javascript changing the style

<script>
    function hide()
    {
        document.getElementById("xxx").style.visibility='visible';
    }
</script>
<tr>
    <td>655 3338</td>   
    <td onclick='hide()'>10-May-2013</td>       
</tr>
<tr id='xxx' style='visibility:collapse'>
    <td>655 3338</td>   
    <td>10-May-2013</td>        
</tr>

Good day to all, im a newbie in terms of coding in the language of javascript, im developing a simple hide show, a code above(piece of code) is a table when u click the table cell 10-May-2013 some how a table row below will show, and in that event, im correct? What is missing im my code is when i click again the table cell 10-May-2013 it will hide again, or back to its default style(hide or collapse for table).

You may be better to toggle the row's display property to "none" and "" (empty string) as display is widely supported and seems better suited here.

e.g.

<table>
  <tr><td><button onclick="hideNextRow(this);">Show/Hide next row</button>
  <tr><td>The next row
</table>

<script>

function hideNextRow(node) {

    // Get the parent row
    var row = upTo(node, 'tr');

    // If there is one, get the next row in the table
    if (row) {
        row = row.parentNode.rows[row.rowIndex + 1];
    }

    // If there is a next row, hide or show it depending on the current value
    // of its style.display property
    if (row) {
       row.style.display = row.style.display == 'none'? '' : 'none';
    }
}

// Generic function to go up the DOM to the first parent with a
// tagName of tagname
function upTo(node, tagname) {
  var tagname = tagname.toLowerCase();

  do {
    node = node.parentNode;
  } while (node && node.tagName && node.tagName.toLowerCase() != tagname) 

  // Return the matching node or undefined if not found
  return node && node.tagName && node.tagName.toLowerCase() == tagname? node : void 0;
}
</script>

Try

function hide(){
    if(document.getElementById("xxx").style.visibility != 'visible'){
        document.getElementById("xxx").style.visibility='visible';
    } else {
        document.getElementById("xxx").style.visibility='collapse';
    }
}

Demo: Fiddle
