Popup, onMouseOver ou...

[Bruno Silva 0]

Pessoal,

 

tenho uma imagem que ao se passar o mouse em cima, quero que apareça um frame com um texto.

 

A solução que bolei foi meio porca então gostaria de outra.

 

Minha solução:

<style type="text/css">
<!--
.div {
	left: 60%;
	top: 56%;
	height: auto;
	width: auto;
	position: absolute;
	background-color: #FFFFFF;
	border-left: 1px solid #8B8682;
	border-bottom: 1px solid #8B8682;
	border-right: 1px solid #8B8682;
	border-top: 1px solid #8B8682;
}
--!>
</style>
<script language="javascript">
	function popup(codigo,cod){
		document.getElementById("pop"+cod).innerHTML=codigo;
	}

	function kill(cod){
		document.getElementById("pop"+cod).innerHTML = "";
	}
</script>

No html:

<span class="div" id="pop1"></span>
<td onMouseOver="popup('<table border=0 cellspacing=0 style=border-collapse:collapse collapse height=1 bordercolor=#111111 cellpadding=0><tr> <td width=100% height=1>Texto</td></tr></table>',1)" onMouseOut="kill(1)">
	<img src="/resolucoes/imagens/ajuda.gif">
</td>

Um frame? Como assim?

 

Aliais frames são estruturas de marcação quase obsoletas e não são mais recomendadas pelo W3C.

O arquivo JS:

/********************************************************************************
*************

ALTTXT V1.6
BY: BRIAN GOSSELIN OF SCRIPTASYLUM.COM

INSTRUCTIONS:

1: PUT THESE DIVS IN THE END OF THE BODY AREA:

   <div id="navtxt" class="navtext" style="visibility:hidden; position:absolute; top:0px; left:-400px; z-index:10000; padding:10px"></div>

2: NEXT, PLACE THIS STYLE DECLARATION IN THE HEAD SECTION OF YOUR PAGE (JUST CHANGE YOUR SETTINGS):

   .navtext {
   width:235px;
   font-size:8pt;
   font-family:verdana;
   border-width:2px;
   border-style:outset;
   border-color:#006BAE;
   layer-background-color:#FFF6D9;
   background-color:#FFF6D9;
   color:black;
   }

3: THEN, SET THE 6 SETTINGS BELOW ( dofade, centertext, xoffset, yoffset, mousefollow, and hideDelay ) AS DESIRED.

4: LASTLY ADD THE MOUSEOVER/MOUSEOUT EVENT HANDLERS TO EACH LINK THAT YOU WANT THIS EFFECT FOR:

	 EXAMPLE: <a href="scriptasylum.com" onmouseover="writetxt('Popup text')" onmouseout="writetxt(0)">Link text</a>

NOTES:

  > YOU CAN CAUSE A BOX *NOT* TO DISAPPEAR ONCE THE MOUSE LEAVES THE LINK BY SIMPLY OMITTING THE
	onmouseout="writetxt(0)" PART. THIS WILL CAUSE THE CURRENT BOX TO REMAIN VISIBLE. THIS IS BEST
	USED WHEN mousefollow MODE IS DISABLED (SET TO false).

  > YOU CAN SET THE PADDING STYLE ATTRIBUTE *ONLY* IN THE navtxt DIV ITSELF AND *NOT* IN THE STYLE
	SHEET AT THE TOP OF THE PAGE. OTHERWISE NS4 DISPLAYS SOME WEIRD BEHAVIOR. ALSO, THE PADDING ATTRIBUTE
	ONLY HAS AN EFFECT IN IE4+ AND NS6+.

********************************************************************************
*************/

var dofade=true;	   // ENABLES FADE-IN EFFECT (FOR IE4+ AND NS6 ONLY)

var centertext=false;  // CENTERS THE TEXT INSIDE THE BOX. YOU CAN'T SIMPLY DO THIS VIA "STYLE" BECAUSE OF NS4.
					   // OTHERWISE, TEXT IS LEFT-JUSTIFIED.

var xoffset=9;		 // HORIZONTAL PIXEL COUNT FROM CURSOR

var yoffset=25;		// VERTICAL PIXEL COUNT FROM CURSOR

var mousefollow=false; // ENABLES MOUSE FOLLOW MODE WHERE THE BOX CONTINUES TO FOLLOW THE MOUSE. SET TO false TO
					   // LOCK THE BOX WHEREVER IT INITIALLY APPEARS.

var hideDelay=300;	 // DELAY IN MILLISECONDS ( 1 SECOND = 1000 MILLISECONDS) FROM WHEN YOU HOVER OUT OF LINK
					   // AND THE BOX DISAPPEARS ONLY WHEN "mousefollow" IS SET TO "false".
					   // THIS WILL GIVE THE USER TIME TO CLICK A LINK OR WHATEVER IN THE BOX BEFORE IT DISAPPEARS.

Pode ser feito assim tambem, é mais simples e mais agradavel para o usuário

 

function mostraTexto(texto) {
		var conteiner = document.getElementById("conteiner");
		var conteudo = conteiner.firstChild;
		
		var novoTexto = document.createTextNode(texto);
		nodoSubstituto = conteiner.replaceChild(novoTexto, conteudo);
		
		conteiner.style.visibility = "visible";
	}
	
	function escondeTexto() {
		conteiner.style.visibility = "hidden";
	}

entao add esse div em quanquer lugar da pagina.

 

<div id="conteiner">Texto antigo</div>

e edita ele com esse CSS na sua folha de estilo. Pra editar a aparencia e a posição do div é so usar CSS

 

#conteiner {
		color:				#FFF	;
		position:			fixed	;
		top:				350px	;
		left:				400px	;
		visibility:			hidden	;
		border:				1px solid black;
		background-color:	#006699	;
		padding:			10px		  ;
		width:				300px	;
		}

Entao chama a função assim

<img src="avulso/imagens/index.png" alt="opa" onmouseover="mostraTexto('Meu Texto')" onmouseout="escondeTexto()" />
