val() == '' || input.val() == input.attr('placeholder')) {
        input.addClass('placeholder');
        input.val(input.attr('placeholder'));
    }
};

var placeholderOnFocus = function () {
    var input = $(this);

    if (input.val() == input.attr('placeholder')) {
        input.val('');
        input.removeClass('placeholder');
    }
};

var placeholderOnSubmit = function () {
    $(this).find('[placeholder]').each(function () {
        var input = $(this);

        if (input.val() == input.attr('placeholder')) {
            input.val('');
        }
    });
};

var placeholderOnLoad = function () {
    if (!!$(this).attr('placeholder')) {
        $(this).on('focus', placeholderOnFocus);
        $(this).on('blur', placeholderOnBlur);
        $(this).parents('form').on('submit', placeholderOnSubmit);
        $(this).blur();
    }
};

 if (!Modernizr.input.placeholder) {
     $('[placeholder]').each(placeholderOnLoad);
 }

I haven't been able to test it on IE8, but theoretically it should function correctly.
