    Problem with $('button').focus()

    I have this extremely simple JQuery function that's not working and I can't figure what I'm doing wrong.

    The code is
    Code:
    	$("button").focus(function(){
    //		$("div#errdisplay").html('');
    		alert("focus");
    		});
    The "alert" is never executed. I've tried "click" and "blur" also.

    Greatly appreciate any help I can get. Thank you.

    The complete routine is

    Code:
    <?php
    require_once("../externals/php/functions.php");
    
    $Title = 'Add Marriage Records';
    
    require("../topmenu.php");
    $HOME = "../{$_SESSION['home']}";
    $BIRTHHOME = "../{$_SESSION['birth']}";
    $MARRIAGEHOME = "../{$_SESSION['marriage']}";
    $DEATHHOME = "../{$_SESSION['obituary']}";
    $HELP = "../{$_SESSION['help']}";
    	
    $Menu = "../menu.php";
    $eMessage="";
    if(isset($_GET['return'])) {
    	$eMessage = ($_GET['return']);
    	unset($_GET['return']);
    }
    
    ?>

    Solution

    I solved it with
    Code:
    	$("div.file-input-wrapper").mouseover(function(){
    		$("div#errdisplay").html('');
    //		alert("focus");
    		});
    Don't understand why the other approach didn't work.

    thanks...

    Remember... We have a JavaScript Frameworks forum for JQuery, etc type questions
    --> JavaScript Frameworks like JQuery, Angular, Node <--
    ... and please remember to wrap code with forum BBCode tags:-

    [CODE]...[/CODE] [HTML]...[/HTML] [PHP]...[/PHP]

    If you can't think outside the box, you will be trapped forever with no escape...
