Ya recorde donde lo habia visto, esta en PHPMyAdmin !!!!!!!
Esta es la función javascript :
Código:
/**
* This array is used to remember mark status of rows in browse mode
*/
var marked_row = new Array;
/**
* Sets/unsets the pointer and marker in browse mode
*
* @param object the table row
* @param integer the row number
* @param string the action calling this script (over, out or click)
* @param string the default background color
* @param string the color to use for mouseover
* @param string the color to use for marking a row
*
* @return boolean whether pointer is set or not
*/

{
var theCells = null;
// 1. Pointer and mark feature are disabled or the browser can't get the
// row -> exits

Y esta es la forma de utilizarlo:
Cita:
<tr onmouseover="setPointer(this, 1, 'over', '#E5E5E5', '#CCFFCC', '#FFCC99');" onmouseout="setPointer(this, 1, 'out', '#E5E5E5', '#CCFFCC', '#FFCC99');" onmousedown="setPointer(this, 1, 'click', '#E5E5E5', '#CCFFCC', '#FFCC99');">
<td align="center" bgcolor="#e5e5e5">
<a href="hola_mundo.htm">Texto de prueba</a>
</td>
</tr>
|
Funciona con todos los navegadores, y gestiona el evento onmousedown, para marcar de otro color los trucos visitados durante esa sesión, por ejemplo.
En cada celda puedes poner un href a documentos diferentes (por ejemplo para editar).
Me parece que el efecto es el que se buscaba, funciona con todos los navegadores, y funciona el boton derecho, y como el link esta en un href el google lo indexa correctamente.
No me merezco el 10, porque la función no es mia (ni mucho menos), solo soy muy observador, y recuerdo donde veo cosas interesantes. |
