Personalize an Alert

Question

I have a code that by clicking the button it opens a new tab. Depending on the condition of the report it shows a Alert that by clicking on OK it closes the tab that was opened. Is there any way I can customize this Alert, to look more beautiful on my site?? My code is in codeigniter.

Answer 1

There is no way to personalize a alert, but you can use some modal, an excellent that I recommend is the Bootbox.js based on Bootstrap. Example:

bootbox.alert("Hello World");

$('#abrir').click(function(event){
  bootbox.alert('Oi, eu sou um alert.', function(){
    bootbox.alert('Oi eu sou um alert chamado apartir de um callback de outro alert.');
  });
});

<div class="container">
  <br>
<button class="btn btn-primary" id="abrir">Abrir Alert</button>
  </div>

Answer 2

You can create a html customized, looking like a modal, and create a function to show the same, as if it were a Alert.

An example would be like this:

Alert.render('Alert Diferente')

#dialogoverlay{
	display: none;
	opacity: .8;
	position: fixed;
	top: 0px;
	left: 0px;
	background: #FFF;
	width: 100%;
	z-index: 10;
}
#dialogbox{
	display: none;
	position: fixed;
	background: #000;
	border-radius:7px; 
	width:550px;
	z-index: 10;
}
#dialogbox > div{ background:#FFF; margin:8px; }
#dialogbox > div > #dialogboxhead{ background: #666; font-size:19px; padding:10px; color:#CCC; }
#dialogbox > div > #dialogboxbody{ background:#333; padding:20px; color:#FFF; }
#dialogbox > div > #dialogboxfoot{ background: #666; padding:10px; text-align:right; }

<script>
function CustomAlert(){
    this.render = function(dialog){
        var winW = window.innerWidth;
        var winH = window.innerHeight;
        var dialogoverlay = document.getElementById('dialogoverlay');
        var dialogbox = document.getElementById('dialogbox');
        dialogoverlay.style.display = "block";
        dialogoverlay.style.height = winH+"px";
        dialogbox.style.left = (winW/2) - (550 * .5)+"px";
        dialogbox.style.top = "100px";
        dialogbox.style.display = "block";
        document.getElementById('dialogboxhead').innerHTML = "Título";
        document.getElementById('dialogboxbody').innerHTML = dialog;
        document.getElementById('dialogboxfoot').innerHTML = '<button onclick="Alert.ok()">OK</button>';
    }
	this.ok = function(){
		document.getElementById('dialogbox').style.display = "none";
		document.getElementById('dialogoverlay').style.display = "none";
	}
}
var Alert = new CustomAlert();
</script>
<div id="dialogoverlay"></div>
<div id="dialogbox">
  <div>
    <div id="dialogboxhead"></div>
    <div id="dialogboxbody"></div>
    <div id="dialogboxfoot"></div>
  </div>
</div>
<h2>Meus Alerts modificados</h2>
<button onclick="alert('Alert Normal')">Alert Normal</button>
<button onclick="Alert.render('Alert Modificado')">Custom Modificado</button>

This way, you can call the same as you call the Alert:

Alert.render('Alert Diferente')

Or at some event javascript.
