Búsqueda múltiple en Blogger

Otro "truquito" para blogger, esta vez se trata de la caja de búsqueda múltiple que veis en la sidebar.


Es realmente facil:

Primera parte: Elemento HTML
Entramos en nuestra cuenta de blogger y vamos a Plantilla -> Elementos de la página. Una vez ahí añadimos un nuevo elemento HTML / Javascript a nuestra sidebar e incluimos el siguiente código:
<div id="pm-search">
<ul>
<li id="li-h" class="pm-search-selected" onclick="selectH()">mi blog</li><li id="li-g" class="pm-search-unselected" onclick="selectG()">google</li><li id="li-b" class="pm-search-unselected" onclick="selectB()">blogger</li><li id="li-t" class="pm-search-unselected" onclick="selectT()">technorati</li>
</ul>
<div id="pm-search-h">
<form action="http://enimals.blogspot.com/search" method="get">
<input id="pm-f-h" value="" name="q" size="15" type="text"/>
<input value="Buscar" type="submit"/>
</form>
</div>
<div id="pm-search-g">
<form action="http://blogsearch.google.com/blogsearch" method="get">
<input id="pm-f-g" value="" name="as_q" size="15" type="text"/>
<input value="Buscar" type="submit"/>
<input value="enimals.blogspot.com" name="bl_url" type="hidden"/>
</form>
</div>
<div id="pm-search-b">
<form action="http://search.blogger.com/" method="get">
<input id="pm-f-b" value="" name="as_q" size="15" type="text"/>
<input value="Buscar" type="submit"/>
<input value="enimals.blogspot.com" name="bl_url" type="hidden"/>
</form>
</div>
<div id="pm-search-t">
<form action="http://www.technorati.com/search.php" method="post">
<input id="pm-f-t" maxlength="255" name="s" size="15" type="text"/>
<input value="Buscar" type="submit"/>
<input value="searchlet" name="sub" type="hidden"/>
<input value="enimals.blogspot.com" name="from" type="hidden"/>
<input value="n" name="authority" type="hidden"/>
<input value="n" name="language" type="hidden"/>
</form>
</div>
</div>
(sustituiremos enimals por la dirección de nuestro blog y tras finalizar guardaremos el nuevo elemento)


Segunda parte: CSS
Ahora vamos a Plantilla -> Edición de HTML y añadimos el siguiente código:
(Copiar justo antes de la línea ]]></b:skin>)
/** css for the search box */
div#pm-search ul { /* unordered list */
margin-top: 0;
margin-right: 0;
margin-left: 0px;
margin-bottom: 5px;
padding: 0;
}
div#pm-search li { /* each list element */
list-style-type: none; /* don't edit this */
display: inline; /* don't edit this */
cursor: pointer; /* don't edit this */
margin-top: 0;
margin-bottom: 0;
margin-right: 5px;
margin-left: 0px;
text-indent: 0px;
padding: 0;
}
div#pm-search form { /* the search form */
margin: 0;
padding: 0;
}
div#pm-search-h {
display: block; /* don't edit this */
}
div#pm-search-g,
div#pm-search-b,
div#pm-search-t {
display: none; /* don't edit this */
}
div#pm-search input { /* the textbox and submit button */
background-color: transparent;
border: 1px dotted #999;
color: #999;
}
.pm-search-selected { /* which search service is currently selected */
color: #999;
border-bottom: 1px dotted #999;
}
.pm-search-unselected { /* which search services are not selected */
color: #777;
border-bottom: 1px dotted #777;
}


Tercera parte: Javascript
(Copiar justo antes del cierre de la cabecera HTML, </head>)
<script type='text/javascript'>
//<![CDATA[

/***********************************************
* Javascript functions for the search box
* made by PurpleMoggy :)

***********************************************/
var search_which_one = "pm-f-h";
function selectH() {
document.getElementById('li-h').className = 'pm-search-selected';
document.getElementById('li-g').className = 'pm-search-unselected';
document.getElementById('li-b').className = 'pm-search-unselected';
document.getElementById('li-t').className = 'pm-search-unselected';
document.getElementById('pm-search-h').style.display = 'block';
document.getElementById('pm-search-g').style.display = 'none';
document.getElementById('pm-search-b').style.display = 'none';
document.getElementById('pm-search-t').style.display = 'none';
document.getElementById('pm-f-h').value = document.getElementById(search_which_one).value;
search_which_one = "pm-f-h";
}
function selectG() {
document.getElementById('li-h').className = 'pm-search-unselected';
document.getElementById('li-g').className = 'pm-search-selected';
document.getElementById('li-b').className = 'pm-search-unselected';
document.getElementById('li-t').className = 'pm-search-unselected';
document.getElementById('pm-search-h').style.display = 'none';
document.getElementById('pm-search-g').style.display = 'block';
document.getElementById('pm-search-b').style.display = 'none';
document.getElementById('pm-search-t').style.display = 'none';
document.getElementById('pm-f-g').value = document.getElementById(search_which_one).value;
search_which_one = "pm-f-g";
}
function selectB() {
document.getElementById('li-h').className = 'pm-search-unselected';
document.getElementById('li-g').className = 'pm-search-unselected';
document.getElementById('li-b').className = 'pm-search-selected';
document.getElementById('li-t').className = 'pm-search-unselected';
document.getElementById('pm-search-h').style.display = 'none';
document.getElementById('pm-search-g').style.display = 'none';
document.getElementById('pm-search-b').style.display = 'block';
document.getElementById('pm-search-t').style.display = 'none';
document.getElementById('pm-f-b').value = document.getElementById(search_which_one).value;
search_which_one = "pm-f-b";
}
function selectT() {
document.getElementById('li-h').className = 'pm-search-unselected';
document.getElementById('li-g').className = 'pm-search-unselected';
document.getElementById('li-b').className = 'pm-search-unselected';
document.getElementById('li-t').className = 'pm-search-selected';
document.getElementById('pm-search-h').style.display = 'none';
document.getElementById('pm-search-g').style.display = 'none';
document.getElementById('pm-search-b').style.display = 'none';
document.getElementById('pm-search-t').style.display = 'block';
document.getElementById('pm-f-t').value = document.getElementById(search_which_one).value;
search_which_one = "pm-f-t";
}

Como veís el código es muy sencillo y no tendreis problemas en modificar los estilos o incluso añadir / eliminar nuevas búsquedas.
