Answer 1

This is badly formed HTML. You need to either have a single id or space sperated classes. Either way if you're new I'd look into jQuery.

<div id="sub1">some text</div>

or

<div class="sub1 sub2 sub3">some text</div>

If you had the following HTML:

<div id="sub1">some text</div>
<div id="welcome" style="display:none;">Some welcome message</div>

jQuery

$(document).ready(function() {
    $('#sub1').hover(
      function() { $('#welcome').show(); },
      function() { $('#welcome').hide(); }
    );
});

Javascript

you'd probably want to include the events on your html:

<div id="sub1" onmouseover="showWelcome();" onmouseout="hideWelcome();">some text</div>

then your javascript would have these two functions

function showWelcome()
{
   var welcome = document.getElementById('welcome');
   welcome.style.display = 'block';
}

function hideWelcome()
{
   var welcome = document.getElementById('welcome');
   welcome.style.display = 'none';
}

Please note: this javascript doesn't take cross browser issues into consideration. for this you'd need to elaborate on your code, just another reason to use jquery.

Answer 2

 <div onmouseover='alert("welcome")' id="sub1 sub2 sub3">some text</div>

Or something like this

Answer 3

Tested in IE8 & Firefox

<div id="sub1 sub2 sub3" title="welcome">some text</div>

Answer 4

I'm assuming you want to display the welcome when you mouse over "some text".

As a message box, this will be:

<div id="sub1" onmouseover="javascript:alert('Welcome!');">some text</div>

As a tooltip, it should be:

<div id="sub1" title="Welcome!">some text</div>

As a new div, you can use:

<dic id="sub1" onmouseover="javascript:var mydiv = document.createElement('div'); mydiv.height = 100; mydiv.width = 100; mydiv.zindex = 1000; mydiv.innerHTML = 'Welcome!'; mydiv.position = 'absolute'; mydiv.top = 0; mydiv.left = 0;">some text</div>

You should NEVER contain spaces in the id of an element.

Here's a jQuery solution.

<script type="text/javascript" src="/path/to/your/copy/of/jquery-1.3.2.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
    $("#sub1").mouseover(function() {
        $("#welcome").toggle();
    });
});
</script>

Using this markup:

<div id="sub1">some text</div>
<div id="welcome" style="display:none;">Welcome message</div>

You didn't really specify if (or when) you wanted to hide the welcome message, but this would toggle hiding or showing each time you moused over the text.

Answer 6

Using the title attribute:

<div id="sub1 sub2 sub3" title="some text on mouse over">some text</div>

Answer 7

the prototype way

<div id="sub1" title="some text on mouse over">some text</div>


<script type="text/javascript">//<![CDATA[
  $("sub1").observe("mouseover", function() {
    alert(this.readAttribute("title"));
  });
//]]></script>

include Prototype Lib for testing

<script type="text/javascript" 
  src="http://ajax.googleapis.com/ajax/libs/prototype/1.6.0.2/prototype.js"&gt;&lt;/script&gt;
